Aberrant overexpression of m6A writer and reader genes in pediatric B-Cell Acute Lymphoblastic Leukemia (B-ALL).
Article in Translational oncology, 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
backgroundm6A modification, regulated by writers (METTL3, METTL14), erasers (ALKBH5, FTO), and readers (IGF2BPs), is implicated in various cancers, including leukemias.
methodsIn our study, we examined a cohort of 227 pediatric B-ALL patients (152 primary and 75 relapsed) and assessed the expression profiles of m6A machinery genes, including both writers and erasers, as well as the IGF2BP RNA-binding proteins, which are known as m6A readers. We also quantified the absolute percentage of m6A (m6A%). The correlation between m6A machinery gene expression and patient prognosis was studied using univariate and multivariate analyses.
resultsOur analysis revealed a significant upregulation of m6A writers (METTL3 and METTL14), erasers (FTO), and m6A readers (IGF2BPs 1 and 3) in B-ALL patients, both in the primary and relapsed groups. m6A% levels were markedly higher in B-ALL samples than in controls. Multivariate analysis revealed that the expression of IGF2BP3, METTL3, and FTO genes, independently predicted lower overall survival and event-free survival in primary B-ALL patients.
conclusionsDespite the collective dysregulation of the m6A machinery, the writers and readers appear to have a more dominant phenotype, as evidenced by the significantly elevated m6A% levels. This is the first study to analyze and establish the role of m6A machinery gene expression and its correlation with survival outcomes in a large group of B-ALL patients. These findings could aid in the development of new therapeutics targeting the m6A machinery and help predict relapse in pediatric B-ALL patients.
