+      "!Series_summary\t\"Nearly 1% of babies are born with congenital heart disease (CHD) – many of whom will require heart surgery within the first few years of life. A detailed understanding of cardiac maturation can help to expand our knowledge on cardiac diseases that develop during gestation, identify age-appropriate drug therapies, and inform clinical care decisions related to surgical repair and postoperative management. Yet, to date, our knowledge of the temporal changes that cardiomyocytes undergo during postnatal development is limited. In this study, we collected right atrial tissue samples from pediatric patients (n=117) undergoing heart surgery. Patients were stratified into five age groups. We measured age-dependent adaptations in cardiac gene expression, and used computational modeling to simulate action potential and calcium transients. Enrichment of differentially expressed genes (DEGs) revealed age-dependent changes in several key biological processes (e.g., cell cycle, structural organization), cardiac ion channels, and calcium handling genes. Gene-associated changes in ionic currents exhibited age-dependent trends, with changes in calcium handling (INCX) and repolarization (IK1) most strongly associated with an age-dependent decrease in the action potential plateau potential and increase in triangulation, respectively. We observed a shift in repolarization reserve, with lower IKr expression in younger patients, a finding potentially tied to an increased amplitude of IKs that could be triggered by elevated sympathetic activation in pediatric patients. Collectively, this study provides valuable insights into age-dependent changes in human cardiac gene expression and electrophysiology, shedding light on molecular mechanisms underlying cardiac maturation and function throughout development.\"\n",

+      "!Series_title\t\"Development and validation of a spatially informed assay that resolves biomarker discordance and predicts treatment response in breast cancer.\"\n",
+      "!Series_summary\t\"Background: Breast cancer (BCa) is a heterogeneous disease requiring precise diagnostics to guide effective treatment. Current assays fail to adequately address the complex biology of BCa subtypes/risk groups and accurately predict responses to treatments like antibody-drug conjugates (ADCs). To address these limitations, we developed and validated a novel diagnostic, prognostic, and predictive tool, mFISHseq.\"\n",
+      "!Series_summary\t\"Methods: Our approach, mFISHseq, integrates multiplexed RNA fluorescent in situ hybridization with RNA-sequencing, guided by laser capture microdissection. This technique ensures tumor purity, allows unbiased profiling of whole transcriptome data, and explicitly quantifies intratumoral heterogeneity.\"\n",
+      "!Series_summary\t\"Results: In a retrospective cohort study involving 1,082 FFPE breast tumors, mFISHseq demonstrated high analytical validity with 93% accuracy compared to immunohistochemistry across training and test sets. Our consensus subtyping approach provided near-perfect concordance with other molecular classifiers (κ > 0.85) and reclassified 30% of samples into subtypes with distinct prognostic implications. Consensus risk groups mitigated misclassification of single samples and provided prognostic information about both early and late relapse. High risk patients had enriched innate and adaptive immune signatures, which predicted response to neoadjuvant immunotherapy. Furthermore, we identified patients responsive to ADCs, as evidenced by a 19-feature classifier for T-DM1 sensitivity, validated on the multicenter, phase II, prospective I-SPY2 trial. To demonstrate the clinical potential, we deployed mFISHseq as a research use only test on 48 patients, revealing insights into the efficacy of novel targeted therapies, such as CDK4/6 inhibitors, immune checkpoint inhibitors, and ADCs.\"\n",
+      "!Series_summary\t\"Conclusion: The mFISHseq method solves a long-standing challenge in the precise diagnosis and classification of BCa subtypes/prognostic risk groups, and allows accurate response prediction for patients, including those treated with immunotherapies and ADCs.\"\n",
+      "!Series_overall_design\t\"Out of a starting cohort of 1,082 breast samples, we excluded one sample for revoked informed consent, four samples for damaged FFPE blocks or sections rendering them unable to be processed, 63 samples because pathology review revealed benign/healthy tissue or DCIS/LCIS, and one sample had missing clinical data. This left a cohort of 1,013 breast tumors available for later analyses. The published 1,254 breast cancer samples are comprised of 1,014 patients with invasive breast cancer (1 sample has no clinical data), 99 subtype samples from patients who had an extra region of interest (ROI) collected by laser capture microdissection (LCM), 25 patients with in situ carcinoma (24 DCIS/1 LCIS), 24 no tumor tissues (i.e., tissues dissected from tumor specimens that contained only healthy, ductal aplasia, or other benign cells upon pathological review), 12 true healthy samples, 41 scroll samples used for the LCM vs. no LCM experiment, and 39 positive control samples. The Macherey Nagel NucleoSpin total RNA FFPE XS kit was used for RNA isolation. After RNA isolation, RNA quantity was measured using the Qubit RNA HS (High Sensitivity) Assay Kit with a Qubit 4 Fluorometer and RNA quality using the Agilent High Sensitivity RNA ScreenTape with an Agilent 4150 TapeStation. The DV200 value of the sample (i.e., the percentage of fragments more than 200 bases in length) was calculated as recommended by Illumina. Samples with DV200 values over 15% were considered viable samples for library preparation. We used the Takara SMARTer Stranded Total RNA-Seq Kit v3 - Pico Input Mammalian kit to prepare total RNA-SEQ libraries following the manufacturer's instructions. We included a single natural positive control sample in each library preparation batch and a synthetic spike-in control in each sample to control for batch library preparation effects. Following library preparation, the quantity and fragment size range of the library was assessed using both the Qubit dsDNA HS kit (Qubit 4 Fluorometer) and the Agilent High Sensitivity DNA ScreenTape kit (Agilent 4150 TapeStation). Successfully prepared libraries contained sufficient library to pool on an Illumina NovaSeq 6000 sequencing instrument and fragment range spanning 200 - 1,000 bp, with a local maximum of 250 - 350 bp. Depending on pool size, individual sequencing libraries were pooled and sequenced on an Illumina NovaSeq 6000 using SP, S1, S2, or S4 flow cells. Pooled libraries were spiked with 10% PhiX as recommended by both Illumina and Takara for low-complexity libraries sequenced on patterned flow cells. Paired-end sequencing (2 x 100 bp) was conducted to obtain approximately 100 million reads per sample.\"\n",

