Electronic Thesis and Dissertation Repository
Genome instability is an enabling characteristic of cancerous cells. It has recently been discovered that the retinoblastoma protein (pRB), typically known for its role in cell cycle regulation, also aids in the maintenance of genome stability. Intriguingly, mutations to the pRB gene, RB1, can arise late in tumorigenesis in cancer cells whose cell cycle regulation is already compromised by another mutation. This suggests that pRB’s functions in genome stability could underlie cancer relevant characteristics that are independent of its ability to negatively regulate proliferation. The overall aim of this thesis is to characterize the different means through which pRB …
