Involvement of BK α subunit tyrosine phosphorylation in vascular hyporesponsiveness of superior mesenteric artery following hemorrhagic shock in rats

Abstract

The tyrosine residues of BK(Ca) alpha subunit of SMA were phosphorylated following hemorrhagic shock, which was regulated by PTK and PTP and appeared to be related to the activation of BK(Ca) and the development of vascular hyporesponsiveness following hemorrhagic shock.
