Task: Answer Verification
Input (English): Question: Is elevation of tissue α-tocopherol levels by conjugated linoleic acid in C57BL/6J mice associated with changes in vitamin E absorption or α-carboxyethyl hydroxychroman production?
Answer: The increase in vitamin E status in CLA-fed mice is not due to altered absorption and metabolism of vitamin E but might be related to the induction of α-tocopherol transfer protein expression in the liver. The regulation of the activities of catalase and glutathione peroxidase by CLA is not mediated by vitamin E accumulation in the liver.
Output (English): no
