Interestingly, the urinary proteome of Black patients harboured more features of aggressive cancers than those of grade- and PSA-matched White patients. These observations highlight the importance of controlling for ancestry-associated differences in biomarker development.

This cohort was stratified by ancestry – thought to be a risk-factor for aggressive disease. We found surprisingly large differences and dysregulation of immune pathways.

After nearly 15 years of urine proteomics of prostate cancer patients, this is our most comprehensive work to date. We generated spectral libraries from hundreds of samples to rapidly analyze 329 post-DRE urines.

Last paper for 2024. Nice work by PDF Matt Waas on proteomics of HNSCC tissues to identify novel biomarkers within the N0 population. Great collaboration with Laurie Ailles
and support from many colleagues Princess Margaret Cancer Centre

Definitely also expressed in skin.

It gets upregulated in squamous carcinomas and is required for growth and survival

There is expression in the cerebellum for sure.
Might be through that route
Not sure how it gets into milk. Maybe low level expression in some mammary epithelial populations. I will look at our own CSF, urine and normal mammary populations tomorrow.

Actually most datasets correlate reasonable well for Fat2. Since I have worked on this protein for the last 8 years

Let us know your thoughts

As mentioned a large number of colleagues contributed to this work, most importantly the project was led by a fantastic PhD student Meinusha Govindarajan and a research associate Salvador Mejia-Guerrero.

The entire data will be evaluable as a searchable web-interface (Glyco PDXplorer).

Fat2 deletion leads to regulation of surface architecture and integrin-PI3K signaling. Finally we raise a highly specific Fat2 antibody which we repurposed into a CAR T construct for proof-of-concept preclinical evaluation.

We discover Fat2 as a novel head and neck cancer surface antigen that has minimal expression in normal human tissues, is essential for tumour grown in vitro and in vivo and high expression is associated with poor survival

We developed a discovery pipeline that utilizes N-glycoproteomics in PDX models to discover novel cancer specific surface antigenes. We initially focus on head and neck cancers and combine our data with patient tumours and cell surface capture

Big effort (> 7 years) from a large number of colleagues. Finally on BioRxiv and to be submitted in January
