Metabolic Effects of Blocking Lactate Transport in Brain Cortical Tissue Slices Using an Inhibitor Specific to MCT1 and MCT2

Rae, Caroline; Nasrallah, Fatima A.; Broer, Stefan


A novel inhibitor of lactate transport, AR-C122982, was used to study the effect of inhibiting the monocarboxylate transporters MCT1 and MCT2 on cortical brain slice metabolism. We studied metabolism of l-[3-13C]lactate, and d-[1-13C]glucose under a range of conditions. Experiments using l-[3-13C]lactate showed that the inhibitor AR-C122982 altered exchange of lactate. Under depolarizing conditions, net flux of label from d-[1-13C]glucose was barely altered by 10 or 100 nM AR-C122982. In the...[Show more]
