Comprehensive transcriptome sequencing and biochemical studies revealed that acrolein induced lung injury in BEAS-2B cells and male rats through the lncRNA MIR155HG/miR-155-5p/CD200R1 and Nrf2/SLC7A11/GPX4 ferroptosis pathways.

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
Acrolein is a significant high priority hazardous air pollutant. This research explore the relationship of acrolein-induced ferroptosis with the pathogenesis of lung injury by combining cellular, transcriptome, and animal-level studies. The results in vivo and in vitro models indicated that a total of 18,868 differenced lncRNAs and 15,639 differenced mRNAs were obtained after acrolein exposure. After screening, 636 lncRNAs and 214 mRNAs were obviously different of the acrolein injured group with the control group. Differential genes were mainly enriched in the iron ion binding, tissue homeostasis, etc. Among them, lncRNA MIR155HG significantly responded to the toxic effects of acrolein, the knockdown of lncRNA MIR155HG could inhibit miR-155-5p expression, promote CD200R1 expression, and improve cell viability. Furthermore, it effectively inhibited acrolein-induced the activation of ferroptosis pathway in BEAS-2B cells and lung tissue, indicating that lncRNA MIR155HG might be a potential new target for the inhibition of acrolein toxicity. LncRNA-MIR155HG/miR-155-5p/CD200R1 axis played an significant role in the lung injury, and induced ferroptosis by regulating the Nrf2/SLC7A11/GPX4 pathway. This study is the first to reveal that acrolein exposure significantly affected lncRNA and mRNA expression in BEAS-2B cells, and found that lncRNA MIR155HG effectively regulated acrolein-induced ferroptosis pathway, providing novel insights for the treatment of lung injury.
