Objective: In order to explore RASSF1 A effectiveness in breast cancer,this experiment detects the expression of RASSF1 A DNA and protein before and after methyltransferases inhibitor( 5- Aza- CdR) used in breast cancer cell strain MCF- 7. Methods: Breast cancer cell lines MCF- 7 were treated with 5 and 10μmol /L 5- Aza-CdR,respectively. The expression of tumor suppressor gene RASSF1 DNA,protein was detected by methylation specificity PCR and Western blot. Results: RASSF1 A DNA and RASSF1 A protein were exp...
