Fam172a Mediates the Stimulation of Hypothalamic Oxytocin Neurons to Suppress Obesity-Induced Anxiety.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Anxiety disorder is the most common mental disorder worldwide. Although human studies have demonstrated a positive association between obesity and anxiety disorder, the exact mechanism linking these conditions is unclear. Interestingly, oxytocin (Oxt) neurons, predominantly expressed in the hypothalamic paraventricular nucleus (PVN), play a crucial role in both obesity and anxiety. In this study, obesity can induce anxiety-like behavior in mice, which can be ameliorated by the activation of PVN Oxt neurons. Conversely, inhibiting PVN Oxt neurons accelerate the progression of anxiety. Moreover, the family with sequence similarity 172, member A (Fam172a), an anxiety susceptibility gene, is highly expressed in the hypothalamic PVN Oxt neuron but reduce in the PVN Oxt neuron of mice in the high-fat diet and acute restraint stress conditions. Significantly, overexpression of Fam172a in PVN Oxt neurons improve obesity-anxiety-like behavior in mice. In contrast, disruption of Fam172a in PVN Oxt neurons exacerbate obesity-anxiety-like behavior. Furthermore, this study demonstrates that Fam172a is involved in mRNA degradation in Oxt neurons by regulating the intranuclear transport of Argonaute 2, thereby influencing Oxt secretion and ultimately impacting obesity-anxiety-like behavior. These findings suggest that Fam172a serves as a key target of PVN Oxt neurons in the regulation of obesity-induced anxiety.
