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
Breast cancerThis series is part of our curated briefing on it.
Samples
401 samples: 401 samples, each with a distinct title — no replicated groupsGroups 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.
Paper
Longitudinal transcriptomic profiling identifies predictors of response to neoadjuvant chemoimmunotherapy in triple-negative breast cancer: results from the NeoTRIPaPDL1 trialAnnals of oncology : official journal of the European Society for Medical Oncology · 2026
Summary (written by the submitters)
Triple-negative breast cancer (TNBC) is immunogenic, but only a subset of patients benefits from neoadjuvant immune checkpoint inhibitors (ICIs) combined with chemotherapy. Predictive biomarkers to guide patient selection and treatment adaptation are lacking. In the NeoTRIPaPDL1 (NeoTRIP) Phase III trial, 280 high-risk TNBC patients were randomized to neoadjuvant carboplatin plus nab-paclitaxel (CT, n=142) or the same regimen with atezolizumab (CT/A, n=138).
Read the full summary ↓
Tumor biopsies were collected at baseline and on the first day of the second cycle (D1C2). Longitudinal transcriptome sequencing and analyses of selected gene signatures were performed, including hallmark, ferroptosis-related, and immune cell type–specific signatures. Treatment-induced gene expression changes and association with pathological complete response were investigated.

This dataset
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 GSE319641_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 PRJNA1424908. Searching any of these in the dataset finder brings you back here.

Study design
401 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from the first 400 of 401 sample titles: 400 distinct titles with little repetition. 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.
