Role of p38 mitogen-activated protein kinase in vascular endothelial aging: Interaction with Arginase-II and S6K1 signaling pathway


Figure 1. Comparison of inflammatory cytokines between young and senescent endothelial cells. Conditioned medium and cell lysate were collected from young (Y) and senescent (S) HUVECs which were serum-starved overnight. (A) SA-β-gal staining. (B) Immunoblotting to detect Arg-II, phsopho-p38-Thr180/Tyr182 (p-p38) and total-p38 (p38) in young and senescent cells. Tubulin served as loading control. (C) The secretion of IL-6 and IL-8 was evaluated by ELISA with collected conditioned medium described above. n=4, *p<0.05 vs young cells (Y).
