HEN1 is a regulator of piRNA metabolism, transcriptional regulation and mammalian male fertility. This project is to define the biochemistry of a previously uncharacterized protein in male fertility using a unique mouse model and innovative DNA and protein technologies. This project will define a novel, and essential, pathway for male fertility and may ultimately have relevance to the maintenance of health or improving fertility.

Summary
How mammalian males indirectly control transmission of paternal traits. This project aims to address how environmental insults in males prior to conception are able to modify phenotype of subsequent offspring. This project expects to generate fundamental knowledge in a key biological pathway on how non-genetic factors delivered by sperm at conception are able to program the growth of the developing embryo.The knowledge generated from this project will provide understanding and biological options ....How mammalian males indirectly control transmission of paternal traits. This project aims to address how environmental insults in males prior to conception are able to modify phenotype of subsequent offspring. This project expects to generate fundamental knowledge in a key biological pathway on how non-genetic factors delivered by sperm at conception are able to program the growth of the developing embryo.The knowledge generated from this project will provide understanding and biological options for responding to, and potentially mitigating the impacts of environmental change on the mammalian reproductive system.Read moreRead less
Ancestral, conserved and novel mechanisms in marsupial genomic imprinting. Genomic imprinting is the differential expression pattern of some genes depending on whether the gene copy came from the mother or the father. This differential expression is essential for embryonic development and errors lead to disease. To date, most of our knowledge of the control of genomic imprinting comes from the mouse, but much less is known about this process in marsupials. Our comparative approach, using marsupi ....Ancestral, conserved and novel mechanisms in marsupial genomic imprinting. Genomic imprinting is the differential expression pattern of some genes depending on whether the gene copy came from the mother or the father. This differential expression is essential for embryonic development and errors lead to disease. To date, most of our knowledge of the control of genomic imprinting comes from the mouse, but much less is known about this process in marsupials. Our comparative approach, using marsupial mammals that are distantly related to mice and humans, aims to clarify how genomic imprinting mechanisms have evolved, which patterns are conserved across mammals, and which vary. Our proposed research aims to provide new approaches and understanding of this fundamental process essential for the continuation of life.

Reprogramming maternal and paternal genomes during development: new perspectives from marsupials. This project will use marsupials to examine programming of the germ cell lineage (cells that become eggs and sperm) and the evolution of these mechanisms that control their development. Using the unique features of our Australian native animals, this research will contribute to the understanding of the transmission of life.
