Summary
The male germ line is a fantastic system within which to define processes of fundamental importance to cell biology and health broadly. Within this grant we will define the role of a poorly described RNA splicing factor in all of stem cell function (spermatogonia), meiosis (spermatocytes) and in the remarkable metamorphosis underlying spermatid maturation. This will be done using a range of phenotypic characterizations, CHIP and RNA Seq technologies and gene sequencing.
The Mechanism Of Spermatid Differentiation - A Link To Tumour Suppression

Summary
To discover novel regulators of male fertility, we have screened libraries of mutant mice generated by a chemical mutagen. This project aims to define the function of the mutated gene identified in a male-specific infertile mutant mouse line. The mutated gene has been proposed to play a role in regulating cell death and suppress lung tumour formation. Our data may reveal novel options for male infertility treatment and for the development of male contraception and lung cancer biomarkers.
A New Model Of Asthenospermia And A Candidate Gene For Multiple Ciliopathies

Summary
Though the analysis of a unique mouse strain (Mot1) we have identified a previously unknown cause of male infertility and lung disease. We hypothesis that the Mot1 line is a model of human primary cilia dyskinesia and that the Mot1 protein is involved in cilia function. Within this project we will define the consequences of a loss of Mot1 protein function, we will define its binding partners and we will screen for mutations in the corresponding human gene.
RNA Binding Protein Musashi: Role In Folliculogenesis And Oocyte Development

Summary
Women in Australian have opted for social and economic reasons to delay both marriage and childbirth. Both infertility and congenital abnormality is associated with advancing maternal age as the ovarian pool of oocytes declines in number and quality. In this project we aim to gain an understanding of the molecular mechanisms underpinning healthy oocyte development. Insights gained have the potential to alleviate miscarriage, infertility and congenital abnormalities in Australian families.
