We analyse single-cell sequencing data to investigate tumour evolution from individual cells.
Metastasis results from the dissemination of cancer cells from a primary tumour to other anatomical sites and is the most common cause of death for lung cancer patients. Thus, elucidating genetic changes which engender metastatic potential could have a critical clinical impact. Despite being the primary cause of death for cancer patients, the genomic evolutionary history of metastasis and the genetic causes of this process are poorly understood.
Pioneering recent听studies have demonstrated that multi-site DNA sequencing allows us to investigate the metastatic migration process.听In particular, such data have been used to evaluate the presence of monoclonal vs polyclonal migrations, and to identify candidate driver mutations for metastasis. However,听previous analyses have been affected by some major limitations which may hinder additional mechanisms of metastatic progression and limit their applicability.
Our lab focuses on the design and development of computational methods to analyse and reconstruct metastatic migrations patterns. Specifically, we design approaches to leverage and integrate multiple sources of information from different data and different kinds of somatic mutations.
