The results of Gene Ontology (GO) analysis demonstrated that these highly expressed genes in the HT with LVH group were principally associated with the function and structure of mitochondria, such as the oxidoreductase complex, mitochondrial inner membrane, mitochondrial matrix, ATP metabolic process, mitochondrial electron transport, mitochondrial respirasome, oxidative phosphorylation, and NADH dehydrogenase activity (Figure 4). Here, ENSG00000254051 is linked to hematocrit.
