Phenotypic screens for SIRPA expression reveal RAB21 as a general regulator of macrophage surface identity Through CRISPR screening, Granda Farias et al. find results consistent with cis CD47-SIRPA interactions relying on QPCTL and that RAB21/Rab21 inactivation reduces macrophage model surface SIRPA/Sirpa ...

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

Pan-cancer N-glycoproteomic atlas of patient derived xenografts uncovers FAT2 as a therapeutic target for head and neck cancers Cell surface proteins offer significant cancer therapeutic potential attributable to their accessible membrane localization and central role in cellular signaling. Despite this, their promise remains ...

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