Home-dwelling men and women aged ≥ 70 years old, living in South-East Norway were recruited and included in a cross-sectional study. The FI used in the current study was developed according to Rockwood’s frailty index and included 38 variables, resulting in an FI score between 0 and 1 for each participant. Circulating inflammatory markers (IL-6, CRP, IGF-1, cystatin C, cathepsin S, and glycoprotein Acetyls) were analyzed from non-fasting blood samples using ELISA.

The study was conducted in 2014/2015 and has been described previously [Ottestad I, Ulven SM, Øyri LKL, Sandvei KS, Gjevestad GO, Bye A, et al. Reduced plasma concentration of branched-chain amino acids in sarcopenic older subjects: a cross-sectional study. Br J Nutr. 2018;120(4):445-53]. The participants were recruited by the National Register and received an invitation letter by mail. Briefly, a total of 2820 subjects were invited, and 437 subjects participated in the study. The participants met for a single study visit, and data was collected on dietary intake, body weight and composition, physical performance, medical history, cognitive function, risk of malnutrition, anthropometric measurements, blood pressure, heart rate, and quality of life. Non-fasting blood samples were also collected.\"\n",

The FI used in the current study was developed according to Rockwood’s frailty index and included 38 variables, resulting in an FI score between 0 and 1 for each participant. Circulating inflammatory markers (IL-6, CRP, IGF-1, cystatin C, cathepsin S, and glycoprotein Acetyls) were analyzed from non-fasting blood samples using ELISA.

We studied the mechanisms of this impaired exercise response in 20 middle-aged individuals who performed a controlled eight weeks cycling and walking training at 80 % individual VO2max. Participants identified as non-responders in insulin sensitivity (based on Matsuda index) did not differ in pre-intervention parameters compared to high responders. The failure to increase insulin sensitivity after training correlates with impaired up-regulation of mitochondrial fuel oxidation genes in skeletal muscle, and with the suppression of the upstream regulators PGC1α and AMPKα2. The muscle transcriptome of the non-responders is further characterized by an activation of TGFβ and TGFβ target genes, which is associated with increases in inflammatory and macrophage markers. TGFβ1 as inhibitor of mitochondrial regulators and insulin signaling is validated in human skeletal muscle cells. Activated TGFβ1 signaling down-regulates the abundance of PGC1α, AMPKα2, mitochondrial transcription factor TFAM, and of mitochondrial enzymes. Thus, increased TGFβ activity in skeletal muscle can attenuate the improvement of mitochondrial fuel oxidation after training and contribute to the failure to increase insulin sensitivity.\"\n",

Healthy adults (older >65, younger 21-30 years) were recruited at seasonal Influenza Vaccination clinics organized by Yale University Health Services during October to December of 2014 – 2015 seasons. With informed consent, healthy individuals were recruited as per a protocol approved by Human Investigations Committee of the Yale University School of Medicine. Each subject was evaluated by a screening questionnaire determining self-reported demographic information, height, weight, medications and comorbid conditions. Participants with acute illness two weeks prior to vaccination were excluded from study. Blood samples were collected into BD Vacutainer Sodium Heparin tube at four different time points, once prior to administration of vaccine and three time points after vaccination on days 2, 7 and 28. Peripheral Blood Mononuclear Cells (PBMC) were isolated from heparinized blood using Histopaque 1077 in gradient centrifugation. About 1.0x10^7 freshly isolated PBMC were lysed in Triso and immediately stored in -800C. Total RNA in aqueous phase of Trisol - Chloroform was isolated in an automated QiaCube instrument using miRNeasy according to manufacturer’s instructions. Integrity of RNA samples were assessed by Agilent 2100 BioAnalyser Samples were processed for cRNA generation using Illumina TotalPrep cRNA Amplification Kit and subsequently hybridized to Human HT12-V4.0 BeadChip at Yale Center for Genomic Analysis (YGCA).\"\n",

With informed consent, healthy individuals were recruited as per a protocol approved by Human Investigations Committee of the Yale University School of Medicine. Each subject was evaluated by a screening questionnaire determining self-reported demographic information, height, weight, medications and comorbid conditions. Participants with acute illness two weeks prior to vaccination were excluded from study. Blood samples were collected into BD Vacutainer Sodium Heparin tube at four different time points, once prior to administration of vaccine and three time points after vaccination on days 2, 7 and 28. Peripheral Blood Mononuclear Cells (PBMC) were isolated from heparinized blood using Histopaque 1077 in gradient centrifugation. About 1.0x10^7 freshly isolated PBMC were lysed in Triso and immediately stored in -800C. Total RNA in aqueous phase of Trisol - Chloroform was isolated in an automated QiaCube instrument using miRNeasy according to manufacturer’s instructions.

