Identification of protein kinase C isoforms in rat mesenteric small arteries and their possible role in agonist-induced contraction.

abstract：RATIONALE:Activin receptor-like kinase-1 (ALK1) is an endothelial transforming growth factor β receptor involved in angiogenesis. ALK1 expression is high in the embryo vasculature, becoming less detectable in the quiescent endothelium of adult stages. However, ALK1 expression becomes rapidly increased after angiogenic ...
