Current Research and Scholarly Interests Telomeres are nucleoprotein complexes that protect chromosome ends and shorten with cell division and aging. We are interested in how telomere shortening influences cancer, stem cell function, aging and human disease. Telomerase is a reverse transcriptase that synthesizes telomere repeats and is expressed in stem cells and in cancer. We have found that telomerase also regulates stem cells and we are pursuing the function of telomerase through diverse genetic and biochemical approaches.
Professor of Genetics
Current Research and Scholarly Interests Our lab studies the molecular basis of longevity. We are interested in the mechanism of action of known longevity genes, including FOXO and SIRT, in the mammalian nervous system. We are particularly interested in the role of these longevity genes in neural stem cells. We are also discovering novel genes and processes involved in aging using two short-lived model systems, the invertebrate C. elegans and an extremely short-lived vertebrate, the African killifish N. furzeri.

Current Research and Scholarly Interests Mechanism of genomic imprinting of insulin like growth factor-2 and other genes.Long range chromatin interactions Role of histone modifications and DNA methylation in gene expression.
Maureen Lyles D'Ambrogio Professor and Professor, by courtesy, of Chemical and Systems Biology
Current Research and Scholarly Interests We study angiogenesis, cancer genomics, intestinal stem cells (ISC), and hepatic glucose metabolism. We use primary organoid cultures of diverse tissues for oncogene functional screening and therapeutics discovery. Angiogenesis projects include endothelial miRNA and GPCR ko mice, blood-brain barrier regulation, stroke therapeutics and anti-angiogenic cancer therapy. ISC projects apply organoid culture and ko mice to injury-inducible vs homeostatic stem cells and symmetric division mechanisms.

Current Research and Scholarly Interests Function and evolution of the Myb oncogene family; function and evolution of E2F transcriptional regulators and RB tumor suppressors; epigenetic regulation of chromatin and chromosomes; cancer genetics.
Mrs. George A. Winzer Professor in Cell Biology
Current Research and Scholarly Interests CELLULAR INFORMATION PROCESSING The main problem in signal transduction is to understand how different receptor-stimuli specifically control diverse cell functions. We are using automated microscopy, live-cell fluorescent biosensors and perturbations of predicted signaling proteins to systematically dissect signaling networks. This allows us to identify signaling modules and to elucidate and ultimately model the flow of cellular information.
Assistant Professor of Molecular and Cellular Physiology
Current Research and Scholarly Interests We study the primary cilium, a once-obscure cellular organelle recently "re-discovered" for its role in a number of signaling pathways. Defects in cilium biogenesis lead to a variety of hereditary disorders characterized by retinal degeneration, kidney cysts and obesity. Our goal is to characterize these disorders at the molecular and cellular levels to gain insight into the basic mechanisms of primary cilium biogenesis and to discover novel ciliary signaling pathways.
Rudy J. and Daphne Donohue Munzer Professor in the School of Medicine and Professor of Molecular and Cellular Physiology
Current Research and Scholarly Interests Our research objectives are to understand the cellular mechanisms involved in the development and maintenance of epithelial cell polarity. Polarized epithelial cells play fundamental roles in the ontogeny and function of a variety of tissues and organs.
Anthony Oro MD/PhD
Professor of Dermatology
Current Research and Scholarly Interests Our lab uses the skin to answer questions about epithelial stem cell biology, differentiation and carcinogenesis using genomics, genetics, and cell biological techniques. We have studied how hedgehog signaling regulates regeneration and skin cancer, and how tumors evolve to develop resistance. We study the mechanisms of early human skin development using human embryonic stem cells. These fundamentals studies provide a greater understanding of epithelial biology and novel disease therapeutics.
Emma Pfeiffer Merner Professor in the Medical Sciences
Current Research and Scholarly Interests The goal of our research is to elucidate the molecular mechanisms by which proteins are targeted to specific membrane compartments. How do transport vesicles select their contents, bud, translocate through the cytoplasm, and then fuse with their targets? We study the Ras-like Rab GTPases--how they serve as master regulators of all receptor trafficking events. We also study how cells acquire cholesterol from the diet and from LDL.
