Expression and/or activity of the SVCT2 ascorbate transporter may be decreased in many aggressive cancers, suggesting potential utility for sodium bicarbonate and dehydroascorbic acid in cancer therapy

This hypothesis article posits that aggressive cancers often exhibit reduced expression or activity of the SVCT2 transporter, leading to suboptimal intracellular ascorbate levels. This deficiency may result in elevated activity of hypoxia-inducible factor-1 (HIF-1), promoting tumor aggressiveness. The acidic microenvironment of tumors further impairs SVCT2 function. The author suggests that

The Pharmacokinetics of Vitamin C

This 2019 review presents a comprehensive overview of the pharmacokinetics of vitamin C, focusing on its absorption, distribution, metabolism, and excretion. It details the role of sodium-dependent vitamin C transporters SVCT1 and SVCT2 and the involvement of GLUT transporters in the cellular uptake of dehydroascorbic acid. Oral vitamin C absorption
