Objective:To investigate the effect and possible mechanism of hydroxysafflor yellow A(HSYA) on human immortalized keratinocyte cell proliferation and ***:HaCaT cells were treated with *** proliferation was detected by the cell counting kit-8 assay,and cell migration was measured using wound healing assay and Transwell migration *** mRNA and protein expression levels of heparin-binding epidermal growth factor(EGF)-like growth factor(HBEGF),EGF receptor(EGFR),phosphatidylinositol 3-kinase(PI3K),protein kinase B(AKT),mammalian target of rapamycin(mTOR),and hypoxia-inducible factor-1α(HIF-1α) were detected by quantitative real-time polymerase chain reaction(qRT-PCR) and Western blot,***_0084443-overexpressing HaCaT cells and empty plasmid HaCaT cells were constructed using the lentiviral stable transfection and treated with *** expression of circ_0084443 was detected by ***:HSYA(800 μmol/L) significantly promoted HaCaT cell proliferation and migration(Pcirc_0084443 attenuated the mRNA expression levels of HBEGF,EGFR,PI3K,AKT,mTOR and HIF-1α(Pcirc_0084443 expression,further antagonized the inhibition of circ_0084443on HBEGF,EGFR,PI3K,AKT,m TOR and HIF-1α,and promoted the proliferation of circ_0084443-overexpressing HaCaT cells(Pcirc_0084443 on HaCaT cell migration(P>0.05).Conclusion:HSYA played an accelerative role in HaCaT cell proliferation and migration,which may be attributable to activating HBEGF/EGFR and PI3K/AKT signaling pathways,and had a particular inhibitory effect on the keratinocyte negative
