“…To elucidate the effects of hypoxic stress on the heart of rainbow trout, biochemical indices and hypoxia-related gene expression were measured during moderate (4.5±0.1 mg/L) and severe hypoxia (3.0±0.1 mg/L) stress for 4 h, 8 h, 12 h, and 24 h; moderate hypoxia for 1 month (TMM); severe hypoxia for 1 month (TMM); and reoxygenation (8.5±0.1 mg/L) for 12 h and 24 h using enzyme activity assays and quantitative real time polymerase chain reaction (RT-qPCR). The results showed that the pyruvate kinase (PK), total cholesterol (TC), lactic acid (LD), and glutamine aminotransferase (GPT) reactivates increased at 8 h, decreased at 24 h, and were significantly higher than the control levels after reoxygenation (P < 0.05) under moderate hypoxic stress. …”
