MicroRNA-541-3p/Rac2 signaling bridges radiation-induced lung injury and repair.
Article in Non-coding RNA research, 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
Background: While radiation-induced lung injury decreases quality of life and suppresses efficacy of radiotherapy, to date, the relationship between radiation-induced lung injury and repair remains unclear. Our previous studies revealed that TNFRSF10B-RIPK1/RIPK3-MLKL signaling induces necroptosis of alveolar epithelial cells and potentiates radiation-induced lung injury. We also found that microRNA-541-3p is differentially expressed in radiation-damaged lungs. The connection between microRNA-541-3p, TNFRSF10B signaling, and TGFβ1 signaling is also unclear. Objective: This study was performed to explore the regulatory effects of microRNA-541-3p on TNFRSF10B and TGFβ1 signaling. Methods: Mouse alveolar epithelial cells were transfected with a vector expressing microRNA-541-3p to regulate expression of target genes. Flow cytometry, polymerase chain reaction, and western blotting were used to analyze cell necroptosis, target gene expression, and target protein expression, respectively. Results: Overexpression of microRNA-541-3p positively regulated TNFRSF10B-RIPK1/RIPK3-MLKL signaling through Rac2 to induce cell necroptosis. MicroRNA-541-3p negatively regulates Rac2. MicroRNA-541-3p and Rac2 regulate the expression of Tgf-beta1 and its encoded proteins. Conclusions: The Rac2 gene synchronously regulates TNFRSF10B-RIPK1/RIPK3-MLKL and TGFβ1 signaling. MicroRNA-541-3P/Rac2 act as mediators of radiation damage and repair signaling.
