Abstract
Although chemotherapy has significantly improved the prognosis of patients with cervical cancer, many patients exhibit selective responses to chemotherapy. This study aimed to identify genes associated with the sensitivity of cervical cancer cells to paclitaxel. SiHa cells were transfected with lentiCRISPR (genome-scale CRISPR knockout library v.2) and then treated with paclitaxel or vehicle for 14 days. Subsequently, we screened for candidate genes whose loss resulted in sensitivity to paclitaxel. We obtained 374 candidates, some of which were consistent with those reported in previous studies, including ABCC9, IL37, EIF3C, AKT1S1, and several members of the PPP gene family (PPP1R7, PPP2R5B, PPP1R7, and PPP1R11). Importantly, our findings highlighted the newly identified genes that could provide novel insights into the mechanisms of paclitaxel sensitivity in cervical cancer. Cas9 technology provides a reliable method for the exploration of more effective combination chemotherapies for patients at the gene level.
