Transcriptome Changes in Retinal Pigment Epithelium Post-PNU-282987 Treatment Associated with Adult Retinal Neurogenesis in Mice.
Article in Journal of molecular neuroscience : MN, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
PNU-282987, a selective alpha7 nicotinic acetylcholine receptor agonist, has previously been shown to have both neurogenic and broad regenerative effects in the adult murine retina. The objective of this study was to assay the molecular mechanism by which PNU-282987 promotes the production of Muller-derived progenitor cells through signaling via the resident retinal pigment epithelium. These Muller-derived progenitor cells generate a myriad of differentiated neurons throughout the retina that have previously been characterized by morphology. Herein, we demonstrate that topical application of PNU-282987 stimulates production of functional neurons as measured by electroretinograms. Further, we examine the mechanism of how this phenomenon occurs through activation of this atypical receptor using a transcriptomic approach isolated retinal pigment epithelium activated by PNU-282987 and in whole retina. We provide evidence that PNU-282987 causes a bi-modal signaling event in which early activation primes the retina with an inflammatory response and developmental signaling cues, followed by an inhibition of gliotic mechanisms and a decrease in the immune response, ending with upregulation of genes associated with specific retinal neuron generation. Taken together, these data provide evidence that PNU-282987 activates the retinal pigment epithelium to signal to Muller glia to produce Muller-derived progenitor cells, which can differentiate into new, functional neurons in adult mice. These data not only increase our understanding of how adult mammalian retinal regeneration can occur, but also provide therapeutic promise for treating functional vision loss.
