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
12 samples: 3 × BBN_bladder, WT, 16w vs 3 × BBN_bladder, PLD2-KO, 16w vs 3 × TAMs, WT, vs 3 × TAMs, PLD2-KO,Groups 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 tumor microenvironment (TME) modulates therapeutic response and prognosis in patients with bladder cancer (BC). The roles of two phospholipase D (PLD) isoforms, PLD1 and PLD2 (hydrolysis of phosphatidylcholine to phosphatidic acid) in cancer cells have been well-studied in numerous cancer types, but their roles in the TME remain unclear.

We used a mouse BC Pld2-knockout carcinogenesis model and global transcriptomic analysis to reveal that PLD2 was significantly involved in BC progression through immunosuppressive pathways in the TME. We therefore focused on PLD2 and tumor-associated macrophages (TAMs), which were increased in Pld2-knockout mice and further associated with poor prognoses in BC patients. In vitro, we found that Pld2- knockout mouse TAMs had significantly enhanced proliferation, correlating closely with increased IL-1β production. These results indicate that PLD2 suppresses BC progression by regulation of IL-1β secretion from TAMs in the TME, suggesting that PLD2 could serve as a potential therapeutic target for BC.

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 GSE271595_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 PRJNA1132267 and SRA study SRP518209. Searching any of these in the dataset finder brings you back here.

Study design
3 × BBN_bladder, WT, 16w vs 3 × BBN_bladder, PLD2-KO, 16w vs 3 × TAMs, WT, vs 3 × TAMs, PLD2-KO,

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 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.
