Single-cell RNA-seq · human · 88 samples

What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.
Organism
Homo sapiens (human)
Topic
Lung cancerThis series is part of our curated briefing on it.
Samples
88 samples: 45 × scRNA-seq_P vs 43 × scTCR-seq_PGroups 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.

Summary (written by the submitters)
We launched an investigator-initiated, Simon’s two-stage design trial of neoadjuvant sintilimab combined with carboplatin and nab-paclitaxel (nab-PC) in early-stage EGFR-mutant NSCLC (Clinicaltrial.gov number NCT05244213). Here we report the first interim results of stage 1 cohort which met the overall primary endpoint in advance, and multi-omics profiling of neoadjuvant immunotherapy combination in early-stage EGFR-mutant patients.
Read the full summary ↓
We performed in-depth single-cell RNA/TCR sequencing (scRNA/TCR-seq) of cells derived from 11 resected tumors as well as 34 tumors from real-world cohort which were all confirmed wild-type lung adenocarcinoma (LUAD) or adeno-squamous carcinoma (ASC) and received neoadjuvant immunochemotherapy as control. By associating the tumor microenvironment (TME) and with responses, we uncovered heterogeneous mechanisms of primary resistance, providing insights into further strategic developments of combination regimens to improve the clinical outcome of EGFR-mutant NSCLC patients.

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 GSE241934_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1010782. Searching any of these in the dataset finder brings you back here.

Study design
45 × scRNA-seq_P vs 43 × scTCR-seq_P

Supports a between-group comparison across 88 samples.

How we read this: 2 replicated groups read from 88 sample titles; they account for 88 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.
