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
16 samples: 8 conditions, mostly in duplicateGroups 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)
DNA topology is critical for regulating transcription and maintaining cellular homeostasis. Z-DNA is a left-handed DNA helix in regions with high transcriptional activity. Its physiological function remains poorly understood. Here, we demonstrate that oncoprotein MYC induces the formation of Z-DNA by recruiting the chromatin remodeler FACT, independent of RNA Polymerase II activity.
Read the full summary ↓
FACT facilitates Z-DNA formation by remodeling H2A/H2B dimers within intact nucleosomes. Additionally, the phosphorylation of FACT regulates its liquid-liquid phase separation, promoting its efficient recruitment to chromatin by MYC. Through a genome-wide analysis and characterization of engineered Z-DNA promoters, we found that Z-DNA directly facilitates the loading of RNA Polymerase II, thereby promoting transcriptional activity. This study elucidates the molecular mechanisms of Z-DNA dynamics and emphasizes its functional importance in transcriptional regulation, providing insights into the role of non-B-DNA structures in chromatin biology and MYC-driven cancer.

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 GSE290659_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 PRJNA1229495 and SRA study SRP566911. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 16 samples.

How we read this: 8 replicated groups read from 16 sample titles; they account for 16 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.
