WebNitric oxide signaling and S-nitrosylation. Nitric oxide (NO) produced by endothelial NO synthase (eNOS) mediates various cellular processes important for endothelial cell functions and regulates vascular response. In addition to conventional NO signaling via the activation of soluble guanylyl cyclase (sGC) to produce cGMP as a second messenger ... WebIt is thought that NO diffuses freely across cell membranes, but it may also permeate through low resistant membrane pathways. Here, we describe the participation of connexin (Cx)-formed channels in the NO transport across cell membranes and between …
