Knockdown of PRDX2 sensitizes colon cancer cells to 5-FU by suppressing the PI3K/AKT signaling pathway
Key concepts
Scholarcy highlights
- Colorectal cancer is the fifth most common cancer in China and one of the leading causes of cancer-related deaths worldwide
- We showed that knocking down PRDX2 in vitro facilitates cell death and apoptosis in colon cancer cells treated with c 2017 The Author(s)
- These results demonstrate that the lentivirus-mediated shRNA targetted PRDX2 effectively and knocked down PRDX2 expression in colon cancer cells
- To determine the role of PRDX2 in colon cancer cells treated with 5-FU, we used the Cell Counting Kit-8 assay to detect the survival rate of colon cancer cells that were stably transfected with NC-shRNA-LV and PRDX2-shRNA-LV and treated with 5-FU at different concentrations for 48 h
- We observed a lower survival rate in the shPRDX2 group, compared with the shCont group. These results indicated that knocking down the expression of PRDX2 increased the chemosensitivity of colon cancer cells to 5-FU, in a dose-dependent manner
- We found that PRDX2 and p-AKT were strongly expressed in the cytoplasm of colon cancer cells, and were weakly expressed in normal colon mucosal tissues
- Our results demonstrate that inhibiting PRDX2 expression promotes 5-FU-induced apoptosis in colon cancer cells via the PI3K/AKT signal pathway
