Polycyclic aromatic hydrocarbon (PAH) compounds including 3‐methylcholanthrene induce harmful reactive intermediates and reactive oxygen species. This study reports the effect of 3‐methylcholanthrene on the accumulation of vitamin C and the expression of vitamin C transporters. ODS rats were given l ‐ascorbic acid daily and intraperitoneal injections of 10 mg 3‐methylcholanthrene in total. On day 10, vitamin C concentrations and the expression of vitamin C transporter in the tissues were measured. As a result, the levels of sodium‐dependent vitamin C transporter (SVCTs) 1 and the l ‐ascorbic acid concentration in 3‐methylcholanthrene‐treated livers and hepatocytes have increased significantly. However, the content of vitamin C in the urine and TBARS in the liver have not changed. These results suggest that the administration of 3‐methylcholanthrene elevates the requirement for vitamin C via (SVCTs) 1 due to xenobitics‐metabolizing, such as the induction of cytochrome P450 family. © 2011 Wiley Periodicals, Inc.
