Short description

Research on oncogenic signalling and therapeutic interventions in solid cancer.

Research summary

We have a longstanding interest in studying cooperative genetic alterations that perturb cell cycle restriction and program malignant transformation. Accordingly, we have developed the experimental models in which specific genetic alterations can be investigated in isogenic contexts.

In addition, we have used genetic tools (short hairpin RNA, CRISPR and open reading frame libraries) to identify and study oncogenes, cancer pathways and related targets. By applying these tools or methods, we are in the process to study and identify genes/molecules involved in tumorigenesis, tumor maintenance, and drug sensitivity or resistance.

Over the past several years, we have been particularly interested in using these approaches to identify synthetic lethal partners to oncogenes and tumor suppressors. In particular, we are focusing on oncogenic ras and its effector pathways. We identified several candidates that appear critical for cancer cells harboring oncogenic ras to survive. Currently, we are expanding and extending our initial studies into more complex experimental models that recapitulate further aspects of human cancers.

Research tools and resources

We are using primary and tumor cell lines, 3D/organoids as well as xenograft and genetically modified mouse models for cancer biology studies. A range of cellular and molecular biological techniques are being employed.
