  • Such treatment was associated with upregulation of invasion- and inflammation-promoting soluble factors, such as matrix metalloproteinase 2 (MMP2), its activator MMP14, tissue inhibitors of matrix metalloproteinase 2 (TIMP2), chemokine ligand 2 (CCL2), and urokinase-type plasminogen activator (uPA), the latter two being linked to the recruitment of the monocytic cells.

  • Removal of ring culture system induces collective cell migration at the iPSC colony edge. (biomedcentral.com)
  • Whereas the formation of focal adhesions requires actomyosin-mediated contractile force mediated by RhoA , podosome formation is stimulated by a local loss of contractility and the recruitment of negative regulators of RhoA, such as p190RhoGAP [16] . (cellmigration.org)
  • We found that Tyr31/118-phosphorylated paxillin competes with p190RhoGAP for binding to p120RasGAP, and provides evidence that p190RhoGAP freed from p120RasGAP efficiently suppresses RhoA activity during cell adhesion. (silverchair.com)
