摘      要:Objective:To evaluate the effects of curcumin on regulating the proliferation,cell cycle distribution,apoptosis and relevant mechanisms in keratinocyte cell ***:The human immortalized human keratinocyte lines(HaCaT cells) were treated with different doses of *** effects of curcumin on cell viability were measured by MTT assay,and the cell cycle distribution and apoptosis determined by flow *** mRNA expression changes of proliferating cell nuclear antigen(PCNA),cyclin D1 and Bcl-xL were from real-time PCR analysis and the protein levels were detected by Western ***:Data obtained in the study showed that curcumin could cause significantly inhibitory effect on proliferation in HaCaT cells in a time- and dose-dependent *** arrest at G1/S phase and significant apoptosis were observed after being treated with curcumin for 24 *** association with these,the expression of PCNA,cyclin D1 and Bcl-xL were decreased both at mRNA and protein levels for the same ***:Curcumin can inhibit proliferation,induce cell arrest at G1/S phase and cause apoptosis in HaCaT *** decreased expression of PCNA,cyclin D1 and Bcl-xL induced by curcumin contributes to the above effects in vitro.
