SLC5A8 and neoplasm: The tumour‐suppressivefunction of SMCT1 is based on its ability to transport pyruvic acid, an inhibitor ofhistone deacetylases, into cells in non‐colonic tissues [471]; in the colon, the abilityof SMCT1 to transport butyric acid and propanoic acid, also inhibitorsof histone deacetylases, underlies the tumour‐suppressive function of thistransporter [179, 180, 213].
