CRACKING CANCER ANEUPLOIDY
Our lab focuses on a unique, understudied trait of cancer. Changes in the chromosomal composition of the cell, also known as aneuploidy, make for a fundamental difference between normal and cancer cells. We combine experimental and computational approaches to uncover the basic biology underlying this hallmark of cancer, track its origins and understand its cellular consequences. By doing so, we strive to expand our understanding of the genetic basis of cancer, and to make aneuploidy a therapeutic target for precision cancer medicine.
OUR RESEARCH INTERESTS
Aneuploidy – the presence of an abnormal number of chromosomes in cancer cells — is characteristic of most tumors, and is rarely observed in normal tissues. It is not fully understood how aneuploidy contributes to tumor formation and progression. Moreover, there are currently no therapeutics that target this hallmark of cancer to eliminate tumors. We apply a variety of genomic and functional approaches to studying this phenomenon.
EVOLUTION OF CANCER MODELS
The study of the complex genetics of human cancer depends on reliable cancer model systems. However, these models reflect the biology of actual human tumors only to a certain extent, and they evolve in ways that pose both risks and opportunities for cancer research. We study the genomic stability and evolution of cancer model systems, in order to improve their use in basic research, with an emphasis on aneuploidy research.
STEM CELLS & CANCER
Human stem cells share fundamental characteristics with human cancer cells, and thus make for a unique model system for the study of cancer genetics. We use human stem cells as a tool for aneuploidy research, taking advantage of their inherent chromosomal instability and of their amenability to genome editing. We also use human stem cells as a tool for the identification of cancer vulnerabilities.
OUR BIG QUESTIONS
WHAT DRIVES ANEUPLOIDY IN CANCER? HOW DOES ANEUPLOIDY CONTRIBUTE TO THE INITIATION AND PROGRESSION OF TUMORS?
WHAT CELLULAR VULNERABILITIES ARE INDUCED BY ANEUPLOIDY? HOW CAN ANEUPLOIDY BE EXPLOITED TO KILL CANCER CELLS?
WHAT ARE THE IMPLICATIONS OF GENOMIC EVOLUTION FOR CANCER MODELING? HOW CAN CANCER MODEL SYSTEMS BE IMPROVED?
