Jagged1 intracellular domain modulates steroidogenesis in testicular Leydig cells.
Article in PloS one, 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
Leydig cells represent the steroidogenic lineage of mammalian testis, which produces testosterone. Genetic evidence indicates the requirement of Notch signaling in maintaining a balance between differentiated Leydig cells and their progenitors during fetal development. In primary Leydig cells, Notch1 expression decreases with testicular development, while the expression of its ligand, Jagged1, remains relatively unchanged, suggesting that the roles of Jagged1 extend beyond Notch signaling. In addition, Jagged1 is known to be processed into its intracellular domain, which then translocate to the nucleus. In this study, we investigated the effect of Jagged1 intracellular domain (JICD) on steroidogenesis in Leydig cells. The independent overexpression of JICD in MA-10 Leydig cells was found to inhibit the activity of cAMP-induced Nur77 promoter. In addition, JICD suppressed Nur77 transactivation of the promoter of steroidogenic genes such as P450scc, P450c17, StAR, and 3β-HSD. Further, adenovirus-mediated overexpression of JICD in primary Leydig cells repressed the expression of steroidogenic genes, consequently lowering testosterone production. These results collectively suggest that steroidogenesis in testicular Leydig cells, which is regulated by LH/cAMP signaling, is fine-tuned by Jagged1 during testis development.
