TGFB1 and cardiomyopathy: Based on the GO/KEGG and GSEA enrichment analysis of the DEgenes obtained after the intersection analysis, the regulation of phospholipase activity, cAMP signaling pathway, G alpha signaling events, fibroblast proliferation, TGF-β signaling pathway, vascular endothelial growth factor (VEGF) receptor signaling pathway, NF-κB transcription factor activity, calcium-mediated signaling, and other cardiomyopathy-related signaling pathways were enriched.
