Long-term Anoxia in Crucian Carp: Changes in the Levels of Amtno Acid and Monoamine Neurotransmitters in the Brain, Catecholamtnes in Chromafftn Tissue, and Liver Glycogen
Crucian carp (Carassius carassius L.), which are extremely anoxia-tolerant, were exposed to 17 days of anoxia at 8°C. One group of fish was transferred to normoxic water for 1̂ 8 h immediately after the anoxic period. All the eight amino acids measured in brain (including four putative neurotransmitters) were more or less strongly affected by anoxia. Gamma-aminobutyric acid (GABA) displayed a ne...

متن کاملUtilization of the Ethanol Pathway in Carp following Exposure to Anoxia
1. Crucian carp (Carassius carassius L.) and Common carp (Cyprinus carpio L.) were subjected to 2h progressive hypoxia followed by up to 6 h anoxia in closed respirometers at 15 °C. 2. The concentrations of glycogen, glucose, phosphoryl creatine, alanine, succinate, lactate, ethanol and ammonia were determined in whole Crucian carp following exposure to both hypoxia and anoxia. 3. Ethanol and l...
متن کاملOxygen- and temperature-dependent expression of survival protein kinases in crucian carp (Carassius carassius) heart and brain.
Living without oxygen is limited to very few vertebrates, one species being the fresh water fish crucian carp (Carassius carassius), which can survive months of anoxia at low temperatures. Mammalian heart and brain are particularly intolerant to oxygen deprivation, yet these organs can be conditioned to display increased resistance, possibly due to activation of several protein kinases. We hypo...
متن کاملDifferential regulation of AMP-activated kinase and AKT kinase in response to oxygen availability in crucian carp (Carassius carassius).
We investigated whether two kinases critical for survival during periods of energy deficiency in anoxia-intolerant mammalian species, AMP-activated kinase (AMPK), and protein kinase B (AKT), are equally important for hypoxic/anoxic survival in the extremely anoxia-tolerant crucian carp (Carassius carassius). We report that phosphorylation of AMPK and AKT in heart and brain showed small changes ...
