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.

Sleeve gastrectomy reveals the plasticity of the human gastric epitheliumNature communications · 2025
Summary (written by the submitters)
Gastric acidity is essential for the function of the human stomach. pH homeostasis is facilitated by gastrin, a hormone secreted from the gastric antrum in response to a rise in pH, leading to acid secretion from the gastric corpus. Sleeve gastrectomy (SG), a bariatric surgery in which 80% of the gastric corpus is excised, presents a challenge for gastric pH homeostasis.

We used histology and single-cell RNA sequencing to study the gastric antrum and corpus epithelium of naïve patients, and of patients who underwent SG years earlier. SG was associated with an increase in a sub-population of acid-secreting parietal cells which overexpress respiratory enzymes and carbonic anhydrase, and an increase in the fraction of histamine-secreting enterochromaffin-like cells (ECLs). Notably, ECLs of SG-operated patients over-expressed genes coding for biosynthesis of neuropeptides and of serotonin. Mathematical modeling of pH homeostasis by gastrin showed that fasting pH is not sensitive to nearly all model parameters. Robustness is a result of the ability of gastrin to induce acid secretion as well as increase the number of ECLs and parietal cells, a feedback analogous to a non-linear proportional and integral feedback control, that drives adaptation of the epithelium to acid-secretion demand. Quantitative predictions of the model on the gastric response to SG were validated in patients: SG induced a 5-fold increase in blood gastrin levels as early as one day post-surgery, and an over 30% increase in the number of parietal cells and ECLs per gland years after surgery. Together, these empirical and modeling data demonstrate how the human gastric epithelium remodels following SG at the molecular and cellular levels, and more generally how trophic hormones such as gastrin enable robust adaptation of tissue function to meet physiological demand.

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 GSE263018_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 PRJNA1095460 and SRA study SRP499374. Searching any of these in the dataset finder brings you back here.

Study design
31 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 31 sample titles: 31 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.
