Abstract:
Objective To investigate the expression of breast cancer specific gene 1( BCSG1) in breast cancer tissues and its clinical significance.Methods The expression of BCSG1in 51cases of breast cancer tissues and 35 cases of adjacent tissues was determined by fluorescence quantitative polymerase chain reaction (FQ-PCR) and immunohistochenistry.Results FQ-PCR showed the expression level of BCSG1mRNA in breast cancer and adjacent tissues was 1.072 ± 0.178 and 0.324± 0.135 respectively.Immunohistochemistry showed the expression rate of BCSG1protein in breast cancer and adjacent tissues was 74.5％ (38/51) and 14.3％ (5/35).The expression of BCSG1mRNA and protein was dramatically increased in breast cancer tissues compared with that in normal background breast tissues (P ＜ 0.05).BCSG1mRNA and protein expression was significantly different in patients with lymph node metastasis and higher Nottingham prognostic index (P ＜ 0.05 ),and there was no significant difference with the pathological type of breast cancer,or status of ER,PR,and c-erbB2 ( P ＞ 0.05 ).Conclusions BCSG1is highly expressed in breast cancer tissues,which is closely related to the development and clinical prognosis of breast cancer.BCSG1is very likely to play an important role in the pathogenesis of breast cancer.
