Task: Answer Verification
Input (English): Question: Does selenomethionine affect PSA secretion independent of its effect on LNCaP cell growth?
Answer: PSA secretion is not specifically inhibited by concentrations of selenomethionine corresponding to plasma selenium concentrations found in individuals supplemented with chemopreventive concentrations of selenized yeast. These data suggest that changes in serum PSA levels in individual patients during selenium supplementation is not an effect specific for PSA secretion, but rather may be a useful indicator for changes in disease progression in individual patients.
Output (English): no
