The Haoqin-Huaban formula alleviates UVB-induced skin damage through HOXA11-AS-mediated stabilization of EZH2
In this study, we found that administration of HQHB inhibited, in a dose-dependent manner, UVB-induced skin damage by eliminating oxidative stress. HQHB was found to upregulate HOXA11-AS expression by activating HIF-1α. Furthermore, HOXA11-AS stabilized the EZH2 protein by inhibiting its ubiquitination and proteasomal degradation. Consequently, rescue assays demonstrated that HOXA11-AS promoted proliferation and inhibited apoptosis in HaCaT cells by reducing oxidative stress. Taken together, our results help to elucidate the function and regulatory mechanism of HQHB in reducing UVB-induced skin damage.PMID:35559404 | PMC:PMC9091108
