Study on survivin mRNA and protein of BEP-2D cells during its malignant transformation by cigarette smoke condensate / 重庆医科大学学报

ABSTRACT

Objective:To study the change of the survivin mRNA and protein of BEP-2D cells during its malignant transformation.Methods:Normal BEP-2D cell and BEP-2D cells treated by cigarette smoke condensate(CSC)for 15 weeks(P-15),25 weeks(P-25)and 38 weeks(P-38)were respectively chosen to study the survivin gene and protein by RT-PCR(retro-translation PCR,RT-PCR)and immunohistochemical method.Results:The survivin mRNA was found in BEP-2D cells of P-15,P-25 and P-38,respectively with 0.56,0.80,and 0.81,but not in the normal BEP-2D cell.The survivin protein was found in the normal BEP-2D cell,but not in BEP-2D cells of P-15,P-25 and P-38.The levels of survivin protein expressian were different between BEP-2D cells of P-15,P-25 and P-38 and normal BEP-2D cell,with significant difference between P-15 BEP-2D cell and normal BEP-2D cell(P
