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

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
HSD17B13 liquid-liquid phase separation promotes leukocyte adhesion in chronic liver inflammationJournal of molecular cell biology · 2024
Summary (written by the submitters)
Loss-of-function variants in 17-beta hydroxysteroid dehydrogenase 13 (HSD17B13) are associated with decreased inflammation in human chronic liver disease. The underlying mechanism by which HSD17B13 promotes liver inflammation remains largely elusive. Here we find that HSD17B13 undergoes liquid-liquid phase separation (LLPS) around lipid droplets (LDs) in the liver of NASH patients.
Read the full summary ↓
Dimerization of HSD17B13 drives LLPS formation and regulates its enzyme activity. HSD17B13 LLPS promotes leukocyte adhesion and fibrinogen expression in hepatocytes via activating autocrine platelet activating factor (PAF) signaling. Importantly, adeno-associated viral (AAV)-mediated xeno-expression of human HSD17B13 promotes liver inflammation in Hsd17b13-/- mice induced by high fat diet/carbon tetrachloride treatment. In conclusion, HSD17B13 LLPS triggers liver inflammation via promoting PAF-mediated leukocyte adhesion. Targeting HSD17B13 phase transition would be a promising approach to treat liver inflammation in chronic liver disease.

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 GSE238060_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 PRJNA997902 and SRA study SRP451004. Searching any of these in the dataset finder brings you back here.

Study design
3 × HepaRG cells, HSD17B13, vs 3 × HepaRG cells, Control, vs 3 × KO mus hepatocytes, AAV human HSD17B13, vs 3 × KO mus hepatocytes, AAV control,

Supports a between-group comparison across 12 samples.

How we read this: 4 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.
