Overexpression of gankyrin in mouse hepatocytes induces hemangioma by suppressing factor inhibiting hypoxia-inducible factor-1 (FIH-1) and activating hypoxia-inducible factor-1

Overexpression of gankyrin in mouse hepatocytes induces hemangioma by suppressing factor inhibiting hypoxia-inducible factor-1 (FIH-1) and activating hypoxia-inducible factor-1.

Gankyrin (also called p28 or PSMD10) is an oncoprotein commonly overexpressed in hepatocellular carcinomas. It consists of 7 ankyrin repeats and interacts with multiple proteins including Rb, Cdk4, MDM2 and NF-κB. To assess the oncogenic activity in vivo, we produced transgenic mice that overexpress gankyrin specifically in the hepatocytes. Unexpectedly, 5 of 7 F2 transgenic mice overexpressing...

Hypoxia-inducible factor 1

Naïve T cells activated by antigen-presenting cells (APC) can be differentiated into at least four major types of T-helper (T(H)) cells: T(H)1, T(H)2, T(H)17 and inducible regulatory T cells (iTreg) based on their unique cytokine production profiles and characteristic functions.(1) T(H)1 produce interferon-γ (IFNγ) and are important for protective immune responses to intracellular viral, bacter...

Factor inhibiting hypoxia-inducible factor (FIH) and other asparaginyl hydroxylases.

FIH (Factor inhibiting hypoxia-inducible factor), an asparaginyl beta-hydroxylase belonging to the super-family of 2-oxoglutarate and Fe(II)-dependent dioxygenases, catalyses hydroxylation of Asn-803 of hypoxia-inducible factor, a transcription factor that regulates the mammalian hypoxic response. Only one other asparaginyl beta-hydroxylase, which catalyses hydroxylation of both aspartyl and as...
