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.

16 samples: 4 × CV vs 4 × CM_2.5 vs 4 × EV vs 4 × EM_2.5Groups 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)
Estrogens impair bile acid (BA) homeostasis, leading to intrahepatic cholestasis of pregnancy (ICP). ICP is characterized by elevated serum bilirubin and BAs, severe pruritus, and an increased risk of adverse perinatal outcomes. The constitutive androstane receptor (CAR) regulates genes involved in xenobiotic and BA detoxification. Previous studies suggest that CAR activation is protective in bile duct ligation–induced cholestasis and that major genes involved in BA elimination are downregulated in ethinylestradiol (EE)–induced cholestasis in mice.

We examined whether CAR ligands could ameliorate cholestasis and prevent hepatic injury in an EE-induced cholestasis model using biochemical, transcriptomic, and BA metabolomic analyses. We found that estradiol inhibits and downregulates CAR target genes in vitro. Consistently, EE significantly suppresses hepatic CAR target gene expression in vivo, whereas the murine CAR agonist TCPOBOP partially restores the expression of selected detoxification genes, improves plasma alkaline phosphatase levels, and decreases hepatic BA accumulation. In humanized PXR–CAR–CYP3A mice with EE-induced cholestasis, MI763F, a novel and potent human CAR agonist, recapitulates the effects of TCPOBOP on key genes involved in BA metabolism and the BA metabolome, and significantly reduces hepatic BA accumulation. These results demonstrate that CAR ligands counteract EE-mediated disruption of genes involved in BA homeostasis.

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 GSE314547_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 PRJNA1391489 and SRA study SRP656799. Searching any of these in the dataset finder brings you back here.

Study design
4 × CV vs 4 × CM_2.5 vs 4 × EV vs 4 × EM_2.5

Supports a between-group comparison across 16 samples.

How we read this: 4 replicated groups read from 16 sample titles; they account for 16 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.
