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)
Samples
105 samples: 29 conditions, mostly with about 4 replicates eachGroups 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)
Extracellular vesicles (EVs), released by both eukaryotic and prokaryotic cells, have emerged as key mediators of cell-to-cell communication. Recent advances highlight their crucial role in cross-kingdom communication, bridging the microbial world with human biology. Here, we investigated the molecular mechanisms underlying EV-mediated bidirectional communication within the gastrointestinal ecosystem.

Using a model that includes human colon cells and both Gram-positive and Gram-negative gut bacteria, we reveal an intricate exchange of information between these kingdoms. Our analysis uncovered highly specific responses of host cells to bacterial EVs (BEVs) and BEV-RNA cargo, including uptake rates by human cells, impact on human cell viability, and alterations in their transcriptomic landscape. In parallel, we discovered that host-derived EVs and miR-192-5p are internalized by gut bacteria, leading to changes in their growth pattern. These findings highlight the precision with which EVs and their RNA cargo mediate interkingdom communication. Our results underscore the importance of tailored, context-specific analyses for understanding the scope of EV-mediated interactions in complex biological systems.

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 GSE297395_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 PRJNA1263755 and SRA study SRP586026. Searching any of these in the dataset finder brings you back here.
