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.
Paper
G3BP isoforms differentially affect stress granule assembly and gene expression during cellular stressMolecular biology of the cell · 2024
Summary (written by the submitters)
Stress granules (SGs) are macromolecular assemblies that form under cellular stress. Their function is not completely understood. Formation of these organelles is driven by the nucleation of proteins such as G3BPs. G3BPs are RNA-binding proteins that condense into SGs following translation shutoff during the integrated stress response (ISR).

Three G3BP paralogs (G3BP1, G3BP2A, and G3BP2B) have been identified in vertebrates. Here, we found a molecular tool to study G3BP condensation into SGs by mutating residue V11 of G3BPs. This conserved amino acid potentiates the G3BP-Caprin-1 complex, hence promoting SG assembly. Ribosome profiling revealed that disruption of G3BP condensation impacts mRNA expression during the ISR. Moreover, we found that G3BP2B robustly condenses and promotes changes in mRNA expression under endoplasmic reticulum (ER) stress. This indicates that G3BP paralogs differentially regulate SG assembly and gene expression programs. Together, this work suggests that stress granule assembly promotes changes in gene expression to mediate stress-response during the ISR.

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 GSE254629_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 PRJNA1071162 and SRA study SRP486945. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 20 samples.

How we read this: 10 replicated groups read from 20 sample titles; they account for 20 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.
