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
Mus musculus (mouse)
Samples
12 samples: 3 × B16_mche_pos vs 3 × B16_mche_neg vs 3 × MC38_mche+ vs 3 × MC38_mcheGroups 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
Platelet factor 4-induced T(H)1-T(reg) polarization suppresses antitumor immunityScience (New York, N.Y.) · 2024
Summary (written by the submitters)
The tumor microenvironment (TME) contains various immune-suppressive cells such as T helper 1-polarized regulatory T cells (Th1-Tregs). However, little is known about the mechanism behind the abundant presence of Th1-Tregs in TME. In this work, we demonstrate that selective depletion of arginase I (Arg1)-expressing tumor associated macrophages (Arg1+ TAMs) inhibits tumor growth and concurrently reduces the Th1-Treg ratio in TME.
Read the full summary ↓
Notably, Arg1+ TAMs secrete platelet factor 4 (PF4) that reinforces interferon-γ (IFN-γ)-induced Treg polarization into Th1-Tregs in a manner dependent on CXCR3 and the IFN-γ receptor. Both genetic PF4 inactivation and PF4 neutralization hinder Th1-Treg accumulation in TME, consequently suppressing tumor growth. Collectively, our study highlights the importance of Arg1+ TAM-produced PF4 for high Th1-Treg levels in TME to suppress anti-tumor immunity, and demonstrates PF4 neutralization as a potential cancer immunotherapeutic strategy.

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 GSE252052_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 PRJNA1057209 and SRA study SRP480134. Searching any of these in the dataset finder brings you back here.

Study design
3 × B16_mche_pos vs 3 × B16_mche_neg vs 3 × MC38_mche+ vs 3 × MC38_mche

Supports a between-group comparison across 12 samples.

How we read this: 4 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.
