AKT1 and lung cancer: KEGG pathway analysis revealed significant upregulation in the lung cancer group of pathways including signal transduction (e.g., HIF-1 signaling pathway, PI3K-Akt signaling pathway), carbohydrate metabolism (e.g., Citrate cycle [TCA cycle], Glycolysis/Gluconeogenesis), nucleotide metabolism (Pyrimidine metabolism, Purine metabolism), amino acid metabolism (Cysteine and methionine metabolism, Alanine, aspartate, and glutamate metabolism), and energy metabolism (Oxidative phosphorylation, Nitrogen metabolism).
