Butyrate Suppresses Proliferation of Colon Cancer Cells via Targeting Pyruvate Kinase M2 and Metabolic Reprogramming


ABSTRACT: How butyrate interrupts the metabolism of cancer cells and leads to the suppression of cell proliferation remains unclear. We employed a metabolomics-proteomics combined approach to explore the link between butyrate-mediated proliferation arrest and cell metabolism. Metabolomics study revealed a remodeled metabolic profile with pronounced accumulation of pyruvate. A proteomics-based approach reveals PKM2 as a direct target of butyrate. it activates PKM2 via promoting its dephosphorylation and tetramerization.Our study provides a mechanistic link between PKM2-induced metabolic remodeling and the anti-tumorigenic function of butyrate.
