Epigenetic Regulation Of Cell Lineage Differentiation In The Early Embryo

Funding Amount

Summary
Exposure of embryos to a range of stresses can increase the predisposition to chronic diseases of adulthood. Stressing embryos at critical stages of development cause errors in reorganization of the nucleus that are required for normal gene expression. These errors are propagated into adulthood. This project will map the normal processes of nuclear reorganization and define how stress to the embryo changes this process, allowing an understanding of the causes of some important chronic diseases.
Epigenetic Reprogramming Within The Pluripotent Lineage Of The Early Embryo

Summary
Cells of the early embryo have the remarkable capacity to form all of the different tissues and organs in the body. This property requires re-organisation of the embryo’s genetic material in a manner analogous to re-booting a computer. This project will define the properties of this rebooting process. This information will allow much better strategies for building spare parts for regenerative medicine and provide the information required to reduce the incidence of inborn defects.
Role Of Snail Family Proteins In Male Fertility And Testicular Cancer

Summary
Male fertility requires production of healthy sperm in the testis. This project builds on our discoveries that testicular cells regulate gene activity via the Snail family of proteins during sperm development, and that interruption of their activities reduces fertility in mice and fruitflies. Snail proteins are also active in cancer cells. We propose to study the precise steps in sperm production affected by Snail proteins and how they affect the progression of testicular cancer.
Much of our current knowledge on development of external genitalia (ExG), the penis and clitoris, comes from 20 &70 year-old studies (1); but with significant developments in contemporary imaging and new mouse models, we have new data. The overall goal of this project is to prove the hypothesis that penile and clitoral development is estrogen- (and androgen-) dependent and, to show that the administration of exogenous endocrine disrupting chemicals that alter the balance between estrogen and and ....Much of our current knowledge on development of external genitalia (ExG), the penis and clitoris, comes from 20 &70 year-old studies (1); but with significant developments in contemporary imaging and new mouse models, we have new data.
