“…Following the “clusterProfiler” package, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to investigate the cellular and molecular functions of MRGs. In order to assess the correlation between the mitochondria-related genes and lncRNAs, we performed Pearson correlation analysis using the “corrplot” package and defined lncRNAs with P value < 0.001 and absolute correlation coefficient > 0.4 as MALs [48] , [49] . The network of MRGs and their co-expression MALs was generated via the “igraph” package.…”
