Protective Effect of Biobran/MGN-3, an Arabinoxylan from Rice Bran, Against the Cytotoxic Effects of Polyethylene Nanoplastics in Normal Mouse Hepatocytes: An In Vitro and In Silico Study.
Article in Nutrients, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundPlastic is one of the most versatile and widely used materials, but the environmental accumulation of nanoplastics (NPs) poses a risk to human health. Preclinical studies have verified that the liver is one of the main organs susceptible to NPs. Biobran/MGN-3, an arabinoxylan from rice bran, has been shown to have hepatoprotective effects; here, we show Biobran's ability to alleviate polyethylene nanoplastics (PE-NPs)-induced liver cell toxicity by reversing apoptosis and restoring G2/M cell arrest in mouse liver cells (BNL CL.2).
methodsToxicological effects were measured using the sulforhodamine B (SRB) assay for cell viability and flow cytometry for cell cycle analysis and apoptosis. An in silico study was also used to demonstrate the docking of PE-NPs to pro-inflammatory mediator proteins (IL-6R, IL-17R, CD41/CD61, CD47/SIRP), cell cycle regulators (BCL-2, c-Myc), as well as serine carboxypeptidase, which is an active ingredient of Biobran.
resultsExposing liver cells to PE-NPs caused a significant decrease in cell viability, with an IC50 value of 334.9 ± 2.7 µg/mL. Co-treatment with Biobran restored cell viability to normal levels, preserving 85% viability at the highest concentration of PE-NPs. Additionally, total cell death observed after exposure to PE-NPs was reduced by 2.4-fold with Biobran co-treatment. The G2/M arrest and subsequent cell death (pre-G0 phase) induced by PE-NPs were normalized after combined treatment. The in silico study revealed that Biobran blocks the nucleophilic centers of PE-NPs, preventing their interaction with pro-inflammatory mediators and cell cycle regulators.
conclusionsThese findings highlight the potential use of Biobran as a hepatoprotector against NP toxicity.
