Peroxiredoxin 6 Protects Pulmonary Epithelial Cells From Cigarette-related Ferroptosis in Chronic Obstructive Pulmonary Disease.

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
Peroxiredoxin 6 (PRDX6) has a protective effect on pulmonary epithelial cells against cigarette smoke (CS)-induced ferroptosis. This study investigates the role of PRDX6 in the development of chronic obstructive pulmonary disease (COPD) and its possibility as a target. We observed that PRDX6 was downregulated in lung tissues of COPD patients and in CS-stimulated cells. The degradation of PRDX6 could be through the lysosomal pathway. PRDX6 deficiency exacerbated pulmonary inflammation and mucus hypersecretion in vivo. Overexpression of PRDX6 in Beas-2B cells ameliorated CS-induced cell death and inflammation, suggesting its protective role against CS-induced damage. Furthermore, PRDX6 deficiency promoted ferroptosis by adding the content of iron and reactive oxygen species, while iron chelation with deferoxamine mitigated CS-induced ferroptosis, cell death, and inflammatory infiltration both in vitro and in vivo. The critical role of PRDX6 in regulating ferroptosis suggests that targeting PRDX6 or iron metabolism may represent a promising strategy for COPD treatment.
