Epigenetic reprogramming of development by nutritional factors in honeybee. The project aims to study the mechanism by which a specialised nutrition can change or even reverse the process of adult cell fate. The project will use a previously unexplored method of nutritional reprogramming of imaginal discs in honeybees by royal jelly and identify novel components of both the genetic and epigenetic systems that are most potent as reprogramming factors. The project seeks to improve our understandin ....Epigenetic reprogramming of development by nutritional factors in honeybee. The project aims to study the mechanism by which a specialised nutrition can change or even reverse the process of adult cell fate. The project will use a previously unexplored method of nutritional reprogramming of imaginal discs in honeybees by royal jelly and identify novel components of both the genetic and epigenetic systems that are most potent as reprogramming factors. The project seeks to improve our understanding of how epigenetic remodelling of the information content of the genome contributes to conversion of cell fate in vivo and in vitro. More broadly, the project could potentially establish the honeybee imaginal discs as a model for understanding pluripotency and environmentally controlled developmental plasticity.Read moreRead less

Summary
A chromosome is a grouping of coiled strands of DNA, containing many genes. Every human cell has 23 pairs of chromosomes, which together comprise the genome. Both gain and loss of any of these chromosomes will lead to severe medical problems including birth defects and cancer development. Thus, the understanding of the mechanisms underlying the exact passage of these chromosomes from a parental cell to two new cells during cell division, and how the information is copied from from one cell gener ....A chromosome is a grouping of coiled strands of DNA, containing many genes. Every human cell has 23 pairs of chromosomes, which together comprise the genome. Both gain and loss of any of these chromosomes will lead to severe medical problems including birth defects and cancer development. Thus, the understanding of the mechanisms underlying the exact passage of these chromosomes from a parental cell to two new cells during cell division, and how the information is copied from from one cell generation to another, is an important area of research, however, much remains to be learnt about the mechanisms. Our laboratory was the first to discover a key component of the chromosome that is involved in the regulation of the cell division process, ensuring the accurate segregation of chromosomes. This structure, known as a neocentromere, is an ideal model system to study important aspects of chromosome segregation. The present project proposes to study the properties of this neocentromere in detail. The outcome will contribute to our knowledge on the processes underlying cell and chromosome division, which will ultimately have a direct impact on our understanding of the causes for some of the most common clinical conditions that affect human health.Read moreRead less
HEN1 is a regulator of piRNA metabolism, transcriptional regulation and mammalian male fertility. This project is to define the biochemistry of a previously uncharacterized protein in male fertility using a unique mouse model and innovative DNA and protein technologies. This project will define a novel, and essential, pathway for male fertility and may ultimately have relevance to the maintenance of health or improving fertility.
Ageing and the muscle stem cell niche. Adult stem cells are critical for repair and maintenance of tissues and ageing tissues show reduced stem cell function. This project will focus on how ageing leads to disruption of communication between muscle stem cells and their niche. The project aims to identify new therapeutic targets for age-related muscle wasting and reduced mobility in the elderly.
