MT-ND1 and neoplasm: Notably, the upregulation of several genes encoding mitochondrial proteins associated with oxidative phosphorylation, for instance, MT-CYO2, MT-CYO3, MT-ND4 and MT-ND1, were observed in the C0-Res, C1-TAM and C2-M2 of the CCII group (Table S4), which might be associated with active cellular metabolism during tumour growth.
