Gallic acid's protective mechanisms against acrylamide-induced pulmonary injury: in vivo and in silico insights into the Nrf-2/HO-1/NFκB pathway modulation.

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
Acrylamide (ACR) is a toxic compound formed during the heating of tobacco and starchy foods, contributing to increased reactive oxygen species (ROS) levels and significant health risks. This study evaluates the protective effects of gallic acid (GA), a natural polyphenol with potent antioxidant and anti-inflammatory properties, against ACR-induced lung injury. Fifty male rats were divided into five groups: Control, ACR, GA50 + ACR, GA100 + ACR, and GA100. Lung tissues were analyzed biochemically, histopathologically, immunohistochemically, and via immunofluorescence. GA exhibited dose-dependent protective effects by enhancing antioxidant defenses through Nrf-2 (43% increase) and HO-1 activation and reducing lipid peroxidation markers (MDA decreased by 38%). GA also suppressed pro-inflammatory mediators (TNF-α reduced by 35%) and restored anti-inflammatory levels by modulating the NF-κB pathway. Furthermore, GA reduced apoptosis (Caspase-3 activity decreased by 30%) and preserved lung tissue integrity by mitigating oxidative DNA damage (8-OHdG levels reduced by 29%) and pro-apoptotic signaling (Bax levels reduced by 34%). Computational analyses demonstrated GA's interaction with the KEAP1 protein, supporting its role in activating the KEAP1-Nrf2 pathway. These findings highlight GA's antioxidant, anti-inflammatory, and anti-apoptotic properties, suggesting its therapeutic potential for protecting against ACR-induced lung injury and paving the way for future research in lung health and toxicology.
