Changes in the expression of Bcl-2 and Fas in HL-60 cells treated with cyclosporine A / 中国病理生理杂志

AIM: To investigate the changes of the expression of Bcl-2 and Fas protein and the apoptosis in HL-60 cells induced by cyclosporine A. METHODS: The expression of Bcl-2 and Fas protein and apoptosis in (HL-60) cells were measured by immunohistochemistry analysis and flow cytometric analysis. RESULTS: There was strong expression of Bcl-2 in HL-60 cells, treatment with cyclosporine A (CsA) for 8-10 h down-regulated the expression of Bcl-2. Fas protein expression in HL-60 cells was very low, CsA induced apoptosis of HL-60 cells, but didn't induce Fas protein expression. CONCLUSION: CsA induces apoptosis in HL-60 cells by down-regulating Bcl-2 expression. [
