Here, we identify a new role of YAP in the regulation of vascular senescence. The inhibition or deficiency and overexpression of YAP were performed in human umbilical vein endothelial cells (HUVECs) and isolated vascular tissues. Cellular and vascular senescence was assessed by analysis of the senescence-associated β-galactosidase (SA-β-gal) and expression of senescence markers P16, P21, P53, TERT and TRF1. We found that YAP was highly expressed in old vascular tissues, inhibition and knockdown of YAP decreased senescence, while overexpression of YAP increased the senescence in both HUVECs and vascular tissues. In addition, autophagic flux blockage and mTOR pathway activation were observed during YAP-induced HUVECs and vascular senescence, which could be relieved by the inhibition and knockdown of YAP. Moreover, YAP-promoted cellular and vascular senescence could be relieved by mTOR inhibition. Collectively, our findings indicate that YAP may serve as a potential therapeutic target for ageing-associated cardiovascular disease.Several therapeutic approaches have been described for their treatment of hypertrophic scars and keloids, but to date, the optimal treatment has not been established yet. Our in vivo study was conducted to evaluate the effect of a medical device consisting in an adhesive patch containing onion extract (Allium cepa) 10%, allantoin 1%, and pentaglycan 4% (Kaloidon patch) on hypertrophic scars and keloids. Thirty-nine patients with hypertrophic scars and seven patients with keloids were asked to apply an adhesive patch containing Allium cepa, allantoin, and pentaglycan once/day for at least 8 h consecutively, for 24 weeks. Patients were reevaluated 6 weeks (T6), 12 weeks (T12), and 24 weeks (T24) after starting the treatment through P
