ABSTRACT
@# Objective：To analyze the expression and clinic significance of activity-dependent neuroprotective protein (ADNP) in bladder urothelial carcinoma. Methods: A total of 28 pairs of bladder cancer tissues and corresponding adjacent normal tissuesthat surgically resected at the Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University from June 1, 2019 to July 15, 2019 were collected for this study. The mRNAexpression ofADNP in 20 pairs of tissue samples was detected by qPCR, and the protein expressionin the other 8 pairs was detected by WB. Mean while, the clinicopathological data of patients with bladder urothelial carcinoma treated in our hospital from January 1, 2005 to December 31, 2007 were retrospectively analyzed; and the expression of ADNP in the corresponding paraffin tumor sections were determined with immunohistochemical staining, and normal bladder tissue sections from patients who underwent surgery for other bladder diseases during the same period were collected for comparison. Chi-square test was used to analyze the correlation between ADNP expression and different clinicopathological features, Kaplan-Meier method was used for survival analysis, and Cox risk regression model was used forunivariate and multivariate analysis of prognosticfactors. Results: ThetranscriptionalandtranslationallevelsofADNPincancertissues were higher than those in adjacent normal tissues (all P<0.05), and the expression level ofADNP was correlated with the histological grade, clinical stages and survival status of patients with bladder cancer (P<0.05). Of all the 221 patients included in the study, 32 patients lost to follow-up,and patients with high ADNP expression had
