Adaptive Evolution of BRCA1 in Ancestral Mammals. This project investigates adaptive evolution of BRCA1 in the early radiation of mammals. We will test the hypothesis that the evolution of mammary glands and X chromosome inactivation has resulted in modification of the BRCA1 protein sequence as it aquired new roles in these processes. We will also investigate the importance of these changes inducing compensatory changes in other parts of the protein.
New functions for bioactive flavonoids in plants and mammals. We have discovered natural products with biological activity in plants and mammals. These molecules affect plant shape and development and the process of mammalian blood vessel formation. We seek to understand how these molecules work. More understanding is required before one can begin to utilise these molecules for possible beneficial agriculture or human health outcomes. Plant shape influences such things as yield or more drought-r ....New functions for bioactive flavonoids in plants and mammals. We have discovered natural products with biological activity in plants and mammals. These molecules affect plant shape and development and the process of mammalian blood vessel formation. We seek to understand how these molecules work. More understanding is required before one can begin to utilise these molecules for possible beneficial agriculture or human health outcomes. Plant shape influences such things as yield or more drought-resilient root systems. Importantly, we have discovered specific molecules that either promote or inhibit blood vessel formation. A better understanding of how these molecules work could lead to novel treatments for cancer or cardiovascular disease.Read moreRead less
Discovery of novel microRNA biogenesis and functional components. Discovery of novel microRNA components will provide new strategies for confronting a diverse array of challenges Australia faces, such as the increasing rates of certain cancers in our population, to stresses on our crop plants faced with environmental changes. The biological mechanisms underlying these disparate problems are unified by microRNA involvement in many instances. By finding microRNA controlling factors common to all h ....Discovery of novel microRNA biogenesis and functional components. Discovery of novel microRNA components will provide new strategies for confronting a diverse array of challenges Australia faces, such as the increasing rates of certain cancers in our population, to stresses on our crop plants faced with environmental changes. The biological mechanisms underlying these disparate problems are unified by microRNA involvement in many instances. By finding microRNA controlling factors common to all higher organisms, we expect our community will benefit from the increased knowledge base that will help our researchers adopt new strategies in fighting diseases and improving our agricultural industry.Read moreRead less
