Analysis of the DNA damage response in model systems
(2014-07-24)The integrity of our DNA is constantly threatened by endogenous and exogenous sources of damage. In the absence of sufficient repair mechanisms, this damage can lead to mutations, potentially resulting in the development ... -
Characterisation of novel ATM-interacting factors involved in double-strand break repair
(2012-10-22)Ataxia-telangiectasia (A-T) is a rare human disease characterized by cerebellar degeneration, immune system defects and cancer predisposition. The disease has been the subject of intense scientific scrutiny, particularly ... -
Functional dissection of the Smc5/6 complex: roles of the SUMO ligase Nse2/Mms21 in the maintenance of genome stability
(2011-06)Nse2/ Mms21 is an E3 SUMO ligase component of the Smc5/6 complex, which plays multiple roles in maintaining genome stability. To study the functions of the vertebrate Nse2 orthologue, we generated Nse2-deficient chicken ... -
Regulation and function of the tumour suppressor 53BP1 at sites of DNA damage
(2013-10-16)Cancer is the major cause of death for people in middle age. It results from cell transformation into malignant cells and propagates with normal controls. This process is induced by mutations occurring in DNA through the ... -
The response of mouse mesenchymal stromal cells to radiation-induced DNA double-strand breaks
(2013-12-16)Mesenchymal stromal cells (MSCs) are radio-resistant stem cell progenitors that support haematopoiesis in the bone marrow and contribute to the tumour microenvironment. The mechanisms that drive MSC radio-resistance are ... -
A role for USP9X in homologous recombination repair of DNA double strand breaks
(NUI Galway, 2020-02-11)In order to prevent the deleterious effects of a variety of genotoxic agents, cells have developed complex surveillance mechanisms and multiple DNA repair pathways that allow them to maintain genome integrity. The ... -
The roles of centrins/caltractins at the centrosome and in genome maintenance
(2012-06-21)The principal microtubule-organising centre in animal cells, the centrosome, contains centrin, a small, highly-conserved calcium-binding protein that can be found throughout eukaryotes. Several centrin isoforms exist and ...
