Evaluation of Proopiomelanocortin (POMC) and neuropeptide Y (NPY) levels in bipolar and unipolar patients.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveEvidence suggests that stressful life experiences contribute significantly to the aetiology of mood disorders. Hypothalamic neuropeptides are thought to be biomarkers used to differentiate patients with mood disorders. In our study, we aimed to evaluate the concentrations of hypothalamic neuropeptides NPY and POMC in patients with bipolar (BP) and unipolar (UP) depression.
methodsThe study included 26 UP and 28 BP patients, 27 healthy controls.NPY and POMC concentrations were quantified in peripheral blood specimens.The Hamilton Depression Rating Scale(HAM-D), Epworth Sleepiness Scale and Three-Factor Eating Questionnaire were administered.
resultsSerum NPY and POMC levels were significantly lower in UP and BP patients compared to the control group (p = 0.001).NPY level was lower in the depression group compared to the bipolar group but not statistically significant (p˃0.05).POMC level was decreased in the bipolar group compared to the depression group, but the results were not statistically significant (p˃0.05). No significant correlation was found between any scale score and NPY and POMC(p>0.05).
conclusionThis study suggests that changes in serum NPY and POMC levels in UP and BP patients may have a potential role in disease pathophysiology. In particular, it is the first study to investigate the interaction between NPY, POMC and changes in eating behaviour in depressed patients, highlighting the need for further research in this area.