We found that  SLIT2 was overexpressed in the liver of patients with NASH, PSC and other chronic liver diseases. We also examined the microarray data of the human liver tissue samples for the transcriptomic signatures and found that in the different types of liver diseases the gene signature of PMSCs/PMSC-MFs was increased compared to normal liver, and correlated with the expression of ACTA2, COL1A1 and vWF.\"\n",

We found that  SLIT2 was overexpressed in the liver of patients with NASH, PSC and other chronic liver diseases. We also examined the microarray data of the human liver tissue samples for the transcriptomic signatures and found that in the different types of liver diseases the gene signature of PMSCs/PMSC-MFs was increased compared to normal liver, and correlated with the expression of ACTA2, COL1A1 and vWF.\n",

+      "!Series_summary\t\"A key step in bringing gene expression data into clinical practice is the conduct of large studies to confirm preliminary models. The performance of such confirmatory studies and the transition to clinical practice requires that microarray data from different laboratories are comparable and reproducible. We designed a study to assess the comparability of data from four laboratories that will conduct a larger microarray profiling confirmation project in lung adenocarcinomas. To test the feasibility of combining data across laboratories, frozen tumor tissues, cell line pellets, and purified RNA samples were analyzed at each of the four laboratories. Samples of each type and several subsamples from each tumor and each cell line were blinded before being distributed. The laboratories followed a common protocol for all steps of tissue processing, RNA extraction, and microarray analysis using Affymetrix Human Genome U133A arrays. High within-laboratory and between-laboratory correlations were observed on the purified RNA samples, the cell lines, and the frozen tumor tissues. Intraclass correlation within laboratories was only slightly stronger than between laboratories, and the intraclass correlation tended to be weakest for genes expressed at low levels and showing small variation. Finally, hierarchical cluster analysis revealed that the repeated samples clustered together regardless of the laboratory in which the experiments were done. The findings indicate that under properly controlled conditions it is feasible to perform complete tumor microarray analysis, from tissue processing to hybridization and scanning, at multiple independent laboratories for a single study.\"\n",

The performance of such confirmatory studies and the transition to clinical practice requires that microarray data from different laboratories are comparable and reproducible. We designed a study to assess the comparability of data from four laboratories that will conduct a larger microarray profiling confirmation project in lung adenocarcinomas. To test the feasibility of combining data across laboratories, frozen tumor tissues, cell line pellets, and purified RNA samples were analyzed at each of the four laboratories. Samples of each type and several subsamples from each tumor and each cell line were blinded before being distributed. The laboratories followed a common protocol for all steps of tissue processing, RNA extraction, and microarray analysis using Affymetrix Human Genome U133A arrays. High within-laboratory and between-laboratory correlations were observed on the purified RNA samples, the cell lines, and the frozen tumor tissues. Intraclass correlation within laboratories was only slightly stronger than between laboratories, and the intraclass correlation tended to be weakest for genes expressed at low levels and showing small variation. Finally, hierarchical cluster analysis revealed that the repeated samples clustered together regardless of the laboratory in which the experiments were done. The findings indicate that under properly controlled conditions it is feasible to perform complete tumor microarray analysis, from tissue processing to hybridization and scanning, at multiple independent laboratories for a single study.\"\n",

In this study we performed in-depth analyses of normal kidney tissue transcriptomes from TCGA and demonstrate that the histological variability in cellularity, inherent in the kidney architecture, lead to considerable transcriptional differences between samples. This should be considered when comparing expression profiles of normal and cancerous kidney tissues. We exploited these differences to define renal cell-specific gene signatures and used these as framework to analyze renal cell carcinoma (RCC) ontogeny. Chromophobe RCCs express FOXI1-driven genes that define collecting duct intercalated cells whereas HNF-regulated genes, specific for proximal tubule cells, are an integral part of clear cell and papillary RCC transcriptomes. These networks may be used as framework for understanding the interplay between genomic changes in RCC subtypes and the lineage-defining regulatory machinery of their non-neoplastic counterparts.\"\n",
+      "!Series_overall_design\t\"Samples from different parts of the kidneys were procured using core-sampling from approximately 10 mm thick sections obtained from nephrectomized patients in surgery for renal neoplasms. Sampling was performed in the part of the kidney that was farthest from the tumor. Sections were thereafter embedded and hematoxylin-eosin stained allowing for approximation of the respective site in kidney from which the sample was obtained. In all cases a histologically normal kidney histology was confirmed. In all, 53 samples from 5 different renal specimens were included in the analysis.\"\n",

In this study we performed in-depth analyses of normal kidney tissue transcriptomes from TCGA and demonstrate that the histological variability in cellularity, inherent in the kidney architecture, lead to considerable transcriptional differences between samples. This should be considered when comparing expression profiles of normal and cancerous kidney tissues. We exploited these differences to define renal cell-specific gene signatures and used these as framework to analyze renal cell carcinoma (RCC) ontogeny. Chromophobe RCCs express FOXI1-driven genes that define collecting duct intercalated cells whereas HNF-regulated genes, specific for proximal tubule cells, are an integral part of clear cell and papillary RCC transcriptomes. These networks may be used as framework for understanding the interplay between genomic changes in RCC subtypes and the lineage-defining regulatory machinery of their non-neoplastic counterparts.\"\n",
+      "Line 7: !Series_overall_design\t\"Samples from different parts of the kidneys were procured using core-sampling from approximately 10 mm thick sections obtained from nephrectomized patients in surgery for renal neoplasms. Sampling was performed in the part of the kidney that was farthest from the tumor. Sections were thereafter embedded and hematoxylin-eosin stained allowing for approximation of the respective site in kidney from which the sample was obtained. In all cases a histologically normal kidney histology was confirmed. In all, 53 samples from 5 different renal specimens were included in the analysis.\"\n",

