Features:
Metronomic chemotherapy refers to the therapeutic strategy of administering chemotherapeutic drugs at relatively low, minimally toxic doses on a frequent or continuous schedule without extended rest periods. This dosing regimen contrasts with traditional maximum tolerated dose (MTD) chemotherapy, which involves high doses given intermittently with breaks to allow patient recovery.

-The drugs are given in lower doses and more frequently (often daily or multiple times a week)
-Aims to consistently impair tumor growth mechanisms and potentially minimize the chance for cancer cells to recover
-Aims to consistently impair tumor growth mechanisms and potentially minimize the chance for cancer cells to recover
-With a lower dose intensity, patients often experience fewer and less severe side effects

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.
