Objective:To test the relationship between the expression of Cyclin Dl and apoptosis in the ER (-) breast cancer cell line .Methods:Apoptosis was induced by1
25(OH)2D3in the ER(-)breast cell line.We compared the cell number by MTT
apoptotic cells by TUNEL
and the expression of Cyclin Dl by immunohistochemistry.Results:The expression of Cyclin DI was downregulated during apoptosis in MDA-MB-435s Cell line.It is a negative correlation between the apoptosis and the expression of Cyclin DI .Conclusion :Cylin DI reflected the effect of treatme nt in ER(-)breast cancer
