Biochemical Background in Mitochondria Affects 2HG Production by IDH2 and ADHFE1 in Breast Carcinoma

Mitochondrial production of 2-hydroxyglutarate (2HG) can be catalyzed by wild-type isocitrate dehydrogenase 2 (IDH2) and alcohol dehydrogenase, iron-containing 1 (ADHFE1). We investigated whether biochemical background substrate concentration in breast cancer cells promote 2HG production. To estimate its role production, we quantified levels enantiomers using analytical approaches for metabolomics. By manipulation mitochondrial fluxes genetic pharmacological approaches, demonstrated the existence active competition between producing enzymes, i.e., IDH2 ADHFE1. Moreover, showed that distinct fractions enzyme molecules operate oxido-reductive modes, providing NADPH simultaneously. have also detected release urine patients undergoing adjuvant therapy a correlation with stages carcinoma development. In summary, provide vital outcomes towards biology possible future diagnosis carcinoma.
