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

Solid malignancies contain subsets of multipotent cells that grow as spheres and efficiently propagate tumors in xenograft models, reflecting a stem-like, self-renewing and tumor-propagating phenotype. These cancer 'stem cells (SCs)' have been shown to maintain tumor growth, contribute to resistance and drive tumor recurrence. Cancer cell stemness is dynamically influenced by epigenetic mechanisms and differentially regulated coding and noncoding RNAs. How these mechanisms specifically contribute to the generation and/or maintenance of cancer SCs remains unclear. This study identifies a novel epigenetically regulated circuit that integrates microRNA, chromatin remodeling and the reprogramming transcription factor Sox2 to regulate glioblastoma (GBM)-propagating SCs. We show that miR-296-5p expression is repressed in a DNA methylation-dependent manner under conditions that promote GBM cell stemness and that miR-296-5p inhibits GBM cell stemness and their capacity to self-renew as spheres and propagate glioma xenografts in vivo. We show that the chromatin remodeling protein HMGA1 functions as a downstream effector of these biological responses to miR-296-5p and regulates Sox2 expression, a master driver of cell stemness, by modifying chromatin architecture at the Sox2 promoter. These results show for the first time that miR-296-5p inhibits transcriptional mechanisms that support GBM SCs and identify a miR-296-5p:HMGA1:Sox2 axis as a novel regulator of GBM SCs and candidate pathway for targeting therapies directed at depleting tumors of their tumor-propagating stem cell subsets.
