Ascorbic Acid in Cancer Treatment: Let the Phoenix Fly

Area of Science:

• Oncology
• Biochemistry
• Pharmacology

Background:

• Vitamin C (ascorbic acid) is re-emerging as a potential anti-cancer agent.
• Recent studies explore intravenous ascorbate pharmacokinetics and novel mechanisms of action.
• Controversy surrounding Vitamin C in cancer treatment is being addressed by new research.

Purpose of the Study:

• To review the evolution of Vitamin C in cancer therapy.
• To provide insights into ascorbate pharmacokinetics and anti-cancer mechanisms.
• To outline preclinical and clinical evidence and suggest future research directions.

Main Methods:

• Literature review of ascorbate's role in cancer treatment.
• Analysis of pharmacokinetic data for intravenous ascorbate administration.
• Examination of proposed anti-cancer mechanisms, including oxidative stress and DNA demethylation.

Main Results:

• Ascorbate exhibits anti-cancer activity through hydrogen peroxide-induced oxidative stress.
• Ten-eleven translocation (TET) enzyme activation by ascorbate leads to DNA demethylation.
• Promising preclinical and clinical evidence supports ascorbate's therapeutic potential.

Conclusions:

• Vitamin C (ascorbic acid) demonstrates significant potential as an anti-cancer agent.
• Understanding ascorbate pharmacokinetics is crucial for optimizing its anti-cancer effects.
• Further research into ascorbate's mechanisms and clinical applications is warranted.
