NMDA Receptors in POMC Neurons Connect Exercise With Insulin Sensitivity.
Article in Diabetes, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Increased arcuate proopiomelanocortin (POMC) neuron activity improves glucose metabolism and reduces appetite, facilitating weight loss. We recently showed that arcuate POMC neurons are activated by exercise. However, the role of excitatory glutamatergic input in these neurons and the metabolic outcomes of exercise remains undefined. To investigate this, we developed a mouse model with NMDA receptors (NMDARs) selectively deleted from POMC neurons of adult mice. We performed metabolic assessments, including the monitoring of body weight, body composition analysis, and glucometabolic tolerance tests. We also examined the metabolic outcomes of these mice in response to exercise, including changes in arcuate POMC neuronal activity and insulin sensitivity. Loss of NMDARs in POMC neurons failed to alter body weight or body composition. Notably, however, we did observe a marked impairment in glucose tolerance and insulin sensitivity. Additionally, exercise resulted in activation of arcuate POMC neurons and a sustained improvement in insulin sensitivity, an effect that was abrogated in mice deficient for NMDARs in POMC neurons when compared with their respective sedentary controls. This underscores an important link among exercise, hypothalamic neuron function, and metabolic health. Moreover, this highlights an underappreciated role of hypothalamic POMC neurons in mediating beneficial effects of exercise on glucose metabolism. ARTICLE HIGHLIGHTS:
