Suppressive Effects of Neuromedin U Receptor 2-Selective Peptide Agonists on Appetite and Prolactin Secretion in Mice.
Article in ACS medicinal chemistry letters, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Neuromedin U receptor 2 (NMUR2), which is expressed in the central nervous system (CNS) including the hypothalamus, has been noted as a therapeutic target against obesity. We previously reported that intranasal administration of CPN-219, a NMUR2-selective hexapeptide agonist, suppresses body weight gain in mice; however, there is no detailed information regarding its CNS effects. Recently, in addition to appetite suppression, stress responses and regulation of prolactin (PRL) secretion have also attracted attention. NMUR2 expressed in the hypothalamic tuberoinfundibular dopaminergic neurons has emerged as an alternative target for treating hyperprolactinemia. Here, CPN-219 decreased food intake up to 24 h after administration at a dose of 200 nmol, resulting in body weight gain suppression, although grooming and anxiety-like behaviors were transiently induced. Interestingly, the restraint stress-induced increase in plasma PRL levels was significantly suppressed at a lower dose of 20 nmol, indicating the potential for drug development as an anti-PRL agent of NMUR2-selective agonists.
