Task: Answer Verification
Input (English): Question: Do serotonin and melatonin play a prominent role in the growth of prostate cancer cell lines?
Answer: Serotonin receptor antagonists and agonists as well as MLT influence viability and apoptosis of PCa cell lines at supraphysiologic concentrations. In contrast to other reports, our results do not support a regulatory role of serotonin or MLT receptor activation or inhibition in PCa growth.
Output (English): no
