PPARA and hepatocellular carcinoma: Figure S3 shows the top 20 cluster-related DEGs in HCC tissues. The m6A/m1A/m5C regulated gene subsets related DEGs were found to be involved in signaling release, neurotransmitter transport, drug catabolic process, positive regulation of protein secretion, regulation of secretion, calcium ion regulated exocytosis, hormone transport, regulation of protein secretion, and others using GO analysis (Figures 3A–C) and involved in bile secretion, neuroactive ligand–receptor interaction, and PPAR signaling pathway using KEGG analysis.
