Hypoxia-inducible factors may be made in larger than normal amounts by some types of cancer cells. This may cause cancer cells to grow and spread to other parts of the body. Also called HIF. One of a group of proteins that play an important role in how cells respond to changing levels of oxygen.

 

HIF-3 alpha transcripts are broadly expressed in human tissues and organs with some variants present at higher levels at embryonic stages. Many HIF-3 alpha variants contain an ODDD sequence and therefore protein stabilization under hypoxia is expected.

 

In this review we discuss the current understanding of HIF signaling in four different organ systems including the heart lung liver and kidney. We also discuss the divergent roles of HIF...

 

Rather than simply concatenating heterogeneous features HIF-FD designs modality-specific fraud-aware representation modules to capture the unique characteristics of different information sources. The main contribution lies in a fraud-oriented heterogeneous fusion framework rather than individual backbone architectures.

 

Hypoxia-inducible factor (HIF) is defined as a key transcription factor that mediates physiological responses to low oxygen levels by regulating the expression of genes involved in processes such as erythropoiesis angiogenesis and metabolism.

One study showed that flatfish turbot (Scophthalmus maximus) increased gene expression in the HIF pathway (HIF-1? HIF-2? HIF-3?) under acute hypoxia as they attempted to compensate for the lack of DO in the environment.

 

Under hypoxic conditions Hif-1 alpha translocates to the cell nucleus and associates with Hif-1 beta. This complex then binds to the HRE region of the DNA resulting in the transcription of genes that are involved in a multitude of processes including erythropoesis glycolysis and angiogenesis.
