Acute cigarette smoke-induced eQTL affects formyl peptide receptor expression and lung function.
Article in Respirology (Carlton, Vic.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 AND
objectiveCigarette smoking is one of the most prevalent causes of preventable deaths worldwide, leading to chronic diseases, including chronic obstructive pulmonary disease (COPD). Cigarette smoke is known to induce significant transcriptional modifications throughout the respiratory tract. However, it is largely unknown how genetic profiles influence the smoking-related transcriptional changes and how changes in gene expression translate into altered alveolar epithelial repair responses.
methodsWe performed a candidate-based acute cigarette smoke-induced eQTL study, investigating the association between SNP and differential gene expression of FPR family members in bronchial epithelial cells isolated 24 h after smoking and after 48 h without smoking. The effects FPR1 on lung epithelial integrity and repair upon damage in the presence and absence of cigarette smoke were studied in CRISPR-Cas9-generated lung epithelial knockout cells.
resultsOne significant (FDR < 0.05) inducible eQTL (rs3212855) was identified that induced a >2-fold change in gene expression. The minor allele of rs3212855 was associated with significantly higher gene expression of FPR1, FPR2 and FPR3 upon smoking. Importantly, the minor allele of rs3212855 was also associated with lower lung function. Alveolar epithelial FPR1 knockout cells were protected against CSE-induced reduction in repair capacity upon wounding.
conclusionWe identified a novel smoking-related inducible eQTL that is associated with a smoke-induced increase in the expression of FPR1, FPR2 and FPR3, and with lowered lung function. in vitro FPR1 down-regulation protects against smoke-induced reduction in lung epithelial repair.
