The Devreotes Laboratory is engaged in genetic analysis of chemotaxis in eukaryotic cells. Our long-term goal is a complete description of the network controlling chemotactic behavior. We are analyzing combinations of deficiencies to understand interactions among network components and carrying out additional genetic screens to identify new pathways involved in chemotaxis. A comprehensive understanding of this fascinating process should lead to control of pathological conditions such as inflammation and cancer metastasis.
The Espenshade Lab uses a multi-organismal and multidisciplinary approach to understand how eukaryotic cells measure insoluble lipids and dissolved gases. We have chosen cholesterol and oxygen as our model molecules, based on their essential roles in cell function and the importance of their proper homeostasis for human health.
The Jun O. Liu Laboratory tests small molecules to see if they react in our bodies to find potential drugs to treat disease. We employ high-throughput screening to identify modulators of various cellular processes and pathways that have been implicated in human diseases from cancer to autoimmune diseases. Once biologically active inhibitors are identified, they will serve both as probes of the biological processes of interest and as leads for the development of new drugs for treating human diseases.
Among the biological processes of interest are cancer cell growth and apoptosis, angiogenesis, calcium-dependent signaling pathways, eukaryotic transcription and translation.
The Taverna Laboratory studies histone marks, such as lysine methylation and acetylation, and how they contribute to an epigenetic/histone code that dictates chromatin-templated functions like transcriptional activation and gene silencing. Our lab uses biochemistry and cell biology in a variety of model organisms to explore connections between gene regulation and proteins that write and read histone marks, many of which have clear links to human diseases like leukemia and other cancers. We also investigate links between small RNAs and histone marks involved in gene silencing.
