Hyperglycemia contributes to the development and progression of bladder cancer. However, the underlying mechanism by which hyperglycemia promotes the aggressiveness of cancers, especially bladder cancer, is still incompletely understood. N6-methyladenosine (m6A) modification is a kind of methylation modification occurring at the N6 position of adenosine that is important for the pathogenesis of urological tumors. Recently, it was found that the m6A reader YTHDC1 is regulated by high-glucose conditions. In our study, we revealed that YTHDC1 is not only regulated by high-glucose conditions but is also downregulated in bladder cancer tissue and associated with the prognosis of cancer. We also showed that YTHDC1 suppresses the malignant progression of and the glycolytic process in bladder cancer cells in an\u003Cbr>m6A-dependent manner and determined that this effect is partially mediated by GLUT3 . Moreover, GLUT3 was found to destabilize YTHDC1 by upregulating RNF183 expression. In summary, we identified a novel YTHDC1/GLUT3/RNF183 feedback loop that regulates disease progression and glucose metabolism in bladder cancer.

Bladder cancer is the fifth most common cancer3, and nearly 170,000 patients die of this disease worldwide each year3–5. For muscle-invasive and advanced bladder cancer, platinumbased chemotherapy has been considered the standard systemic therapy over the past 40 years5. Due to the high mutation burden of bladder cancer, immunotherapy has been used to treat bladder cancer and has substantially improved the prognosis of patients in recent years6. However, studies exploring the molecular mechanism of advanced bladder cancer are also needed for the development of new therapeutic strategies.  \nAberrant glucose metabolism is one of the characteristics of malignant tumors7. In 1885, it was first reported that patients with cancer exhibited high blood glucose concentrations. Later, Warburg et al. noted that cancer tissues maintained a higher glucose utilization rate than normal tissues8. High blood glucose, or hyperglycemia, is usually caused by stress, diabetes mellitus, inflammation, or some kinds of drugs9–11. Among these causes, diabetes mellitus is the most common reason for long-term elevation of the plasma glucose concentration. Large cohort studies have demonstrated that diabetes mellitus-induced hyperglycemia is crucial for the tumorigenesis of solid tumors, such as  \nliver12, pancreatic13, and bladder14, 15 cancers. Lattermann et al. analyzed glucose metabolism in patients with bladder cancer. They found that the plasma concentration of glucose was elevated in patients with bladder cancer due to the lower rate of glucose clearance16. Moreover, it has been mentioned that hyperglycemia contributes to the development and progression of bladder cancer in diabetic patients. High glucose-mediated promotion of metastasis leads to death in patients with bladder cancer and diabetes17.
