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.
Organism
Homo sapiens (human)
Topic
GlioblastomaThis series is part of our curated briefing on it.
Samples
16 samples: 6 conditions, mostly in duplicateGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
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.

On-demand GLUT3 expression augments CAR T cell metabolic fitness and antitumor efficacy in preclinical models of glioblastomaScience translational medicine · 2026
Summary (written by the submitters)
We show that the dysfunction of CAR-T cells in GBM is attributed to glucose deficiency in the tumor microenvironment (TME) and that on-demand, but not continuous, metabolic replenishment significantly improves the antitumor efficacy of CAR-T cells. The massive consumption of glucose by cancer cells reduces the glucose level in the TME of GBM, consequently impairing CAR-T cells.
Read the full summary ↓
Adding stable expression of glucose transporter 3 (GLUT3), a high-affinity glucose transporter, to CAR-T cells restored their cytokine production and killing activity. However, whereas CAR-T cells with stable GLUT3 expression induced tumor reduction in a GBM model, their overactivation led to adverse events and mouse death. On-demand GLUT3-expressing CAR-T cells, in which GLUT3 transcription is driven by the nuclear translocation of nuclear factor of activated T cells (NFAT) by target antigen stimulation, exhibited enhanced metabolic fitness and increased antitumor efficacy, leading to long-lasting tumor control in intracranial human GBM cell xenograft models whereas it prevented adverse events.

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 GSE320375_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 PRJNA1427689 and SRA study SRP679082. 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 16 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.
