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
134 samples: 8 conditions, mostly with about 40 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.

Suppression of ERK signalling promotes pluripotent epiblast in the human blastocystNature communications · 2025
Summary (written by the submitters)
Studies in the mouse demonstrate the importance of fibroblast growth factor (FGF) and extra-cellular receptor tyrosine kinase (ERK) in specification of the epiblast and hypoblast in the inner cell mass (ICM). We recently demonstrated cross-talk of ERK and PI3K activity downstream of FGF and insulin growth factor signaling. We therefore hypothesized that ERK may have a conserved role in human hypoblast versus epiblast specification.

Here we determined that FGF signaling is sufficient to specify hypoblast in human blastocysts. We describe ERK signaling during the blastocyst stage and demonstrate that blocking ERK activity, by small-molecule inhibition, is necessary for hypoblast specification in human blastocysts, and leads to expansion of the epiblast cells functionally capable of giving rise to naïve pluripotent embryonic stem cells. Transcriptomic analysis further reveals that these epiblast cells downregulate insulin growth factor and FGF signaling, while maintaining molecular markers of the epiblast. Moreover, we generate human naïve pluripotent stem cells following ERK inhibition. Our functional studies provide mechanistic insight into human blastocyst formation. We propose a unified model in which segregation of the epiblast and hypoblast lineages occurs during maturation of the mammalian blastocyst in an FGF/ERK signal-dependent manner.

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 GSE239843_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 PRJNA1001047 and SRA study SRP452661. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 133 samples.

How we read this: 8 replicated groups read from 134 sample titles; they account for 133 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.
