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

Breast cancerThis series is part of our curated briefing on it.
Samples
14 samples: 7 × Neutrophils mTNBC vs 7 × Neutrophils HDGroups 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.

Triple-negative breast cancer modifies the systemic immune landscape and alters neutrophil functionalityNPJ breast cancer · 2025
Summary (written by the submitters)
Cancer dysregulates intratumoral innate-adaptive immune cell crosstalk, but it remains largely unknown how the systemic immune landscape is modified during breast cancer progression. Here, we comprehensively profiled the circulating immune profile of patients with stage I-III or stage IV triple-negative breast cancer (TNBC) and healthy donors (HDs).
Read the full summary ↓
We showed that patients with metastatic TNBC (mTNBC) exhibited decreased numbers of circulating T cells, dendritic cell subsets and differentiated B cells compared to patients with stage I-III TNBC and HDs, which was partially associated with prior chemotherapy. Moreover, increased IL17 production by vδ1 γδ T cells was observed in patients with mTNBC compared to HDs. Classical monocytes and neutrophils were increased in patients with mTNBC compared to HDs, irrespective of prior chemotherapy. Transcriptional and proteomic analysis, alongside ex vivo functionality assays, revealed increased migratory capacity, increased abundance of granule proteins, and elevated ROS production in circulating neutrophils from mTNBC patients. Some of these systemic immune alterations, including decreased levels of non-switched B cells and increased migratory capacity of neutrophils, were already evident in patients with stage I-III TNBC. Our data underscore the significant impact of TNBC disease stage on the systemic immune composition and function.

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 GSE264108_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 PRJNA1101001 and SRA study SRP502162. Searching any of these in the dataset finder brings you back here.

Study design
7 × Neutrophils mTNBC vs 7 × Neutrophils HD

Supports a between-group comparison across 14 samples.

How we read this: 2 replicated groups read from 14 sample titles; they account for 14 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.
