Instructions: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Input: Question: Is elevation of tissue -tocopherol levels by conjugated linoleic acid in C57BL/6J mice associated with changes in vitamin E absorption or -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 -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:
no