Two weeks before the FMT (baseline) as well as two and eight weeks after the FMT, the participants underwent a sigmoidoscopy, and biopsies were collected at a standardised location (20-25 cm from the anal verge at the crossing with the arteria iliaca communis) from an uncleansed sigmoid. In patients treated with allogenic FMT, predominantly immune response-related genes sets were induced, with the strongest response two weeks after FMT. In patients treated with autologous FMT, predominantly metabolism-related gene sets were affected.\"\n",

+      "!Series_overall_design\t\"All patients involved in this prospective cohort study were recruited from Istanbul University School of Medicine between August 2014 and August 2015. Three cohorts (fertile controls, patients with RPL and UI) were studied and 24 patients were included in each cohort. None of the patients has received a prior infertility treatment and were not under a current treatment. The first cohort comprised fertile control patients who presented to our gynecology department for well woman examinations. The inclusion criteria were regularly cycling women aged under 35 years with at least one live birth, no history of infertility/treatment, no previous miscarriages and no associated gynecologic (endometriosis, fibroids, active or history of pelvic inflammatory disease) or other medical comorbidities (hyperprolactinemia, thyroid disease etc). The remaining cohorts constituted patients who presented to our in vitro fertilization (IVF) unit. The second cohort included patients with RPL with no history of successful pregnancies. The inclusion criteria for this group were regularly cycling women aged under 35 years with at least two consecutive pregnancy losses of 20 weeks or less, normal follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), prolactin (PRL), and thyroid-stimulating hormone (TSH) levels at day 2-3, normal uterine cavity shape and size, and bilateral tubal patency observed on hysterosalpingogram, no mutations detected in Factor V (Leiden) and prothrombin gene analysis, normal antithrombin III, protein C and S activity, negative results for lupus anticoagulant evaluation, cardiolipin antibody (IgM and IgG), and beta2-glycoprotein antibody (IgM and IgG) and normal karyotype. Their partners have normal spermiogram results and normal karyotype. The third cohort was formed by women with UI at least of 18 months of duration. The inclusion criteria for this group were regularly cycling women aged under 35 years with normal FSH, LH, E2, PRL, and TSH levels at day 2-3, normal uterine cavity shape and size, and bilateral tubal patency observed on a hysterosalpingogram. Their partners have normal spermiogram results.\"\n",

