    Research Interest

    Function of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation), in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.

    Dr. Bejerano, co-discoverer of ultraconserved elements, studies the Human Genome. Through computation and experimentation we investigate the Systems Biology parts-list of many thousands genomic regions involved in gene transcription regulation during embryonic development. Major interests include (1) the origins and evolution of these regions, (2) how they encode their individual as well as combined roles, (3) their contribute to human disease, and (4) their contribute to species adaptation.

    Research Interest

    We study the genetics of pancreatic islet cell differentiation using molecular, embryologic and genetic methods in several model systems, including mice, embryonic stem cells, and Drosophila. Our work suggests that critical factors required for islet development are also needed to maintain essential functions of the mature islet. Our knowledge of genetic and cellular pathways governing islet formation has allowed us to use stem cell lines to produce islet replacements in vitro.

    Research Interest

    My laboratory uses a variety of genetic, cellular, and molecular approaches to study skeletal development in humans, mice, and fish. Many of our studies begin with naturally occuring genetic traits that alter skeletal development. By isolating the genes responsible for these traits, it has been possible to identify key pathways that control creation of skeletal tissue, repair of fractures, susceptibility to arthritis, and dramatic modifications of skeletal morphology during vertebrate evolution

    Experimental and theoretical analysis and modeling of genetic regulatory circuits, particularly bacterial regulation and with emphasis on global regulation of Caulobacter crescentus. Bioinformatic analysis of bacterial genomes, of microarray expression patterns, and cross-species genomic analysis. Techniques: gene expression microarrays, fluorescent microscopy, electron microscopy.

    Our laboratory studies Wnt signaling in development and disease. We found recently that Wnt proteins are unusual growth factors, because they are lipid-modified. We also discovered that Wnt proteins promote the proliferation of stem cells of various origins. Current work is directed at understanding the function of the lipid on the Wnt, using Wnt proteins as factors the expand stem cells and on understanding Wnt signaling during injury repair and regeneration.

    Our research focuses on understanding the regulation of genes associated with cardiovascular development and disease, through the use of cultured cells and tissues and genetically modified mouse models. A variety of different aberrant pathways are being characterized, including those related to signaling through the bone morphogenetic proteins, serotonin and the S100 family of calcium binding proteins, and those defining how a microtubule associated protein regulates mRNA translation.

    Genetic regulation of animal development and human disease. We use mice and flies to study Hedgehog/Patched signaling and its links to brain cancer, development of the neural tube and cerebellum, planar cell polarity genes, a neurodegenerative disease called Niemann-Pick syndrome that affects intracellular organelle movements, chromatin proteins in embryonic stem cells, and genetic control of body size.

    A basic question in developmental biology involves the mechanisms used to generate the three-dimensional organization of a cell from a one-dimensional genetic code. Our goal is to define these mechanisms using both molecular genetics and biochemistry.

    The general research interest of this laboratory is the molecular basis of cell motility. We have three specific research interests, the molecular basis of energy transduction that leads to ATP-driven myosin movement on actin, the biochemical basis of the regulation of actin and myosin interaction and their assembly states, and the roles these proteins play in vivo, in cell movement and changes in cell shape.

    Research Interest

    Research in our lab focuses on mechanisms of epigenetic regulation in differentiation and development. In particular, we are studying the function of histone modifying enzymes in embryonic stem cell self-renewal and in early cell fate decisions. We are interested in the role of chromatin modifications in establishment and maintenance of gene expression patterns during normal and pathological development, and in nuclear reprogramming.
