... ( Borowiec et al., 2015 ) or by a shift in haemoglobin isoforms ( Pan et al., 2017 ). Second, LDH activity was increased in fish acclimated in constant hypoxia, which could be due to a prioritization of the anaerobic metabolic pathway ( Shoubridge and Hochachka, 1980 ; Pastoris et al., 1995 ; Omlin...

The global metabolomic and enzymatic analyses revealed production of metabolites characteristic of oxygen-independent pathways of ATP generation (lactate and succinate) in the depressed metabolic state, which suggests that anaerobic metabolism was the main energy supply pathway under...

...) are among the most hypoxia-tolerant mammals, capable of drastically reducing their metabolic rate in acute hypoxia while staying active and alert. We hypothesized that a key component of remaining active is an increased reliance on anaerobic metabolism during severe hypoxia. To test this hypothesis, we...
