Old genes learning new tricks: characterising regulatory changes driving increased heart complexity during vertebrate evolution. The heart has dramatically increased in morphological complexity during vertebrate evolution but the molecular basis driving these major changes remains unknown. Using comparative genomics approaches, this project will explore changes in the regulation of genes involved in heart formation that lead to changes in cardiac structure. It will elucidate for the first time t ....Old genes learning new tricks: characterising regulatory changes driving increased heart complexity during vertebrate evolution. The heart has dramatically increased in morphological complexity during vertebrate evolution but the molecular basis driving these major changes remains unknown. Using comparative genomics approaches, this project will explore changes in the regulation of genes involved in heart formation that lead to changes in cardiac structure. It will elucidate for the first time the cardiac regulatory repertoire in zebrafish and will compare it with that of fly and mouse using cutting-edge bioinformatics pipelines. This work will unravel cardiac-specific regulatory modifications that give rise to evolutionary changes. On a broader scale, it will shed new light on the role of regulatory innovations over gene innovations in the emergence of new traits.Read moreRead less
Molecular dissection of the functional regions of genes that encode actinins (ACTN2 and ACTN3) and their contribution to normal variation in skeletal muscle function. The project has discovered a common genetic variant that affects skeletal muscle structure, function and metabolism and influences athletic ability, and response to diet and exercise. The project will study how this gene influences muscle bulk and strength, the metabolic efficiency of muscle and the risk of obesity in the general ....Molecular dissection of the functional regions of genes that encode actinins (ACTN2 and ACTN3) and their contribution to normal variation in skeletal muscle function.