+      "!Series_summary\t\"Vitamin D deficiency is common among older adults and has been linked to muscle weakness. Vitamin D supplementation has been proposed as a strategy to improve muscle function in older adults. The aim of this study was to investigate the effect of calcifediol (25-hydroxycholecalciferol) on whole genome gene expression in skeletal muscle of vitamin D deficient frail older adults. A double-blind placebo controlled trial was conducted in vitamin D deficient frail older adults (aged above 65), characterized by blood 25-hydroxycholecalciferol concentrations between 20 and 50 nmol/L. Subjects were randomized across the placebo group (n=12) and the calcifediol group (n=10, 10 µg per day). Muscle biopsies were obtained before and after six months of calcifediol or placebo supplementation and subjected to whole genome gene expression profiling using Affymetrix HuGene 2.1ST arrays. Expression of the vitamin D receptor gene was virtually undetectable in human skeletal muscle biopsies. Calcifediol supplementation led to a significant increase in blood 25-hydroxycholecalciferol levels compared to the placebo group. No difference between treatment groups was observed on strength outcomes. The whole transcriptome effects of calcifediol and placebo were very weak. Correcting for multiple testing using false discovery rate did not yield any differentially expressed genes using any sensible cut-offs. P-values were uniformly distributed across all genes, suggesting that low p-values are likely to be false positives. Partial least squares-discriminant analysis and principle component analysis was unable to separate treatment groups. Calcifediol supplementation did not affect the skeletal muscle transcriptome in frail older adults. Our findings indicate that vitamin D supplementation has no effects on skeletal muscle gene expression, suggesting that skeletal muscle may not be a direct target of vitamin D in older adults.\"\n",

To establish genomic pathogenesis of RP, we performed the microarray analysis for comparing the gene expressions among renal papillary RP and normal tissue of 23 CaOx and 6 calcium phosphate (CaP) stone formers, and normal papillary tissue of 7 control patients. Compare to normal papillary tissue, RP tissue contained up-regulation of lipocalin 2, interleukin 11, prostaglandin-endoperoxide synthase 1, glutathione peroxidase 3, and monocyte to macrophage differentiation, whereas down-regulation of solute carrier family 12 member 1  and sodium leak channel non selective (either > 2.0- or 0.5-fold, p <0.01). The network and toxicity analysis showed these genes had association with activated mitogen-activated protein kinase, Akt/ phosphatidylinositol 3-kinase pathway, and pro-inflammatory cytokines, which caused renal injury and oxidative stress.\"\n",

+      "!Series_summary\t\"The aim of this study is to design and validate a test, METAHEALTH-TEST, based on gene expression analysis in blood cells, to quickly and easily analyse metabolic health. This test will be used to analyse metabolic improvement in overweight/obese individuals and in metabolically obese normal-weight (MONW) individuals after undergoing a weight loss intervention and/or an intervention for improvement in eating habits and lifestyle. Obesity and its medical complications are a serious health problem today. Using peripheral blood mononuclear cells (PBMC) as an easily obtainable source of transcriptomic biomarkers would allow to deepen into the knowledge of adaptations in response to increased adiposity that occur in internal homeostatic tissues, without the need of using invasive biopsies. Moreover, if PBMC were able to reflect lipid metabolism gene expression pattern recovery as a result of weight loss, it would provide valuable information to know the efficacy of therapies aimed at weight loss and, in any case, it would allow to personalize them according to the evolution of obese patients until the desired metabolic recovery is achieved.\"\n",
+      "!Series_overall_design\t\"Apparently healthy subjects aged 18 to 45 years old, including men and women were recruited and classified into two groups depending on their body mass index (BMI). Normal-weight (NW) group (BMI <25 kg/m2) was composed of 20 subjects and overweight-obese (OW-OB) group (BMI ≥25 kg/m2) of 27 subjects. The inclusion criteria were: subjects with no chronic disease who did not take regular medication or drugs. To avoid potential bias, both groups include approx. 50% men/women and there was no difference in their average age. We recruited 6 additional NW individuals presenting 1 metabolic alteration related to MetS (high plasma total or LDL-cholesterol, plasma triglycerides, or plasma C-reactive protein (CRP) concentrations, or hypertension). They were classified as  metabolically obese normal-weight (MONW) individuals. Subjects from the OW-OB group followed a 6-month weight loss program which included a low-calorie food plan (30% reduction in the individual energy requirements) with dietary sessions and exercise counselling. Dietary sessions were offered by a nutritionist every fifteen days who provided face-to-face counselling that was individually adjusted to each subject with the aim of reducing 5% to 10% of initial body weight. Neither dietary supplements nor vitamins were provided and all participants consumed self-selected foods. 20 out of the 27 OW-OB subjects who started the study completed the 6-month weight loss program. All the volunteers underwent what we called the fasting test which consisted of collecting blood samples after 4 and after 6 hours after having had a standard breakfast. The blood extractions were performed by skilled health personnel; once in the NW and MONW groups,and three times (at the baseline point, and after 3 and 6 months of nutritional intervention) in the OW-OB group. Blood was collected using Vacutainer® EDTA tubes. After blood collection, the samples were processed immediately to obtain the PBMC fraction. PBMC were isolated using Ficoll-Paque Plus density gradient media. Total RNA from PBMC samples was extracted using Tripure Reagent and then purified with E.Z.N.A. Total RNA Kit I and precipitated with isopropanol. Isolated RNA was quantified using a NanoDrop ND 1000 spectrophotometer.

