| Research Abstract |
Endothelial-mesenchymal transition (EndMT) in which endothelial cells transdifferentiate into mesenchymal cells has been implicated in the malignant phenotypes of heart diseases and tumorigenesis in the human body. In this study, we elucidated the molecular mechanisms by which endothelial cells undergo EndMT. As a molecular mechanism for EndMT, we found that TGF-β, a representative EndMT-inducing cytokine, induces the expression of the mesenchymal marker Smooth Muscle Alpha-Actin through inducing the expression and the nuclear translocation of the transcription factor MRTF-A during EndMT in MS-1 endothelial cells.
