LncRNA CYP1B1-AS1 as a clinical biomarker exacerbates sepsis inflammatory response via targeting miR- 18a- 5p.
Article in BMC immunology, 2025. 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
backgroundSepsis, characterized by high morbidity and mortality, necessitates the identification of novel diagnostic and prognostic biomarkers to enhance patient outcomes. Prior research has highlighted the potential clinical utility of long non-coding RNAs (lncRNAs) in sepsis. This study aimed to investigate the clinical significance and underlying mechanisms of serum lncRNA Cytochrome P450 family 1 subfamily B member 1 antisense RNA 1 (CYP1B1-AS1) expression in sepsis.
methodsDifferentially expressed lncRNAs in sepsis patients were explored via GEO database. Sepsis patients and Control subjects were included. An in vitro cellular model was established with LPS-stimulated THP- 1 cells. RT-qPCR assessed CYP1B1-AS1 and miR- 18a- 5p expression. ROC analysis evaluated diagnostic and predictive value. Kaplan-Meier curves and Cox regression analyzed the prognostic value of CYP1B1-AS1. Flow cytometry and ELISA assessed cell apoptosis and inflammatory factors levels. Dual luciferase reporter, RIP, and RNA pull down to validate target binding relationship.
resultsThe GSE217700 database shows that CYP1B1-AS1 was upregulated in sepsis. Serum levels of CYP1B1-AS1 were higher in sepsis patients than controls. CYP1B1-AS1 was positively correlated with SOFA and APACHE II scores and distinguished sepsis patients from controls. The 28-day mortality rate for sepsis patients was 29.31%. High CYP1B1-AS1 expression in sepsis patients predicts a worse prognosis and is a potential risk factor. CYP1B1-AS1 targets miR- 18a- 5p. Silencing CYP1B1-AS1 reduced LPS-inducted apoptosis and inflammatory factor promotion, which the miR- 18a- 5p inhibitor reversed.
conclusionCYP1B1-AS1 serves as a biomarker for sepsis diagnosis and poor prognosis, potentially promoting inflammation and apoptosis by targeting miR- 18a- 5p.