This test will be used to analyse metabolic improvement in overweight/obese individuals and in metabolically obese normal-weight (MONW) individuals after undergoing a weight loss intervention and/or an intervention for improvement in eating habits and lifestyle. Obesity and its medical complications are a serious health problem today. Using peripheral blood mononuclear cells (PBMC) as an easily obtainable source of transcriptomic biomarkers would allow to deepen into the knowledge of adaptations in response to increased adiposity that occur in internal homeostatic tissues, without the need of using invasive biopsies. Moreover, if PBMC were able to reflect lipid metabolism gene expression pattern recovery as a result of weight loss, it would provide valuable information to know the efficacy of therapies aimed at weight loss and, in any case, it would allow to personalize them according to the evolution of obese patients until the desired metabolic recovery is achieved.\"\n",
+      "Line 7: !Series_overall_design\t\"Apparently healthy subjects aged 18 to 45 years old, including men and women were recruited and classified into two groups depending on their body mass index (BMI). Normal-weight (NW) group (BMI <25 kg/m2) was composed of 20 subjects and overweight-obese (OW-OB) group (BMI ≥25 kg/m2) of 27 subjects. The inclusion criteria were: subjects with no chronic disease who did not take regular medication or drugs. To avoid potential bias, both groups include approx. 50% men/women and there was no difference in their average age. We recruited 6 additional NW individuals presenting 1 metabolic alteration related to MetS (high plasma total or LDL-cholesterol, plasma triglycerides, or plasma C-reactive protein (CRP) concentrations, or hypertension). They were classified as  metabolically obese normal-weight (MONW) individuals. Subjects from the OW-OB group followed a 6-month weight loss program which included a low-calorie food plan (30% reduction in the individual energy requirements) with dietary sessions and exercise counselling. Dietary sessions were offered by a nutritionist every fifteen days who provided face-to-face counselling that was individually adjusted to each subject with the aim of reducing 5% to 10% of initial body weight. Neither dietary supplements nor vitamins were provided and all participants consumed self-selected foods. 20 out of the 27 OW-OB subjects who started the study completed the 6-month weight loss program. All the volunteers underwent what we called the fasting test which consisted of collecting blood samples after 4 and after 6 hours after having had a standard breakfast. The blood extractions were performed by skilled health personnel; once in the NW and MONW groups,and three times (at the baseline point, and after 3 and 6 months of nutritional intervention) in the OW-OB group. Blood was collected using Vacutainer® EDTA tubes. After blood collection, the samples were processed immediately to obtain the PBMC fraction. PBMC were isolated using Ficoll-Paque Plus density gradient media. Total RNA from PBMC samples was extracted using Tripure Reagent and then purified with E.Z.N.A. Total RNA Kit I and precipitated with isopropanol. Isolated RNA was quantified using a NanoDrop ND 1000 spectrophotometer. Its integrity was confirmed using agarose gel electrophoresis and the RIN tool using the Agilent 2100 Bioanalyzer System. For the microarray experiment the following samples were selected: 12 paired samples from the NW group after both 4h and 6h of fasting, 12 paired samples from the OW-OB group after both 4h and 6h of fasting, 12 paired samples from the OW-OB group after the 6-month weight loss programm after both 4h and 6h of fasting, and 6 samples from the MONW group after 6h of fasting at the beginning of the study.

