Nuclear architecture is critical to the preservation of genome integrity. The aim of this research proposal is to delineate the role of chromatin organisation in transcription factor target search and damage site recruitment of DNA repair factor machinery. To achieve this I have developed fluorescence microscopy methods to monitor changes in chromatin structure with submicron resolution. Only with this technology can I determine how chromatin dynamics maintain genome integrity or induce disease.
Female fertility and age at menopause are determined by the number and quality of eggs stored in the ovaries. For unknown reasons, two-thirds of all eggs die soon after they are made. Furthermore, a serious side effect of cancer treatment is egg death resulting in infertility and early menopause. I am unravelling the genes involved in determining whether an egg will live or die. This understanding will help us develop novel strategies to preserve fertility during aging and cancer treatment.
Modulating Skin Regenerative Responses To Improve Wound Repair And Fight Carcinogenesis

Summary
Skin disorders, such as hard to heal wounds or the most common skin cancers, are a major burden on the national health system. Despite their different nature they employ similar mechanisms of response to injury. In this project we intend to develop a comprehensive understanding of the genetic and molecular mechanisms at play to allow clinical interventions to prevent or to cure these disorders.
Coordination Of The Fanconi Anemia Pathway To Maintain Genome Stability

Summary
Fanconi anaemia is a heritable disorder where bone marrow failure occurs on average at age seven and is the major cause of death at around age 20. Many patients also develop leukaemia, representing another overwhelming hurdle in their youth. The incorrect function of any one of 19 proteins can lead to Fanconi anaemia. We will search for a drug that can compensate for the absence of one of these proteins to allow correct function of the other proteins offering possible leads for treatment.
Cellular Mechanisms Underlying Neurodegenerative Disease And The Neuronal Response To Trauma

Funding Amount

Summary
Brain and spinal cord injury are major causes of death and disability, with degenerative diseases similarly affecting large proportions of the population. The singular objective of my research proposal is to increase our understanding of the molecular and cellular processes by which nerve cells respond to trauma and diseases such as Alzheimer’s and Parkinson’s, and to identify new therapeutic approaches aimed at encouraging the repair of damaged cells.
