Expression patterns of GPX4 and LINC00618 across disease phases in pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL): an exploratory study.
Article in BMC cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAcute lymphoblastic leukemia (ALL) remains a significant challenge in pediatric malignancies, particularly in cases of relapse and treatment resistance. This study aimed to investigate the expression patterns of ferroptosis-related genes, GPX4 and LINC00618, across different disease phases in pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL).
methodsThis case-control study analyzed 82 samples from pediatric BCP-ALL patients comprising 14 new cases, 29 in remission, and 17 relapsed cases alongside 22 healthy controls. Expression levels of GPX4 and LINC00618 were evaluated using quantitative real-time PCR. The relationship between gene expression and clinical parameters was assessed. Statistical analyses were performed employing parametric or nonparametric tests.
resultsGPX4 expression was significantly elevated in ALL patients compared to controls (p < 0.01), with notably higher levels in new cases (p < 0.01) and relapsed patients (p < 0.05). Similarly, LINC00618 exhibited significant upregulation in ALL patients (p < 0.05), particularly in new cases (p < 0.01) and relapsed patients (p < 0.05). Both genes demonstrated reduced expression during the remission. External validation using the GSE13159 dataset demonstrated a consistent direction of increased GPX4 expression in ALL samples compared to controls.
conclusionsOur findings suggest phase-associated expression patterns of GPX4 and LINC00618 in pediatric BCP-ALL. The consistent direction of GPX4 expression observed in external validation supports its potential relevance in leukemic biology. These results provide a basis for further studies to clarify the role of ferroptosis-related pathways in disease progression and therapeutic response.