+      "!Series_summary\t\"Most loci identified in genome wide association studies (GWAS) of complex traits reside in non-coding DNA and may contribute to phenotype via changes in gene regulation. The discovery of expression quantitative trait loci (?eQTLs?) can thus be used to more precisely identify modest but real disease associations and provide insights into their underlying molecular mechanisms. This is particularly true for analyses of expression in non-transformed cells from tissues relevant to the complex traits of interest. We have conducted two independent studies to identify genetic, including both SNPs and copy-number variants, and environmental determinants of human liver gene expression variation. We analyzed two sets of primary livers (primary dataset: n=220; replication dataset: n=60) using Agilent and Illumina expression arrays and Illumina SNP genotyping (550K). At least 30% of genetic and non-genetic factors that meet genome-wide significance (p <1 x10-9) in one study fail to replicate in the second study, suggesting that artifacts, like unknown SNPs that affect RNA-probe hybridization or hidden confounding variables, often result in statistically significant but biologically irrelevant correlations. These data confirm the value of independent replications to enrich for truly predictive eQTLs, and given our study design we are able to identify hundreds of reproducible correlations. We show that such information can be used to provide insights into disease-relevant phenotypes, with specific examples including eQTLs related to lipid levels (e.g. LDL cholesterol), immune system function (e.g. HLA), and drug response (e.g. warfarin). Furthermore, in the interest of both fine-mapping and mechanistic annotation, we hypothesized that promoters and 3?UTRs are enriched for causal eQTL variants. Therefore, we re-sequenced the promoter and 3?UTR regions of 25 genes with eQTLs, cloned each discovered haplotype, and quantified their impact on transcription using a luciferase-based assay. These data reveal multiple examples of robust, haplotype-specific in vitro functional differences that correlate directly with in vivo expression levels. This suggests that many eQTLs can be rapidly fine-mapped to one or a few single-nucleotide variants and mechanistically characterized using such assays. Integration of functional assays with eQTL discovery, and eQTLs with complex trait associations, is a powerful means to exploit GWAS data and improve their biological interpretability.\"\n",

+      "Line 7: !Series_summary\t\"Most loci identified in genome wide association studies (GWAS) of complex traits reside in non-coding DNA and may contribute to phenotype via changes in gene regulation. The discovery of expression quantitative trait loci (?eQTLs?) can thus be used to more precisely identify modest but real disease associations and provide insights into their underlying molecular mechanisms. This is particularly true for analyses of expression in non-transformed cells from tissues relevant to the complex traits of interest. We have conducted two independent studies to identify genetic, including both SNPs and copy-number variants, and environmental determinants of human liver gene expression variation. We analyzed two sets of primary livers (primary dataset: n=220; replication dataset: n=60) using Agilent and Illumina expression arrays and Illumina SNP genotyping (550K). At least 30% of genetic and non-genetic factors that meet genome-wide significance (p <1 x10-9) in one study fail to replicate in the second study, suggesting that artifacts, like unknown SNPs that affect RNA-probe hybridization or hidden confounding variables, often result in statistically significant but biologically irrelevant correlations. These data confirm the value of independent replications to enrich for truly predictive eQTLs, and given our study design we are able to identify hundreds of reproducible correlations. We show that such information can be used to provide insights into disease-relevant phenotypes, with specific examples including eQTLs related to lipid levels (e.g. LDL cholesterol), immune system function (e.g. HLA), and drug response (e.g. warfarin). Furthermore, in the interest of both fine-mapping and mechanistic annotation, we hypothesized that promoters and 3?UTRs are enriched for causal eQTL variants. Therefore, we re-sequenced the promoter and 3?UTR regions of 25 genes with eQTLs, cloned each discovered haplotype, and quantified their impact on transcription using a luciferase-based assay. These data reveal multiple examples of robust, haplotype-specific in vitro functional differences that correlate directly with in vivo expression levels. This suggests that many eQTLs can be rapidly fine-mapped to one or a few single-nucleotide variants and mechanistically characterized using such assays. Integration of functional assays with eQTL discovery, and eQTLs with complex trait associations, is a powerful means to exploit GWAS data and improve their biological interpretability.\"\n",

Biological mechanisms explaining lack of disease-response  are largely unknown. To identify mechanisms of response and survival before CAR T manufacturing in 95 R/R LBCL receiving tisagenlecleucel or axicabtagene ciloleucel, we performed phenotypic, transcriptomic and functional evaluations of leukapheresis products (LK).  Transcriptomic profiling of T cells in LK, revealed a signature composed of 4 myeloid genes able to identify patients with very short progression-free survival, highlighting the role of monocytes in CAR T therapy response. Accordingly, response and survival were negatively influenced by high circulating absolute monocyte counts at the time of leukapheresis, and the combined evaluation of peripheral blood monocytes and the four-gene signature in LK, identifies LBCL patients at very high risk of progression after CAR T.\"\n",

Biological mechanisms explaining lack of disease-response  are largely unknown. To identify mechanisms of response and survival before CAR T manufacturing in 95 R/R LBCL receiving tisagenlecleucel or axicabtagene ciloleucel, we performed phenotypic, transcriptomic and functional evaluations of leukapheresis products (LK).  Transcriptomic profiling of T cells in LK, revealed a signature composed of 4 myeloid genes able to identify patients with very short progression-free survival, highlighting the role of monocytes in CAR T therapy response. Accordingly, response and survival were negatively influenced by high circulating absolute monocyte counts at the time of leukapheresis, and the combined evaluation of peripheral blood monocytes and the four-gene signature in LK, identifies LBCL patients at very high risk of progression after CAR T.\"\n",

