Arsenic unsettles the cerebellar balance between neurodegeneration and neurogenesis: reversal by folic acid.

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
Arsenic-mediated neurodegenerative disorders affect millions of individuals globally, but the specific impact of environmental arsenic on adult cerebellar degeneration and neurogenesis is incompletely understood. Of particular concern is arsenic-induced apoptosis-driven neurodegeneration. Our major objective was to investigate the molecular signaling intricacies associated with arsenic-induced death of cerebellar neurons and to propose folic acid as a possible intervention. Swiss albino mice were treated with sodium arsenite (orally: 0.05 mg/L) and folic acid (orally:10 mg/kg) for 28 days. We observed that arsenic caused noticeable cell loss with morphological alterations in cerebellum, which was remarkably restored by folic acid. Arsenic-induced morphological alterations consequently perturbed transcriptional activities of neural stem cell factors-SOX2 and KLF9, which resulted in the suppression of pro-neurogenic mediators NeuroD1, Neurogenin2, calbindin and NeuN. Interestingly, folic acid reversed the expression of these critical pro-neurogenic mediators to mitigate these degenerative changes to promote neurogenesis. Delving deep, we found that folic acid rescued arsenic-exposed cerebellum from severe oxidative and pro-inflammatory insults by increasing antioxidants like SOD, Catalase, GSH, upregulating Nrf2 and downregulating M1 macrophages, JNK, NF-κB, and STAT3 activities. For the first time, we are reporting that arsenic induced a G1/S cell cycle arrest and triggered apoptosis in mouse cerebellum by activating the p53-p21 axis, downregulating CDKs and instigated p21-mediated suppression of SOX2 transcriptional activity. Folic acid abated such alterations by modulating the p53/p21/SOX2 axis. Collectively, the anti-apoptotic and pro-neurogenic effects of folic acid present it as a promising therapeutic candidate, warranting further research into its efficacy against metal-induced neurodegenerative disorders.
