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.

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)
The mRNA-binding protein KSRP (KH-type splicing regulatory protein) is known to modulate immune cell functions post-transcriptionally e.g. by reducing the mRNA stability of cytokines. It is known that KSRP binds AU-rich motifs (ARE) within the 3´-untranslated region of mRNA spe-cies, which in many cases encode dynamically regulated proteins like cytokines.

Innate myeloid immune cells, such as polymorphonuclear neutrophils (PMN) or macrophages (MAC) eliminate pathogens by multiple mechanisms, including phagocytosis, as well as secretion of chemo- and cytokines. Here, we investigated the role of KSRP on the phenotype and functions of both innate immune cell types in mouse model of invasive pulmonary aspergillosis (IPA). Here, KSRP-/- mice showed lower levels of Aspergillus fumigatus conidia (AFC) and an increase in the frequencies of PMN and MAC in the lungs. Our results showed that PMN and MAC from KSRP-/- mice exhibited enhanced phagocytic uptake of AFC, accompanied by increased ROS production in PMN upon stimulation. As a comparison of RNA sequencing data revealed that 64 genes related to inflam-matory and immune responses were shared between PMN and MAC. The majority of genes up-regulated in PMN were involved in metabolic processes, cell cycle and DNA repair. In agreement, KSRP-deficient PMN displayed reduced levels of apoptosis. In conclusion, our results indicate that KSRP serves as a critical negative regulator of PMN and MAC anti-pathogen activity.

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 GSE280203_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 PRJNA1177345 and SRA study SRP540587. Searching any of these in the dataset finder brings you back here.

Study design
3 × PMN, WT, biol vs 3 × PMN, KO, biol

Supports a between-group comparison across 6 samples.

How we read this: 2 replicated groups read from 12 sample titles; they account for 6 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.
