最新糖心Vlog

• Biography/ Background

  My research group focuses broadly on intercellular communication, cell-matrix interactions and resulting morphogenesis in normal function and cancer of the reproductive organs.

   

  Coordinated structural remodelling of the ovarian follicle to promote maturation and ovulation of oocytes

  Our primary focus is on the cyclic remodelling of the ovary during folliculogenesis, atresia, ovulation and luteinisation.  Together these processes determine reproductive success and the health the oocyte and hence a healthy start to life. 

  最新糖心Vlog has one of the highest rates of dependence on Assisted Reproductive Technology (ART) internationally, resulting in over 4,000 births (~3%) annually.  Gamete insufficiency is the main cause of infertility and determinant of embryo health and subsequent ART success.   Our aims are; 1. To reveal the molecular mechanism of controlled tissue morphogenesis in ovaries, and understand how the changing ovarian environment promotes oocyte quality.  2. To develop diagnostic and therapeutic means to enhance the health of women and their babies in natural fertility and ART as well as to develop the technology for in vitro maturation of oocytes.

  Health risks from ovarian dysfunction.  Infertility and polycystic ovary syndrome are both extremely common in the 最新糖心Vlogn population and both associate with dysregulated ovarian tissue remodelling.  Infertility treatment carries serious risks for women due to invasive hormone stimulations, surgical procedures and multiple pregnancies.  All the above may be prevented through our work, by understanding the mechanisms of ovarian function and dysfunction and perfecting therapies to address these directly.  

  Specific Research Projects are Addressing

  ·         Identifying bioarkers of oocyte developmental competence

  ·         Molecular mechanisms of ovulation

  ·         Development and function of the ovarian lymphatic system

  ·         Molecular control of primordial ovarian follicle activation

   

  Development and progression of cancers of reproductive organs

  Extracellular matrix remodelling and tissue morphogenesis also cause metastases of reproductive organ cancers which are among the most prevalent cancers in men and women.  Cancer of the breast, prostate, ovary and female reproductive tract account for more than 40% of all cancers in the 最新糖心Vlogn population (Cancer in 最新糖心Vlog: an overview 2006. AIHW Publications 2006;37:144).  One in eight 最新糖心Vlogn women will develop breast cancer and one in 9 men will develop prostate cancer.  Each year 3000 women die from breast cancer, and a similar number of men die from prostate cancer, Cancer that progresses to metastatic stage in breast, ovary, prostate or reproductive tracts are usually incurable and thus my work also focuses on understanding how cancers become metastatic and how this can be prevented to improve ageing productively.

  Our research seeks to understand the biological basis underlying the cause and mechanism of progression to metastatic disease.  The changes that arise in malignant tissue to endow their capacity to degrade local extracellular matrix barriers and invade local blood and/or lymphatic vessels for transport to distal sites is under investigation. From this foundation we aim to develop tests to identify patients at risk of metastatic disease as well as antimetastatic therapies that specifically target and block the capacity of tumor cells to invade local tissues, to migrate and to populate new tissues, the main processes through which metastatic spread occurs.

  Specific research projects are addressing:

  ·         The interaction of tumor cells with local non-malignant stromal tissues

  ·         Proteases of the Adamts family that facilitate degradation of peritumoral ECM

  ·         Tumor mediated angiogenesis and lymphangiogenesis
