G-quadruplex stabilizer CX-5461 effectively combines with radiotherapy to target α-thalassemia/mental retardation X-linked-deficient malignant gliomaNeuro-oncology · 2025
Summary (written by the submitters)
Mutational inactivation of ?-thalassaemia/mental retardation X-linked (ATRX) represents a defining molecular feature in large subsets of adult and pediatric malignant glioma. ATRX deficiency gives rise to abnormal G-quadruplex (G4) DNA secondary structures at GC-rich regions of the genome, altering chromatin accessibility and enhancing DNA damage.

Building on earlier work, we sought to assess the extent to which pharmacological G4 stabilization selectively enhances DNA damage and cell death in preclinical models of ATRX-deficient glioma. In this study, we assessed the extent to which G4 stabilization impacted genome-wide deposition of H3.3 in patient-derived glioma stem cells (GSCs). In order to evaluate the overlap of these H3.3 deposition sites with regions of the genome that bind ATRX, we performed cleavage under targets and tagmentation (CUT&Tag) for ATRX using GSC line TS 543. Our analyses show that G4 stabilizer CX-541 disrupts H3.3 deposition at regions of the genome that frequently bind ATRX.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE276481_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1157443 and SRA study SRP530780. Searching any of these in the dataset finder brings you back here.
