Volume-regulated outwardly rectifying anion channel (VRAC) plays an important role in cell-volume regulation in many types of cells. Little is known about the regulation of VRAC by phosphatidylinositides (PIs), which include phosphatidylinositol 3,4,5-trisphosphate (PIP3) and phosphatidylinositol 4,5-bisphosphate (PIP2). We examined the effect of PIs on the(More)
Sympathetic nerves regulate vascular tone by releasing neurotransmitters into the vasculature. We previously demonstrated that bradykinin facilitates sympathetic neurotransmission in rat mesenteric arteries. Although little is known about the intracellular mechanism modulating this neurotransmission, recent cell line experiments have shown that the KCNQ(More)
