| Summary: | Abstract Background Metabolic Associated Steatotic Liver Disease (MASLD), encompassing conditions simple liver steatosis (MAFL) and metabolic associated steatohepatitis (MASH), is the most prevalent chronic liver disease. Currently, the management of MASLD is impeded by the lack of reliable diagnostic biomarkers and effective therapeutic strategies. Methods We analyzed eight independent clinical MASLD datasets from the GEO database. Differential expression and weighted gene co-expression network analyses (WGCNA) were used to identify 23 genes related to inflammation. Five hub genes were selected using machine learning techniques (SVM-RFE, LASSO, and RandomForest) combined with a literature review. Nomograms were created to predict MASLD incidence, and the diagnostic potential of the hub genes was evaluated through receiver operating characteristic (ROC) curves. Additionally, Protein-Protein Interaction (PPI) networks, functional enrichment, and immune infiltration analyses were performed. Potential transcription factors and therapeutic agents were also explored. Finally, the expression and biological significance of these hub genes were validated using MASLD animal model, histological examination and transcriptomic profiles. Results We identified five hub genes—UBD/FAT10, STMN2, LYZ, DUSP8, and GPR88—that are potential biomarkers for MASLD. These genes exhibited strong diagnostic potential, either individually or in combination. Conclusion This study highlights five key biomarkers as promising candidates for understanding MASLD. These findings offer new insights into the disease’s pathophysiology and may contribute to the development of better diagnostic and therapeutic approaches. |
