What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.

A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Paper
Glioblastoma stem cells resist cuproptosis with circadian variation of copper levelsThe Journal of clinical investigation · 2026
Summary (written by the submitters)
Copper-related cell death, cuproptosis, involves accumulation of intracellular copper that triggers mitochondrial lipoylated protein aggregation and destabilization of iron–sulfur cluster proteins. Here, glioblastoma (GBM) stem cells (GSCs) displayed resistance to cuproptosis with circadian variation of intracellular copper levels, unlike differentiated GBM cells (DGCs) or neural stem cells (NSCs).
Read the full summary ↓
CRISPR screening of copper regulators under concurrent treatment with copper ionophore or clock disruption revealed dependency on ATPase Copper Transporting Alpha (ATP7A). Circadian control of copper homeostasis was mediated by core clock transcription factor, Basic helix-loop-helix ARNT-like protein 1 (BMAL1). In turn, ATP7A promoted tumor cell growth through regulation of fatty acid desaturation. Copper levels negatively fed back onto the circadian clock through SQSTM1 (sequestosome 1/p62)-mediated lysosomal degradation of BMAL1. Targeting cuproptosis and circadian clock or fatty acid desaturation generated synergistic anti-tumor effects. Thus, crosstalk between the circadian rhythm and copper sustains GSCs, reshaping fatty acid metabolism and promoting drug resistance.

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 GSE278671_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1168173 and SRA study SRP536307. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 6 replicated groups read from 12 sample titles; they account for 12 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
