Kalina Hristova Lab
The Kalina Hristova Lab investigates the structure and assembly of biological membranes. Our team conducts research on the structural and thermodynamic principles that enable membrane protein folding and signal transduction across biological membranes. Part of our work has involved developing new tools to study the structure of thermally disordered fluid membranes and the energetics of biomolecular interactions in biological membranes. Through our studies, we have established a better understanding of the physical principles behind complex biological processes and the mechanisms of disease development in humans. -
Katherine Wilson Lab
Research in the Wilson Lab focuses on three components of nuclear lamina structure: lamins, LEM-domain proteins (emerin), and BAF. These three proteins all bind each other directly, and are collectively required to organize and regulate chromatin, efficiently segregate chromosomes and rebuild nuclear structure after mitosis. Mutations in one or more of these proteins cause a variety of diseases including Emery-Dreifuss muscular dystrophy (EDMD), cardiomyopathy, lipodystrophy and diabetes, and accelerated aging. We are examining emerin's role in mechanotransduction, how emerin and lamin A are regulated, and whether misregulation contributes to disease. -
Karen Reddy Laboratory
The focus of the research in the Reddy Laboratory is to begin to understand how the nuclear periphery and other subcompartments contribute to general nuclear architecture and to specific gene regulation. Our research goals can be broken down into three complementary areas of research: understanding how genes are regulated at the nuclear periphery, deciphering how genes are localized (or ""addressed"") to specific nuclear compartments and how these processes are utilized in development and corrupted in disease. -
Older Americans Independence Center
The Older Americans Independence Center (OAIC) studies frailty, an age-related condition in which older adults lose the capacity to cope with stressors and become vulnerable to functional decline, loss of independence and mortality. Since its original funding in 2003, the center has helped demonstrate that frailty is a syndrome caused by multiple biological mechanisms that are expressed through characteristics of decreased resiliency and reserve in older adults. The mission of OAIC is to provide a hypothesis-driven, frailty-focused, highly interdisciplinary center where supported investigators receive the expertise, resources and training necessary to make fundamental discoveries related to the origins and causes of frailty and then move these discoveries towards frailty-focused interventions. -
Natalie West Lab
The Natalie West Lab collaborates with Noah Lechtzin’s lab to study cystic fibrosis, with a particular focus on new resistant bacteria and their effect on the lung function of people with cystic fibrosis. -
Nicholas Flavahan Lab
The Nicholas Flavahan Lab primarily researches the cellular interactions and subcellular signaling pathways that control normal vascular function and regulate the initiation of vascular disease. We use biochemical and molecular analyses of cellular mediators and cell signaling mechanisms in cultured vascular cells, while also conducting physiological assessments and fluorescent microscopic imaging of signaling systems in isolated blood vessels. A major component of our research involves aterioles, tiny blood vessles that are responsible for controlling the peripheral resistance of the cardiovascular system, which help determine organ blood flow. -
Florin Selaru Lab
Research interests in the Florin Selaru Lab comprise the molecular changes associated with the transition from inflammatory states in the GI tract (colon, stomach, biliary tree) to frank cancers. In addition, our current research—funded by the AGA, FAMRI and the Broad Foundation—works to further the understanding of cancer development and progression in the gastrointestinal tract. -
Follow the Leader: Specialized Cancer Cells Lead Collective Invasion (Ewald Lab)
Research in the Ewald laboratory starts from a simple question: Which cells in a breast tumor are the most dangerous to the patient and most responsible for metastatic disease? To answer this question, we developed novel 3-D culture assays to allow real-time analysis of invasion. Our data reveal that K14+ cancer cells play a central role in metastatic disease and suggest that the development of clinical strategies targeting these cells will provide novel breast cancer treatments. -
Franck Housseau Lab
The Franck Housseau Lab focuses on the role of the microbiome in colorectal tumorigenesis and on developing a better understanding of the tumor immune microenvironment. The lab is currently working to define the biomarkers of a pre-existing antitumor immune response in metastatic colorectal cancer to define a population of patients eligible for checkpoint blockade therapies. -
Frederick Anokye-Danso Lab
The Frederick Anokye-Danso Lab investigates the biological pathways at work in the separation of human pluripotent stem cells into adipocytes and pancreatic beta cells. We focus in particular on determinant factors of obesity and metabolic dysfunction, such as the P72R polymorphism of p53. We also conduct research on the reprogramming of somatic cells into pluripotent stem cells using miRNAs.
