Input: Question: Do ileal neuroendocrine tumors show elevated activation of mammalian target of rapamycin complex?
Answer: mTOR is overexpressed in ileal NETs. Additionally, the loss of ATRX expression was registered, thus underlying a tumorigenic role in a subgroup of these tumors. To enable potential therapeutic application of mTOR inhibitors, further trials with larger study groups are needed.
Output:
yes
