A siRNA‐based method for efficient silencing of PYROXD1 gene expression in the colon cancer cell line HCT116
2019
PURPOSE: The aim of this study was to determine the biological function of pyridine nucleotide-disulfide oxidoreductase domain 1 (PYROXD1), a recently discovered protein, in colon cancer cell line HCT116. METHODS: The small interfering RNA (siRNA) was designed rationally on the basis of the target sequence against PYROXD1. Relative PYROXD1 mRNA levels were measured by a quantitative real-time polymerase chain reaction. Flow cytometry was performed to monitor tumor cells proliferation and apoptosis after siRNA transfection. RESULTS: Knockdown of PYROXD1 arrested the cell cycle, and induced late apoptosis in colon cancer cell line HCT116 DISCUSSION: Taken together, these results revealed the critical roles of PYROXD1 in regulating cell cycle and apoptosis and possibly will signify its therapeutic potential for targeting colorectal cancer models.
