According to news reporting out of Hunan, People’s Republ ic of China, by NewsRx editors, research stated, “Mitochondrial dysfunction and immune cell infiltration play crucial yet incompletely understood roles in the p athogenesis of calcific aortic valve disease (CAVD). This study aimed to identif y immune-related mitochondrial genes critical to the pathological process of CAV D using multiomics approaches.” Our news journalists obtained a quote from the research from Hunan Provincial Pe ople’s Hospital, “The CIBERSORT algorithm was employed to evaluate immune cell i nfiltration characteristics in CAVD patients. An integrative analysis combining weighted gene coexpression network analysis (WGCNA), machine learning, and summa ry data-based Mendelian randomization (SMR) was performed to identify key mitoch ondrial genes implicated in CAVD. Spearman’s rank correlation analysis was also performed to assess the relationships between key mitochondrial genes and infilt rating immune cells. Compared with those in normal aortic valve tissue, an incre ased proportion of M0 macrophages and resting memory CD4 T cells, along with a d ecreased proportion of plasma cells and activated dendritic cells, were observed in CAVD patients. Additionally, eight key mitochondrial genes associated with C AVD, including PDK4, LDHB, SLC25A36, ALDH9A1, ECHDC2, AUH, ALDH2, and BNIP3, wer e identified through the integration of WGCNA and machine learning methods. Subs equent SMR analysis, incorporating multiomics data, such as expression quantitat ive trait loci (eQTLs) and methylation quantitative trait loci (mQTLs), revealed a significant causal relationship between ALDH9A1 expression and a reduced risk of CAVD. Moreover, ALDH9A1 expression was inversely correlated with M0 macropha ges and positively correlated with M2 macrophages. These findings suggest that i ncreased ALDH9A1 expression is significantly associated with a reduced risk of C AVD and that it may exert its protective effects by modulating mitochondrial fun ction and immune cell infiltration. Specifically, ALDH9A1 may contribute to the shift from M0 macrophages to anti-inflammatory M2 macrophages, potentially mitig ating the pathological progression of CAVD.”
