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.

18 samples: 6 conditions, mostly in triplicateGroups 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.

Constitutive epidermal expression of osteopontin in osteopontin-null mice restores ultraviolet B-induced cutaneous squamous cell carcinomas to wild-type levelsCarcinogenesis · 2025
Summary (written by the submitters)
Studies of osteopontin (OPN)-null mice have supported the role of OPN as a critical factor in the promotion of skin tumorigenesis. OPN is a highly inducible integrin- and CD44-interacting acidic glycoprotein with pleiotropic functions. In various types of cancer, elevated levels of OPN derived from cancer and from inflammatory cells are secreted into the microenvironment and the bloodstream.

To determine whether OPN expressed by keratinocytes without any contribution from activated resident and infiltrating inflammatory cells promotes cutaneous tumor development, transgenic mice with constitutive epidermal expression of OPN in an OPN-null background, tg(K14-OPN) were generated. In photocarcinogenesis studies, tumor multiplicity and the incidence of cutaneous squamous cell carcinoma (cSCC) was similar between tg(K14-OPN) and wild-type (WT) mice. Consistent with our previous findings, constitutive epidermal expression of OPN enhanced the survival of acute ultraviolet B (UVB)-induced cell death compared with OPN-null mice and did not enhance UVB-induced epidermal hyperplasia compared to OPN-null or WT mice. Additionally, tg(K14-OPN) and OPN-null mice irradiated with long-term low dose UVB had significantly lower numbers of mutated p53 keratinocytes than WT mice. RNA-sequencing data from the epidermis of acute UVB-irradiated tg(K14-OPN) versus OPN-null mice compared to UVB-irradiated WT versus OPN-null mice suggests the importance of inflammation, Wnt, integrin and gonadotropin-releasing hormone receptor signaling in cutaneous tumorigenesis and implicates UVB irradiation and its induction of OPN in driving those pathways. In summary, the constitutive epidermal expression of OPN in OPN-null mice facilitates the development of cSCC comparable to WT mice.

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 GSE271536_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 PRJNA1132181 and SRA study SRP518125. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 18 samples.

How we read this: 6 replicated groups read from 18 sample titles; they account for 18 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.
