Project Details

To really understand embryogenesis and its related diseases it is essential to integrate all levels of gene regulation, i.e. transcriptional control, post-transcriptional mechanisms such as mRNA stability, splicing, and editing, translational control and post-translational modifications. One novel regulatory mechanism is the regulation of gene expression by non-coding RNAs (ncRNAs).

Eukaryotic transcriptome analyses have revealed the presence of a huge number of non-coding RNAs (ncRNAs) with developmentally regulated expression, but little is known about their function. This project will address the genetic mechanisms of these ncRNAs using the differentiation of the bipotential gonad into either testis or ovary as a model system. We are elucidating the function of these non-coding RNAs using a series of in vitro, ex vivo and in vivo studies, integrating cell biology, developmental biology, biochemistry, and mouse genetics.