+      "!Series_summary\t\"The phase 3 ZUMA-7 trial in second-line large B-cell lymphoma demonstrated superiority of anti-CD19 CAR T-cell therapy (axicabtagene ciloleucel; axi-cel) over standard of care (SOC; salvage chemotherapy followed by hematopoietic transplantation). Here, we present a prespecified exploratory analysis examining the association between pretreatment tumor characteristics and the efficacy of axi-cel versus SOC. B-cell gene expression signature (GES) and CD19 expression significantly associated with improved event-free survival (EFS) for axi-cel (P=.0002 for B-cell GES; P=.0165 for CD19 expression) but not SOC (P=.9374 for B-cell GES; P=.5526 for CD19 expression). Axi-cel showed superior EFS over SOC irrespective of B-cell GES and CD19 expression (P=8.56e–9 for B-cell GES high; P=.0019 for B-cell GES low; P=3.85e–9 for CD19 gene high; P=.0017 for CD19 gene low). Low CD19 expression in malignant cells correlated with a tumor GES consisting of immune suppressive stromal and myeloid genes, highlighting the inter-relation between malignant cell features and immune contexture substantially impacting axi-cel outcomes. Tumor burden, lactate dehydrogenase, and cell-of-origin impacted SOC more than axi-cel outcomes. T-cell activation and B-cell GES, which are associated with improved axi-cel outcome, decreased with increasing lines of therapy. These data highlight differences in resistance mechanisms to axi-cel and SOC and support earlier intervention with axi-cel.\"\n",

+      "Line 6: !Series_summary\t\"The phase 3 ZUMA-7 trial in second-line large B-cell lymphoma demonstrated superiority of anti-CD19 CAR T-cell therapy (axicabtagene ciloleucel; axi-cel) over standard of care (SOC; salvage chemotherapy followed by hematopoietic transplantation). Here, we present a prespecified exploratory analysis examining the association between pretreatment tumor characteristics and the efficacy of axi-cel versus SOC. B-cell gene expression signature (GES) and CD19 expression significantly associated with improved event-free survival (EFS) for axi-cel (P=.0002 for B-cell GES; P=.0165 for CD19 expression) but not SOC (P=.9374 for B-cell GES; P=.5526 for CD19 expression). Axi-cel showed superior EFS over SOC irrespective of B-cell GES and CD19 expression (P=8.56e–9 for B-cell GES high; P=.0019 for B-cell GES low; P=3.85e–9 for CD19 gene high; P=.0017 for CD19 gene low). Low CD19 expression in malignant cells correlated with a tumor GES consisting of immune suppressive stromal and myeloid genes, highlighting the inter-relation between malignant cell features and immune contexture substantially impacting axi-cel outcomes. Tumor burden, lactate dehydrogenase, and cell-of-origin impacted SOC more than axi-cel outcomes. T-cell activation and B-cell GES, which are associated with improved axi-cel outcome, decreased with increasing lines of therapy. These data highlight differences in resistance mechanisms to axi-cel and SOC and support earlier intervention with axi-cel.\"\n",

Expression array (n=53 NASH-HCC; n=74 NASH) and whole exome sequencing (n=50 NASH-HCC) data were compared to HCCs of other aetiologies (n=184).

ACVR2A mutation rates were higher in NASH-HCC than in other HCC aetiologies (10% versus 3%, p<0.05). In vitro, ACVR2A silencing prompted a significant increase in cell proliferation in HCC cells. We identified a novel mutational signature (MutSig-NASH-HCC) significantly associated with NASH-HCC (16% vs 2% in viral/alcohol-HCC, p=0.03). Tumour mutational burden (TMB) was higher in non-cirrhotic than in cirrhotic NASH-HCCs (1.45 versus 0.94 mutations/Mb; p<0.0017). Compared to other aetiologies of HCC, NASH-HCCs were enriched in bile and fatty acid signalling, oxidative stress and inflammation, and presented a higher fraction of Wnt/TGF-β proliferation subclass tumours (42% versus 26%, p=0.01) and a lower prevalence of the CTNNB1 subclass. Compared to other aetiologies, NASH-HCC showed a significantly higher prevalence of immunosuppressive cancer field. In three murine models of NASH-HCC key features of human NASH-HCC were preserved.\"\n",

