Our laboratory studies mechanisms of gene regulation that drive sex determination and the development of embryonic gonads using mouse as a model system to identify and understand the underlying cause of disorders of sex development in humans.
One of the most amazing biological processes is the development of a fertilized egg into a complex organism. It involves the orchestration of cellular processes, which is controlled by a delicate network of gene regulation. Disturbance of this network during development results in malformation and malfunction of organs, diseases such as cancer, and often lethality. 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.
We are elucidating the function of protein-coding and non-coding RNAs using a series of in vitro, ex vivo and and in vivo studies, integrating cell biology, developmental biology, biochemistry, mouse genetics and proteomics. The main research areas include: the interplay of sex differentiation and metabolism, post-tranlsational modifications driving cell fate decision during embryonic gonad differentiation, the role of ncRNAs in testicular and ovarian differentiation, and molecular and cellular analysis of mouse ovary development.
