Abstract

Background: The mitochondrial protein translocase of inner mitochondrial membrane 17 homolog A (TIMM17A) has been identified as a biomarker of breast cancer. The present study aimed to investigate the biological role of TIMM17A in human breast cancer cells. Materials and Methods: Anti-TIMM17A transgenes were stably transfected into MDA MB-231 and MCF-7 breast cancer cell lines. The impact of TIMM17A knock-down on cell migration and invasion were evaluated using the respective cell models. Results: Reducing the expression of TIMM17A in breast cancer cells resulted in reduction of cell migration using electric cell-substrate impedance sensing. It was also found that reduction of TIMM17A expression resulted in reduction of cell invasion compared to vector control. Conclusion: TIMM17A has a profound impact on the cellular function of breast cancer cells. A decrease of TIMM17A expression is associated with the reduction of the aggressiveness of breast cancer cells. TIMM17A, therefore, has potential in prognosis and treatment of breast cancer.
