CUR, Curcumin: Click to Expand ⟱
Features:
Curcumin is the main active ingredient in Tumeric. Member of the ginger family.Curcumin is a polyphenol extracted from turmeric with anti-inflammatory and antioxidant properties.
- Has iron-chelating, iron-chelating properties. Ferritin. But still known to increase Iron in Cancer cells.
- GSH depletion in cancer cells, exhaustion of the antioxidant defense system. But still raises GSH↑ in normal cells.
- Higher concentrations (5-10 μM) of curcumin induce autophagy and ROS production
- Inhibition of TrxR, shifting the enzyme from an antioxidant to a prooxidant
- Strong inhibitor of Glo-I, , causes depletion of cellular ATP and GSH
- Curcumin has been found to act as an activator of Nrf2, (maybe bad in cancer cells?), hence could be combined with Nrf2 knockdown
-may suppress CSC: suppresses self-renewal and pathways (Wnt/Notch/Hedgehog).
Clinical studies testing curcumin in cancer patients have used a range of dosages, often between 500 mg and 8 g per day; however, many studies note that doses on the lower end may not achieve sufficient plasma concentrations for a therapeutic anticancer effect in humans.
• Formulations designed to improve curcumin absorption (like curcumin combined with piperine, nanoparticle formulations, or liposomal curcumin) are often employed in clinical trials to enhance its bioavailability.

Hif1a, HIF1α/HIF1a: Click to Expand ⟱
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.
