The Effects of Atoh8 on Postnatal Murine Neurogenesis.
Article in Cells, tissues, organs, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
introductionBasic helix-loop-helix (bHLH) transcription factors are expressed in various organs and are involved in diverse developmental processes. The mouse atonal homolog 8 (Atoh8), a bHLH transcription factor, plays a crucial role in various developmental processes, especially as a regulator of neurogenesis in the retina. Besides, Atoh8 expression has been observed in the central nervous system. The function of Atoh8 during the postnatal neurogenesis is still unclear.
methodsThis study focuses on elucidating the impact of Atoh8 on postnatal neurogenesis in the brain, particularly in selected regions: the subventricular zone (SVZ), rostral migratory stream (RMS), and olfactory bulb (OB), across different life stages, using male homozygous Atoh8-knockout (M6KO) mice. Our morphometric analysis is based on immunohistochemically labeled markers for neuroblasts (doublecortin) and proliferation (phospho-histone H3, PHH3) as well as pan neuronal markers.
resultsIn Atoh8-/- mice, alteration in the postnatal neurogenesis can be observed. Immunohistochemical analysis revealed a significant reduction in doublecortin-positive neuroblasts within the SVZ of neonatal M6KO mice compared to wild-type mice. Interestingly, no differences in cell number and distribution were observed in the subsequent migration of neuroblasts through the RMS to the OB. Proliferating PHH3-positive neuronal progenitor cells were significantly diminished in the proliferation rate in both the SVZ and RMS of neonatal and young M6KO mice. Furthermore, in the glomerular layer of the OB, significantly fewer neurons were detected in the neonatal stage.
conclusionIn conclusion, Atoh8 emerges as a positive regulator of postnatal neurogenesis in the brain. Its role encompasses the promotion of neuroblast formation, modulation of proliferation rates, differentiation, and maintenance of mature neurons. Understanding the intricacies of Atoh8 function provides valuable insights into the complex regulatory mechanisms governing neurogenesis.
