Using Machine Learning and Multi-Omics to Find Key Genes and Processes in Mitochondrial Recycling Linked to Non-Alcoholic Fatty Liver Disease

AI simplified

Abstract

Five key genes—IGF1, MYH11, HYOU1, SPATA18, and SCD—showed excellent disease discrimination in Non-alcoholic fatty liver disease (NAFLD) with a training set of 0.974.

  • These genes are significantly enriched in processes related to endoplasmic reticulum stress, , and lipid metabolism.
  • In the immune microenvironment of NAFLD, they are associated with increased macrophage M2 polarization and T cell infiltration.
  • Expression heterogeneity of these genes was observed across hepatocytes, macrophages, and T cells.
  • The study highlights a connection between mitochondrial dysfunction and inflammatory responses in NAFLD.
  • Experimental validation indicated altered core gene expression and mitophagy levels in NAFLD cell models.