+      "!Series_summary\t\"Endometriosis, an estrogen-dependent, progesterone-resistant, inflammatory disorder affects 10% of reproductive-age women. It is diagnosed and staged at surgery, resulting in an 11-year latency from symptom onset to diagnosis, underscoring the need for less invasive, less expensive approaches. Since the uterine lining (endometrium) in women with endometriosis has altered molecular profiles, we tested whether molecular classification of this tissue can distinguish and stage disease. We developed classifiers using genomic data from n=148 archived endometrial samples from women with endometriosis or without endometriosis (normal controls or with other common uterine/pelvic pathologies) across the menstrual cycle and evaluated their performance on independent sample sets.  Classifiers were trained separately on samples in specific hormonal milieu, using margin tree classification, and accuracies were scored on independent validation samples. Classification of samples from women with endometriosis or no endometriosis involved two binary decisions each based on expression of specific genes. These first distinguished presence or absence of uterine/pelvic pathology and then no endometriosis from endometriosis, with the latter further classified according to severity (minimal/mild or moderate/severe). Best performing classifiers identified endometriosis with 90-100% accuracy, were cycle phase-specific or independent, and utilized relatively few genes to determine disease and severity. Differential gene expression and pathway analyses revealed immune activation, altered steroid and thyroid hormone signaling/metabolism and growth factor signaling in endometrium of women with endometriosis. Similar findings were observed with other disorders versus controls. Thus, classifier analysis of genomic data from endometrium can detect and stage pelvic endometriosis with high accuracy, dependent or independent of hormonal milieu. We propose that limited classifier candidate-genes are of high value in developing diagnostics and identifying therapeutic targets. Discovery of endometrial molecular differences in the presence of endometriosis and other uterine/pelvic pathologies raises the broader biological question of their impact on the steroid hormone response and normal functions of this tissue.\"\n",

+      "!Series_summary\t\"Background & Aims:  Non-alcoholic steatohepatitis (NASH), a subtype of non-alcoholic fatty liver disease (NAFLD) that can lead to fibrosis, cirrhosis, and hepatocellular carcinoma, is characterized by hepatic inflammation.  Despite evolving therapies aimed to ameliorate inflammation in NASH, the transcriptional changes that lead to inflammation progression in NAFLD remain poorly understood.  The aim of this study is to define transcriptional changes in early, non-fibrotic NAFLD using a biopsy-proven non-fibrotic NAFLD cohort.  Methods:  We extracted RNA from liver tissue of 40 patients with biopsy-proven NAFLD based on NAFLD Activity Score (NAS) (23 with NAS ≤3, 17 with NAS ≥5) and 21 healthy controls and compared changes in expression of 594 genes involved in innate immune function.    Results:  Compared to healthy controls, NAFLD patients with NAS ≥5 had differential expression of 211 genes, while those with NAS ≤3 had differential expression of only 14 genes.  Notably, osteopontin (SPP1) (3.74-fold in NAS ≤3, 8.28-fold in NAS ≥5) and CXCL10 (2.27-fold in NAS ≤3, 8.28-fold in NAS ≥5) gene expression were significantly upregulated with histologic progression of NAFLD.\"\n",

