Expression of BRMS1 mRNA in human breast cancer and its clinical significance / 中国普通外科杂志

ABSTRACT

Objective To study the expression of BRMS1mRNA in human breast cancer tissues and their significance.Methods The expression of BRMS1mRNA was detected by reverse transcription-polymerase chain reaction(RT-PCR) in 71 breast cancer tissues and adjacent breast tissues,12 patients with benign breast tumors and 12 patients with normal breast tissue,and semi-quantitative analysis of band densities was also performed.Results The expression of BRMS1mRNA in 71 patients with breast cancer and adjacent breast tissue was 0.378?0.046 and 0.918?0.044,respectively;the expression of BRMS1mRNA in 12 patients with benign breast tumors and 12 patients with normal breast tissue was 0.908?0.047 and 0.934?0.028 respectively.BRMS1mRNA expression was significantly lower in breast cancer tissue compared to adjacent breast tissue,benign breast tumors and normal breast tissue(P0.05),but was related to axillary lymph node metastasis and clinical stage(P
