GSEA (Gene Set Enrichment Analysis) of the TCGA lung adenocarcinoma RNA‐seq data (Campbell et al, 2016) also indicate that the expression of oxidative phosphorylation pathway genes is highly enriched in DGUOK high lung adenocarcinoma patients (Fig 3B and C), implicating a role for DGUOK in the regulation of mitochondrial respiration in these patients. This evidence concerns the gene DGUOK and lung adenocarcinoma.
