GR-α + GR-β mRNA had a high diagnostic value for GC sensitivity and resistance in AM patients (area under the ROC curve = 0.881, sensitivity = 79.1%, specificity = 85.0%). GR-α and GR-β mRNA levels were independently correlated with GC sensitivity. GR-α and GR-β mRNA levels were correlated with the spinal function of AM patients after GC treatment. Overall, GR-α and GR-β mRNA levels in PBMCs of AM patients can assist in the identification of GC sensitivity and are correlated with GC efficacy.</p>\u0000 </section>\u0000 </div>","PeriodicalId":8085,"journal":{"name":"Annals of Human Genetics","volume":"86 5","pages":"268-277"},"PeriodicalIF":1.9,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40178381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
