mRNA and microRNA Profiles in the Amygdala Are Relevant to Susceptibility and Resilience to Psychological Stress Induced in Mice.
Article in Journal of molecular neuroscience : MN, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Severe or prolonged stress increases the risk for developing psychopathological disorders. An individual's perception of stress exposure varies greatly, as do its consequences. Numerous individuals demonstrate resilience to psychological stress. The mRNA and microRNA profiles of stress susceptibility and resilience to induced psychological stress in the amygdala remain to be elucidated. In this work, psychological stress was induced in an observer mouse by witnessing a similar individual under attack by an aggressor. After 5 days of psychological stress, the degree of fear memory and anxiety in mice was measured by a social interaction test and elevated plus-maze (EPM) test. mRNA and microRNA profiles were quantified by high-throughput sequencing in amygdala tissue harvested from Control, Susceptible and Resilient mice. In the amygdala of Susceptible versus Resilient mice, the upregulation of peptide, thyrotropin-releasing hormone, ECM receptors, glutamatergic synapse, cytokine-cytokine receptor interaction, long-term depression, PI3K-Akt, oxytocin, GnRH, HIF-1, estrogen, and calcium signaling pathways may be related to psychological stress-induced susceptibility, and their downregulation may be related to resilience. The downregulation of adrenergic synapse, adherens junction, Wnt, sphingolipid, B cell receptor, cAMP, Rap1, and Toll-like receptor signaling pathways may be related to psychological stress-induced susceptibility, and the upregulation may be related to resilience. Results by sequencing of mRNA and microRNA profiles are consistent, in which some are validated by qRT-PCR and dual-luciferase reporter assay. Susceptibility and resilience induced by psychological stresses are caused by the imbalanced regulation of different synapses and signaling pathways in the amygdala.
