Objective.
To verify and evaluate the value of CD40 as a noninvasive biomarker of cisplatin-resistant bladder cancer, we studied the expression of CD40 and the correlation between nucleophosmin (NPM1) and CD40 in cisplatin-resistant bladder cancer.
Methods.
Three cisplatin-resistant bladder cancer cell lines (T24/0.8DDP, BIU87/0.3DDP, and PUMC-91/0.6DDP) were studied, and lentivirus was used to silence NPM1 expression.
The expression of CD40 and NPM1 in three NPM1 silencing bladder cancer cell lines were detected by fluorescence microscopy and Western Blot.
The effects and proteomic bioinformatics of NPM1 gene knockout on cisplatin-resistant bladder cancer cells were analyzed by liquid chromatography-mass spectrometry (LC-MS) and gene ontology analysis (GO analysis).
Results.
The NPM1 gene was successfully silenced in three drug-resistant bladder cancer cell lines by lentivirus infection.
The knockdown efficiency was 70%.
After NPM1 gene knockout, 492 differential proteins were detected by LC-MS, whose fold change was more than 1.5 p<0.05.
A total of 57022 peptides, 54347 unique peptides, and 6686 protein groups were identified in all proteins of the tested cells (FDR < 0.01).
Hierarchical clustering and principal component analysis showed that 264 functional proteins were downregulated and 228 functional proteins were upregulated in the gene silencing group compared with those of the negative controls.
By GO analysis, the proteins affected by NPM1 cover a large number of proteins with biological functions, which may play an important role in the development of tumor in 492 differential proteins.
The CD40 was the most significantly downregulated protein after NPM1 silencing, with a difference of 2.6-fold change in abundance.
Conclusions.
There is a positive correlation between CD40 protein and NPM1 protein in drug-resistant bladder cancer.
Because NPM1 can reflect the characteristics of bladder cancer, CD40 may be a more sensitive marker for monitoring the prognosis of bladder cancer.
