Natural compounds regulate glycolysis in hypoxic tumor microenvironment.

Area of Science:

• Oncology
• Biochemistry
• Metabolic pathways

Background:

• The Warburg effect, elevated glycolysis in cancer cells, is a hallmark of cancer.
• Hypoxia-inducible factor-1 (HIF-1) significantly drives tumor glycolysis and the Warburg effect.
• Inhibiting HIF-1-dependent glycolysis is a promising cancer therapy strategy.

Purpose of the Study:

• To review the role of natural compounds in regulating tumor glycolysis.
• To focus on glycolysis within the hypoxic tumor microenvironment.
• To explore natural inhibitors of key glycolytic regulators.

Main Methods:

• Literature review of natural compounds targeting tumor glycolysis.
• Analysis of HIF-1's role in upregulating glucose transporters (GLUT) and glycolytic enzymes.
• Examination of natural small molecules as inhibitors of GLUT, hexokinase, and pyruvate kinase M2.

Main Results:

• Natural compounds offer potential as inhibitors of tumor glycolysis.
• Targeting GLUT, hexokinase, and pyruvate kinase M2 with natural molecules is a key strategy.
• Inhibition aims to suppress cancer cell energy metabolism and enhance treatment sensitivity.

Conclusions:

• Natural compounds are valuable in targeting the Warburg effect and tumor hypoxia.
• Inhibiting HIF-1-mediated glycolysis with natural products can suppress cancer progression.
• This approach enhances tumor cell susceptibility to radio- and chemotherapy.
