Mechanism of higher-order chromatin formation and its role in controlling gene expression. The organization of genomic DNA into chromatin has solved one of the most difficult engineering problems required for the development of a multicellular organism; the compaction of over two meters DNA into a cell almost one millionth this size. Importantly, this compaction of the genome into chromatin has also been exploited by the cell to regulate the expression of genes. The aim of this investigation is ....Mechanism of higher-order chromatin formation and its role in controlling gene expression. The organization of genomic DNA into chromatin has solved one of the most difficult engineering problems required for the development of a multicellular organism; the compaction of over two meters DNA into a cell almost one millionth this size. Importantly, this compaction of the genome into chromatin has also been exploited by the cell to regulate the expression of genes. The aim of this investigation is to elucidate how genes are assembled into complex active or inactive chromatin structures by employing a novel in vitro system. This information will have important implications for gene therapy strategies.

The Dynamic Control of Chromatin Structure. A human chromosome is a highly heterogeneous global structure because along its axis, it folds to different extents to form either highly compacted domains that repress the expression of genes or less condensed regions that enable genes to be turned on. Changes to the structure or stability of chromosomes, and the corresponding alterations to gene expression, have been linked to many diseases states like defects in human development and cancer. This s ....The Dynamic Control of Chromatin Structure. A human chromosome is a highly heterogeneous global structure because along its axis, it folds to different extents to form either highly compacted domains that repress the expression of genes or less condensed regions that enable genes to be turned on. Changes to the structure or stability of chromosomes, and the corresponding alterations to gene expression, have been linked to many diseases states like defects in human development and cancer. This study will uncover the underpinning mechanism of how our chromosomes are organised into distinct functional domains, which may offer the potential to develop new strategies to correct chromosomal abnormalities.

Expression and characterisation of nutrient transporters from the intracellular malaria parasite, Plasmodium falciparum. The malaria parasite invades the red blood cells of its host and this provides it with a safe haven in which to grow and replicate. Within the red blood cell, the parasite takes up nutrients and excretes metabolic wastes via specialised membrane transport proteins which are, as yet, very poorly understood. The sequencing of the malaria parasite genome has enabled us to ident ....Expression and characterisation of nutrient transporters from the intracellular malaria parasite, Plasmodium falciparum. The malaria parasite invades the red blood cells of its host and this provides it with a safe haven in which to grow and replicate. Within the red blood cell, the parasite takes up nutrients and excretes metabolic wastes via specialised membrane transport proteins which are, as yet, very poorly understood. The sequencing of the malaria parasite genome has enabled us to identify candidates for a wide variety of these proteins. The aim of this project is to establish systems in which the functional properties of these transporter proteins may be characterised in detail.Read moreRead less

To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its phenotype. By studying the effects of Cyp genes on fly survival, Cyp gene expression and regulation, and expressing selected Cyp genes in a yeast expression system, we will enhance our understanding of Cyp gene function and evolution.Read moreRead less
Identification of transcription factor genes involved in the regulation of aspects of photosynthetic capacity in plants. There is increasing evidence to suggest that we may be reaching a yield plateau with many agricultural plants and that future avenues for yield increases may depend on increases in photosynthetic capacity per unit leaf area. Molecular genetic technology offers the promise of the direct manipulation of photosynthetic gene expression to increase photosynthetic capacity. This pro ....Identification of transcription factor genes involved in the regulation of aspects of photosynthetic capacity in plants. There is increasing evidence to suggest that we may be reaching a yield plateau with many agricultural plants and that future avenues for yield increases may depend on increases in photosynthetic capacity per unit leaf area. Molecular genetic technology offers the promise of the direct manipulation of photosynthetic gene expression to increase photosynthetic capacity. This project aims to understand one important part of genetic regulation, the transcription factors, that may determine aspects of photosynthetic capacity. Altered expression of these transcription factors in transgenic plants will be used to test the their ability to control photosynthesis and generate agricultural intellectual property.Read moreRead less
