Research Interest

The research program of my laboratory is focused on:
1) Characterization of novel markers for prostate cancer (PCa)
2) Identification of genes and pathways responsible for progression of PCa
3) Development of new tools and databases

1) Characterization of novel markers for prostate cancer (PCa)

We identified that exosomes (small extracellular vesicles, EVs) are released by cancer cells and contain cytoplasmic proteins and RNAs derived from the cells that produced them. These EVs are therefore considered 'biomarker treasure chests' since their molecular characterization can tell the presence and status of the cancer cells. We have developed an ELISA-like assay (TR-FIA) that can measure these EVs and developed nanobodies against PCa-derived EVs for their specific capture and detection in body fluids.

Using microarray and RNAseq datasets, we identified hundreds of novel RNAs that are only expressed in PCa cells. These transcripts referred to as EPCATs (EMC PCa-associated transcripts) are long noncoding RNAs and perfect diagnostic markers. We are now developing assays to detect EPCATs in urine (EVs) and in biopsies (by in situ hybridization) to test their diagnostic and prognostic value in a clinical setting.

Besides long noncoding RNAs, we also discovered new small RNAs that are derived from tRNAs and snoRNAs. Some of these RNA fragments have diagnostic and prognostic value and are under investigation.

2) Identification of genes and pathways responsible for progression of PCa

 From DNAseq (whole genome and exome sequencing) and RNAseq, we identified many novel fusion genes and genes mutated in PCa. These genes are being analyzed for their function as potential new oncogenes and tumor suppressor genes in PCa. Besides increasing our understanding of cancer progression, these genes might be targets for therapy.

One pathway we have worked on for years is the androgen receptor cascade. The mechanisms by which PCa becomes castration independent remains an important focus of our group.

3) Development of new tools and databases

An essential layer in our research is the constant development and improvement of technologies, model systems, databases and bioinformatics tools.

In collaboration with the department of Bioinformatics and the Cancer Computational Biology Center (CCBC), new software to process DNAseq and RNAseq data is being developed. Various tools to identify novel fusion genes, correct for polymorphisms and proteogenomics pipelines are under construction.

In order to reproduce the progression of PCa in patients, we constantly develop new model systems including tissue slices, patient-derived xenografts, 2D and 3D cell culture systems and therapy-resistant cell lines. Recently, we generated PCa cell lines that are color-coded and genetically barcoded to unravel the process of metastasis.

To further support our ongoing research, we expand and create new databases and biobanks. Extensive efforts are ongoing to sequence fresh frozen and FFPE PCa samples to develop a large dataset for discovery and validation of genes of interest. Biobanks for urine, serum, fresh tissue are expanded to supply the group and collaborators with the materials to move lab discoveries to a pre-clinical validation level.

New techniques and technologies are kept up to date and we invested in the optimization of in situ hybridization, TR-FIA and EVQuant to quantify EVs, nanobody phage display libraries and in vivo imaging technologies.
