The Change of Noncoding RNA Expression in Olfactory Bulb of Hepatic Encephalopathy Mouse Model: Transcriptomic Analysis and Cellular Analysis.
Article in CNS neuroscience & therapeutics, 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
objectivesHepatic encephalopathy (HE) is a neuropsychiatric disorder associated with cirrhosis and chronic liver disease primarily driven by ammonia (NH3) toxicity, which leads to neuroinflammation and cognitive deficits. Recent studies have identified olfactory dysfunction as a potential early indicator of HE, linked to ammonia-induced neurotoxicity in the brain.
methodsAfter confirming physiological alterations in olfactory cells induced by ammonia, we assessed gene expression changes in olfactory bulbs of bile duct ligation (BDL) mice as an HE mouse model. We systematically profiled diverse coding and noncoding RNAs (ncRNAs) associated with olfactory dysfunction in HE and analyzed the functional implications based on transcriptomic signatures. We also compared ammonia toxicity effects between the olfactory bulb and cerebral cortex in this animal model.
resultsFurthermore, we investigated the differential impacts on the olfactory bulb between HE and high-fat diet-induced models, two major paradigms of metabolic imbalance. We identified key RNAs commonly altered between the olfactory bulb and cerebral cortex of the HE model, as well as in olfactory bulbs across BDL and high-fat diet models.
conclusionsOur results provide a transcriptomic resource for understanding the molecular landscape of HE-related olfactory dysfunction and may inform future studies aimed at functional validation and therapeutic exploration.
