Question: Question: Does the Drosophila Chmp1 protein determine wing cell fate through regulation of epidermal growth factor receptor signaling?
Answer: Drosophila Chmp1 negatively regulates DER signaling, likely through its role in MVB formation. Loss of Chmp1 activity in the Drosophila wing induces a cell fate change from intervein to vein that should provide a useful tool for future studies of ESCRT protein activity.

Answer: yes


Question: Question: Do nAT1 genotypes predict response to mesalamine in patients with ulcerative colitis?
Answer: NAT1 genotypes do not predict response or side effects to mesalamine in patients with UC. Variations caused by non-genomic effects may be associated with the clinical response to 5-ASA.

Answer: no


Question: Question: Does [ TNM-Classification of localized prostate cancer : The clinical T-category correspond to the required demands ]?
Answer: For localized PCa there is low agreement between clinical and pathologic T category, thus, often leading to understaging. An adaptation of the T classification of the TNM system with division into "not palpable" and "palpable" appears sufficient for a prognostic prediction.

Answer:
no
