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
11 samples: 4 × WT_HFD_LNAME vs 4 × WT_CD vs 3 × MPST KO_HFD_LNAMEGroups 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.

Protective role of 3-mercaptopyruvate sulfurtransferase (MPST) in the development of metabolic syndrome and vascular inflammationPharmacological research · 2025
Summary (written by the submitters)
Metabolic syndrome (MetS), a cluster of metabolic abnormalities that occur concurrently that significantly increases the risk of cardiovascular disease and mortality. 3-mercaptopyruvate sulfurtransferase (MPST), a cysteine-catabolizing enzyme that yields pyruvate and hydrogen sulfide (H2S), plays a central role in the regulation of energy homeostasis.

Herein, we seek to investigate the role of MPST/H2S in MetS using a mouse model of the disease.Wilt type (WT) mice were fed a high-fat diet (HFD) for 15 weeks to induce obesity and hyperglycemia, and followed by a nitric oxide synthase inhibitor, for the additional 5 weeks to induce hypertension and MetS. This MetS mouse model caused a mild diastolic and endothelial dysfunction. We observed that, MetS was characterized by decreased levels of free H2S and sulfane-sulfur and downregulation of MPST in the aorta of animals with MetS. Global deletion of Mpst (Mpst-/-) results in increased body weight and greater glucose intolerance in mice with MetS, without affecting their blood pressure. Whole transcriptome analysis in aortic tissue revealed an upregulation of genes involved in the immune response; CD8+ cell infiltration and T-cell activation-related pathways were observed among the most affected biological processes in Mpst-/- mice with MetS.

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 GSE273901_RAW.tar (it can run to tens of gigabytes).

All supplementary files ↗ Whole study · RAW.tar ↓
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.

Raw reads on ENA ↗

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 PRJNA1143572 and SRA study SRP523979. Searching any of these in the dataset finder brings you back here.

4 × WT_HFD_LNAME vs 4 × WT_CD vs 3 × MPST KO_HFD_LNAME

Supports a between-group comparison across 11 samples.

How we read this: 3 replicated groups read from 11 sample titles; they account for 11 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.
