MT-ATP6 and neoplasm: Metascape analysis revealed that the ATP metabolic process and response to oxygen levels pathway were enriched in NEAT1+ tumor cells (Fig. 4D and Additional file 1: Fig. S10A), where oxidative phosphorylation (OXPHOS)-related genes, COX1, COX2, COX3, ND1, ND2, ND4, and ATP6, were clustered (Additional file 2: Table S2).
