KSCBi005-A-10(hiPSC-HIF1αKO), a HIF1α knockout human induced pluripotent stem cell line, for demonstrating the role of cellular response to hypoxia

Stem Cell Research
Under hypoxia, hypoxia-inducible factor (HIF)-1 regulates hypoxia-inducible genes, such as vascular endothelial growth factor (VEGF) and its receptors VEGFR1 and VEGFR2.

Septin4 promotes cardiomyocytes apoptosis by enhancing the VHL-mediated degradation of HIF-1α

Cell Death Discovery, 2021
Septin4, a protein localized at mitochondrion, can promote cells apoptosis mainly by binding XIAP (X-linked inhibitors of apoptosis), however, nothing is known about the role and mechanism of Septin4 in cardiomyocytes apoptosis. Here in the current study,

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Hypoxia-Inducible Factor 1α Polymorphisms and Early-Stage Cervical Cancer

, 2011
Background:Human papillomavirus can stabilize and induce hypoxia-inducible factor 1α (HIF-1α) protein, which is associated with diminished response to treatment and poor prognosis for cervical cancer. Hypoxia-inducible factor 1α polymorphisms (1772C>T

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Effects of acute hypoxia exposure with different durations on activation of Nrf2-ARE pathway in mouse skeletal muscle.

PLoS ONE, 2018
BackgroundHypoxia training enhances the endurance capacity of athletes. This response may in part be attributed to the hypoxia-induced increase in antioxidant capacity in skeletal muscles.

mRNA expression profile of selected oxygen sensing genes in the lung during recovery from chronic hypoxia

Biological Research, 2013
This study analyzed the time dependence decay of the mRNA of selected genes important for the hypoxia response. The genes chosen were the two isoforms of hypoxia-inducible factors, the three isoforms of the prolyl hydroxylase domain protein, the vascular

Hypoxia promotes uveal melanoma invasion through enhanced Notch and MAPK activation. [PDF]

PLoS ONE, 2014
The transcriptional response promoted by hypoxia-inducible factors has been associated with metastatic spread of uveal melanoma. We found expression of hypoxia-inducible factor 1α (HIF-1α) protein in well-vascularized tumor regions as well as in four ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Factor inhibiting HIF (FIH-1) promotes renal cancer cell survival by protecting cells from HIF-1α-mediated apoptosis.

, 2011
BACKGROUND: Clear cell renal cell carcinoma (CCRCC) is the commonest form of kidney cancer. Up to 91% have biallelic inactivation of VHL, resulting in stabilisation of HIF-α subunits.
