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
12 samples: 6 × NC vs 6 × SiRNAGroups 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)
This study investigates the role of USP22 in trophoblast necroptosis and preeclampsia (PE). USP22 expression was significantly downregulated in PE placental tissues, accompanied by elevated necroptosis markers RIPK1, RIPK3, and MLKL. A hypoxic HTR-8/SVneo trophoblast cell model recapitulated the PE microenvironment, where necroptosis was confirmed as the dominant death modality.

USP22 knockdown exacerbated necroptotic signaling, while USP22 overexpression restored H3K9ac and H3K27ac levels and suppressed necroptosis. RNA-seq identified 1,186 differentially expressed genes upon USP22 knockdown, including marked repression of the Wnt antagonist SFRP1. Mechanistically, USP22 directly interacted with KAT2A and stabilized it via selective removal of K48-linked polyubiquitin chains, sustaining KAT2A-dependent histone acetylation at the SFRP1 promoter to maintain SFRP1 transcription. SFRP1 restoration in USP22-deficient trophoblasts reduced cell death and decreased p-MLKL/MLKL ratio. The L-NAME rat PE model confirmed coordinated downregulation of USP22, KAT2A, SFRP1, and histone acetylation in vivo.

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 GSE327405_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 PRJNA1450656 and SRA study SRP690230. Searching any of these in the dataset finder brings you back here.

Study design
6 × NC vs 6 × SiRNA

Supports a between-group comparison across 12 samples.

How we read this: 2 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.
