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 × M2-like BMDMs, control, 72h, vs 3 × M2-like BMDMs, YUMM5.2 eGFP cm, 72h, vs 3 × M2-like BMDMs, YUMM5.2 Ifnb1eGFP cm, 72h, vs 3 × M2-like BMDMs, recombinant IFNbeta, 72h,Groups 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.

Tumoral Interferon Beta Induces an Immune-Stimulatory Phenotype in Tumor-Associated Macrophages in Melanoma Brain MetastasesCancer research communications · 2024
Summary (written by the submitters)
Type I interferons (IFNs) are immune-stimulatory cytokines involved in antiviral and antitumor immune responses. They enhance the efficacy of immunogenic anticancer therapies by activating both innate and adaptive intratumoral immune cell populations. Macrophages are one of the most abundant innate immune cells in the immune microenvironment of melanoma brain metastases (MBMs) and can exert potent immune-suppressive functions.

Here, we investigate the potential of tumoral type I IFNs to re-polarize tumor-associated macrophages (TAMs) in a murine melanoma mouse model. We describe a pro-inflammatory and M1-like TAM phenotype induced by tumoral IFNβ and identify a myeloid type I interferon-response signature associated with a high M1/M2 TAM ratio and an increased overall survival in previously irradiated patients with MBMs. We provide evidence that tumoral IFNβ supports an effective antitumor immune response by re-educating immune-regulatory TAMs. These findings uncover type I interferon-dependent therapies as a potential macrophage-targeting therapeutic approach and provide a rationale for combining radiotherapy with concomitant immunotherapy to improve treatment response in patients with MBM.

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 GSE271267_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 PRJNA1130634 and SRA study SRP517419. Searching any of these in the dataset finder brings you back here.

Study design
3 × M2-like BMDMs, control, 72h, vs 3 × M2-like BMDMs, YUMM5.2 eGFP cm, 72h, vs 3 × M2-like BMDMs, YUMM5.2 Ifnb1eGFP cm, 72h, vs 3 × M2-like BMDMs, recombinant IFNbeta, 72h,

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.
