Is epithelial to mesenchymal transition good?

EMT, and its reverse process, MET (mesenchymal-epithelial transition) are critical for development of many tissues and organs in the developing embryo, and numerous embryonic events such as gastrulation, neural crest formation, heart valve formation, secondary palate development, and myogenesis.

Is epithelial-mesenchymal transition real?

The epithelial-to-mesenchymal transition (EMT) occurs during normal embryonic development, tissue regeneration, organ fibrosis, and wound healing. It is a highly dynamic process, by which epithelial cells can convert into a mesenchymal phenotype.

What is meant by epithelial-mesenchymal transition?

An epithelial-mesenchymal transition (EMT) is a biologic process that allows a polarized epithelial cell, which normally interacts with basement membrane via its basal surface, to undergo multiple biochemical changes that enable it to assume a mesenchymal cell phenotype, which includes enhanced migratory capacity.

What induces epithelial-mesenchymal transition?

Matrix stiffness induces epithelial–mesenchymal transition and promotes chemoresistance in pancreatic cancer cells | Oncogenesis.

What is the main function of mesenchymal cells?

Mesenchymal stem cells (MSCs) are multipotent stem cells found in bone marrow that are important for making and repairing skeletal tissues, such as cartilage, bone and the fat found in bone marrow.

What is the mesenchymal–epithelial transition?

The reverse process, mesenchymal–epithelial transition (MET), can similarly generate epithelial cells. Transitions between epithelial and mesenchymal states are also critical for the induction of pluripotent stem cells from somatic cells.

How does epithelial or mesenchymal status affect OSKM-induced reprogramming?

Somatic cell reprogramming studies show that an epithelial or mesenchymal status of the cell at the beginning of induction affects iPSC generation. For example, pre-treatment of MEFs with the TGF-β receptor inhibitor RepSox reduces the efficiency of OSKM-induced reprogramming 121, 122.

Does miR-182 promote epithelial–mesenchymal transition?

Li, Y. et al. MiR-182 inhibits the epithelial to mesenchymal transition and metastasis of lung cancer cells by targeting the Met gene. Mol. Carcinog. 57, 125–136 (2018). Zhu, G. et al. PAK5-mediated E47 phosphorylation promotes epithelial–mesenchymal transition and metastasis of colon cancer.

How do epithelial–mesenchymal transition transcription factors activate carcinoma cells?

Activation of epithelial–mesenchymal transition (EMT) via ectopic induction of several EMT-inducing transcription factors (EMT-TFs) enables carcinoma cells to express several immunosuppressive and immunoevasive molecules that make them resistant to cytolytic attack by CD8 + T cells.
