RNA modification is an essential component of the epitranscriptome,regulating RNA metabolism and cellular *** types of RNA modifications have been identified to date;they include N^(6)-methyladenosine(m^(6)A),N^(1)-methyladenosine(m1A),5-methylcytosine(m5C),N^(7)-methylguanosine(m^(7)G),N^(6),2′-O-dimethyladenosine(m^(6)Am),N4-acetylcytidine(ac^(4)C),*** modifications,mediated by regulators including writers,erasers,and readers,are associated with carcinogenesis,tumor microenvironment,metabolic reprogramming,immunosuppression,immunotherapy,chemotherapy,etc.A novel perspective indicates that regulatory subunits and post-translational modifications(PTMs)are involved in the regulation of writer,eraser,and reader functions in mediating RNA modifications,tumorigenesis,and anticancer *** this review,we summarize the advances made in the knowledge of different RNA modifications(especially m^(6)A)and focus on RNA modification regulators with functions modulated by a series of factors in cancer,including regulatory subunits(proteins,noncoding RNA or peptides encoded by long noncoding RNA)and PTMs(acetylation,SUMOylation,lactylation,phosphorylation,etc.).We also delineate the relationship between RNA modification regulator functions and carcinogenesis or cancer ***,inhibitors that target RNA modification regulators for anticancer therapy and their synergistic effect combined with immunotherapy or chemotherapy are discussed.

Chinese Journal of Integrative Medicine 2024年第1期30卷 18-24页

作者： MA Hang-kun WANG Yi-ming GUO Man-ping LI Chen-fei LI Rui GAO Rui Emergency Department Xiyuan Hospital Affiliated to China Academy of Chinese Medical SciencesBeijing(100091)China National Medical Products Administration for Laboratory of clinical research and Evaluation of Traditional Chinese Medicine Beijing(100091)China National clinical research Center for Chinese Medicine Cardiology Beijing(100091)China Postdoctoral Workstation of Yabao Pharmaceutical Group Co. Ltd.YunchengShanxi Province(044602)China

Objective: To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application. Methods: Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching(PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain(within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events. Results: Of 7,699 enrolled participants, 6,693(86.9%) received acupoint application and 1,450(21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group(AG) and non-application group(NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG(P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG(logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41–1.63). The median age of effective cases was 4 years, mainly 3–6 years old(40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG(P<0.05). The commonly used acupoints for the effective cases were Tiantu(RN 22), Shenque(RN 8) and Dazhui(DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently(support 84.39%). A total of 1,324(17.2%) patients experienced AEs, and mainly occurred in the AG, with s
