Other claims from this paper (11)
- Intervention effect Heat shock increased GABA accumulation several-fold within four hours.
- Observation GABA utilization also increased during heat shock.
- Intervention effect Heat shock did not increase levels of the three specified GABA metabolic enzymes.
- Mechanism Protein synthesis was suggested to be unnecessary to maintain enzyme levels during heat shock.
- Intervention effect GAD level decreased in heat-adapted cells.
- Intervention effect GABA increased somewhat in heat-adapted cells.
- Observation Alanine, glutamate and aspartate were the most heavily labeled amino acids after labeled GABA feeding.
- Intervention effect With gabaculine, no amino acids other than GABA were labeled.
- Intervention effect GAD kinetic and response curves were identical between heat-shocked and control cells.
- Observation Removing small solutes revealed no evidence of GAD activation or inhibition by low molecular weight effectors.
- Mechanism The authors proposed combined acidification, temperature and compartmentation effects for increased GABA biosynthesis.
