The non-SMC condensin I complex subunit G (NCAPG) is a subunit of the condensin complex, many studies have shown that NCAPG is aberrantly expressed in different tumors and closely associated with poor prognosis, but its role in bladder cancer is unclear. In this paper, we found that NCAPG expression was upregulated in bladder cancer in tumor-related databases, and further verified the expression of NCAPG in bladder cancer tissues as well as bladder cancer cell lines by tissue microarray, qPCR, and WB. Next, we explored the changes in bladder cancer cell proliferation as well as migration after NCAPG knockdown by cell growth curve, colony formation, soft agar assay, and xenograft model. Finally, we examined the changes in downstream signaling pathways after NCAPG knockdown using RNA-Seq, and we found that the NF-κB signaling pathway was inhibited with NCAPG gene knockdown, which was verified by luciferase reporter assay as well as WB. In conclusion, our results illustrate that NCAPG knockdown can inhibit the proliferation of bladder cancer cells through the NF-κB signaling pathway. This finding demonstrates that NCAPG could be a potential target for the treatment of bladder cancer. •This article firstly studied the role of NCAPG in bladder cancer.•It is demonstrated that NCAPG promotes tumor proliferation in bladder cancer by activating the NF-κB signal pathway.•The role of NCAPG in bladder cancer was demonstrated by in vitro and in vivo experiments.
