Source:
Type:
Hypoxia-Inducible-Factor 1A (HIF1A gene, HIF1α, HIF-1α protein product)
-Dominantly expressed under hypoxia(low oxygen levels) in solid tumor cells
-HIF1A induces the expression of vascular endothelial growth factor (VEGF)
-High HIF-1α expression is associated with Poor prognosis
-Low HIF-1α expression is associated with Better prognosis

-Functionally, HIF-1α is reported to regulate glycolysis, whilst HIF-2α regulates genes associated with lipoprotein metabolism.
-Cancer cells produce HIF in response to hypoxia in order to generate more VEGF that promote angiogenesis

Key mediators of aerobic glycolysis regulated by HIF-1α.
-GLUT-1 → regulation of the flux of glucose into cells.
-HK2 → catalysis of the first step of glucose metabolism.
-PKM2 → regulation of rate-limiting step of glycolysis.
-Phosphorylation of PDH complex by PDK → blockage of OXPHOS and promotion of aerobic glycolysis.
-LDH (LDHA): Rapid ATP production, conversion of pyruvate to lactate;

HIF-1α Inhibitors:
-Curcumin: disruption of signaling pathways that stabilize HIF-1α (ie downregulate).
-Resveratrol: downregulate HIF-1α protein accumulation under hypoxic conditions.
-EGCG: modulation of upstream signaling pathways, leading to decreased HIF-1α activity.
-Emodin: reduce HIF-1α expression. (under hypoxia).
-Apigenin: inhibit HIF-1α accumulation.

2245- MF,    Quantum based effects of therapeutic nuclear magnetic resonance persistently reduce glycolysis
- in-vitro, Nor, NIH-3T3
Warburg↓, tNMR might have the potential to counteract the Warburg effect known from many cancer cells which are prone to glycolysis even under aerobic conditions.
Hif1a↓, combined treatment of tNMR and hypoxia (tNMR hypoxia) led to significantly altered HIF-1α protein levels, namely a further overall reduction in protein amounts
*Hif1a∅, Under normoxic conditions we did not find significant differences in Hif-1α mRNA and protein expression
Glycolysis↓, hypoxic tNMR treatment, driving cellular metabolism to a reduced glycolysis while mitochondrial respiration is kept constant even during reoxygenation.
*lactateProd↓, tNMR reduces lactate production and decreases cellular ADP levels under normoxic conditions
*ADP:ATP↓,
Pyruv↓, Intracellular pyruvate, which was as well decreased in hypoxic control cells, appeared to be further decreased after tNMR under hypoxia
ADP:ATP↓, tNMR under hypoxia further decreased the hypoxia induced decrease of the intracellular ADP/ATP ratio
*PPP↓, pentose phosphate pathway (PPP) is throttled after tNMR treatment, while cell proliferation is enhanced
*mt-ROS↑, tNMR under hypoxia increases mitochondrial and extracellular, but reduces cytosolic ROS
*ROS↓, but reduces cytosolic ROS
RPM↑, Because EMFs are known to affect ROS levels via the radical pair mechanism (RPM)
*ECAR↓, tNMR under normoxic conditions reduces the extracellular acidification rate (ECAR)

3476- MF,    Pulsed Electromagnetic Fields Stimulate HIF-1α-Independent VEGF Release in 1321N1 Human Astrocytes Protecting Neuron-like SH-SY5Y Cells from Oxygen-Glucose Deprivation
- in-vitro, Stroke, 1321N1 - in-vitro, Park, NA
*VEGF↑, PEMF exposure induced a time-dependent, HIF-1α-independent release of VEGF from 1321N1 cells
*eff↑, further corroborate their therapeutic potential in cerebral ischemia.
*neuroP↑, emerging evidence has identified PEMFs as an attractive non-invasive strategy also for the treatment of different neuropathological conditions
*other↑, PEMF stimulation have been studied in the context of Parkinson’s disease [2,3], Alzheimer’s disease [4], and neuropathic pain
*eff↑, PEMFs significantly reduced neuroinflammation and pro-apoptotic factors and determined a reduction of infarct size, implicating PEMFs as possible adjunctive therapy for stroke patients
*Inflam↓, anti-inflammatory effect of PEMFs in microglial cells
*Hif1a∅, PEMFs exposure did not modulate HIF-1α expression confirming that the PEMF-mediated VEGF production was independent by the activation of this transcriptional regulator of cellular response to hypoxia
