Background This study was conducted to investigate the exchange protein directly activated by c AMP ( E pac1), PDE 4, and PKC expression in breast cancer tissues, and the correlation between these proteins and AKAP 95, C x43, cyclin D 2, and cyclin E 1. Methods PV ‐9000 two‐step immunohistochemistry was used to analyze protein expression. Results The positive rate of E pac1 protein expression in breast cancer tissues (58%) was higher than in para‐carcinoma tissues (10%) ( P < 0.05). There were no significant differences in the positive rates of PDE 4 and PKC expression between breast cancer and para‐carcinoma tissues ( P > 0.05). The positive expression rate of PDE 4 was higher in the P 53 protein positive group compared to the P 53 negative group ( P < 0.05). Correlations between E pac1 and cyclin D 2, PDE 4 and cyclin D 2, AKAP 95 and PKC , C x43 and PKC, and cyclin D 2 and PKC proteins were observed ( P < 0.05). Conclusion E pac1 expression in breast cancer tissues was increased, suggesting that the protein may be involved in the development of breast cancer. Correlations between E pac1 and cyclin D 2, PDE 4 and cyclin D 2, AKAP 95 and PKC , C x43 and PKC , and cyclin D 2 and PKC proteins suggested synergistic effects among these proteins in the development of breast cancer.
