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
Mus musculus (mouse)
Samples
14 samples: 4 × p63alpha_Epidermis vs 4 × p63beta_Epidermis vs 3 × p63alpha_Ker_RNA vs 3 × p63beta_Ker_RNAGroups 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)
The transcription factor p63 is a master gene of epithelial development. p63 regulates expression of genes related to proliferation, differentiation and adhesion by binding epithelial enhancers. Biochemically, p63 interacts with chromatin via its DNA binding domain, while N-terminus is essential for the fine tuning of its transcriptional activity.

However, the role of the C-terminus of p63 remains elusive. Here, we investigate the role of the C-terminal SAM domain of p63 in vivo. We generated Krt14-specific knock-out of the SAM domain (exon 13) of p63 which resulted in expression of the p63b isoform. Most of p63b expressing mice die 2-3 months after birth and show alteration of skin, adipose tissue and muscle morphology. Mechanistically, ChIP-seq analysis showed an increased binding of p63b to gene promoters. Further integration of transcriptome and genome occupancy analyses revealed that p63b binds more readily promoter regions of extracellular matrix (ECM) genes leading to their enhanced expression. Aberrant expression of ECM genes by p63b disrupts normal adhesion of keratinocytes to basal lamina triggering systemic inflammation and premature death. Altogether, our data suggest that C-terminus ensures p63 selectivity in enhancer binding to maintain physiological levels of extracellular matrix and adhesion proteins.

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 GSE241109_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 PRJNA1004840. Searching any of these in the dataset finder brings you back here.

Study design
4 × p63alpha_Epidermis vs 4 × p63beta_Epidermis vs 3 × p63alpha_Ker_RNA vs 3 × p63beta_Ker_RNA

Supports a between-group comparison across 14 samples.

How we read this: 4 replicated groups read from 14 sample titles; they account for 14 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.