+      "!Series_summary\t\"The purpose of this study was to use chemical similarity evaluations, transcriptional profiling, in vitro toxicokinetic data and physiologically based pharmacokinetic (PBPK) models to support read across for a series of branched carboxylic acids using valproic acid (VPA), a known developmental toxicant, as a comparator. The chemicals included 2-propylpentanoic acid (VPA), 2-ethylbutanoic acid (EBA), 2-ethylhexanoic acid (EHA), 2-methylnonanoic acid (MNA), 2-hexyldecanoic acid (HDA), 2-propylnonanoic acid (PNA), dipentyl acetic acid (DPA) or 2-pentylheptanoic acid (PHA), octanoic acid (OA, a straight chain alkyl acid) and 2-ethylhexanol. Transcriptomics was evaluated in four cell types (A549, HepG2, MCF7 and iCell cardiomyocytes) 6 hours after exposure to 3 concentrations of the compounds, using the L1000 platform. The transcriptional profiling data indicate that two- or three-carbon alkyl substituents at the alpha position of the carboxylic acid (EHA and PNA) elicit a transcriptional profile similar to the one elicited by VPA. The transcriptional profile is different for the other chemicals tested, which provides support for limiting read across from VPA to much shorter and longer acids. Molecular docking models for histone deacetylases, the putative target of VPA, provides a possible mechanistic explanation for the activity cliff elucidated by transcriptomics. In vitro toxicokinetic data was utilized in a PBPK model to estimate internal dosimetry. The PBPK modeling data show that as the branched chain increases, predicted plasma Cmax decreases. This work demonstrates how transcriptomics and other mode of action-based methods can improve read across.\"\n",
+      "!Series_overall_design\t\"Four cell types were used for the transcriptomic experiments: MCF-7 (breast epithelial adenocarcinoma), A549 (lung epithelial carcinoma), HepG2 (hepatocellular carcinoma) and iCell cardiomyocytes (derived from induced pluripotent stem cells, FujiFilm Cellular Dynamics, Madison, WI). MCF-7, A549 and HepG2 cells were purchased from American Type Culture Collection (Manassas, VA) and grown in phenol red-free DMEM media containing 10% serum (Invitrogen, Carlsbad, CA). The iCell cardiomyocytes were grown in a proprietary maintenance medium (FujiFilm Cellular Dynamics, Inc.) for 168 h before chemical treatment. All cell cultures were performed in 96-well plates with 12 DMSO controls on each plate. Cells were seeded on 96 well plates and treated with 3 concentrations of each chemical DMSO for 6 h. Chemical samples were randomized across the plate and DMSO were placed on fixed well locations for each plate. Following 6 h treatment, Cells were lysed with 50 μl of Genometry Lysis Buffer to each well, sealed and stored at -80⁰C. Cell lysate plates were shipped frozen to Genometry for L1000 assasy.\"\n",

+      "!Series_summary\t\"Background & Aims: Cellular responses induced by surgical procedure or ischemia-reperfusion injury (IRI) may severely alter transcriptome profiles. We have investigated this effect to obtain insight into molecular ischemia responses during surgical procedures and characterize pre-analytical effects impacting on molecular analyses. Methods: 143 non-malignant liver samples were obtained from 30 patients at different time points of ischemia during surgery from two individual cohorts, treated either with the Pringle maneuver or total vascular exclusion. Transcriptomics profiles were analyzed by Affymetrix microarrays and expression of selected mRNAs was validated by RT-qPCR. Results: Transcriptional profiles of both cohorts displayed 179 genes that were mutually deregulated confirming elevated cytokine signaling, and NFkB as the dominant pathways in ischemia response. Contrary to ischemia, reperfusion induced pro-apoptotic and pro-inflammatory cascades involving TNF, NFkB and MAPK pathways. FOS and JUN were down-regulated in steatosis compared to their up-regulation in normal livers. Surprisingly, molecular signatures of underlying primary and secondary cancers were clearly present in the non-tumor tissue. Conclusions: We identified transcripts mutually deregulated during ischemia and reperfusion injury in both cohorts that can be used to monitor ischemia during liver surgery and highlight the importance of pre-analytical quality control. The marked inter-patient variability might reflect differences in individual stress responses and impact of underlying disease conditions. Furthermore, we provide a comprehensive and pre-analytically highly standardized in vivo transcriptome profile of histologically normal liver and identified 230 genes with substantial pre-analytical robustness (<2 % covariation across both cohorts) that might serve as reference genes and could be particularly suited for future diagnostic applications.

+      "!Series_summary\t\"BACKGROUND: The molecular mechanisms driving the progression from early chronic liver disease (eCLD) to cirrhosis and, finally, acute-on-chronic liver failure (ACLF) are largely unknown. Thus, the aim of this work is to develop a network-based approach to investigate molecular pathways driving progression from eCLD to ACLF. We created 9 liver-specific biological networks capturing key pathophysiological processes potentially related to CLD. We used these networks as framework to perform gene set enrichment analyses(GSEA) and create dynamic profiles of disease progression.  RESULTS: Principal component analyses revealed that samples clustered according to the disease stage. GSEA analyses of the defined processes showed an up-regulation of inflammation, fibrosis and apoptosis networks throughout disease progression. Interestingly, we did not find significant gene expression differences between CC and DC, while ACLF showed acute expression changes in all the defined liver-related networks. The analyses of disease progression patterns identified ascending and descending expression profiles associated to ACLF onset. Functional analyses showed that ascending profiles were associated to inflammation, fibrosis, apoptosis, senescence and carcinogenesis networks, while descending profiles were mainly related to oxidative stress and genetic factors. We confirmed by qPCR the up-regulation of 4 genes of the ascending profile CXCL-6, KRT-18, SPINK-1, and ITGA2, and validated our findings on an independent patient’s cohort.  CONCLUSION: ACLF is characterized by a specific hepatic gene expression pattern related to inflammation, fibrosis, apoptosis, senescence and carcinogenesis processes. Moreover, the observed profile is significantly different from that of compensated and decompensated cirrhosis, supporting thus the hypothesis that ACLF should be considered a distinct entity.\"\n",

