In some smooth muscles, the … WebJul 3, 2024 · The burst of cytosolic calcium can also activate the RBOHD, which induces a rapid increase in hydrogen peroxide (H 2 O 2) and triggers the ROS/redox signaling pathway, including MAPK-HSFs and MBF1c-HSFA3-DREB2A, during the heat stress response (HSR). MAPK-HSFs can regulate the expression of CAT, conversely controlling the level of ROS; …
WebMar 5, 2024 · The increase in cytosolic calcium ion concentration has various effects, one of which is to activate a protein kinase called protein kinase C (C for calcium), together with … WebThe source of the increase in cytosolic calcium levels can be extracellular or intracellular, or a combination of the two. In the case of tonic constriction of blood vessels, a constant supply of calcium comes from influx via the L-type calcium channels. The resting membrane potential of smooth muscle (between −50 and −40 mV) is such that ...