+      "!Series_summary\t\"Early-onset Alzheimer’s disease-like pathology in Down syndrome (DS, trisomy 21) is commonly attributed to an increased dosage of the amyloid precursor protein (APP) gene.  To test this central tenet of the amyloid-cascade hypothesis we deleted the supernumerary copy of the APP gene in trisomic DS iPSC, or upregulated APP expression in euploid human pluripotent stem cell lines with dCas9-VP64, and subjected these lines to prolonged cortical neural differentiation. Our data reveal that increased APP gene dosage and expression is necessary and sufficient for increased beta-amyloid production and pyroglutamate(E3)-containing plaque deposition, but is neither sufficient nor required for tau hyperphosphorylation, neurofibrillary tangle formation, or increased oxidative stress-induced apoptosis in neurons. Transcriptome comparisons of the isogenic neurons demonstrates that the supernumerary APP gene copy has profound temporally-modulated genome-wide effects on gene expression during differentiation and maturation of DS neuronal cultures that link APP function to regulation of genes involved in neuronal synaptic function and outgrowth of neuronal processes. Collectively, our data reveal that APP plays an important role in the amyloidogenic aspects of Alzheimer’s disease, but challenge the hypothesis that increased APP levels are solely responsible for hyperphosphorylation of tau or enhanced oxidative stress-induced neuronal cell death in Down syndrome associated AD-pathogenesis.\"\n",

IBS is characterized by abdominal pain/discomfort associated with altered bowel function, such as diarrhea or constipation, without gross structural changes or inflammation [1]; IBD is characterized by gross inflammation in the gastrointestinal (GI) tract which can result in symptoms such as abdominal pain, cramping, diarrhea and bloody stools.  IBS and IBD can profoundly affect quality of life and are influenced by stress and resiliency.The impact of mind-body interventions (MBIs) on IBS and IBD patients has not previously been examined. In this study IBS and  IBD patients were enrolled in a 9-week relaxation response based mind-body group intervention (RR-MBI), focusing on elicitation of the RR and cognitive skill building. We performed Peripheral blood transcriptome analysis to identify genomic correlates of the RR-MBI.\"\n",

Total RNA was isolated from whole blood samples and gene expression profile was assessed on IBS and IBD patients with paired pre- and post-intervention samples using HT U133 Plus PM Array plates (Affymetrix, Santa Clara, CA).\"\n",

+      "!Series_summary\t\"Background: Renal cell carcinoma (RCC) is characterized by a number of diverse molecular aberrations that differ among individuals. Recent approaches to molecularly classify RCC were based on clinical, pathological as well as on single molecular parameters. As a consequence, gene expression patterns reflecting the sum of genetic aberrations in individual tumors may not have been recognized. In an attempt to uncover such molecular features in RCC, we used a novel, unbiased and integrative approach.\"\n",
+      "!Series_summary\t\"Methods: We integrated gene expression data from 97 primary RCCs of different pathologic parameters, 15 RCC metastases as well as 34 cancer cell lines for two-way nonsupervised hierarchical clustering using gene groups suggested by the PANTHER Classification System. We depicted the genomic landscape of the resulted tumor groups by means of Single Nuclear Polymorphism (SNP) technology. Finally, the achieved results were immunohistochemically analyzed using a tissue microarray (TMA) composed of 254 RCC. Results: We found robust, genome wide expression signatures, which split RCC into three distinct molecular subgroups. These groups remained stable even if randomly selected gene sets were clustered. Notably, the pattern obtained from RCC cell lines was clearly distinguishable from that of primary tumors. SNP array analysis demonstrated differing frequencies of chromosomal copy number alterations among RCC subgroups. TMA analysis with group-specific markers showed a prognostic significance of the different groups. Conclusion: We propose the existence of characteristic and histologically independent genome-wide expression outputs in RCC with potential biological and clinical relevance.\"\n",

Genomic DNA from renal cell was hybridized to renal cell carcinoma samples and matched normal kidney tissue biopsies, using the Affymetrix GenomewideSNP_6 platform.

