MLF1IP promotes cells proliferation and apoptosis by regulating CyclinD1 in breast cancer.

ABSTRACT: Breast cancer is the most frequently diagnosed cancer and the leading causes of cancer death among females in worldwide. It is urgent to develop novel biomarkers to improve risk stratification and optimize therapy choice. In our previous study, we firstly found that MLF1IP was upregulated in breast cancer tissue compared with adjacent normal tissue and patients with high MLF1IP expression had significantly lower overall survival. However, the biological function and cellular mechanisms of MLF1IP in breast cancer is still need to be elucidated. Here, we further investigated the role of MLF1IP in breast cancer by in vivo experiments. Our results showed that the expression level of MLF1IP was associated with lymph nodes metastasis and tumor size in clinical characteristic features. By biological function experiment, we found MLF1IP is correlated with cell proliferation and apoptosis and arrest cell cycle G1 through regulating Cyclin D1. Taken together, our findings suggested that MLF1IP could contribute to the oncogenic potential of breast cancer. To the best of our knowledge, it was firstly reported that MLF1IP was involved in breast cancer. This study provided a potential new marker and a target for gene therapy in breast cancer treatment.
