This study was designed to explore the role of KAT3B, functioning as a succinylase, in the context of prostate cancer (PCa) .  \nMethods The expression levels were assessed using quantitative real-time PCR, Western blot, and immunofluorescence staining. To investigate protein-protein interactions, immunoprecipitation assays were performed. The interaction between proteins were confirmed by Co-immunoprecipitation assay. The cell phenotype of PCa cells was analyzed by CCK-8, flow cytometry, and transwell assays.  \nResults We found that KAT3B was over-expressed in PCa tumor tissues and cells. Downregulated KAT3B decreased the viability, migration, and invasion while accelerating the apoptosis of PCa cells. Mechanistically, KAT3B mediated the succinylation of c-Myc, meantime promoted the stability of c-Myc. c-Myc overexpression reversed the role of KAT3B in PCa cells. The in vivo study verified that KAT3B silencing inhibited the growth of PCa cancer tissues. Conclusion Our research indicates that KAT3B was highly expressed in PCa. KAT3B silencing inhibited PCa cell growth and cancer tissues growth by decreasing the succinylation and expression of c-Myc. These findings potentially contribute to novel approaches in diagnosing and treating PCa.  \nKeywords Prostate cancer, KAT3B, C-Myc, Succinylation  \nIntroduction  \nProstate cancer (PCa) is a malignant tumor occurring in the prostate. The disease tends to occur in older men over the age of 65 [1]. Recently, there has been a notable rise in the diagnosis of PCa among men younger than 55 years of age. The incidence of PCa varies greatly by race,  \n*Correspondence: Quanwei Fu [fuqw@163.com](fuqw@163.com)  \n1PET-CT Center, Citic Huizhou Hospital, Huizhou, China 2Department of Urology, Citic Huizhou Hospital, Huizhou, China 3Medical Office, Citic Huizhou Hospital, Zhongkai Avenue, Huicheng District, Huizhou, Guangdong Province 516006, China  \nfamilial inheritance, and geographical location [2]. Localized PCa is asymptomatic; however, once symptoms appear, PCa is usually too advanced and incurable. Thus, early screening is particularly important [3]. Moreover, over 10% of patients are diagnosed with the high-risk type, which can develop a fatal phenotype that requires earlier diagnosis and personalized treatment [4]. Surgery and radiotherapy are the first choices for the treatment of localized PCa [5]. Radical prostatectomy contributes to reducing mortality and improving survival rates [6]. Currently, although multiple biomarkers have been identified to be linked to PCa pathogenesis and have been proposed for treatment [7], the clinical effects of these targets are  \n© The Author(s) 2025.
