Summary
We discovered a novel mechanism linking stress during DNA replication to difficulties with the cell division process, and identified how this turns on DNA damage response signals from the chromosome ends (i.e. “telomeres”). We have further identified that we can exploit this mechanism to kill cancer cells. In this project we will explore this newly discovered mechanism and identify how it can be targeted for therapeutic purposes.

Summary
Apoptosis, or programmed cell death is a powerful defence mechanism against viral infection. Thus, to replicate efficiently viruses have evolved means to inhibit apoptosis. The central aim of this work is to understand how cytomegalovirus prevents cell death protein during infection. The proposed studies will improve our understanding of the mechanisms that regulate viral replication and will contribute insights into the normal processes that control cell survival.
DNA damage response pathways play important roles in preventing the onset of cancer and regulating the clinical response to chemotherapeutics, and some of the relevant proteins have additional functions during normal development. This fellowship will study new a human protein with key roles in the formation of the lung, and its roles in preventing devastating consequences of normal oxidative damage to DNA, as well as additional fundamental mechanisms involved in preventing genome mutations.
