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
Homo sapiens (human)
Samples
27 samples: 27 samples, each with a distinct title — no replicated groupsGroups 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)
Sodium-glucose cotransporter-2 (SGLT2) inhibitors slow progression of diabetic kidney disease, but their intrarenal mechanisms remain unclear, particularly in patients with type 1 diabetes (T1D). In a prespecified ancillary study within the placebo-controlled ATTEMPT trial of dapagliflozin in youth with T1D and well-preserved kidney function (N=98), we integrated sequential kidney biopsies, multiparametric kidney MRI, and proteomics.
Read the full summary ↓
Single-cell RNA-seq of N=16 baseline and N=11 16-week follow-up biopsies (N=27; 214,415 cells) revealed a coordinated network of metabolic, fibrotic, and inflammatory transcriptional changes across nephron, vascular, and immune compartments. These gene shifts paralleled attenuation of hyperfiltration and improvement in glycemic control (HbA1c and time-in-range), implicating 594 transcripts. MRI indicated a reversal of the medullary hyperoxia characteristic of T1D with dapagliflozin. Urine proteomic profiles echoed the transcriptomic patterns. Together, these multimodal data point to metabolic reprogramming, reduced inflammation, and improved oxygen handling as convergent mechanisms of SGLT2-mediated kidney protection.

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 GSE316742_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 PRJNA1404116. Searching any of these in the dataset finder brings you back here.

Study design
27 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 27 sample titles: 27 distinct titles with little repetition. 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.
