What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Homo sapiens (human)
Samples
28 samples: 28 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)
Aberrant chromatin-associated condensates have emerged as drivers of gene dysregulation in cancer, yet the mechanisms regulating their formation and function remain poorly understood. Mutations in the histone acetylation reader ENL, recurrent in leukemia and Wilms tumor, drive oncogenesis by inducing condensate formation at selective target loci.
Read the full summary ↓
Here, we show that RNA promotes the nucleation, chromatin engagement, and oncogenic activity of ENL mutant condensates. Mutant ENL binds RNA via a conserved basic patch within the YEATS domain, and this interaction enhances condensate formation in vitro and in cells. Acute displacement and reassembly experiments demonstrate that interactions with local RNA transcripts facilitate condensate nucleation efficiency at endogenous target loci. Partial disruption of RNA binding preferentially impairs chromatin occupancy of ENL mutants at condensate-permissive loci, leading to reduced transcriptional bursting and target gene expression. In mouse models, disrupting RNA binding compromises mutant ENL-driven gene expression and malignant self-renewal, halting disease progression and prolonging survival. These findings uncover a previously unrecognized role of RNA in promoting the formation and oncogenic function of chromatin-associated condensate.

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 GSE300418_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1280910 and SRA study SRP594051. Searching any of these in the dataset finder brings you back here.

Study design
28 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 28 sample titles: 28 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.
