This study was undertaken to examine the receptor selectivity of Met-enkephalin-Arg6-Phe7 (MERF) employing radioreceptor binding assays in human cerebral cortex membranes, and to elucidate the responsible receptors that mediate the regulatory action of MERF on high (20 mM) K+-stimulated release

In previous communications [4, 38] we published that [3H]Met-enkephalin-Arg6-Phe7 (MERF) binds to opioid (kappa2 and delta) and sigma2 sites in frog and rat brain membrane preparations, however no binding to kappa1 sites could be established. In the present paper we

The opioid peptides are potent inhibitors of gastric somatostatin-like immunoreactivity (SLI) secretion from the isolated perfused rat stomach. In addition, inhibition of SLI secretion induced by vagal stimulation is partially blocked by naloxone, indicating that endogenously released opioid peptides probably

[3H]Met-enkephalin-Arg6-Phe7 (MERF) has been shown to label opioid (kappa2 and delta) and sigma2 sites in rat and frog brain membrane preparations, and no specific binding to kappa1 opioid receptors could be established (refs. 6 and 8). In this study the

The introduction of genome-wide shRNA and CRISPR libraries has facilitated cell-based screens to identify loss-of-function mutations associated with a phenotype of interest. Approaches to perform analogous gain-of-function screens are less common, although some reports have utilized arrayed viral expression libraries
