Úloha transkripčního faktoru Msx1 ve střevním epitelu a nádorech / The role of the Msx1 transcription factor in the intestinal epithelia and colorectal cancer

The Wnt signaling pathway represents the principal evolutionarily conserved signaling cascade found in all multicellular organisms. It plays a key role not only in many processes during embryogenesis, but also in maintaining tissue homeostasis and regeneration. By contrast, mutations in genes encoding components of the pathway often result in increased activation of Wnt signaling and underlie onset of many human diseases, particularly cancer. The canonical Wnt signaling pathway is essential for proliferation and maintenance of the pluripotent state of intestinal stem cells and thus for homeostatic renewal of the intestinal epithelium. However, aberrant (hyper)activation of the Wnt signaling pathway is the initial step in development of intestinal neoplasia. Understanding the causes and identifying the consequences of the Wnt signaling hyperactivation is crucial for deciphering mechanisms leading to malignant transformation. Although the canonical Wnt signaling pathway has been the subject of scientific studies for several decades, all regulatory mechanisms and consequences of its hyperactivation have not been completely elucidated yet. During my PhD studies, I focused on understanding function(s) of some components and target genes of this signaling cascade. In this theses, results of my first...
