• Characterization of copy number quiet oral cancer

  Copy number quiet head and neck squamous cell carcinoma are a distinct subset with relatively good prognosis. Previous work has indicated this subset is most commonly found in the oral cavity and is highly enriched for HRAS and CASP8 mutations. TP53 mutations are much less common than in CNA-quiet oral cancers. In this study we corroborate the validity of CNA-quiet tumors as a distinct subset in a large OSCC cohort and further chart clinical, genomic, and immunological characteristics of this subset.

• BE_screens_of_WRN_gene_in_MSI_models

  We will take advantage of a base-editing screening strategy to engineer mutations in the WRN gene by deep mutagenesis. Two MSI-H cell lines sensitive to WRNi will be genetically modified to express doxycycline-inducible ABE and CBE base editors through a knock-in strategy. Moreover, we will design a pooled library of ~4000 gRNAs targeting the WRN gene plus appropriate controls gRNAs. Library-transduced cells will be selected with WRNi to identify WRN mutations able to interfere with the activity of WRNi.

• Multifocal cohort analysis unveils cell types associated with regional lymph node seeding in prostate cancer

  The aim of this project was to assess the effect of intratumor heterogeneity on pathological and molecular markers in locally advanced prostate cancer. We demonstrate how primary lesions with a higher metastatic potential more closely resemble the state in the metastatic lymph nodes, for some biological signatures. Finally, we developed a statistical procedure to identify the most likely seeding lesion and introduced a statistical testing procedure to leverage the intratumor heterogeneity to identify signatures that characterize the seeding lesion.

• Aneurysmal Subarachnoid Hemorrhage patients with or without vasospasm

  Cerebellar vasospasm is a severe complication of aneurysmal subarachnoid hemorrhage (aSAH) occurring for 30% of aSAH patients. To date, no biomarker of vasospasm occurrence exists and thus all aSAH patients undergo a preventive and dangerous treatment. In this study, we explored the miRNome of aSAH patients to detect potential expression differences between the patients developing a vasospasm (VSP+) or not (VSP-). The shared data include raw and normalized count miRNA data in aneurysmal subarachnoid hemorrhage patients with or without vasospasm.

• ENU_LS_411N_TripleTherapy

  BRAF V600E colorectal cancers do not respond to the only currently FDA approved targeted therapy for CRC. There is currently a trial underway in the UK recruiting V600E CRC patients for treatment with a triple therapy combination of Cetuximab, Trametinib and Dabrafenib. We have mutagenized a pool of V600E CRC cell lines and treated with this triple therapy to select out drug resistant clones. We will now sequence these drug resistant clones with the aim of identifying common point mutations engendering resistance to this new therapy.

• Genomewide copy number alteration screening of circulating plasma DNA

  Early cancer diagnosis might improve survival rates. As circulating tumor DNA (ctDNA) carries cancer-specific modifications, it has great potential as a noninvasive biomarker for detection of incipient tumors. We collected cell-free DNA (cfDNA) samples of 1002 elderly without a prior malignancy, carried out whole-genome massive parallel sequencing and scrutinized the mapped sequences for the presence of (sub)chromosomal copy number alterations (CNAs) predictive for a malignancy. When imbalances were detected, 6-monthly clinical follow-up was carried out.

• scRNAseq of human primary nasal epithelium differentiated at air-liquid interface exposed to SARS-CoV2

  The nasal epithelium is a plausible entry point for SARS-CoV-2, a site of pathogenesis and transmission, and may initiate the host response to SARS-CoV-2. Antiviral interferon responses are critical to outcome of SARS-CoV-2. Yet little is known about the interaction between SARS-CoV-2 and innate immunity in this tissue. Here we applied single-cell RNA sequencing and proteomics to a primary cell model of human primary nasal epithelium differentiated at air-liquid interface.
