Effects of arsenic on cell proliferation and its related gene expression in human epidermal keratinocyte
摘要
To study the effects of low concentration of arsenic (As2O3) on DNA synthesis and related transcription factor gene E2F1 expression in keratinocyte. Human epidermal keratinocyte (cell line HaCaT) cultured in vitro was used. After treatment with various concentrations of arsenic
DNA synthesis and E2F1 expression in HaCaT cells were detected by using3H-TdR method and RT-PCR. Arsenic caused a modest increase of keratinocyte DNA synthesis when the concentration reached the range within 0.5–16 nmol/L
but the amount of incorporated3H-TdR decreased and returned to baseline level when the concentration of arsenic increased to over 16 nmol/L. RT-PCR analysis showed the level of E2F1 mRNA was elevated in HaCaT cells with the increase of DNA synthesis. Arsenic of a certain concentration could increase DNA synthesis and enhance E2F1 expression in HaCaT cell line
which might be one of the pathological mechanisms of skin disease related to arsenic.
