Efficacy of a mixed extract of Salvia miltiorrhiza and Paeonia lactiflora in inhibiting the aging of vascular wall through in vitro and in vivo experiments

초록

Vascular wall aging has been strongly associated with cardiovascular diseases. Thus, this study aimed to investigate the efficacy of USCP-GVH-014, a mixed extract of Salvia miltiorrhiza Bunge and Paeonia lactiflora Pall., in inhibiting vascular wall aging through in vitro and in vivo experiments. The results revealed that USCP-GVH-014 inhibited abnormal cell proliferation, collagen overproduction, and MMP-2 and MMP-9 overexpression caused by various stimuli and recovered the antioxidant enzyme superoxide dismutase on human aortic smooth muscle cells. In addition, it inhibited the increase in ICAM-1 and VCAM-1 expression induced by tumor necrosis factor alpha on human aortic endothelial cells and prevented the aging of the vascular wall by regulating related proteins such as epidermal growth factor and interleukin-1ss. Furthermore, it reduced vascular aging in in vivo studies. These results demonstrate that USCP-GVH-014 effectively reduces vascular aging, thereby rendering it a potential therapeutic candidate for cardiovascular diseases. Graphical Abstract Mixed extract of Salvia miltiorrhiza and Paeonia lactiflora: inhibiting vascular wall aging via in vitro and in vivo studies.
