GAPDH and neoplasm: It is discovered that ZIF‐8 (zinc imidazolate metal–organic frameworks ) can induce abrupt intracellular Zn2+ elevation preferentially in melanoma cells, and then achieve effective glycolysis blockade through “Zn2+ interference”‐triggered decrease of NAD+ and inactivation of GAPDH, making it a powerful tumor energy nanoinhibitor.