+      "!Series_summary\t\"Background/Aims: There is a major unmet need to assess prognostic impact of anti-fibrotics in clinical trials due to the slow rate of liver fibrosis progression. We aimed to develop a surrogate biomarker to predict future fibrosis progression.  Methods: A Fibrosis Progression Signature (FPS) was defined to predict fibrosis progression within 5 years in HCV and NAFLD patients with no to minimal fibrosis at baseline (n=421), and validated in an independent NAFLD cohort (n=78). The FPS was used to assess response to 13 candidate anti-fibrotics in organotypic ex vivo cultures of clinical fibrotic liver tissues (n=78), and cenicriviroc in NASH patients enrolled in a clinical trial (n=19, NCT02217475). A serum-protein-based surrogate FPS (FPSec) was developed and technically evaluated in a liver disease patient cohort (n=79).  Results: A 20-gene FPS was defined and validated in an independent NAFLD cohort (aOR=10.93, AUROC=0.86). Among computationally inferred fibrosis-driving FPS genes, BCL2 was confirmed as a potential pharmacological target using clinical liver tissues. Systematic ex vivo evaluation of 13 candidate anti-fibrotics identified rational combination therapies based on epigallocatechin gallate, some of which were validated for enhanced anti-fibrotic effect in ex vivo culture of clinical liver tissues. In NASH patients treated with cenicriviroc, FPS modulation was associated with 1-year fibrosis improvement accompanied by suppression of the E2F pathway. Induction of PPARalpha pathway was absent in patients without fibrosis improvement, suggesting benefit of combining PPARalpha agonism to improve anti-fibrotic efficacy of cenicriviroc. A 7-protein FPSec panel showed concordant prognostic prediction with FPS.  Conclusion: FPS predicts long-term fibrosis progression in an etiology-agnostic manner, which can inform anti-fibrotic drug development.\"\n",

The FPS was used to assess response to 13 candidate anti-fibrotics in organotypic ex vivo cultures of clinical fibrotic liver tissues (n=78), and cenicriviroc in NASH patients enrolled in a clinical trial (n=19, NCT02217475). A serum-protein-based surrogate FPS (FPSec) was developed and technically evaluated in a liver disease patient cohort (n=79).\"\n",

Among computationally inferred fibrosis-driving FPS genes, BCL2 was confirmed as a potential pharmacological target using clinical liver tissues. Systematic ex vivo evaluation of 13 candidate anti-fibrotics identified rational combination therapies based on epigallocatechin gallate, some of which were validated for enhanced anti-fibrotic effect in ex vivo culture of clinical liver tissues. In NASH patients treated with cenicriviroc, FPS modulation was associated with 1-year fibrosis improvement accompanied by suppression of the E2F pathway. Induction of PPAR-alfa pathway was absent in patients without fibrosis improvement, suggesting benefit of combining PPAR-alfa agonism to improve anti-fibrotic efficacy of cenicriviroc. A 7-protein FPSec panel showed concordant prognostic prediction with FPS.\"\n",

The FPS was used to assess response to 13 candidate anti-fibrotics in organotypic ex vivo cultures of clinical fibrotic liver tissues (n=78), and cenicriviroc in NASH patients enrolled in a clinical trial (n=19, NCT02217475). A serum-protein-based surrogate FPS (FPSec) was developed and technically evaluated in a liver disease patient cohort (n=79).\"\n",
+      "!Series_summary\t\"Results: A 20-gene FPS was defined and validated in an independent NAFLD cohort (aOR=10.93, AUROC=0.86). Among computationally inferred fibrosis-driving FPS genes, BCL2 was confirmed as a potential pharmacological target using clinical liver tissues. Systematic ex vivo evaluation of 13 candidate anti-fibrotics identified rational combination therapies based on epigallocatechin gallate, some of which were validated for enhanced anti-fibrotic effect in ex vivo culture of clinical liver tissues. In NASH patients treated with cenicriviroc, FPS modulation was associated with 1-year fibrosis improvement accompanied by suppression of the E2F pathway. Induction of PPAR-alfa pathway was absent in patients without fibrosis improvement, suggesting benefit of combining PPAR-alfa agonism to improve anti-fibrotic efficacy of cenicriviroc. A 7-protein FPSec panel showed concordant prognostic prediction with FPS.\"\n",
