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
10 samples: 5 conditions, mostly in duplicateGroups 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)
We have generated various genetically engineered mouse models (GEMMs) of advanced bladder cancer that recapitulate various morphological variants of human tumors, with distinct histological characteristics, differing onset times or growth rates, and varying incidences of dissemination. To investigate the molecular pathways underlying these features, we performed a transcriptomic analysis of these models in comparison with control urothelium.

Given that concurrent TP53 and RB1 alterations are frequently observed in human tumors and are associated with specific molecular subtypes and increased aggressiveness, this study aimed to develop and characterize new models comparing the combined loss of Pten, Trp53, and Rb1 (in an Rbl1-null background, due to functional compensation of Rb1 loss in mouse tissues) with the loss of Pten and Trp53 alone, where the retinoblastoma (Rb) family remains intact. In both models, basal urothelial cells were targeted using adenoviruses expressing Cre unther de control of the Krt5 promoter (Ad5-Krt5-Cre), while luminal urothelial cells were targeted using the murine Krt20 promoter (Ad5-Krt20-Cre). Despite the advantages offered by these GEMMs, their limitations—including unpredictable tumor onset, long latency periods, and difficulties in early tumor detection—led us to develop immunocompetent heterotopic models using tumor cell lines derived from primary tumors arising in GEMMs. These models enable more accurate tumor monitoring and synchronized growth, thereby improving the robustness of preclinical studies. Here, we provide a transcriptomic analysis of some of these bladder tumor-derived cells.

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 GSE302079_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 PRJNA1288480 and SRA study SRP599277. Searching any of these in the dataset finder brings you back here.

Study design
5 conditions, mostly in duplicate
4K5 cell line, ×2 3K20 cell line, ×2 CK5.A cell line, ×2 K5.6 cell line, ×2 CDK20.D cell line, ×2

Supports a between-group comparison across 10 samples.

How we read this: 5 replicated groups read from 10 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.
