Mir 200

Mir 200

Mir 200 in molecular biology is short RNA molecule. It functions to control the expression levels of other genes by cleaving and binding mRNAs. The mir 200 family contains Mir 141, mir 429 and mir 200a, mir 200b and 200c. there are increasing signs to advocate that mir 200 are involved in cancer metastasis. mir 200 is made of five members and its members are found in two groups. mir 429, mir 200a and mir 200b are located in human’s chromosome 1 and mir 141 and mir 200c are located on chromosome 12 in humans.

Mir 200 family members are exceedingly enriched in epithelial tissues. Mir 200 is not expressed in ordinary fibroblast which are of mesenchymal origin, while Mir 200 family is expressed in ordinary epithelial cells. Mir 200 family is believed to play and important role in suppressing tumor by inhibiting transition to epithelial mesenchymal, which is the initiative step of metastasis. Epithelial Mesenchymal Transition occurs as a result of embryonic development and have great similarities with cancer development. Epithelial Mesenchymal Transition make cells to lose grip and rise in motility. This occurs during the initial stages of metastasis as characterized by suppression of E-cadherin expression that happens during metastasis initial stages.

In a way of difference, Mir 200 has proven to have promoted metastasis last step in which migrating cancer cells experience Epithelial Mesenchymal Transition (MET) when distance tissues are colonizing. In a different stages of mouse mammary isogenic cancer cell lines, Mir 200 family have high expression in the cells which are able to form metastases but not in other cancer cells that are not able to colonize. Mir 200c Overexpression in metastatic cancer cells that are not ready enable Epithelial Mesenchymal Transition to colonize lung and live.

The function of Mir 200 family in lung start and development was categorized in recent years, but there were some arguments at the same time about their exact functional roles as appeared.

The Mir 200 is cost effective, safe moveable robot that can easily automates internal logistics in transportation. Mir 200 robot optimizes workflows and help to free works resources so one can increase productivity and reduce cost. This new generation of robot called Mir 200 is really changing the way businesses move their materials in their facilities. With the unusual flexibility and smartphones, Mir 200 can easily be used in almost any condition where the workers are spending time pushing cart. You can automate this job now so that the workers will have time to focus in other higher value activities.
