Understanding the basis of cooperative behaviour is a major challenge to biological and social science. Our ability to deal with problems such as global warming and the rapid loss of biodiversity, will depend upon an unprecedented level of cooperation between individuals and countries. Our work will use an animal model that shares a number of key characteristics with the societies of our early human ancestors to explore, through experiments and detailed molecular analysis, the basis of cooperative interactions between individuals. This work will uncover the key principles that drive the evolution of cooperation in society and will help us to understand the basis of one the most important components of human nature.Read moreRead less

Summary
Endometriosis is a common disorder affecting up to 10% of women. In this condition, a special type of tissue that normally lines the inside of the womb (the 'endometrium') starts to grow outside the womb, mostly in the pelvis (lower abdomen). Common symptoms are severe pelvic pain, menstrual problems and infertility. The disease has a major impact on women's health, relationships, productivity and life choices. The mechanisms that cause endometriosis are not well understood. Genetic factors infl ....Endometriosis is a common disorder affecting up to 10% of women. In this condition, a special type of tissue that normally lines the inside of the womb (the 'endometrium') starts to grow outside the womb, mostly in the pelvis (lower abdomen). Common symptoms are severe pelvic pain, menstrual problems and infertility. The disease has a major impact on women's health, relationships, productivity and life choices. The mechanisms that cause endometriosis are not well understood. Genetic factors influence a woman's risk of developing endometriosis and finding genes and pathways leading to this disease would be a major advance. This will help design better approaches for the diagnosis, prevention and treatment of endometriosis. Since 1996, nearly 4,000 women with endometriosis plus their families have joined our genetic study. This includes around 1,000 families with two or more sisters who both have the disease. We have looked at the DNA from these sisters and found significant evidence for a gene or genes affecting endometriosis on one chromosome. No one else has linked this location with endometriosis. We are now focusing our efforts in the laboratory on this area, which contains approximately 250 genes. The aim of our new project is to study genes in the region in more detail to pinpoint the gene or genes responsible for risk of endometriosis.Read moreRead less
Perceptual suppression mechanisms in the Drosophila brain. This project will investigate common processes underlying three means to losing conscious perception: selective attention, sleep and general anaesthesia. By studying these suppression mechanisms in a genetic model, the fly Drosophila melanogaster, fundamental processes will be highlighted that are required in the brain for maintaining perception in general.
Evolutionary analyses of short-read sequences from pooled samples. This project aims to provide biologists with a means of making sound, statistical inferences about evolution by using next-generation data from mixed samples. When biologists make statements about history, they use evolutionary trees, frequently reconstructed from the genetic data of many individuals. Next-generation sequencing provides large amounts of genetic data at low cost, but biologists have difficulty using these data for ....Evolutionary analyses of short-read sequences from pooled samples. This project aims to provide biologists with a means of making sound, statistical inferences about evolution by using next-generation data from mixed samples. When biologists make statements about history, they use evolutionary trees, frequently reconstructed from the genetic data of many individuals. Next-generation sequencing provides large amounts of genetic data at low cost, but biologists have difficulty using these data for evolutionary research, particularly when they sample mixtures of DNA from many individuals. The anticipated value of this project is that it allows evolutionary biologists to capitalise on the benefits of next-generation sequencing, without sacrificing their ability to make reliable inferences about history.Read moreRead less

Functional epigenomics interrogation of DNA methylation dynamics during vertebrate development and evolution. DNA methylation (mC) is an epigenetic signal essential for the maintenance of correct gene expression patterns. To investigate the causal relationships between mC and transcription during vertebrate embryonic development and evolution, this project will perform high-resolution mC profiling at different stages of teleost, amphibian and mammalian development.

DNA methylation (mC) is an epigenetic signal essential for the maintenance of correct gene expression patterns. To investigate the causal relationships between mC and transcription during vertebrate embryonic development and evolution, this project will perform high-resolution mC profiling at different stages of teleost, amphibian and mammalian development. Highly conserved and syntenic, methylated sequences will then be used as baits in proteomics screens to identify novel 5mC 'readers'. The generation of genomic profiles of mC 'readers' and their integration with developmental mC maps will reveal transient epigenome dynamics during vertebrate embryogenesis and provide new insights into the conservation of these crucial developmental mechanisms.Read moreRead less

Unique epigenetic states in plant stem cell niches for safeguarding genome integrity. Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells.

Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells. Therefore, it is critical that stem cells defend against attacks that may damage the genome. A unique epigenetic state in plant stem cell niches has been discovered that may protect the genome from damage due to parasitic DNA elements. Using sophisticated genomics, genetics, and cellular technologies, this project will investigate how stem cell epigenetic state is linked to genome defence, how environmental stresses can disrupt the defence system, and the role of the system in driving new genetic diversity. This knowledge is of high importance as agricultural crops enter an era of increasingly challenging conditions.Read moreRead less

Summary
Traffic on DNA: interplay between RNA polymerases and DNA-bound proteins. The DNA inside the cell is not just a repository of information, but is an active player in how that information is used. Proteins bind to defined locations on the DNA to control which genes are active, and genes are expressed by RNA polymerases that track along the DNA. Collisions between RNA polymerases and DNA-bound proteins can remove the proteins or block the polymerase. How can these essential processes safely coexis ....Traffic on DNA: interplay between RNA polymerases and DNA-bound proteins. The DNA inside the cell is not just a repository of information, but is an active player in how that information is used. Proteins bind to defined locations on the DNA to control which genes are active, and genes are expressed by RNA polymerases that track along the DNA. Collisions between RNA polymerases and DNA-bound proteins can remove the proteins or block the polymerase. How can these essential processes safely coexist on the DNA? The project aims to integrate systematic experiments using well-defined genetic components and mathematical modelling to understand the 'design' features of DNA and proteins that minimise these traffic problems. A better understanding could inform new strategies for manipulation of gene expression.Read moreRead less
