Abstract

Objective To investigate the effects of tacrolimus on the expression of SCF mRNA in keratinocytes and c-kit mRNA in melanoma cells.Methods Tacrolimus was used to treat cultured HaCaT keratinocytes and B16 melanoma cells for 48 hours.Subsequently,real-time fluorescence quantitative PCR was performed to determine the mRNA expression of SCF in HaCaT cells and of c-kit in B16 cells.Results A significant change was observed in the expression of SCF mRNA in HaCaT cells and c-kit mRNA in B16 cells treated with tacrolimus compared with untreated HaCaT cells and B16 cells,respectively (both P<0.05).Conclusion Tacrolimus can upregulate SCF mRNA expression in HaCaT cells and c-kit mRNA expression in R16 cells.
