Paper
Enhanced Activities of OCT4 and SOX2 Promote Epigenetic Reprogramming by Shortening G1 PhaseAdvanced science (Weinheim, Baden-Wurttemberg, Germany) · 2025
Summary (written by the submitters)
Fusing VP16 transcription activation domain with OCT4 and SOX2 (OvSvK) promoted the generation of induced pluripotency stem cells (iPSCs) by remodeling cell cycle and epigenetic modification. Multiomic analyses revealed that the other 80% upregulated genes experienced increase in H3K4me3 and decrease in H3K27me3 and were enriched with genes which undergo more intensive DNA demethylation during cell proliferation.

Consistent results were obtained when siCcnd1, siCdkn2a and Ccne1 were screened out and used to mimic the cell cycle remodeling. In summary, these studies set up a correlation between epigenetic modification during cell cycle remodeling and cell fate conversion.

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 GSE294288_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1248943 and SRA study SRP578038. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 10 samples.

How we read this: 5 replicated groups read from 11 sample titles; they account for 10 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.
