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)
Topic
Acute myeloid leukemiaThis series is part of our curated briefing on it.
Samples
158 samples
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
Nucleotide depletion promotes cell fate transitions by inducing DNA replication stressDevelopmental cell · 2024
Summary (written by the submitters)
Certain cancers, such as acute myeloid leukemia (AML), are caused by malignant stem cells that fail maturation. We sought to mechanistically understand how metabolism might regulate cell fate decisions and to identify metabolic differentiation agents that might be leveraged therapeutically.  We find that nucleotide – purine, pyrimidine, and deoxynucleotide – depletion leads to AML differentiation by way of replication stress.
Read the full summary ↓
Modulation of nucleotide pools leads to transcriptional reprogramming, epigenetic remodeling, and initiation of differentiation which is dependent on the myeloid regulating transcription-factor PU.1. By single-cell RNA sequencing and microscopy, we find that reprogramming downstream of nucleotide depletion occurs as cells undergo replication stress and that the cell fate decision is initiated prior to completion of the cell cycle. Together, these findings suggest that nucleotide metabolism is a critical determinant of hematopoietic progenitor cell fate, clarify the coordination of the fate decision with the cell cycle, and expand upon the class of inhibitors that can be developed or repurposed as novel differentiation therapy.

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 GSE172333_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 PRJNA722986 and SRA study SRP315357. Searching any of these in the dataset finder brings you back here.