+      "!Series_summary\t\"Background : Chromophobe renal cell carcinoma (chRCC) and renal oncocytoma are two distinct but closely related entities with strong morphologic and genetic similarities.  While chRCC is a malignant tumor, oncocytoma is usually regarded as a benign entity.  The overlapping characteristics are best explained by a common cellular origin, and the biologic differences between chRCC and oncocytoma are therefore of considerable interest in terms of carcinogenesis, diagnosis and clinical management. Previous studies have been relatively limited in terms of examining the differences between oncocytoma and chromophobe RCC.\"\n",
+      "!Series_summary\t\"Methods : Gene expression profiling using the Affymetrix HGU133Plus2 platform was applied on chRCC (n=15) and oncocytoma specimens (n=15).  Supervised analysis was applied to identify a discriminatory gene signature, as well as differentially expressed genes.  Immunohistochemical validation was performed in an independent set of tumors.\"\n",
+      "!Series_summary\t\"Results : A novel 14 probe-set signature was developed to classify the tumors internally with 93% accuracy, and this was successfully validated on an external data-set with 94% accuracy. Parafibromin, aquaporin 6, and synaptogyrin 3 were novel immunohistochemical markers effectively discriminating the two pathologic entities.\"\n",
+      "!Series_summary\t\"Conclusion : Gene expression profiles and pathway analysis effectively distinguish chRCC from oncocytoma. We have generated a novel transcript predictor that is able to discriminate between the two entities accurately, and which has been validated both in an internal and an independent data-set, implying generalizability. We have identified a series of immunohistochemical markers that are clinically useful in discriminating chRCC and oncocytoma.\"\n",

The main effect of FH mutation is fumarate accumulation. The current paradigm posits that the main consequence of fumarate accumulation is HIF-a stabilization. Paradoxically, FH mutation differs from other HIF-a stabilizing mutations, such as VHL and SDH mutations, in its associated tumor types. We identified that fumarate can directly up-regulate antioxidant response element (ARE)-controlled genes. We demonstrated that AKR1B10 is an ARE-controlled gene and is up-regulated upon FH knockdown as well as in FH-null cell lines. AKR1B10 overexpression is also a prominent feature in both hereditary and sporadic PRCC2. This phenotype better explains the similarities between hereditary and sporadic PRCC2.\"\n",

+      "!Series_summary\t\"Intronic and intergenic long noncoding RNAs (lncRNAs) are emerging gene expression regulators. The molecular pathogenesis of renal cell carcinoma (RCC) is still poorly understood, and in particular, limited studies are available for intronic lncRNAs expressed in RCC. Microarray experiments were performed with two different custom-designed arrays enriched with probes for lncRNAs mapping to intronic genomic regions. Samples from 18 primary clear cell RCC tumors and 11 nontumor adjacent matched tissues were analyzed with 4k-probes microarrays. Oligoarrays with 44k-probes were used to interrogate 17 RCC samples (14 clear cell, 2 papillary, 1 chromophobe subtypes) split into four pools. Meta-analyses were performed by taking the genomic coordinates of the RCC-expressed lncRNAs, and cross-referencing them with microarray expression data from three additional human tissues (normal liver, prostate tumor and kidney nontumor samples), and with large-scale public data for epigenetic regulatory marks and for evolutionarily conserved sequences. A signature of 29 intronic lncRNAs differentially expressed between RCC and nontumor samples was obtained (false discovery rate (FDR) <5%). An additional signature of 26 intronic lncRNAs significantly correlated with the RCC five-year patient survival outcome was identified (FDR <5%, p-value ≤0.01). We identified 4303 intronic antisense lncRNAs expressed in RCC, of which 25% were cis correlated (r >|0.6|) with the expression of the mRNA in the same locus across three human tissues. Gene Ontology (GO) analysis of those loci pointed to ‘regulation of biological processes’ as the main enriched category. A module map analysis of all expressed protein-coding genes in RCC that had a significant (r ≥|0.8|) trans correlation with the 20% most abundant lncRNAs identified 35 relevant (p <0.05) GO sets. In addition, we determined that 60% of these lncRNAs are evolutionarily conserved. At the genomic loci containing the intronic RCC-expressed lncRNAs, a strong association (p <0.001) was found between their transcription start sites and genomic marks such as CpG islands and histones methylation and acetylation. Intronic antisense lncRNAs are widely expressed in RCC tumors. Some of them are significantly altered in RCC in comparison with nontumor samples. The majority of these lncRNAs is evolutionarily conserved and possibly modulated by epigenetic modifications. Our data suggest that these RCC lncRNAs may contribute to the complex network of regulatory RNAs playing a role in renal cell malignant transformation.\"\n",
+      "!Series_overall_design\t\"A total of 22 human kidney tissue samples consisting of 11 primary renal tumors and 11 matched adjacent nontumor tissues from clear cell renal cell carcinmoa (RCC) patients were evaluated in this study. We compared the expression profiles of tumor and non-tumor samples obtained from patients with clear cell RCC to evaluate a possible correlation of the lncRNAs with renal malignancy. The set of clear cell RCC expression profiles was generated using a custom-designed cDNA microarray platform with 4,608 unique elements in replicate (9,216) enriched in gene fragments that map to intronic regions of known human genes (GPL3985).\"\n",

