In this study, we explored miR-203’s role in the chemoresistance of colon cancer. We found that overexpression of miR-203 significantly decreased cell proliferation and survival, and induced cell apoptosis in the p53-mutated colon cancer cells. Importantly, miR-203 overexpression increased the cytotoxic role of paclitaxel in the p53-mutated colon cancer cells, but not in the p53 wild-type cells. We...
Chemoresistance is a key cause of treatment failure in colon cancer. MiR-22 is a tumor-suppressing microRNA. To explore whether miR-22 is an important player in the development of chemoresistance in colon cancer, we overexpressed miR-22 and subsequently tested its role in cell proliferation, apoptosis, survival, and associated signaling in p53-mutated HT-29 and HCT-15 cells, and p53 wild-type HCT-116...
