Early growth response 1 as a key regulator of PD-L1 expression and immune evasion in extranodal NK/T-cell lymphoma.
Article in Blood cancer journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This study investigates the role of Early Growth Response 1 (EGR1) in extranodal natural killer/T-cell lymphoma (ENKTL) and its correlation with PD-L1 expression. Analysis of 62 ENKTL patient samples revealed that high EGR1 expression was linked to PD-L1 positivity, the immune evasion-A subtype, and early-stage disease. Although EGR1 expression was not an independent prognostic factor for overall survival, patients with higher EGR1 levels showed a trend toward better outcomes. In ENKTL cell lines (YT, SNK6), EGR1 positively regulated LMP1 and PD-L1 expression. Knockdown of EGR1 reduced PD-L1 levels, decreased PTEN, increased AKT phosphorylation, and abrogated STAT3 phosphorylation. Conversely, EGR1 overexpression enhanced PD-L1. Treatment with the histone deacetylase inhibitor entinostat upregulated both EGR1 and PD-L1, but this effect was lost in EGR1-depleted cells, indicating EGR1's necessity for HDAC inhibitor-induced PD-L1 expression. These findings reveal EGR1's pivotal role in tumor immune modulation and highlight potential combination therapies targeting EGR1, epigenetic regulators, and PD-1/PD-L1 checkpoints.
