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.

19 samples: 5 × NPp53 homonally intact biol vs 5 × NPp53T homonally intact biol vs 5 × NPp53 castrated biol vs 3 × NPp53T castrated biolGroups 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)
Tripartite motif-containing 28 (TRIM28/TIF1b/KAP1) is a key transcriptional co-repressor protein that represses ERV expression in many cell types including embryonic stem cells, neural progenitor cells, differentiated adult cells, and cancer cells. In this study, we investigated the effect of Trim28 deletion on the expression of ERVs using an immune competent genetically engineered mouse model for prostate cancer.
Read the full summary ↓
We found Trim28 deletion in prostate tumors led to the expression of ERVs in prostates from both hormonally intact and castrated mice. ERVs can regulate the expression of neighboring genes, and we detected increased expression of several protein-coding genes near overexpressed ERVs. Our data suggest that Trim28 deletion in prostate tumor epithelial cells may promote an innate immune response. However, Trim28 deletion also led to excessive deposition of tumor extracellular matrix (ECM). Our findings suggest that ECM alterations downstream of ERV derepression could affect immune cells in the tumor microenvironment and may promote tumor progression.

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 GSE298402_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 PRJNA1269089 and SRA study SRP588338. Searching any of these in the dataset finder brings you back here.

Study design
5 × NPp53 homonally intact biol vs 5 × NPp53T homonally intact biol vs 5 × NPp53 castrated biol vs 3 × NPp53T castrated biol

Supports a between-group comparison across 18 samples.

How we read this: 4 replicated groups read from 19 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.
