Research Abstract

Although the STAT3 activating cytokines play an important role in angiogenesis, little is known about the STAT3 role in skeletal muscle during ischemia-induced angiogenesis. STAT3 was promptly phosphorylated within skeletal muscle, and STAT3-activating cytokine including interleukin-6 and G-CSF were increased during hindlimb ischemia (HLI). Blood-flow recovery after HLI was impaired in skeletal muscle-specific, STAT3 knockout mice (sm-STAT3-KO). The number of CD31 positive cells after HLI was significantly less in sm-STAT3-KO than that in wild-type mice. Real-time PCR array analysis for angiogenesis revealed that the expression levels of angiogenic chemokines and inflammatory cytokines were significantly much lower in sm-STAT3-KO than those in wild-type mice after HLI. These results suggested that angiogenesis during ischemia was impaired in sm-STAT3-KO, possibly through the inhibition of angiogenic chemokines and inflammatory cytokines expression.
