Definition: 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 immunoreactive endomorphin 2 generated extracellularly in rat isolated L4,5 dorsal root ganglia by DPP-IV?
Answer: In rat isolated dorsal root ganglia the combination of presumed biosynthetic precursor of endomorphin 2 (E2), Tyr-Pro with the dipeptidyl peptidase IV (DPP-IV) inhibitor Ile-Pro-Ile generated 1.60+/-0.37 pg/mg Wet Tissue Weight_30 min E2-IR in the bathing fluid (n=4) with an 8-fold increase upon depolarization whereas the tissue content was low (0.50+/-0.08 pg/mg_WTW). Substance P, as determined by ELISA in the pilot experiments, was found almost exclusively within the tissues. It is concluded that E2-IR was generated extracellularly by a membrane-bound DPP-IV, which was switched to "synthase" mode by the hydrolase inhibitor Ile-Pro-Ile. DPP-IV was depolarization-sensitive in "synthase" functional mode.
Output:
yes
