1 · What the graph read from it

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.

2 · The registry

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

backgroundLong non-coding RNA (lncRNA) DLEU1 has been implicated in tumorigenesis, yet its mechanistic role in gastric cancer (GC) remains elusive.

methodsWe investigated the epigenetic regulation and oncogenic function of DLEU1 in GC through chromatin immunoprecipitation, RNA-protein interaction assays, and functional analyses in organoids and xenograft models. The molecular mechanisms underlying DLEU1-mediated DNA repair and metabolic adaptation were elucidated using western blotting, quantitative RT-PCR, and luciferase reporter assays.

resultsDLEU1 was significantly upregulated in GC, driven by H3K27 acetylation and H3K4 methylation. Mechanistically, DLEU1 promoted DNA repair by facilitating ASCC2 nuclear translocation and its interaction with ALKBH3, thereby stabilizing E2F1 mRNA. In turn, E2F1 directly activated G6PD transcription, leading to enhanced NADPH production, redox homeostasis, and glucose metabolism. Functionally, co-targeting DLEU1 and ASCC2 synergized with G6PD inhibition, significantly impairing GC cells viability and tumor growth.

conclusionOur findings establish DLEU1 as a key oncogenic lncRNA in GC, orchestrating DNA repair, redox balance, and metabolic adaptation via the ASCC2-ALKBH3-E2F1-G6PD axis. Targeting this pathway may provide a promising therapeutic strategy for overcome GC chemoresistance.
