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: 3 × PHSC_Solvent vs 3 × PHSC_TGFβ vs 3 × LX2_Solvent vs 3 × LX2_TGFβGroups 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.
Paper
An Integrative Transcriptome Subtraction Strategy to Identify Human lncRNAs That Specifically Play a Role in Activation of Human Hepatic Stellate CellsNon-coding RNA · 2024
Summary (written by the submitters)
Liver fibrosis stands as the most prominent predictor of overall mortality in non-alcoholic steatohepatitis (NASH). The fibrotic liver features excessive deposition of extracellular matrix (ECM), primarily produced from "activated" hepatic stellate cells (HSCs). Whereas targeting HSC in fibrosis therapeutics shows promise, the current identification of human genetic regulators driving HSC activation is far from complete.
Read the full summary ↓
This knowledge gap largely emanates from the limited understanding of the vast array of long non-coding RNAs (lncRNAs). Analyzing differentially regulated human lncRNAs under various regulatory patterns often provides the most practical means to inform their function. To get human lncRNA regulators in driving HSC activation, we cultured both primary human stellate cells and LX-2 cells. Then, we treated them with TGFb to mimic the activation process in vitro. Differentially expressed lncRNAs can be obtained from RNAseq results, which may guide the characterization of lncRNAs relevant to HSC activation.

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 GSE253493_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 PRJNA1065892 and SRA study SRP484285. Searching any of these in the dataset finder brings you back here.

Study design
3 × PHSC_Solvent vs 3 × PHSC_TGFβ vs 3 × LX2_Solvent vs 3 × LX2_TGFβ

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.
