Faculty in the Department of Biology at Drexel University
Research Interests: Understanding the mechanisms that govern epigenetic regulation of higher order brain function. Epigenetic-based mechanisms underlying neurodegenerative disorders, and broad insights into HAT (histone acetyltransferase)-based drug design for early therapeutic intervention of cognitive deficits.
Research Interests: My laboratory focuses its research efforts on identifying and characterizing genes that are involved in pathogenesis of Alzheimer’s disease (AD). We believe our efforts will lead to the identification of novel therapeutic strategies to delay or prevent onset of AD.
Research Interests: Regulation of cell metabolism and its relevance in major human diseases such as cancer, cardiovascular disorders and diabetes.
Research Interests: Understanding the molecular mechanisms that underlie the morphogenesis of epithelial and neuronal tissues; focus on regulation of the cytoskeleton and its functions by a novel family of GTP-binding proteins termed septins.
Adjunct Faculty at Fox Chase Cancer Center
Research Interests: Personalized medicine initiatives to impact early diagnosis and cancer treatment; identifying novel genetic risk factors that can be relevant to cancer risk assessment, biomarker development and potential optimization of personalized treatment; investigating the molecular circuits that govern DNA damage response and how changes in these can contribute to cancer.
Research Interests: Understanding how viruses interact with cells, trigger cell death, provoke innate immune responses, and induce disease; leveraging these discoveries to develop new therapies for virus infections and human cancers; identifying signaling nodes in antiviral innate immune pathways through CRISPR and other screening approaches.
Research Interests: Genetic and epigenetic alterations of cancer cells in an effort to understand normal gene function and pathogenesis of disease, with the ultimate goal of identifying critical regulatory molecules/pathways as targets for innovative approaches of cancer prevention and therapy.
Research Interests: Signal transduction by small G proteins and their effectors and the role of these proteins in regulating cytoskeletal structure, tumor invasion, and metastasis; regulation of insulin signaling.
Research Interests: Isolating primary fibroblasts from various murine and human cancers at different stages of tumorigenesis.
Research Interests: Computational structural biology, including homology modeling, fold recognition, molecular dynamics simulations, statistical analysis of the PDB and bioinformatics.
Research Interests: Research in my group focuses on the tissue and cellular dynamics during aging, chronic tissue damage and continuous regeneration leading to the development of cancer.
Research Interests: Understanding points of communication between the cell cycle machinery and cell shape controls, with particular reference to how these processes are simultaneously disrupted in cancer; the HEF1, HEI10, and HEI-C proteins, which function in cell cycle-cell attachment control pathways.
Research Interests: Protein quaternary structure dynamics; the morpheein model of allosteric regulation; quaternary structure as a basis for understanding disease and discovering drugs.
Research Interests: The Johnson laboratory studies mechanisms of DNA damage detection, repair, and signaling that occur in BRCA1 mutation-containing organisms and cancers. We use a range of approaches, including cell biology, mouse genetics, and therapy resistance modeling, to understand basic biological processes and their implications for tumorigenesis and chemotherapy sensitivity.
Research Interests: The goal of the Karanicolas laboratory is to develop structure-based approaches for modulating protein function using small-molecules. We apply these new approaches to re-activate disabled tumor suppressors, inhibit cancer-driving RNA-binding proteins, disable key oncogenic kinases, and tune the activity of antibodies used in cancer immunotherapy.
Research Interests: Uncovering immune-mediated mechanisms regulating cardiovascular disease (CVD) development, adipose tissue inflammation and cancer with particular emphasis on the role of cytokines in the regulation of intestinal microbiota, metabolites, stress hematopoiesis in the bone marrow, and anti-cancer immunity.
Research Interests: Molecular chaperone correction of missense mutations; genetic defects of methionine metabolic enzymes and human disease.
Research Interests: Our goal is to understand the mechanisms that control epithelial stem cell function in vivo. Since identifying novel signals that regulate stem cell function is technically challenging in mammalian tissues, we are focusing on Drosophila ovarian follicular epithelium stem cells (FSCs) as a model system for this analysis.
Research Interests: Understanding how the Rho family of signaling proteins function in normal cells and how their signaling is altered in cancer and metastasis.
Research Interests: Immune regulatory pathways in human lymphoid malignancies. We are interested in the immune signaling pathways, particularly key transcriptional factors and ubiquitin-mediated signaling, required for lymphoma pathogenesis and immunotherapy. We have established an unbiased high-throughput CRISPR library screening technology to rapidly and accurately identify key pathways that are suitable for targeted therapy and immunotherapy.
Research Interests: The mechanisms that regulate genome stability and how these processes are disrupted in cancer cells; mechanisms in cancer cells that promote their survival in response to chemotherapy using hi-throughput siRNA and small molecule screens; development of assays including imaging and biochemical assays.
Adjunct Faculty at Lankenau Institute for Medical Research
Research Interests: Understanding molecular and genetic interactions that exist between tumors and the host environment as the basis for developing novel approaches for achieving effective therapeutic intervention.
