Integrated machine learning and weighted gene co-expression network analysis reveals novel biomarkers in primary Sjögren syndrome
摘要
Abstract
Objective Primary Sjögren Syndrome(pSS)has complex etiology and pathogenesis,and there is currently a lack of efficient and specific diagnostic biomarkers.Methods This study integrated multiple machine learning algorithms with weighted gene co-expression network analysis to systematically identify poten-tial diagnostic biomarkers for pSS.Results The Endosome/lysosome-associated apoptosis and autophagy regu-lator 1(KIAA1324)was significantly downregulated in the pSS group.Pathway enrichment analysis indicated its primary involvement in the Epstein-Barr virus infection,Hepatitis B,and Janus Kinase-Signal Transducer and Activator of Transcription signaling pathway.Diagnostic efficacy evaluation confirmed that KIAA1324 exhib-its favorable accuracy and sensitivity in the diagnosis of pSS.Furthermore,the expression of KIAA1324 was closely correlated with the level of immune cell infiltration,showing a significant association with the infiltration of activated dendritic cells in particular.Conclusions The KIAA1324 is a potential biomarker for pSS.Its signifi-cant association with the infiltration of activated dendritic cells suggests that it may play a role in the regulation of the pSS immune microenvironment,providing new clues for elucidating its immunopathological mechanisms.关键词
