Aim: To determine the features of miR-122 and -200b expression signature in BC patients due to major clinical-pathological characteristics of the disease. Methodology: The expression levels of miR-122 and -200b and ER, PR, Her2/neu, Ki-67, E-cadh, N-cadh, FTH1, Hepc were analyzed in cancer tissue and sera of BC patients. Relative expression levels of the miR-122 and -200b were examined using qRT-PCR (Quantitative Reverse Transcription PCR), protein expression was measured by immunohistochemical analysis. Results: Correlation between miR-122 and -200b expression clinical-pathological characteristics of BC was established. Prognostic value of miR-122 and -200b was estimated. Discussion and Conclusion: Changes of miR-122 and -200b expression in tumor tissue and sera of BC patients provide information about major clinical-pathological characteristics of BC.
