Urological CarcinomasScientific focus
Our research group focuses on the study of two common urological malignancies, clear cell renal cell carcinoma and urothelial carcinoma. The application of genomic technologies to the study of cancer continues to revolutionise our understanding of the genetic complexity and heterogeneity of human tumours. A major challenge is to convert this genetic information into biological understanding, as well as to develop individualised therapies that are specific for the mutations that are present in each patient’s tumour.
We study the entire process of tumour formation, beginning with the molecular and cellular mechanisms that underlie the breakdown of normal epithelial proliferative homeostasis, the evolution of tumour cells and parallel evolution of the tumour microenvironment, as well as the process of metastasis. Our major experimental approach is to generate accurate autochthonous mouse tumour models using conventional mouse genetics (Höfflin et al. Nature Communications, 2020; Harlander et al. Nature Medicine 2017; Gonçalves et al Nature Communications 2017, Schönenberger et al. Cancer Research 2016, Guinot et al. Journal of Pathology, 2016, Lehmann et al. JASN, 2015)), as well as novel genetic systems that we have developed (Albers et al. JCI, 2015, Brandt et al. Oncotarget 2018) and continue to develop. We apply advanced analyses such as RNA sequencing, single cell RNA sequencing, exome sequencing, genome-wide epigenetic analyses, metabolomics, in vivo imaging tools and multi-parametric fluorescence microscopy to our tumour models to gain a broad understanding of disease processes. Through collaborations with pathologists we analyse the genetic and cellular composition of human tumours to gain insights into the biology of these diseases as well as to guide our functional genetic and pre-clinical translational studies.
From the therapeutic perspective, we conduct pre-clinical studies to attempt to uncover specific vulnerabilities of cancer cells that are dictated by their underlying mutational genotype and their microenvironment. We identify synthetic lethal gene-drug interactions to discover mutation-specific therapeutic targets and are investigating novel therapeutic interventions that aim to disrupt tumour and immune cell signalling crosstalk with the aim of improving immune checkpoint therapies.
Key words: clear cell renal cell carcinoma, urothelial carcinoma, mouse cancer models, tumour suppressors, epigenetics, signal transduction, immune microenvironment, mutation-specific cancer therapies
