Main research topics of the Developmental Cellular Physiology and Pathophysiology Lab
Our group is interested in transcriptional mechanisms controlling cardiovascular development and formation of the genitourinary system. The major focus of our work is on the regulation and function of the Wilms’ tumor gene, WT1. Another research topic is the regulation of gene expression by the local oxygen concentration and hypoxia, respectively.

The major focus of our work is on the regulation and function of the Wilms' tumor gene, WT1. Another research topic is the regulation of gene expression by the local oxygen concentration and hypoxia, respectively.
Based on its mutational inactivation in pediatric renal malignancies (Wilms' tumor, nephroblastoma) WT1 has been identified as a tumor suppressor gene. The WT1 gene product belongs to a group of zinc finger proteins that regulate gene transcription by binding to a GC-rich consensus sequence. Some WT1 splice variants exhibit a reduced DNA binding affinity and have been implicated in mRNA processing. Targeted inactivation of Wt1 in mice caused a failure of normal formation of the kidneys and gonads, the mesothelium, hematopoietic tissue and sensory neuroepithelia. Wt1-deficient murine embryos die from a failure of normal heart formation, which is likely due to impaired vascularization of the developing myocardium. Accumulating evidence suggests a role of WT1 in the epithelial-to-mesenchymal transition (EMT) of epicardial progenitor cells, which possess the characteristics of cardiac stem cells. WT1 expression in the heart is increased in hypoxia.
By studying the regulation of WT1 and by identifying WT1 downstream target genes we aim at deciphering key molecular events in cardiovascular and genitourinary differentiation. Our recent findings indicate that WT1 stimulates transcription of the metalloproteinase ADAMTS16 in murine embryonic kidneys and gonads. Transcriptional activation of the Adamts16 gene by WT1 is a critical mechanism for the normal development of these tissues.
Our research is driven by a genuine interest in the transcriptional signaling mechanisms underlying normal embryogenesis. Importantly, the adult organism frequently reactivates an embryonic gene expression program in response to tissue damage. Reexpression of "fetal genes", including WT1, is likely to promote and sustain organ repair. A detailed knowledge of the key molecular pathways in embryonic development can therefore provide important insights in regenerative processes following tissue injury.
