PPARA and metabolic dysfunction-associated steatotic liver disease: In addition, the coexpressed genes were significantly enriched in 58 KEGG pathways, including oxidative phosphorylation, the citrate cycle (TCA cycle), fatty acid degradation, fatty acid elongation, fatty acid metabolism, nonalcoholic fatty liver disease (NAFLD), chemokines, and the peroxisome proliferators-activated receptor (PPAR) signaling pathway (Figure 4b and Table S6).