+      "!Series_summary\t\"Intronic and intergenic long noncoding RNAs (lncRNAs) are emerging gene expression regulators. The molecular pathogenesis of renal cell carcinoma (RCC) is still poorly understood, and in particular, limited studies are available for intronic lncRNAs expressed in RCC. Microarray experiments were performed with two different custom-designed arrays enriched with probes for lncRNAs mapping to intronic genomic regions. Samples from 18 primary clear cell RCC tumors and 11 nontumor adjacent matched tissues were analyzed with 4k-probes microarrays. Oligoarrays with 44k-probes were used to interrogate 17 RCC samples (14 clear cell, 2 papillary, 1 chromophobe subtypes) split into four pools. Meta-analyses were performed by taking the genomic coordinates of the RCC-expressed lncRNAs, and cross-referencing them with microarray expression data from three additional human tissues (normal liver, prostate tumor and kidney nontumor samples), and with large-scale public data for epigenetic regulatory marks and for evolutionarily conserved sequences. A signature of 29 intronic lncRNAs differentially expressed between RCC and nontumor samples was obtained (false discovery rate (FDR) <5%). An additional signature of 26 intronic lncRNAs significantly correlated with the RCC five-year patient survival outcome was identified (FDR <5%, p-value ≤0.01). We identified 4303 intronic antisense lncRNAs expressed in RCC, of which 25% were cis correlated (r >|0.6|) with the expression of the mRNA in the same locus across three human tissues. Gene Ontology (GO) analysis of those loci pointed to ‘regulation of biological processes’ as the main enriched category. A module map analysis of all expressed protein-coding genes in RCC that had a significant (r ≥|0.8|) trans correlation with the 20% most abundant lncRNAs identified 35 relevant (p <0.05) GO sets. In addition, we determined that 60% of these lncRNAs are evolutionarily conserved. At the genomic loci containing the intronic RCC-expressed lncRNAs, a strong association (p <0.001) was found between their transcription start sites and genomic marks such as CpG islands and histones methylation and acetylation. Intronic antisense lncRNAs are widely expressed in RCC tumors. Some of them are significantly altered in RCC in comparison with nontumor samples. The majority of these lncRNAs is evolutionarily conserved and possibly modulated by epigenetic modifications. Our data suggest that these RCC lncRNAs may contribute to the complex network of regulatory RNAs playing a role in renal cell malignant transformation.\"\n",
+      "!Series_overall_design\t\"A total of 16 human renal tumors from clear cell renal cell carcinoma (RCC) patients were evaluated in this study. We compared the expression profiles of tumor samples obtained from patients with clear cell RCC who died as a consequence of the disease versus those alive without disease (5-years follow-up) to evaluate a possible correlation of the lncRNAs with patient survival. The set of clear cell RCC expression profiles was generated using a custom-designed cDNA microarray platform with 4,608 unique elements in replicate (9,216) enriched in gene fragments that map to intronic regions of known human genes (GPL3985).\"\n",

