Unlike congenital abnormalities of oxysterol-metabolizing enzymes, such as cerebrotendinous xanthomatosis and hereditary spastic paraplegia type 5, it is often difficult to assess whether altered oxysterol levels in acquired diseases are the cause or the consequence of disease. In addition, oxysterols exert beneficial or deleterious effects on diseases depending on their structures. Despite these limitations, accumulated experimental evidence is beginning to clarify the impact of oxysterols on the pathophysiology of various diseases.</div></div>","PeriodicalId":52218,"journal":{"name":"Current Opinion in Endocrine and Metabolic Research","volume":"40 ","pages":"Article 100583"},"PeriodicalIF":0.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144632096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we provide an overview that supports this notion and bring insights into the intricate involvement of AT-derived miRNAs in the pathogenesis of cardiometabolic diseases, discussing some of their far-reaching effects on the liver, heart, vasculature, and other tissues. Moreover, we outline future research directions addressing current gaps in the field which we hope will further advance our comprehension of the role of AT-derived miRNAs.</div></div>","PeriodicalId":52218,"journal":{"name":"Current Opinion in Endocrine and Metabolic Research","volume":"38 ","pages":"Article 100572"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143378591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
