Objective:To study the expression and significance of TNF-transcription factor M1(FoxM1)in bladder cancer and cystitis glandularis(CG).Methods:A total of 30 patients with bladder cancer admitted to our hospital and received surgical treatment from February 2017 to February 2019 were included for the study.During surgery,bladder cancer tissues and normal bladder tissues(tissues more than 5cm away from the cancer tissue center)were collected.Meanwhile,we retained 30 CG tissues from 30 CG patients who received surgical treatment in our hospital at the same time.Bladder cancer cell lines RT4 and BIU87 were cultured and treated with TNF-αat different concentrations(0nM,1nM,5nM,10nM).The expressions of TNF-αand FoxM1 in different bladder tissues were analyzed,and the effects of different concentrations of TNF-αon the expressions of FoxM1 in bladder cancer cell lines and cyclin B1 and cyclin D1 in bladder cancer cell lines were analyzed.Results:The expression levels of TNF-αand FoxM1 in normal bladder,CG and bladder cancer tissues were gradually increased,and univariate analysis of variance showed that the differences between groups were statistically significant(all P<0.05).FoxM1 expression in bladder cancer cell lines treated with TNF-αat concentrations of 0nM,1nM,5nM and 10nM showed a gradual increase trend,and one-way anova showed that the difference between the groups was statistically significant(all P<0.05).After the treatment of bladder cancer cell lines with TNF-αat concentrations of 0nM,1nM,5nM and 10nM,the expression of cyclin B1 and cyclin D1 showed a gradually increasing trend,and one-way anova showed that the difference between groups was statistically significant(all P<0.05).Conclusion:TNF-αmay play a crucial role in the occurrence and development of CG by regulating the expression of transcription factor FoxM1,and then affecting the expression of cyclin B1 and cyclin D1,which is worthy of clinical attention.