+      "!Series_summary\t\"Intronic and intergenic long noncoding RNAs (lncRNAs) are emerging gene expression regulators. The molecular pathogenesis of renal cell carcinoma (RCC) is still poorly understood, and in particular, limited studies are available for intronic lncRNAs expressed in RCC. Microarray experiments were performed with two different custom-designed arrays enriched with probes for lncRNAs mapping to intronic genomic regions. Samples from 18 primary clear cell RCC tumors and 11 nontumor adjacent matched tissues were analyzed with 4k-probes microarrays. Oligoarrays with 44k-probes were used to interrogate 17 RCC samples (14 clear cell, 2 papillary, 1 chromophobe subtypes) split into four pools. Meta-analyses were performed by taking the genomic coordinates of the RCC-expressed lncRNAs, and cross-referencing them with microarray expression data from three additional human tissues (normal liver, prostate tumor and kidney nontumor samples), and with large-scale public data for epigenetic regulatory marks and for evolutionarily conserved sequences. A signature of 29 intronic lncRNAs differentially expressed between RCC and nontumor samples was obtained (false discovery rate (FDR) <5%). An additional signature of 26 intronic lncRNAs significantly correlated with the RCC five-year patient survival outcome was identified (FDR <5%, p-value ≤0.01). We identified 4303 intronic antisense lncRNAs expressed in RCC, of which 25% were cis correlated (r >|0.6|) with the expression of the mRNA in the same locus across three human tissues. Gene Ontology (GO) analysis of those loci pointed to ‘regulation of biological processes’ as the main enriched category. A module map analysis of all expressed protein-coding genes in RCC that had a significant (r ≥|0.8|) trans correlation with the 20% most abundant lncRNAs identified 35 relevant (p <0.05) GO sets. In addition, we determined that 60% of these lncRNAs are evolutionarily conserved. At the genomic loci containing the intronic RCC-expressed lncRNAs, a strong association (p <0.001) was found between their transcription start sites and genomic marks such as CpG islands and histones methylation and acetylation. Intronic antisense lncRNAs are widely expressed in RCC tumors. Some of them are significantly altered in RCC in comparison with nontumor samples. The majority of these lncRNAs is evolutionarily conserved and possibly modulated by epigenetic modifications. Our data suggest that these RCC lncRNAs may contribute to the complex network of regulatory RNAs playing a role in renal cell malignant transformation.\"\n",

Body weight increased significantly in the 12 weeks, both in the intervention group (+1.6 ± 0.2 kg, p<.0001) and in the standard care group (+1.8 ± 0.2 kg, p<.0001). Gait speed during 4m and 400m tests improved over time in the intervention group, whereas the standard care showed no improvements (time*treatment effects 400m: p=0.038 and 4m: p=0.048). Gene sets related to mitochondrial functioning were strongly upregulated in the participants receiving the intervention product. We showed that a novel oral nutritional supplement improves gait speed in older adults via improvements in mitochondrial functioning.\"\n",

Body weight increased significantly in the 12 weeks, both in the intervention group (+1.6 ± 0.2 kg, p<.0001) and in the standard care group (+1.8 ± 0.2 kg, p<.0001). Gait speed during 4m and 400m tests improved over time in the intervention group, whereas the standard care showed no improvements (time*treatment effects 400m: p=0.038 and 4m: p=0.048). Gene sets related to mitochondrial functioning were strongly upregulated in the participants receiving the intervention product. We showed that a novel oral nutritional supplement improves gait speed in older adults via improvements in mitochondrial functioning.\"\n",

