PDK4 and neoplasm: Lipid metabolism‐associated genes were significantly higher in peripheral tumours in LumB, like pyruvate dehydrogenase kinase 4 (PDK4) (t = −3.08, p = .008), CD36 molecule (CD36) (t = −3.09, p = .007), endothelin 1 (EDN1) (t = −2.48, p = .02), lipoprotein lipase (LPL) (t = −2.46, p = .02), leptin receptor (LEPR) (t = −2.66, p = .01).
