Regulation of RGS2 and second messenger signaling in vascular smooth muscle cells by cGMP-dependent protein kinase.
RGS2, a GTPase-activating protein (GAP) for G(q)alpha, regulates vascular relaxation and blood pressure. RGS2 can be phosphorylated by type Ialpha cGMP-dependent protein kinase (cGKIalpha), increasing its GAP activity. To understand how RGS2 and cGKIalpha regulate vascular smooth muscle signaling and function, we identified signaling pathways that are controlled by cGMP in an RGS2-dependent man...
متن کاملRegulation of insulin-like growth factor I messenger RNA levels in vascular smooth muscle cells.
We have previously demonstrated specific insulin-like growth factor I (IGF I) messenger RNA (mRNA) transcripts in cultured rat aortic smooth muscle cells (RASM). To define the role of IGF I in the autocrine growth program of vascular smooth muscle cells, we quantitated IGF I mRNA levels in proliferating and quiescent (serum-deprived for 48 hours) RASM. IGF I mRNA levels were markedly decreased ...
متن کاملSpecific regulation of RGS2 messenger RNA by angiotensin II in cultured vascular smooth muscle cells.
The effects of angiotensin II (Ang II) are mediated primarily by Ang II type 1 receptors, which in turn are coupled to heterotrimeric G proteins. After receptor activation, the G(alpha) and G(betagamma) subunits dissociate, contributing to the signaling cascades involving protein kinase C (PKC) activation. Regulators of G protein signaling (RGS proteins) comprise a class of proteins that have b...
متن کاملanalysis of alterations in morphologic characteristics of mesenchymal stem cells by mechanical stimulation during differentiation into smooth muscle cells
background: mesenchymal stem cells (mscs) can be expanded and differentiated into many mature cell types including smooth muscle cells (smcs). in addition to growth factor, cyclic stretch contributes to differentiation of stem cells. mechanical stimuli are critical to morphological changes, development, regeneration, differentiation and pathology of mesenchymal tissues. the aim of this study is...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