+      "!Series_summary\t\"Axicabtagene ciloleucel (axi-cel), an anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved for treatment of relapsed/refractory large B-cell lymphoma (LBCL), has comparable efficacy across conventional LBCL markers. We analysed whether pre- and posttreatment  tumour immune contexture determines clinical outcomes for axi cel–treated patients in the ZUMA-1 pivotal study. Longitudinal evaluation of the tumour microenvironment (TME) uncovered dynamic patterns that occurred rapidly after axi-cel (within 2 weeks) in responders—pronounced enhancement of T- and myeloid cell signatures and diminution of B cell signature. Clinical response and overall survival associated with high CD8+ T-cell density (Immunoscore) and immune gene expression (Immunosign21) in TME pretreatment, which was paralleled by blood CAR T-cell levels posttreatment. High density of regulatory T cells in TME pretreatment associated with reduced axi-cel–related neurologic toxicity. At relapse, the TME evolved toward an immune-detrimental contexture with decreased T-cell–related and increased counterregulatory immune signatures and B cell lineage antigens. A TME rich in T-cell attractive chemokines (CCL5, CCL22), gamma-chain receptor cytokines (IL-15, IL-7, IL-21), and interferon regulated molecules associated with T-cell infiltration and markers of activity, a result validated in 2 independent datasets totalling ≈300 LBCL samples.\"\n",

We analysed whether pre- and posttreatment  tumour immune contexture determines clinical outcomes for axi cel��treated patients in the ZUMA-1 pivotal study. Longitudinal evaluation of the tumour microenvironment (TME) uncovered dynamic patterns that occurred rapidly after axi-cel (within 2 weeks) in responders—pronounced enhancement of T- and myeloid cell signatures and diminution of B cell signature. Clinical response and overall survival associated with high CD8+ T-cell density (Immunoscore) and immune gene expression (Immunosign21) in TME pretreatment, which was paralleled by blood CAR T-cell levels posttreatment. High density of regulatory T cells in TME pretreatment associated with reduced axi-cel–related neurologic toxicity. At relapse, the TME evolved toward an immune-detrimental contexture with decreased T-cell–related and increased counterregulatory immune signatures and B cell lineage antigens. A TME rich in T-cell attractive chemokines (CCL5, CCL22), gamma-chain receptor cytokines (IL-15, IL-7, IL-21), and interferon regulated molecules associated with T-cell infiltration and markers of activity, a result validated in 2 independent datasets totalling ≈300 LBCL samples.\"\n",

Advancements in spatial profiling technologies have unveiled the complex dynamics of the tumor microenvironment, a crucial factor in cancer progression and therapeutic response. Using spatial profiling, this study investigates the effects of the MET inhibitor tepotinib on the TME in a case of locally advanced NSCLC with a METex14 skipping alteration.  Methods: A patient with resectable stage IIIB NSCLC, unresponsive to neoadjuvant platinum-based doublet chemotherapy, received tepotinib following detection of a METex14 skipping alteration. Paired pre- and post-treatment biopsies were subjected to GeoMx Digital Spatial Profiling using the Cancer Transcriptome Atlas and immune-related protein panels to evaluate shifts in the tumor immune microenvironment (TIME).  Results: Tepotinib administration resulted in pathological downstaging to stage IA1, which allowed for a successful lobectomy and evidenced a significant pathological response. The TIME was transformed from an immunosuppressive to a more permissive state, with upregulation of antigen-presenting and pro-inflammatory immune cells. Moreover, a marked decrease in immune checkpoint molecules, including PD-L1, was noted. Spatial profiling identified discrete immune-enriched clusters, indicating the role of tepotinib in modulating immune cell trafficking and function.  Conclusions: Tepotinib appears to remodel the TIME in a patient with METex14 skipping NSCLC, possibly increasing responsiveness to immunotherapy. This case supports the integration of genetic profiling into the management of early and locally advanced NSCLC to guide personalized, targeted interventions. These findings highlight the need to further evaluate combinations of MET inhibitors and immunotherapies.\"\n",
