WebUsing inhibitor and dominant-negative constructs, we demonstrated that phosphatidylinositol 3-kinase (PI3K) was a key downstream effector of R-Ras in this pathway. Conclusions—OxPAPC, POVPC, and PEIPC induce a cAMP/R-Ras/PI3K signaling pathway that contributes to monocyte/endothelial cell adhesion and potentially … WebNational Center for Biotechnology Information
WebFeb 26, 2024 · Promotion of TH17 responses via THSB1 and ITGB1 is cAMP/PKA-dependent. Purified CD14 + monocytes were left untreated or treated for 16 h with CT with and without the PKA inhibitor H-89 (A,B) or ... WebMay 20, 2024 · This EGCG→cAMP→PKA→PP2A→MP activation pathway plays important roles in sensitizing melanoma and leukemic cells to anticancer drugs and in differentiating THP-1 monocytes to macrophages . It remains to be examined if the above EGCG-induced phosphatase activatory pathways may also mediate the adipogenic differentiation of MSCs.
WebcAMP on monocyte/macrophage differentiation are not as well understood. We show here that during differentiation, cAMP agonists can cause a large increase in the mRNA and protein levels of several of the pro-inflammatory CXCL and CCL chemokines. The cAMP mediator-exchange protein activated by cAMP (Epac) con- WebApr 1, 2014 · Likewise, in the macrophage cell line RAW264.7, TGR5 activation inhibited NF-κB activation via the cAMP signalling pathway [37]. When TGR5 was activated or overexpressed, NF-κB transcriptional activity was inhibited after LPS treatment, and was reversed in the presence of cAMP inhibitors [37].
WebApr 16, 2011 · In contrast, various agents, including adrenaline and noradrenaline, that are known to increase cAMP levels in endothelial cells promote adhesion of monocytes and leucocytes [29–31]. In agreement with the latter findings, we found that stimulation of cAMP by adrenaline was critical for increased expression of E-selectin, Icam1 and Vcam1 in ...
