Effects of Cholinergic and Opioid Antagonists on In Vitro Release of Met-Enkephalin, Somatostatin and Insulin-like Growth Factor-1 by and PENK Expression in Crop, Proventriculus and Duodenum of Newly Hatched Chickens. [PDF]
Animals (Basel)The gastrointestinal (GI) tract is under neural, endocrine and paracrine control. The release (basal and in the presence of either cholinergic and opioid antagonists) of Met-enkephalin, insulin-like growth factor 1 (IGF-1) and somatostatin (SRIF) was ...

Age-Related Decreases in Colonic Neurokinin A Content and Release Monitored Using Electrochemical Immunosensors. [PDF]
Neurogastroenterol MotilA 3D‐printed electrochemical immunosensor revealed significant age‐related reductions in colonic Neurokinin A (NKA) content and release. Decreased fecal NKA levels mirrored tissue changes, highlighting the potential of NKA as a noninvasive biomarker of age‐related bowel dysfunction.

Highly sensitive in vivo detection of dynamic changes in enkephalins following acute stress in mice. [PDF]
ElifeEnkephalins are opioid peptides that modulate analgesia, reward, and stress. In vivo detection of enkephalins remains difficult due to transient and low endogenous concentrations and inherent sequence similarity.
