Our research focuses on understanding mechanisms of cardiovascular and metabolic health effects of inhaled air pollutants. Specific emphasis is given to susceptibility variations due to underlying cardiovascular disease, obesity, and diabetes. The roles of genetic versus physiological factors are examined. We use molecular and high throughput genomics, and proteomics techniques to establish a link with disease phenotype and physiological alterations. State-of-the-art EPA inhalation facilities are used for air pollution exposures in animal models with or without genetic predisposition. The role of environment in disease burden is the focus. |

The Laederach Lab is interested in better understanding the relationship between RNA structure and folding and human disease. We use a combination of computational and experimental approaches to study the process of RNA folding and in the cells. In particular, we develop novel approaches to analyze and interpret chemical and enzymatic mapping data on a genomic scale. We aim to fundamentally understand the role of RNA structure in controlling post-transcriptional regulatory mechanisms, and to interpret structure as a secondary layer of information (http://www.nature.com/nature/journal/v505/n7485/full/505621a.html). We are particularly interested in how human genetic variation affects RNA regulatory structure. We investigate the relationship between disease-associated Single Nucleotide Polymorphisms occurring in Human UTRs and their effect on RNA structure to determine if they form a RiboSNitch. |

My research goals are to identify the mechanisms by which environmental factors regulate smooth muscle cell phenotype and to define the transcriptional pathways that regulate SMC-specific gene expression. |

The primary focus of my research is to understand the genetic mechanisms underlying stem cell maintenance and differentiation with the goal of translating this information into therapeutic strategies. Using a Sox9EGFP mouse model and FACSorting we are able to specifically enrich for single multipotent intestinal epithelial stem cells that are able to generate mini-guts in a culture system. Our studies are now focused on manipulating, in vitro, the genetics of stem cell behavior through viral gene therapeutics and pharmacologic agents. Additionally, we are developing stem cell transplantation and tissue engineering strategies as therapies for inborn genetic disorders as well as damage and disease of the intestine. Using novel animal models and tissue microarrays from human colon cancers, we are investigating the role of Sox-factors in colorectal cancer. |

The overall goal of our laboratory is to obtain new insights into the host-virus interaction, particularly in HIV infection, and translate discoveries in molecular biology and virology to the clinic to aid in the treatment of HIV infection. A subpopulation of HIV-infected lymphocytes is able to avoid viral or immune cytolysis and return to the resting state. Current work focuses on the molecular mechanisms that control the latent reservoir of HIV infection within resting T cells. We have found that cellular transcription factors widely distributed in lymphocytes can remodel chromatin and maintain quiescence of the HIV genome in resting CD4+ lymphocytes. These studies give insight into the basic molecular mechanisms of eukaryotic gene expression, as well as new therapeutic approaches for HIV infection. |

We are interested in the mechanisms by which histone protein synthesis is coupled to DNA replication, both in mammalian cell cycle and during early embryogenesis in Drosophila, Xenopus and sea urchins. |

PHD PROGRAM RESEARCH INTEREST |
Our lab focuses on the life cycle of cancer-associated human papillomaviruses (HPV); small DNA viruses that exhibit a strict tropism for the epithelium. Several studies in our lab focus on the interface of HPV with cellular DNA damage response (DDR) pathways and how HPV manipulates DNA repair pathways to facilitate viral replication. We are also interested in understanding how the viral life cycle is epigenetically regulated by the DDR as well as by other chromatin modifiers. Additionally, we are investigating how HPV regulates the innate immune response throughout the viral life cycle. |

How does a virus gain control over the host cell? My laboratory is interested in answering this question at the molecular level. By combining molecular biology and virology with new technologies (e.g. mass spectrometry, next generation sequencing), we investigate the mechanisms utilized by viruses to hijack infected cells. By understanding the specific function(s) of viral proteins during infection, we identify strategies used by viruses for deregulation of host cell processes. We use this information to characterize novel features of cell signaling pathways during infection, and to identify potential targets for anti-viral therapeutics. |

PHD PROGRAM RESEARCH INTEREST |
Our lab seeks to better understand the maturation and regulation of a group of human lipases. We aim to uncover how these lipases properly fold and exit the ER, and how their activity is subsequently regulated. We study the membrane-bound and secreted proteins that play a role in lipase regulation. Our research can potentially impact human health as biochemical deficiencies in lipase activity can cause hypertriglyceridemia and associated disorders, such as diabetes and atherosclerosis. We are an interdisciplinary lab and aim to address these questions using a variety of techniques, including membrane protein biochemistry, enzymology, and structural and molecular biology. |

PHD PROGRAM RESEARCH INTEREST |
My laboratory has two main interests: 1) Regulation of P2Y receptor signaling and trafficking in epithelial cells and platelets. Our laboratory investigates the cellular and molecular mechanisms by which P2Y receptors are differentially targeted to distinct membrane surfaces of polarized epithelial cells and the regulation of P2Y receptor signaling during ADP-promoted platelet aggregation. 2) Antibiotic resistance mechanisms. We investigate the mechanisms of antibiotic resistance in the pathogenic bacterium, Neisseria gonorrhoeae. Our laboratory investigates how acquisition of mutant alleles of existing genes confers resistance to penicillin and cephalosporins. We also study the biosynthesis of the gonococcal Type IV pilus and its contribution to antibiotic resistance. |
