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

backgroundHistone methyltransferases are crucial regulators in non-small cell lung cancer (NSCLC) development. This study explored the mechanism of histone methyltransferase SET domain containing 1A (SETD1A)-mediated H3K4me2 methylation in NSCLC cell ferroptosis and provides novel targets for NSCLC treatment.

methodsUpon downregulation of SETD1A in NSCLC cell lines, cell proliferation potential, malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) activities, iron content, and SETD1A, long noncoding RNA HOXC cluster antisense RNA 3 (lncRNA HOXC-AS3), E1A binding protein p300 (EP300), glutathione peroxidase 4 (GPX4) expressions were determined via cell counting kit-8, ELISA, iron assay kits, RT-qPCR, and western blot. Enrichment levels of SETD1A and H3K4me3 in the HOXC-AS3 promotor were measured via chromatin immunoprecipitation, and the binding of HOXC-AS3 and EP300 was analyzed via RNA immunoprecipitation. Rescue experiments were performed to confirm their roles in NSCLC cell ferroptosis. Xenograft tumor models were established to validate the role of SETD1A in vivo.

resultsSETD1A, H3K4me3, HOXC-AS3, and EP300 were highly-expressed in NSCLC cells. Silencing SETD1A inhibited NSCLC cell proliferation, increased MDA and iron levels, and decreased SOD, GSH, and GPX4 levels. SETD1A downregulation reduced H3K4me3 level, HOXC-AS3 expression, the binding of HOXC-AS3 to EP300, and EP300 stability. Overexpression of HOXC-AS3 or EP300 reversed the promotion of silencing SETD1A on NSCLC cell ferroptosis. Silencing SETD1A reduced tumor volume and weight and positive rate of ki67 and increased ferroptosis through the HOXC-AS3/EP300 axis.

conclusionSETD1A-mediated H3K4me2 methylation promoted HOXC-AS3 expression, binding of HOXC-AS3 to EP300, and EP300 stability, thereby suppressing NSCLC cell ferroptosis.
