Single-cell RNA-seq · human · 22 samples

What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart.
Organism
Homo sapiens (human)
Samples
22 samples: 10 × bulkRNA-seq, HF vs 8 × bulkRNA-seq, HMGroups 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)
The epigenetic landscape and tumor microenvironment (TME) interactions of non-functioning pituitary adenomas (NFPAs), benign tumors with high morbidity and recurrence rates, are not well characterized. We completed single-nucleus (sn) multiomics assays on four gonadotrope NFPAs. We identified genes involved in bidirectional tumor-macrophage crosstalk.
Read the full summary ↓
We uncovered coordinated gene expression and chromatin accessibility programs that distinguished adenoma cells from gonadotropes. Integrated transcriptome-chromatin modeling revealed gene regulatory circuits that showed altered activity in adenoma cells. Our study provides insight into the altered epigenetic gene-control landscape and TME processes of the NFPA tumor phenotype.

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 GSE295449_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 PRJNA1254698 and SRA study SRP580858. Searching any of these in the dataset finder brings you back here.

Study design
10 × bulkRNA-seq, HF vs 8 × bulkRNA-seq, HM

Supports a between-group comparison across 18 samples.

How we read this: 2 replicated groups read from 22 sample titles; they account for 18 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.
