Abstract:
Objective To investigate the photo-protective mechanisms of hydroxychloroquine and epigallocatechin gallate (EGCG) on HaCaT cells damaged from UVB irradiation. Methods Subconfluent HaCaT cells were irradiated with different doses of UVB irradiation and treated with the above listed agents. The mRNA expression levels of p53, p21, c-fos and GADPH genes were evaluated by reverse transcription-polymerase chain reaction (RT-PCR). Results UVB irradiation induced mRNA expression of p53, p21 and c-fos in cultured HaCaT cells, which were alleviated by hydroxychloroquine and EGCG treatment in UVB irradiation group. Conclusions The photo-protective effects of hydroxychloroquine and EGCG on HaCaT cells by UVB irradiation might be related to inhibition of the expression of p53,p21 and c-fos genes.
