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
9 samples: 3 × untreated vs 3 × IFNA vs 3 × TNFAGroups 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)
Impaired trophoblast differentiation and invasion are a hallmark of severe pregnancy complications such as preeclampsia and fetal growth restriction. Women with immune-mediated inflammatory diseases, in particular systemic lupus erythematosus (SLE), have an increased risk for adverse pregnancy outcomes. These diseases are characterized by high activity of pro-inflammatory cytokines, such as interferon alpha (IFN-α) and tumor necrosis factor alpha (TNF-α).

Here, we investigated the direct effects of these cytokines on extravillous trophoblast (EVT) differentiation and invasion, using trophoblast stem cells (TSCs), trophoblast organoids, and first-trimester placental and decidual tissue. While neither cytokine impaired EVT differentiation, both significantly reduced EVT invasion into extracellular matrix and/or maternal decidua. Transcriptomic analysis revealed cytokine-induced alterations in gene expression associated with epithelial-mesenchymal transition (EMT), a key process in EVT invasion. These findings suggest that elevated IFN-α and TNF-α levels may directly impair placental development by inhibiting EVT invasion, providing a mechanistic link between inflammatory conditions such SLE and adverse pregnancy outcomes.

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 GSE302798_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 PRJNA1292184 and SRA study SRP601262. Searching any of these in the dataset finder brings you back here.

Study design
3 × untreated vs 3 × IFNA vs 3 × TNFA

Supports a between-group comparison across 9 samples.

How we read this: 3 replicated groups read from 9 sample titles; they account for 9 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.
