Angiogenesis of protein kinase D1 in bone marrow-derived endothelial progenitor cells of rats / 中国药理学通报

ABSTRACT

Aim To explore the effect of protein kinase D1 (PKD1 )on adherence,migration,proliferation, microvascular formation,and eNOS expression in bone marrow-derived endothelial progenitor cells(EPCs)of rats.Method The EPCs were isolated from bone marrow of rats,cultured and detected,the effects of PKD1 and its specific blocking agent CID755673 on adhesion,migration,proliferation,or microvascular formation were observed,as well as mRNA and protein expression of endothelial nitric oxide synthase (eNOS ) in EPCs.Results PKD1 significantly promoted adhe-sion,migration,proliferation and microvascular forma-tion of EPCs,and upregulated the mRNA and protein expression of eNOS in EPCs,according to the cell cul-ture experiments of EPCs in vitro.Conclusion PKD1 has the role of angiogenesis through regulation of EPCs,which might be dependent on eNOS.
