Predicting cell wall mechanics from structure in a materials engineering approach to plant growth. The project fosters a novel, interdisciplinary approach to understanding how the structure of plant cell walls determines their mechanical properties.

The project fosters a novel, interdisciplinary approach to understanding how the structure of plant cell walls determines their mechanical properties. Such understanding requires combining biological and engineering approaches and will illuminate how plants grow and produce cells and organs with particular shapes. This is scientifically important but is also important for industries depending on specialised cell shapes such as those of cotton and wood fibres. Our work will improve our understanding of how wall structure determines fibre and other cell shapes and give us tools which can be used to understand how final wall structure determines the fibre mechanics on which industrial users depend.

Summary
The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells ....The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells use epigenetic changes to help control how they grow and develop. Evidence suggests a direct link between diet and environmental influences on our epigenetic profile. Recent research has traced the origins of many of the health problems of adult life back to the earliest periods of development _ to the time spent in the womb and the first few years of life. If we are born with a low birth weight, we are more likely to get sick later in life. Overwhelming evidence exists that the environment in the womb is critical for a healthy birth weight (and health in later life) and it is thought that epigenetics may be the missing link between this environment, low birth weight, and therefore health in later life. In addition, mounting evidence supports a general link between epigenetic de-regulation and predisposition to disease. However, the timing and the overall contribution of environmental- genetic influences to the establishment of faulty epigenetic markings remain largely unknown. Twins are the best model to study this link as they share similar (but not identical environments) and some share identical genetic makeup. Using twins, Dr Jeffrey Craig and his team will investigate the factors in the prenatal environment that modify specific cells, leading to low birth weight and increase disease risk later in life. They predict that this occurs via specific changes in gene activity caused by epigenetic disruption.Read moreRead less

Novel cell wall genes ripe for the picking. This project aims to investigate the role of recently discovered plant cellulose synthase-like CslM genes and to define the polysaccharide product associated with them. Successful identification of the polysaccharide is highly likely to increase our fundamental understanding of how cell walls are made, how cells stick together or fall apart as well as facilitating the training of the next generation of cell wall biologists in challenging molecular and ....Novel cell wall genes ripe for the picking. This project aims to investigate the role of recently discovered plant cellulose synthase-like CslM genes and to define the polysaccharide product associated with them. Successful identification of the polysaccharide is highly likely to increase our fundamental understanding of how cell walls are made, how cells stick together or fall apart as well as facilitating the training of the next generation of cell wall biologists in challenging molecular and biochemical techniques. This new knowledge could increase our understanding of fruit ripening, and how it might be manipulated. This could have significant downstream commercial benefits if applied to breeding programs of economically important fruit such as grapes, tomatoes and strawberries.Read moreRead less

Summary
The Role of Melanoma Tumour Antigen p97 (Melanotransferrin) in Melanoma Tumourigenesis Melanotransferrin (MTf) is a homologue of the iron transport protein, transferrin, and was one of the first well characterised melanoma tumour antigens. Our published studies have shown that MTf plays an important role in melanoma tumourigenesis in vivo. In this proposal, we will assess if it is associated with melanoma progression in patient samples and examine its role in melanoma growth and metastasis.

Summary
Iron is crucial for many essential biological processes. Recently, we demonstrated that iron-depletion can affects important signalling pathways (e.g., JNK and p38) that play important roles in growth arrest and apoptosis. This study is designed to investigate the cellular and molecular effects of iron depletion which currently remains unclear. The research is crucial for understanding: (1) the effects of iron deficiency and (2) for understanding the effects of iron chelators that are used for t ....Iron is crucial for many essential biological processes.

Improving neuronal cell function with cell permeable copper complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs and this information is critical for further drug development. This project will determine how metal-based drugs are metabolised by neuronal cells and how this may result in therapeutic benefit.

While we know much about the electrical properties of dendrites in other species, primarily rodents, little is known about the electrical properties of human dendrites. This project aims to address this gap in knowledge for the first time. The results obtained will shed light on the mechanisms the brain uses to process information, and therefore will bring us a step closer to truly understanding ourselves.Read moreRead less

Summary
The overarching goal of this proposal is to determine the molecular basis for tumour cell dependence on activated ribosomal RNA gene repeats (rDNA). Our working model posits that rDNA repeats become activated through changes in rDNA chromatin structure that include increased binding of the RNA Polymerase I transcription factor UBF.
