Hypoxia-inducible factors (HIFs) are involved in adaptive and survival responses to hypoxic stress in mammals. In fish, very little is known about the functions of HIFs.
Cloning and expression analysis of two distinct HIF-alpha isoforms--gcHIF-1alpha and gcHIF-4alpha--from the hypoxia-tolerant grass carp, Ctenopharyngodon idellus.
