HIF at a glance.

چکیده
Hypoxia-inducible factor (HIF) is a sequence-specific DNA-binding protein that can promote or repress the transcription of a broad range of genes that are involved in maintaining biological homeostasis. HIF is mostly non-functional in oxygenated cells but becomes active under specific conditions, including lowoxygen (hypoxic) stress. HIF is a heterodimeric complex that is composed of an oxygen-destructible α-subunit and an oxygen-indestructible β-subunit. Three isoforms of the α-subunit and two isoforms of the β-subunit are thought to be involved in the in vivo response to hypoxia.

The transcription of Hypoxia-inducible factors (hif-1, hif-2) during normal development of Beluga sturgeon (Huso huso Linnaeus, 1758)
In the present study, the levels of the hypoxia-inducible factors (hif-1, hif-2) transcripts were evaluated during development of an ancient fish species, Beluga sturgeon (Huso huso) in a normal oxygen environment. The transcripts of hif-1, hif-2 were detected in all developmental time-points of H. huso from embryos to juvenile fish. Changes in normalized hif-1, hif-2 mRNA expression by using t...

Background and Aim: One of the most common metabolic diseases is diabetes with hyperglycemic properties and endogenous insulin dysfunction. This study aimed to evaluate the effect of 10 weeks HIIT on HIF-1α gene expression in heart tissue of rats with type 2 diabetes. Methods: In this experimental study, 36 Wister rats with a mean weight of 200±58g were randomly assigned to control, diabetic,...
