Metrnl regulates cognitive dysfunction and hippocampal BDNF levels in D-galactose-induced aging mice.

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
Aging is one of the main risk factors for cognitive dysfunction. During aging process, the decrease of brain-derived neurotrophic factor (BDNF) and the impairment of astrocyte function contribute to the cognitive impairment. Metrnl, a neurotrophic factor, promotes neural growth, migration and survival, and supports neural function. In this study, we investigated the role of Metrnl in cognitive functions. D-galactose (D-gal)-induced aging model was used to simulate the process of aging. Cognitive impairment was assessed by the Morris water maze test. We showed that Metrnl expression levels were significantly increased in the hippocampus of D-gal-induced aging mice. Metrnl knockout did not affect the cognitive functions in the baseline state, but aggravated the cognitive impairment in the D-gal-induced aging mice. Furthermore, Metrnl knockout significantly reduced hippocampal BDNF, TrkB, and glial fibrillary acidic protein (GFAP) levels in the D-gal-induced aging mice. In the D-gal-induced aging cell model in vitro, Metrnl levels in the hippocampal astrocytes were significantly increased, and Metrnl knockdown and overexpression regulated the BDNF levels in primary hippocampal astrocytes rather than in neurons. We conclude that Metrnl regulates cognitive functions and hippocampal BDNF levels during aging process. As a neurotrophic factor and an endogenous protein, Metrnl is expected to become a new candidate for the treatment or alleviation of aging-related cognitive dysfunction.
