Activin A rescues preterm brain injury through a novel Noggin/BMP4/Id2 signaling pathway.
Article in International journal of molecular medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Activin A (Act A) has been reported to promote oligodendrocyte progenitor cell (OPC) differentiation in vitro and improve neurological outcomes in adult mice. However, the roles and mechanisms of action of Act A in preterm brain injury are unknown. In the present study, P5 rats were subjected to hypoxia‑ischemia to establish a neonatal white matter injury (WMI) model and Act A was injected via the lateral ventricle. Pathological characteristics, OPC differentiation, myelination, and neurological performance were analyzed. Further, the involvement of the Noggin/BMP4/Id2 signaling pathway in the roles of Act A in WMI was explored. Act A attenuated pathological damage, promoted OPC differentiation, enhanced myelin sheath and myelinated axon formation, and improved neurological performance of WMI rats. Moreover, Act A enhanced noggin expression, which, in turn, inhibited the expression of bone morphogenetic protein 4 (BMP4) and inhibitor of DNA binding 2 (Id2). Furthermore, upregulation of Id2 completely abolished the rescue effects of Act A in WMI rats. In conclusion, the present findings suggested that Act A rescues preterm brain injury via targeting a novel Noggin/BMP4/Id2 signaling pathway.
