DNA is a detailed layout of instructions for cellular function. The integrity of human DNA is constantly challenged by a barrage of exogenous and endogenous sources. A regime of genome stability maintenance has evolved to repair the many different types of DNA damage. A form of communication...

Asf1 is a conserved H3/H4 histone chaperone with multiple functions in chromatin modulation. Using budding yeast as a model, we identify new pathways of Asf1 function, and expand current knowledge regarding the known roles of Asf1. First, we uncover novel genetic interactions between ASF1 and...

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

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...

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...

Investigation of the role of UBE4B ubiquitin ligase in p53 regulation in response to DNA damage in ATM-proficient and ATM-deficient cells
DownloadFall 2017
The tumour suppressor protein p53 maintains genomic integrity by coordinating the DNA damage response, which includes growth arrest, DNA damage repair, and apoptotic cell death. p53 is mutated in more than 50% of human cancer, which reflects its importance. The complex mechanism that controls the...

Chromatin structure is important aspect of transcriptional regulation. Replication-coupled (RC) nucleosome assembly is the process of depositing newly synthesized H3-H4 onto nascent DNA behind the replication fork, mediated by the histone chaperones Asf1, CAF-1, and Rtt106. The experiments...
