Polycomb protein methyltransferase, Enhancer of Zeste 2 (Ezh2), is frequently overexpressed in human malignancy and is implicated in cancer cell proliferation and invasion. Recently, several other polycomb proteins have been implicated in modulating the response to DNA double strand breaks, and...

A large number of exogenous and endogenous agents can result in DNA damage leading to mutagenesis and cell death. A thorough knowledge and understanding about the effects of these agents on different sequences of DNA is important for elucidating the fundamental chemical mechanisms of DNA damage....

Breast cancer is the most common cancer amongst women in Canada. The current treatment regime for early stage breast cancers is breast-conserving surgery with radiation therapy. However, 10-20% of patients develop local recurrence, and some exhibit metastatic spread, which is associated with a...

Novel spectroscopic probes of sunscreens, initial excited-state structural dynamics and DNA photodamage
DownloadSpring 2010
This thesis discusses developing new tools to probe DNA damage resulting from photoinduced chemical processes and probing the initial excited-state structural dynamics of nucleic acids and sunscreen agents. The results of this thesis show that UV resonance Raman spectroscopy (UVRRS) is an...

Investigation of the BRCT repeats in human hereditary breast cancer and DNA damage response
DownloadFall 2009
The C-terminal region of breast cancer susceptibility gene 1 (BRCA1) contains a pair of tandem BRCT repeats that are critical for the tumour suppressor function of BRCA1. BRCT repeats are present in a large of number of proteins that are implicated in the cellular response to DNA damage. A subset...

The DNA damage response (DDR) is critical for maintaining genomic integrity and prevention of genotoxic consequences leading to carcinogenesis. The DDR signaling cascade results either in the activation of the repair pathway, or initiation of apoptosis if the repair is not possible. Many...

Absorption of UV light by nucleic acids can result in the formation of molecular lesions in DNA and RNA, leading to mutagenesis, carcinogenesis, and cell death. In this work, hairpin oligonucleotide probes, which have previously been shown to be selective for DNA damage, are used. The hypochromic...

Drosophila Mage, a component of Smc5/6 DNA response complex, confers resistance to caffeine and genotoxic stress and plays a role in the cell cycle and cell survival
DownloadFall 2014
Over 50 Melanoma-associated antigen (MAGE) genes have been identified in the human genome. They share a conserved 200 amino acid MAGE-homology domain (MHD). In yeast, the only MAGE homolog (Nse3) is a component of the Smc5/6 DNA damage response complex. In humans, MAGE proteins influence cell...
