1 Glutamine dose-dependently increased GAD-mediated formation of GABA, whereas glucose metabolism shunts part of this GABA to mitochondrial catabolism, involving alpha-KG-induced activation of GABA-T. Glucose 4-aminobutyrate aminotransferase Homo sapiens
2 In absence of extracellular glutamine, glucose also contributed to GABA formation through aminotransferase generation of glutamate from alpha-KG; this stimulatory effect increased GABA release only when GABA-T activity was suppressed. Glucose 4-aminobutyrate aminotransferase Homo sapiens
3 Glucose inhibits glutamine-driven GABA formation and release through increasing GABA-T shunt activity by its cellular metabolism. Glucose 4-aminobutyrate aminotransferase Homo sapiens
