WebPhosphorylated CREB via cAMP/PKA pathway may also upregulate Bcl-2 expression and avoid oxidative stress-induced apoptosis, which is supposed to be mediated by GPER (Kanda and Watanabe, 2003). Transcriptional activation of c-fos occurs in the downstream of GPER-mediated EGFR/ERK1/2 pathway (Cirillo et al., 2024).

WebMay 29, 2003 · Fluid shear stress activates the Rho downstream effectors ROCK, LIM kinase (LIMK), and cofilin. The various negative mutants of RhoA, ROCK, LIMK, and cofilin can block the shear stress activation of SREBPs. The shear stress–activated SREBP depends on S2P proteases but not caspase-3. Stress fibers are contractile actin bundles found in non-muscle cells. They are composed of actin (microfilaments) and non-muscle myosin II (NMMII), and also contain various crosslinking proteins, such as α-actinin, to form a highly regulated actomyosin structure within non-muscle cells. Stress fibers have … See more Stress fibers are primarily composed of actin and myosin. Actin is a ~43kDa globular protein, and can polymerize to form long filamentous structures. These filaments are made of two strands of actin monomers (or … See more Stress fibers play the following roles in cellular functioning: 1. Adhesion Stress fibers are necessary for the formation and … See more As discussed above, Rho is responsible for the formation of stress fibers. Misregulation of the Rho family of GTPases is implicated in many diseases. Common clinical … See more The Rho family of GTPases regulate many aspects of actin cytoskeletal dynamics, including stress fiber formation.
