RNA 8-hydroxyguanosine Modification:New Insights into an Old Modification
Various types of RNA within cells play crucial roles in regulating cellular biological processes.RNA modifications are chemical modifications on substrate RNA with chemical groups.8-hydrox-yguanosine modification of RNA can impact the stability,structure and function of RNA.This modifica-tion enhances the diversity of RNA functions and roles.During oxidative stress,8-hydroxyguanine is a common and signature form of RNA chemical oxidative modification in cells.Both the structure and func-tion of RNA may be affected by 8-hydroxyguanine modification.The 8-hydroxyguanine modification of RNA has been demonstrated to impact both the structure and function of RNA through the induction of RNA strand breaks and base shedding.Research suggests that the presence of 8-hydroxyguanine modifi-cation in RNA may serve as a potential biomarker for disease progression.As interests in RNA modifica-tions grow,the 8-hydroxyguanine modification of RNA has garnered increasing attention.This article mainly reviews the mechanisms involved in the generation of 8-hydroxyguanine modification in RNA,its biological implications,and the proteins involved in regulating and repairing this modification,the detec-tion technology for 8-hydroxyguanine modified RNA,and the relationship between 8-hydroxyguanine mod-ification of RNA and various diseases,including neuropathic diseases and cancer.The primary objective is to offer a deeper understanding of the biological significance of RNA modification and the potential in-volvement of 8-hydroxyguanine modified RNA in disease pathogenesis.
