KRAS-mutated NSCLC cells expressed higher levels of enzymes involved in glycolysis (glyceraldehyde 3-phosphate dehydrogenase—GAPDH, pyruvate kinase isozyme M2—PKM2, lactate dehydrogenase A—LDHA and lactate dehydrogenase B—LDHB) and PPP (glicose-6-fosfato dehydrogenase—G6PD, transketolase—TKT and 6-phosphogluconate dehydrogenase—6PGD) compared with nonmalignant cells [41]. Here, TKT is linked to non-small cell lung carcinoma.
