Study Title | Branched-chain alpha-ketoacids are preferentially reaminated and activate protein synthesis in the rat heart |
Study Summary | Branched-chain amino acids (BCAA) and their cognate α-ketoacids (BCKA) are elevated in an array of cardiometabolic diseases. Here we demonstrate that the major metabolic fate of uniformly-13C-labeled α-ketoisovalerate ([U-13C]KIV) in the heart is reamination to valine. Activation of cardiac branched-chain α-ketoacid dehydrogenase (BCKDH) by treatment with the BCKDH kinase inhibitor, BT2, does not impede the strong flux of [U-13C]KIV to valine. |

Treatment Summary: | All heart perfusions underwent an initial 15-minute equilibration period with Krebs Ringer bicarbonate buffer containing 119 mM NaCl, 4.8 mM KCl, 2.6 mM CaCl2, 1.2 mM KH2PO4, 1.2 mM MgSO4, 25 mM NaHCO3, 11 mM glucose, and 0.05 mM L-carnitine at a flow rate of 12 ml/minute. After the equilibrium period, hearts were perfused for 30 minutes with 3% BSA, 100 µU/mL insulin, 0.4 mM palmitate, physiologic concentrations of amino acids, and either DMSO (Veh), BT2, or LY3351337. |
