Expression Of Hdac1 And Rbbp4 Correlate With Clinicopathologic Characteristics And Prognosis In Breast Cancer

Retinoblastoma binding protein 4 (RBBP4) plays an important role in transcription, cell cycle, and proliferation. Immunohistochemistry was performed to assess HDAC1 and RBBP4 expression in 240 BC patients. The expression of HDAC1 and RBBP4 in 12 pairs of BC tissues and their normal tissues was determined by western blotting. Kaplan-Meier analysis and Cox's proportional hazards regression were applied to evaluate the prognostic significance of HDAC1 and RBBP4. HDAC1 and RBBP4 expression in BC was significantly higher than that in normal tissues. HDAC1 was positively correlated with RBBP4 in breast cancer. HDAC1 and RBBP4 were negatively correlated with ER and PR in BC, respectively. The patients with high expression of RBBP4 had a worse overall survival time. The expression of RBBP4 was found to be significantly correlated with lymph node metastasis. RBBP4 may play a major role though HDAC1 in the development, metastasis, and prognosis of BC.
