Human long non-coding RNAs acquired from bacteria via horizontal gene transfer promote gallbladder cancer.
Article in Molecular biology reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundGallbladder cancer, the most common malignancy of the bile duct, has a poorly understood etiopathogenesis. Non-coding RNAs are implicated in various cancers, but their role in gallbladder carcinogenesis remains unclear.
methodsTranscriptomic data from gallbladder cancer patients were analyzed to identify differentially expressed long non-coding RNAs (lncRNAs). These data underwent cross-species phylogenetic analysis and BLAST comparison with bacterial and ancient human genomes, including Homo heidelbergensis and Homo neanderthalensis. Pathway analysis, gene-gene interactions, and data and text mining were performed for non-conserved, non-coding genes.
resultsOf 16 differentially expressed lncRNAs, seven showed phylogenetic links to bacterial genomes, suggesting acquisition through horizontal gene transfer (HGT) during human evolution. These lncRNAs were present in ancient human species with sequence variations. Functional analysis revealed their role in regulating biological and genetic processes, potentially promoting gallbladder carcinogenesis.
conclusionsThis is the first study to propose that seven human lncRNAs, likely of bacterial origin, were acquired through HGT during evolution. These lncRNAs regulate transcriptional and post-transcriptional processes, potentially inducing gallbladder carcinogenesis, thus highlighting a novel link between evolutionary genetics and cancer.
