Summary (written by the submitters)
We have discovered a previously uncharacterized tumor suppressor function of Numb in the homeostasis of the normal bladder mucosa. Targeted ablation of Numb in the basal layer of the urothelium drives spontaneous bladder tumorigenesis, driving progression from preneoplastic to preinvasive and overtly invasive tumors, and accelerates tumorigenesis in the presence of oncogenic insults.

Using 3D-Matrigel organoid cultures to recapitulate bladder tumorigenesis in vitro, we found that Numb deficiency enhances the proliferative and invasive potential of both mouse and human bladder cancer cells. Integrative transcriptomic and functional analyses revealed that downregulation of the canonical Hippo pathway, resulting in enhanced YAP transcriptional activity, underlies the biological aggressiveness of Numb-deficient bladder cancer. These molecular events are dependent on the activation of RhoA/ROCK signaling subsequent to Numb loss. Thus, a dysfunctional Numb–RhoA/ROCK–Hippo/YAP regulatory network is at play in aggressive Numb-deficient bladder cancers, opening avenues for the development of targeted therapies. Furthermore, retrospective cohort studies revealed that a Numb-deficient status correlates with worse overall survival in post-cystectomy muscle-invasive bladder cancer (MIBC) patients and increased risk of progression to MIBC in non-muscle-invasive bladder cancer (NMIBC) patients. The Numb-deficient status was associated with a 27-gene prognostic signature that has the potential to identify high-risk NMIBC patients who are eligible for targeted RhoA/ROCK/YAP therapies.

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 GSE256272_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 PRJNA1078848 and SRA study SRP490811. Searching any of these in the dataset finder brings you back here.
