Abstract

Breast cancer is a common malignancy that severely threatens women's mental health and lives. The paclitaxel-resistant breast cancer cells were established through a continuous stimulation with paclitaxel in a stepwise escalating concentration manner. The expression of MAP7 was detected by RT-P CR and western blot. The annexin V staining assay was used to measure the cell apoptosis ratio. The expression of cell invasive ability and apoptosis-related proteins was detected by western blot assay. The cellular motility was tested via transwell and wound healing assays. This study indicated that the MAP7 expression was upregulated in breast cancer cells and paclitaxel-resistant breast cancer cells. Moreover, downregulating MAP7 not only suppressed cell viability, motility and invasion, but also enhanced cellular apoptosis in paclitaxel-resistant breast cancer cells. In summary, this study investigated the effect of MAP7 protein on cell critical physiological function, which provided a novel potential target for treating paclitaxel-resistant breast cancer.
