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
Mus musculus (mouse)
Samples
23 samples: 8 × DMSO, A vs 8 × CamSA, B vs 7 × CA-Quin, CGroups 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)
We previously reported that two bile acid (BA) analogs CamSA and CA-Quin demon-strate potent anti-germination activity against Clostridioides difficile (C. difficile) spores, protecting rodents from C. difficile infections. Here we further evaluated the impact of these analogs on the hepatic transcriptome and BA homeostasis in vivo by focusing BA profiles on the liver, feces, and chyme as well as hepatic transcriptome after a 7-day treatment.

The two compounds demonstrated similar impact on BA profiles among the three samples, with significantly increased BA excretion in feces. This change is aligned with significantly altered expression of genes involved in BA homeostasis in both liver and gut tissues. Also, both compounds increased levels of unconjugated BAs in the feces, indicating an elevated activity of gut microbiota (GM). Notably, fecal levels of anti-c. difficile germination chenodeoxycholate and pro-germination taurocholate are signifi-cantly increased and decreased by the treatments, respectively. While hepatic tran-scriptome did not show significant toxicity, altered genes are enriched in pathways as-sociated with GM activity and lipid metabolism. Overall, our study suggests that in vivo CamSA and CA-Quin treatment demonstrated minimal hepatoxicity but significantly altered BA homeostasis and potentially favorable improvement for GM profiles that together inhibit C. difficle germination.

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 GSE309065_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 PRJNA1333885 and SRA study SRP626329. Searching any of these in the dataset finder brings you back here.

Study design
8 × DMSO, A vs 8 × CamSA, B vs 7 × CA-Quin, C

Supports a between-group comparison across 23 samples.

How we read this: 3 replicated groups read from 23 sample titles; they account for 23 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.
