What it is
ChIP-seq / ATAC-seq (genome binding and open chromatin)Where proteins bind the genome, or which regions are open and active.
Organism
Homo sapiens (human)
Samples
66 samples: 58 distinct titles, 8 of them repeatedGroups 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)
Polycomb repressive complex 2 (PRC2) represses transcription by trimethylation of histone H3 at lysine 27. Valemetostat is a potent inhibitor of enhancer of zeste homolog (EZH)2 and EZH1, which are histone methyltransferases of PRC2. PRC2 inhibitors, including valemetostat, have been showing promises in multiple cancer types. PRC2 inhibitors, however, can induce thrombocytopenia as a class adverse effect.
Read the full summary ↓
To better understand valemetostat-induced thrombocytopenia, we performed single-cell ATAC-seq and bulk RNA-seq for human bone marrow CD34+ cells that were in vitro differentiated into megakaryocytes.

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 GSE270684_RAW.tar (it can run to tens of gigabytes).

All supplementary files ↗ Whole study · RAW.tar ↓
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.

Raw reads on ENA ↗

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1127050 and SRA study SRP515426. Searching any of these in the dataset finder brings you back here.
