Research Abstract

Progression of cancer is induced by cancer associated fibroblasts (CAF). Recent reports have indicated that CAF is derived from tumor endothelial cells through endothelial-to-mesenchymal transition (EndMT). In the present study, we studied the molecular mechanisms underlying EndMT. Using MS-1 endothelial cells, I have found that activation of MRTF-A transcription factor by Rho signals is necessary for TGF-β-induced EndMT. I also found that BMP-9 and FGF enhanced and suppressed the TGF-β-induced EndMT. These results suggest that signaling cascades mediated by multiple cytokines modulate the TGF-β-induced EndMT.
