Abstract Circular RNAs (circRNAs) have been extensively studied in tumor development and treatment. CircZNF609 has been shown to act as an oncogene in a variety of solid tumors and may serve as a novel biomarker for tumor diagnosis and treatment. However, the underlying role and mechanism of circZNF609 in bladder cancer (BCa) development and cisplatin chemosensitivity were unknown. Quantitative real-time PCR (qRT-PCR) was applied to determine the expression of circZNF609, microRNA 1200 (miR-1200) and CDC25B in BCa cells and tissues. Western blot was used to detect the protein level of CDC25B. Functional assays in vitro and in vivo were conducted to investigate the effects of circZNF609 on tumor development and cisplatin chemosensitivity in BCa. RNA sequencing and online databases were used to predict the interactions among circZNF609, miR-1200 and CDC25B. Dual luciferase reporter assay, RNA pull-down assay and RNA fluorescence in situ hybridization (FISH) were applied to confirm the mechanism. CircZNF609 expression was significantly up-regulated in BCa cell lines and tissues. Increased expression of circZNF609 was related to a worse survival in BCa patients. In vitro and in vivo, enforced-expression of circZNF609 enhanced BCa cells proliferation, migration and cisplatin chemoresistance. Mechanistically, circZNF609 alleviated the inhibition effect on target CDC25B expression by sponging miR-1200. CircZNF609 promoted tumor growth through novel circZNF609/miR-1200/CDC25B axis, implying that circZNF609 has significant potential to serve as a new diagnostic biomarker and therapeutic target for BCa patients.

Bladder cancer is the 10th most commonly diagnosed cancer worldwide. Although the incidence in men is 4 times higher than that in women, the diagnoses are worse for women. Over the past 30 years, the treatment for bladder cancer has not achieved a significant positive effect, and the outlook for mortality rates due to muscle-invasive bladder cancer and metastatic disease is not optimistic. Phytochemicals found in plants and their derivatives present promising possibilities for cancer therapy with improved treatment effects and reduced toxicity. In this study, we summarize the promising natural products of plant origin with anti-bladder cancer potential, and their anticancer mechanisms—especially apoptotic induction—are discussed. With the developments in immunotherapy, small-molecule targeted immunotherapy has been promoted as a satisfactory approach, and the discovery of novel small molecules against immune targets for bladder cancer treatment from products of plant origin represents a promising avenue of research. It is our hope that this could pave the way for new ideas in the fields of oncology, immunology, phytochemistry, and cell biology, utilizing natural products of plant origin as promising drugs for bladder cancer treatment.
