A Phenotypic High-Throughput Screen Identifies Small Molecule Modulators of Endogenous RGS10 in BV-2 Cells.
Article in Journal of medicinal chemistry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Chronic dysregulation of microglial phenotypic balance contributes to prolonged neuroinflammation and neurotoxicity, which is a hallmark of neurodegenerative diseases. Thus, targeting microglial inflammatory signaling represents a promising therapeutic strategy for neurodegenerative diseases. Regulator of G protein Signaling 10 (RGS10) is highly expressed in microglia, where it suppresses pro-inflammatory signaling. However, RGS10 is silenced following microglial activation, augmenting inflammatory responses. While modulating RGS10 expression is a promising strategy to suppress pro-inflammatory microglial activation, no chemical tools with this ability exist. We developed a phenotypic high-throughput assay to screen for compounds with the ability to reverse interferon-γ (IFNγ)-induced RGS10 silencing in BV-2 cells. Identified hits had no effect on RGS10 expression in the absence of stimulus or in response to lipopolysaccharide (LPS). Furthermore, the hits reversed some of the inflammatory gene expression induced by IFNγ. This is the first demonstration of the potential for small molecule intervention to modulate the RGS10 expression in microglia.
