What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.
Organism
Mus musculus (mouse)
Samples
28 samples: 9 conditions, mostly with about 4 replicates eachGroups 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
Set7 Methyltransferase and Phenotypic Switch in Diabetic Glomerular Endothelial CellsJournal of the American Society of Nephrology : JASN · 2024
Summary (written by the submitters)
Set7 knockout (Set7KO) improved glomerular structure and albuminuria in a mouse model of diabetes. Analysis of mouse single-cell RNA-sequencing data showed dynamic transcriptional changes in diabetic renal cells. Set7KO controls phenotype switching of GEN cell populations through transcriptional regulation of the insulin growth factor binding protein 5 (IGFBP5).
Read the full summary ↓
Chromatin immunoprecipitation assays confirmed that the expression of the IGFBP5 gene was associated with mono- and dimethylation of histone H3 lysine 4 (H3K4me1/2). This generalizability was investigated in human renal and circulating hyperglycemic cells exposed to TGFb1. We showed that the highly selective Set7 inhibitor PFI-2 attenuated indices associated with renal cell damage and mesenchymal transition, specifically (1) reactive oxygen species production, (2) IGFBP5 gene regulation, and (3) expression of mesenchymal markers. Furthermore, renal benefit observed in Set7KO diabetic mice closely corresponds in human glomerular endothelial cells with PFI-2 inhibition or Set7 shRNA silencing.

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 GSE158626_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA666001 and SRA study SRP285544. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 28 samples.

How we read this: 9 replicated groups read from 28 sample titles; they account for 28 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.
