Our research program in comparative functional genomics and bioinformatics focuses on gene and bioactives discovery in the mammary gland exploiting the unique lactation strategies of the tammar wallaby, fur seal, echidna and platypus as model systems to better understand mammary gland development and function. We are particularly interested in the central role of milk in early postnatal nutrition as a critical factor that impacts not only on the immediate wellbeing and growth of the newborn but has subsequent and significant influence on adult health, particularly the incidence of mature onset disease (diabetes, hypertension, obesity etc) in adult life. The signals for these developmental clocks are delivered at specific times during the early stages of development and any perturbation of this process can have substantial flow on effects for immediate and long term health. The research program underpins the development of the Geelong Human Milk Bank and Research Centre. The function of the milk bank will be collection, treatment and dispensing of human milk for either premature babies, babies born small for age or any baby at risk where the mother cannot provide enough breastmilk. The research program will identify milk factors that regulate growth and development of the baby and procedures for processing the milk to ensure retention of these factors. This program will broaden to examine the effects of disease on breastfeeding, and in the longer term will include a breastfeeding clinic for consultation and research on clinical problems associated with breastfeeding. The milk bank will have a regional focus in delivering a service to the Geelong hospital but have a national and international focus with the research programs.
The research platform is comprised of microarray, bioinformatics, proteomics, metabolomics, molecular and cell biology, and captive colonies of tammar wallabies and opossums. The milk bank will have a processing laboratory for treatment of milk prior to dispensing to the hospital.
Specific research targets include regulation of mammary cell fate by milk factors and non-coding RNA, endocrine and autocrine control of milk protein gene expression, the role of milk in regulating growth and development of the young, mature onset disease, stem cells in milk and milk proteins with the potential to regulate human breast cancer growth and metastasis.
