PHD PROGRAM RESEARCH INTEREST |
Our research centers on understanding the molecular basis of human carcinogenesis. In particular, a major focus of our studies is the Ras oncogene and Ras-mediated signal transduction. The goals of our studies include the delineation of the complex components of Ras signaling and the development of anti-Ras inhibitors for cancer treatment. Another major focus of our studies involves our validation of the involvement of Ras-related small GTPases (e.g., Ral, Rho) in cancer. We utilize a broad spectrum of technical approaches that include cell culture and mouse models, C. elegans, protein crystallography, microarray gene expression or proteomics analyses, and clinical trial analyses. |

PHD PROGRAM RESEARCH INTEREST |
The Cyr laboratory studies cellular mechanisms for cystic fibrosis and prion disease. We seek to determine how protein misfolding leads to the lung pathology associated with Cystic Fibrosis and the neurodegeneration associated with prion disease. |

PHD PROGRAM RESEARCH INTEREST |
Our lab is interested in molecular mechanisms of oncogenesis, specifically as regulated by Ras and Rho family small GTPases. We are particularly interested in understanding how membrane targeting sequences of these proteins mediate both their subcellular localization and their interactions with regulators and effectors. Both Ras and Rho proteins are targeted to membranes by characteristic combinations of basic residues and lipids that may include the fatty acid palmitate as well as farnesyl and geranylgeranyl isoprenoids. The latter are targets for anticancer drugs; we are also investigating their unexpectedly complex mechanism of action. Finally, we are also studying how these small GTPases mediate cellular responses to ionizing radiation – how do cells choose whether to arrest, die or proliferate? |
| Cook, Jeanette (Jean) WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Cook lab studies the major transitions in the cell division cycle and how perturbations in cell cycle control affect genome stability. We have particular interest in mechanisms that control protein abundance and localization at transitions into and out of S phase (DNA replication phase) and into an out of quiescence. We use a variety of molecular biology, cell biology, biochemical, and genetic techniques to manipulate and evaluate human cells as they proliferate or exit the cell cycle. We collaborate with colleagues interested in the interface of cell cycle control with developmental biology, signal transduction, DNA damage responses, and oncogenesis. |

PHD PROGRAM RESEARCH INTEREST |
Males and females differ in their prelevance, treatment, and survival to a diverse set of human disease states. This is exemplified cardiovascular disease, a disease that takes more lives than all forms of cancer combined. In cardiac disease, women almost uniformly fare far worse than men: as of 2007 one woman dying for cardiovascular disease in the US every minute. Our lab focuses on sex disparities in development and disease. For these studies, we use a highly integrated approach that incorporates developmental, genetic, proteomic, biochemical and molecular-based studies in mouse and stem cells. Recent advances by our past students (presently at Harvard, John Hopkins and NIH) include studies that define the cellular and molecular events that lead to cardiac septation, those that explore cardiac interaction networks as determinants of transcriptional specificity, the mechanism and function of cardiac transcriptional repression networks, and the regulatory networks of cardiac sexual dimorphism. Our lab has opening for rotation and PhDs to study these rapidly emerging topics. |
| Cheney, Richard WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
Our goal is to understand the fundamental cell biology underlying processes such as neurodevelopment, angiogenesis, and the metastasis of cancer cells. Most of our experiments focus on molecular motors such as myosin-X and on the finger-like structures known as filopodia. We generally utilize advanced imaging techniques such as TIRF and single-molecule imaging in conjunction with mammalian cell culture. We also use molecular biology and biochemistry and are in the process of developing a mouse model to investigate the functions of myosin-X and filopodia. We are looking for experimentally driven students who have strong interests in understanding the molecular basis of dynamic cellular processes such as filopodial extension, mechanosensing, and cell migration. |

PHD PROGRAM RESEARCH INTEREST |
Gene targeting and state-of-the-art phenotyping methods are used to elucidate the reproductive and cardiovascular roles of the adrenomedullin system and to characterize the novel GPCR-signaling mechanism of Adm’s receptor and RAMP’s. |
| Campbell, Sharon WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
Current research projects in the Campbell laboratory include structural, biophysical and biochemical studies of wild type and variant Ras and Rho family GTPase proteins, as well as the identification, characterization and structural elucidation of factors that act on these GTPases. Ras and Rho proteins are members of a large superfamily of related guanine nucleotide binding proteins. They are key regulators of signal transduction pathways that control cell growth. Rho GTPases regulate signaling pathways that also modulate cell morphology and actin cytoskeletal organization. Mutated Ras proteins are found in 30% of human cancers and promote uncontrolled cell growth, invasion, and metastasis. Another focus of the lab is in biochemical and biophysical characterization of the cell adhesion proteins, focal adhesion kinase, vinculin, paxillin and palladin. These proteins are involved in actin cytoskeletal rearrangements and cell motility, amongst other functions. Most of our studies are conducted in collaboration with laboratories that focus on molecular and cellular biological aspects of these problems. This allows us to direct cell-based signaling, motility and transformation analyses. Member of the Molecular & Cellular Biophysics Training Program. |

PHD PROGRAM RESEARCH INTEREST |
We are interested in the mechanism by which eukaryotic cells are polarized and the role of vesicle transport plays in the determination and regulation of cell polarity and tumorigenesis. |
| Brenman, Jay WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Brenman lab studies how a universal energy and stress sensor, AMP-activated protein kinase (AMPK) regulates cellular function and signaling. AMPK is proposed to be a therapeutic target for Type 2 diabetes and Metabolic syndrome (obesity, insulin resistance, cardiovascular disease). In addition, AMPK can be activated by LKB1, a known human tumor suppressor. Thus AMPK signaling is not only relevant to diabetes but also cancer. We are interested in molecular genetic and biochemical approaches to understand how AMPK contributes to neurodegeneration, metabolism/cardiac disease and cancer. |
