Metabolic shift in liver: Correlation between perfusion temperature and hypoxia inducible factor-1α

Reduced Liver Fibrosis in Hypoxia-inducible Factor-1α-Deficient Mice

Liver fibrosis is characterized by excessive deposition of extracellular matrix in the liver during chronic injury. During early stages of this disease, cells begin to synthesize and secrete profibrotic proteins that stimulate matrix production and inhibit matrix degradation. Although it is clear that these proteins are important for development of fibrosis, what remains unknown is the mechanis...

Correlation between polymorphisms of hypoxia-inducible factor-1α Pro582Ser and type 2 diabetic nephropathy.

We examined the correlation between gene polymorphisms in hypoxia-inducible factor-1α (HIF-1α) Pro582Ser and type 2 diabetic nephropathy (DN). A total of 244 subjects with type 2 diabetes were recruited. The 1285-bp locus polymorphism of HIF-1α exon was detected using polymerase chain reaction-restriction fragment length polymorphism. C/T single nucleotide polymorphisms were detected at the sit...

Hypoxia, Hypoxia-Inducible Factor-1α, and Innate Antileishmanial Immune Responses

Low oxygen environments and accumulation of hypoxia-inducible factors (HIFs) are features of infected and inflamed tissues. Here, we summarize our current knowledge on oxygen levels found in Leishmania-infected tissues and discuss which mechanisms potentially contribute to local tissue oxygenation in leishmanial lesions. Moreover, we review the role of hypoxia and HIF-1 on innate antileishmania...

Molecular responses to hypoxia-inducible factor 1α and beyond.

Cellular response to changes in oxygen tension during normal development or pathologic processes is, in part, regulated by hypoxia-inducible factor (HIF), an oxygen-sensitive transcription factor. HIF activity is primarily controlled through post-translational modifications and stabilization of HIF-1α and HIF-2α proteins and is regulated by a number of cellular pathways involving both oxygen-de...
