    Principal Investigator:
    Peter Espenshade, Ph.D.
    Cell Biology

    The Espenshade Lab uses a multi-organismal and multidisciplinary approach to understand how euk...aryotic 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. view more

    Takanari Inoue, Ph.D.
    Cell Biology

    Complexity in signaling networks is often derived from co-opting one set of molecules for multi...ple operations. Understanding how cells achieve such sophisticated processing using a finite set of molecules within a confined space--what we call the "signaling paradox"--is critical to biology and engineering as well as the emerging field of synthetic biology.

    In the Inoue Lab, we have recently developed a series of chemical-molecular tools that allow for inducible, quick-onset and specific perturbation of various signaling molecules. Using this novel technique in conjunction with fluorescence imaging, microfabricated devices, quantitative analysis and computational modeling, we are dissecting intricate signaling networks.

    In particular, we investigate positive-feedback mechanisms underlying the initiation of neutrophil chemotaxis (known as symmetry breaking), as well as spatio-temporally compartmentalized signaling of Ras and membrane lipids such as phosphoinositides. In parallel, we also try to understand how cell morphology affects biochemical pathways inside cells. Ultimately, we will generate completely orthogonal machinery in cells to achieve existing, as well as novel, cellular functions. Our synthetic, multidisciplinary approach will elucidate the signaling paradox created by nature.

  • Steven Claypool Lab

    Principal Investigator:
    Steven Claypool, Ph.D.
    Physiology

    Research in the Claypool Lab is focused on defining how lipids and membrane proteins interact t...o establish and maintain normal mitochondrial function and how derangements in this complex relationship result in pathophysiology. We have demonstrated that yeast lacking tafazzin recapitulates all of the phospholipid abnormalities observed in human patients and many of the mitochondrial defects.

    Another major project in our lab focuses on the mitochondrial ADP/ATP carrier that is required for oxidative phosphorylation. Researchers are studying how these novel interactions help establish normal mitochondrial function, the biochemical details of these associations, and whether disturbances in these assemblies can contribute to mitochondrial dysfunction.
