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
14 samples: 6 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.

DNA G-quadruplex profiling in skeletal muscle stem cells reveals functional and mechanistic insightsGenome biology · 2025
Summary (written by the submitters)
DNA G-quadruplexes (G4s) are non-canonical secondary structures formed in Guanine-rich DNA sequences and recent studies demonstrate G4s play important roles in modulating multiple biological processes through a variety of gene regulatory mechanisms. Emerging G4 profiling permit global mapping of endogenous G4 formation. Here in this study, we map the G4 landscapes in skeletal muscle stem cells (MuSCs) which are essential for injury induced muscle regeneration.
Read the full summary ↓
Throughout the myogenic lineage progression of MuSCs from quiescent to activated to differentiated cells, we uncover dynamic endogenous G4 formation with a pronounced G4 induction when MuSCs become activated and proliferating. We further demonstrate that G4 induction promotes MuSC activation thus the regeneration process. Mechanistically, we found that promoter associated G4s regulate gene transcription in through facilitating DNA looping. Furthermore, we found that G4 sites are enriched for transcription factor (TF) binding events in activated MuSCs and MAX binds to G4 structures to promote E-P looping and gene transcription. The above uncovered global regulatory function/mechanism are further dissected on the paradigm of CCNE1 promoter demonstrating CCNE1 is a bona fid G4/MAX regulatory target in activated MuSCs. Altogether, our findings for the first time demonstrate the prevalent and dynamic formation of G4s in MuSCs and the mechanistic role of G4s in promoting gene expression and MuSC activation/proliferation.

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 GSE289445_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: 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 PRJNA1222960 and SRA study SRP563527. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 6 replicated groups read from 14 sample titles; they account for 12 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.
