Evidence for the presence of a guanine quadruplex forming region within a polypurine tract of the hypoxia inducible factor 1alpha promoter.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
The promoter of the hypoxia inducible factor 1 alpha (HIF-1alpha) gene has a polypurine/polypyrimidine tract (-65 to -85) overlapping or adjacent to several putative transcription factor binding sites, and we found that mutagenesis of this region diminished basal HIF-1alpha expression.
Endogenous adenosine, A1 adenosine receptor, and pertussis toxin sensitive guanine nucleotide binding protein mediate hypoxia induced AV nodal conduction block in guinea pig heart in vivo.

OBJECTIVE
The aim was to study the mechanism of global hypoxia induced atrioventricular (AV) nodal conduction block in vivo using a guinea pig model.
METHODS
Animals subjected to 10 min periods of global hypoxia, induced by decremental changes in O2 content in the inhaled gas mixture, were randomly
Rat cultured astrocytes release guanine-based purines in basal conditions and after hypoxia/hypoglycemia.

Brain ischemia stimulates release from astrocytes of adenine-based purines, particularly adenosine, which is neuroprotective. Guanosine, which has trophic properties that may aid recovery following neurological damage, is present in high local concentrations for several days after focal cerebral

Glutamate significantly increased levels of spontaneous chemiluminescence (CL) in rat hippocampal slices incubated under hypoxic conditions. Although it has been previously shown that guanine nucleotides (GN) displace glutamate from several of its receptors, in our study only GMP, as well as the
4-nitrobenzyloxycarbonyl derivatives of O(6)-benzylguanine as hypoxia-activated prodrug inhibitors of O(6)-alkylguanine-DNA alkyltransferase (AGT), which produces resistance to agents targeting the O-6 position of DNA guanine.

Hepatic ischemia-reperfusion (I/R) injury is a major challenge in liver resection and transplantation surgeries. Previous studies have revealed that guanine nucleotide-binding protein G(i)α2 (GNAI2) was involved in the progression of myocardial and cerebral I/R injury, but the role and function of

Hypoxia plays a significant role in solid tumors by the increased expression of hypoxia-inducible factor-1α (HIF-1α), which is known to promote cancer invasion and metastasis. Cancer-cell invasion dynamically begins with the degradation of the extracellular matrix (ECM) via invadopodia formation.
