Abstract
The pathogenesis of cystitis glandular (CG) is unclear, but it is generally considered to be a neoplastic lesion of urothelial hyperplasia formed by long-term chronic stimulation. There is growing evidence that circRNAs play important roles in a variety of cellular processes. However, there are few reports on the role and molecular mechanism of circRNA in CG. In the present study, we first isolated primary cells from CG tissues and adjacent normal tissues. Further experiments showed that CircTHBS1 was up-regulated in primary CG cells (pCGs). The results of CCK-8 showed that the overexpression of CircTHBS1 promoted the viability of pCGs, while the deletion of CircTHBS1 reduced the cell viability. Knocking out CircTHBS1 also inhibited the migration of pCGs. In addition, we demonstrated that CircTHBS1 played a role in the adsorption of miR-211 by “sponge” in pCG. In turn, miR-211 can directly target CYCLIN D2 (CCND2) 3′UTR to perform its function. Finally, we confirmed the role and mechanism of CircTHBS1/miR-211/CCND2 regulation axis in pCGs. In summary, our study is the first to reveal the role and underlying mechanism of CircTHBS1 in CG, providing a potential biomarker and therapeutic target for human CG.

Abstract
Our aim was to investigate differences in gene expression in bladder tissues between cystitis glandularis (CG) patients and healthy controls. Subsequent RNA was isolated from urinary bladder samples from CG patients and healthy controls, followed by RNA sequencing analysis. There were 4263 differentially expressed genes in urinary bladder between CG patients and controls, and 8 genes were verified with real-time PCR, Western blot, and enzyme-linked immunosorbent assay (ELISA) analysis. Gene set enrichment analysis (GSEA) revealed that 25 signaling pathways were upregulated in CG patients, and 17 signaling pathways were found upregulated in healthy controls. The mRNA expression levels of the indicated genes, including CCND1, CCNA1, EGFR, AR, CX3CL1, CXCL6, and CXCL1, were significantly increased in urinary bladder from CG and bladder cancer (BC) patients compared with healthy controls, while TP53 was decreased. CX3CL1, CXCL6, and CXCL1 concentrations in peripheral blood from CG and BC patients were significantly increased compared with healthy controls. The protein expression levels of CCND1, EGFR, and AR were significantly increased in urinary bladder from CG and BC patients compared with healthy controls. In conclusion, the gene expression profile of CG patients has established a foundation to study the gene mechanism of CG and BC progression.

Abstract
Bladder chronic inflammation is associated with the pathogenesis of bladder cancer; the underlying mechanism is unclear. The PT53 gene is an important anticancer gene in the body, which is suppressed in cancer. The ubiquitin E3 ligase A20 (A20) plays a role in regulating the activities of epithelial cells. This study was designed to investigate the correlation between A20 and the pathogenesis of bladder cancer. The biopsy tissues of human bladder cancer, bladder polypoid cystitis, and chronic inflammation were collected; the levels of A20 and p53 were analyzed by quantitative real-time RT-PCR, Western blotting, and immune precipitation. HEK293 cells were employed to test the role of overexpression of A20 in the suppression of the p53 gene in the cells. Fifty-six patients with bladder cancer, 48 patients with bladder polypoid cystitis, and 16 patients with bladder chronic inflammation were recruited into this study. Human bladder cancer tissue and the polypoid tissue showed high levels of A20, which had a positive correlation with the tumorigenesis in the bladder; 12 out of 46 (26.1%) patients with bladder polypoid cystitis were diagnosed as bladder cancer. A20 bound to p53 to form complexes in bladder cancer tissue and bladder polypoid tissue. The overexpression of A20 suppresses p53 protein levels in HEK293 cells. A20 has a positive correlation in the tumorigenesis of bladder polypoid disorders.
