Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this ....Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less
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.
The genetic regulation of organogenesis: endoderm development in the Drosophila embryo. Embryonic development is an important research field in biology, not only for its extraordinary complexity but also because of the insights it provides into molecular processes that underpin a variety of diseases. This project aims to discover genes and molecules that regulate the normal development of one of the most important organs, the gut.
Genetic control of spermatogenesis: defining the role of SOX3 in spermatogonial progenitor cells. The transcription factor (TF) SOX3 is a key regulator of neural stem/progenitor cells. Recently, this project has also shown that SOX3 is active in sperm progenitors (spermatogonia) and is required for spermatogenesis. Using our Sox3 KO mouse model and extensive expertise in spermatogonial cell culture, ChIP-seq technology and bioinformatics, this project will investigate crucial aspects of SOX3 fun ....Genetic control of spermatogenesis: defining the role of SOX3 in spermatogonial progenitor cells. The transcription factor (TF) SOX3 is a key regulator of neural stem/progenitor cells. Recently, this project has also shown that SOX3 is active in sperm progenitors (spermatogonia) and is required for spermatogenesis. Using our Sox3 KO mouse model and extensive expertise in spermatogonial cell culture, ChIP-seq technology and bioinformatics, this project will investigate crucial aspects of SOX3 function in the testes including stem versus progenitor cell activity and genome-wide target gene regulation. These studies will uncover the molecular and cellular mechanism by which SOX3 controls spermatogenesis and provide unique insight into how a single TF controls context-dependent differentiation in sperm versus brain progenitor cells.Read moreRead less
