Highlights PPAR genes in CHF; hypothesis-generating and requires validation before clinical consideration.
BACKGROUND: The role of PPAR signaling and its associated genes in the pathogenesis and progression of chronic heart failure (CHF) remains elusive. METHODS: We accessed the gene expression profile and relevant baseline information of CHF samples from the Gene Expression Omnibus (GEO) database, specifically from the GSE57338 project. RESULTS: From GSE57338 project, we derived the expression value of 126 PPAR-related genes. A protein-protein interaction network was then established to illustrate potential protein interactions. ClueGO analysis results revealed that these genes predominantly participate in functions such as export across plasma membrane, regulation of lipid metabolic process, fatty acid metabolism, circulatory system vascular processes, alcohol metabolism, triglyceride metabolism and regulation of lipid localization and response to nutrient. Using the cytohubba plug-in in Cytoscape, we pinpointed ACADM, PPARG and CPT2 as potential central molecules in HF pathogenesis and progression. Subsequent Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis delved into the potential biological role of these three genes in CHF. Immune infiltration analysis suggested that the infiltration level of neutrophils and M2 macrophages might be notably influenced by these genes, thereby playing a role in the CHF mechanism. CONCLUSIONS: Our research provides a comprehensive insight into the significance of PPAR associated genes in CHF development. Notably, the genes ACADM, PPARG and CPT2 emerged as potential targets for clinical interventions.

Ke et al. (2023) conducted an observational in Chronic Heart Failure (n=313). PPAR-related gene expression vs. Control samples without chronic heart failure was evaluated on Identification of hub genes in the pathogenesis and progression of chronic heart failure. Bioinformatics analysis identified ACADM, PPARG, and CPT2 as pivotal hub genes in the pathogenesis and progression of chronic heart failure, potentially influencing neutrophil and M2 macrophage infiltration.
