Integrated analysis of biochemical, transcriptomic, and metabolomic response mechanisms in Ussuri catfish (Pseudobagrus ussuriensis) under acute heat stress.

Fish metabolism, growth, development, and physiological conditions are highly sensitive to fluctuations in water temperature. The Ussuri catfish (Pseudobagrus ussuriensis) is an important native economic species in China. However, research on heat stress in P.

siRNA silencing and hypoxia challenge indicate that the function of common carp (Cyprinus carpio) hif-1αb genes are tightly linked to hif-1αa and hif-3α genes.

Background: Fishes are susceptible to hypoxia stress, while the common carp is known for its high tolerance to hypoxia. The hypoxia-inducible factor (HIF) pathway directly regulates the cell's response to hypoxia. Still, it is currently unknown which members of the hif-α genes are present in common carp and their specific functions.

Transcriptome Analysis of Brain and Skin Reveals Immune Responses to Acute Hypoxia and Reoxygenation in .

is an unscaled fish that is more susceptible to skin damage than scaled fish. To investigate the impacts of hypoxia and reoxygenation on skin and brain immunity, juvenile were subjected to hypoxia conditions (DO: 0.8 ± 0.
