Bioinformatics insights into ACSL1 and ACSL5: prognostic and immune roles in low-grade glioma.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundFatty acid metabolism disruptions affect low-grade gliomas (LGGs), with glioma cells depending on fatty acids for survival. Targeting fatty acid oxidation through the acyl-coenzyme A synthetase long-chain (ACSL) family could alleviate glioma growth and improve prognosis management. However, the integration of ACSLs for analyzing their relationship with LGGs remains unexplored.
methodsWe collected RNA expression data of ACSLs for LGGs from TCGA, GTEx, CGGA, and GEO datasets and validated the prognostic significance of gene expression in 37 glioma samples. DNA methylation data from UCSC Xena and promoter methylation levels via MEXPRESS were analyzed. Functional enrichments of co-expressed ACSLs genes were conducted using Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and Gene Set Enrichment Analysis. Protein-protein interaction networks were established via GeneMANIA, and cBioPortal assessed somatic mutations and copy number variations of ACSLs in LGGs. TIMER and TISIDB databases investigated the correlation between ACSLs expression and immune infiltration and checkpoint genes. Hazard ratios (HR) with 95% confidence intervals (95% CI) were computed, and net reclassification index and integrated discrimination improvement were estimated to evaluate the predictive capability of the prognosis model.
resultsIndependent prognostic factors for overall survival included age, gender, tumor grade, MGMT promoter status, ACSL1, ACSL3, ACSL5, and ACSL6 expression levels. High ACSL1 (HR = 2.352, 95%CI: 1.647-3.359, P = 9.00E-06), ACSL3 (HR = 2.367, 95%CI: 1.547-3.624, P = 2.92E-04) and ACSL5 (HR = 2.329, 95%CI: 1.611-3.367, P = 2.80E-05) expression correlated with poor prognosis, while increased ACSL6 (HR = 0.449, 95%CI: 0.290-0.696, P = 1.02E-03) expression related to better survival rates. Furthermore, these associations were also confirmed in the validation datasets and our external cohort. Negative correlation between ACSL1 and ACSL3 gene expression and methylation was found. Functional enrichment analyses highlighted the roles of ACSL1 and ACSL5 in glioma mechanisms and immune function, with significant associations between somatic CNVs and immune cell infiltration.
conclusionsACSL1 and ACSL5 exhibit prognostic significance in gliomas and influence tumor immunity and immune cell migration, providing valuable insights into LGG prognosis and therapeutic targets.
