Abstract:
Objective To develop a real-time fluorescence quantitative PCR(FQ-RCR)method for detection of Kallkreins(KLK)4 gene expression in human breast cancer,and to investigate KLK4 expression levels in breast cancer and normal tissues.Methods KLK4 expression levels of 25 normal breast tissues and 39 cancer tissues were detected by the developed real-time quantitative PCR method.The statistical analysis for the relationship between KLK4 expression and several pathological parameters was performed by t test.Results The levels of KLK4 mRNA in normal breast and breast cancer tissue were 0.0120?0.0044 and 0.0272?0.0067 respectively(P0.05).Conclusions The level of KLK4 mRNA in breast cancer tissue was higher significantly than that in normal breast tissue.The results indicated that KLK4 gene expression may have relevance with breast cancer development but have no significant relevance with ER,PR,CerbB-2 and tumor metastasis.
