NR4A1 Exerts Pro-Tumor Role in Glioblastoma via Inducing xCT/GPX4-Regulated Ferroptosis.
Article in Annals of clinical and translational neurology, 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
purposeThis study investigates NR4A1's paradoxical roles in glioblastoma (GBM) progression, focusing on its mechanistic link to ferroptosis regulation. We aimed to resolve conflicting reports of NR4A1 as both an oncogene and a tumor suppressor by defining its transcriptional control over xCT/GPX4-mediated iron homeostasis and its clinical relevance in glioma survival.
methodsTCGA cohort analysis (n = 163) correlated NR4A1 expression with survival endpoints (OS/PFI/DSS, log-rank p < 0.05). Functional validation employed U87/U251 GBM models for viability (CCK-8), proliferation (EdU/colony formation), and migration assays (Transwell/wound healing). RNA sequencing (DESeq2, FDR < 0.05) and ChIP-qPCR identified NR4A1-xCT transcriptional regulation. Ferroptosis was quantified via lipid peroxidation (MDA/GSH/Fe
conclusionNR4A1 drives GBM progression by transcriptionally activating xCT/GPX4 to suppress ferroptosis. Dual targeting of NR4A1 and ferroptosis pathways synergistically inhibits tumor growth (64% reduction vs. controls, p = 0.008), providing a mechanistic rationale for overcoming therapy resistance in GBM.
