Several groups reported YAP overexpression promotes epithelial to mesenchymal transition (EMT) in cancer cell lines.39 Recently, the CDK7 inhibitor THZ1 was suggested to increase the stability of Snail protein in colorectal cancer cell lines,40 and THZ1 was thought to suppress TGFβ2‐mediated EMT in lens epithelial cells.41 MPM has three pathological subtypes, epithelial, sarcomatoid and biphasic. The gene discussed is SNAI1; the disease is cancer.
