The ubiquitously expressed Na H exchanger , NHE 1 , acts downstream of RhoA in a pathway regulating focal adhesion and actin stress fiber formation . p160ROCK , a serine / threonine protein kinase , is a direct RhoA target mediating RhoA induced assembly of focal adhesions and stress fibers . ^^^ In CCL 39 cells , NHE 1 activity was stimulated by expression of mutationally active p160ROCK , but not by mutationally active protein kinase N , another RhoA target kinase . ^^^ Expression of a dominant interfering p160ROCK inhibited RhoA , but not Cdc 42 or Rac activation of NEH 1 . ^^^ In addition , the p160ROCK specific inhibitor Y 27632 inhibited increases in NHE 1 activity in response to RhoA , and to lysophosphatidic acid ( LPA ) , which stimulates RhoA , and it also inhibited LPA increased phosphorylation of NHE 1 . ^^^ |

RhoA activation was followed by p160ROCK activation mediated by RhoA , which led to myosin light chain ( MLC ) phosphorylation , which was dependent on RhoA and p160ROCK activities . ^^^ The kinetics of MLC activation was similar to that of RhoA and p160ROCK . ^^^ Inhibition of either RhoA or p160ROCK did not block SDF 1alpha induced short term actin polymerization , but induced the formation of long spikes arising from the cell body , which were found to be microtubule based . ^^^ |

TGF beta induced RhoA and p160ROCK activation is involved in the inhibition of Cdc25A with resultant cell cycle arrest . ^^^ In this article , we report that the absence of RhoA and p160ROCK activity in fibroblastic NIH 3T3 cells and its presence in epithelial NMuMG cells can at least partially explain the difference in the TGF beta growth response . ^^^ These data provide evidence that signaling through RhoA and p160ROCK is important in TGF beta inhibition of cell proliferation and links signaling components for epithelial transdifferentiation with regulation of cell cycle progression . . ^^^ |
