Wnt Enhancer LandscapE CharacTerization
Cancer remains one of the major health challenges in Europe. In recent years, a lot of clinical efforts have focused on targeting developmental signalling pathways for cancer therapy. One of the signalling cascades that has emerged as key regulator of both adult stem cells and cancer (stem) cells is the Wnt pathway. In human breast tumours, deregulation of different Wnt signalling components is frequently observed, ranging from overexpression of individual Wnt genes to elevated levels of the downstream effector beta-catenin. However, in the absence of apparent dominant genetic mutations, the mechanism behind those alterations is unclear. In fact, very little is known about the precise spatio-temporal regulation of Wnt ligands during tissue homeostasis and disease to begin with. The long-term goal of our research is to uncover how environmental and intrinsic signals are integrated to control dynamic Wnt expression patterns during both normal development and tumour formation. In this project, we aimed to combine bioinformatics, state-of-the-art genome engineering and an innovative screening approach to identify Wnt-associated enhancers in the mammary gland.

Project objective
Despite significant efforts, cancer remains one of the major health challenges in Europe.In essence, cancer can be seen as the result of alterations in the intricate balance between cell proliferation, differentiation and death during tissue homeostasis. Hence, pathways that are essential for the development and maintenance of mammalian tissues are frequently deregulated in human tumors and represent attractive targets for therapeutic intervention.In that respect, the Wnt signal transduction pathway serves as a paradigm: On the one hand, Wnt ligands are crucial determinants of cell fate decisions and can act as self-renewal factors for adult stem cells in multiple tissues, including the mammary gland. On the other hand, aberrant activation of the Wnt/beta-catenin pathway is a hallmark of many human (breast) tumors.While it is clear that Wnt activity has to be carefully coordinated in precise temporal and tissue-specific patterns, there is a significant knowledge gap regarding the underlying control mechanisms.In this project, I will combine bioinformatics, state-of-the-art genome engineering and an innovative screening approach to identify Wnt-associated enhancers in the mammary gland.I aim to:1. Establish an effective experimental pipeline for an epigenetic screen.2. Identify functional regulatory sequences for almost half of the mammalian Wnt genes.3. Validate individual enhancers in vivo.The proposed research together with the training I will receive in an excellent, multidisciplinary research environment will significantly benefit my scientific career development.Finally, I envisage that my results will provide the basis for uncovering how environmental and intrinsic signals are integrated to control dynamic Wnt expression patterns in both normal development and cancer.
