Laminar organization of neurons in cerebral cortex is critical for normal brain function. Two distinct cellular events guarantee the emergence of laminar organization– coordinated sequence of neuronal migration, and generation of radial glial cells that supports neurogenesis and neuronal migration. Our goal is to understand the cellular and molecular mechanisms underlying neuronal migration and layer formation in the mammalian cerebral cortex. Towards this goal, we are studying the following three related questions: 1. What are the signals that regulate the establishment, development and differentiation of radial glial cells, a key substrate for neuronal migration and a source of new neurons in cerebral cortex?2. What are the signals for neuronal migration that determine how neurons reach their appropriate positions in the developing cerebral cortex?3. What are the specific cell-cell adhesion related mechanisms that determine how neurons migrate and coalesce into distinct layers in the developing cerebral cortex? |

Sleep is an essential and evolutionarily conserved process that modifies synapses in the brain to support cognitive functions such as learning and memory. We are interested in understanding the molecular mechanisms of synaptic plasticity with a particular interest in sleep. Using mouse models of human disease as well as primary cultured neurons, we are applying this work to understanding and treating neurodevelopmental disorders including autism and intellectual disability. The lab focuses on biochemistry, pharmacology, animal behavior and genetics. |

Lipids are crucial molecules for life. They play important roles in building membranes, storing energy, and cell signaling. We are interested in how lipids move around both within cells and between cells, for example from astrocytes to neurons. The lab uses cutting-edge microscopy techniques including live-cell imaging, superresolution microscopy, and multispectral imaging. We use these approaches to understand how defects in lipid trafficking contribute to metabolic and neurodegenerative diseases. |

The Jones lab is interested in heterotrimeric G protein-coupled signaling and uses genetic model systems to dissect signaling networks. The G-protein complex serves as the nexus between cell surface receptors and various downstream enzymes that ultimately alter cell behavior. Metazoans have a hopelessly complex repertoire of G-protein complexes and cell surface receptors so we turned to the reference plant, Arabidopsis thaliana, and the yeast, Saccharomyces cerevisiae, as our models because these two organisms have only two potential G protein complexes and few cell surface receptors. Their simplicity and the ability to genetically manipulate genes in these organisms make them powerful tools. We use a variety of cell biology approaches, sophisticated imaging techniques, 3-D protein structure analyses, forward and reverse genetic approaches, and biochemistries. |

Emotional behavior is regulated by a host of chemicals, including neurotransmitters and neuromodulators, acting on specific circuits within the brain. There is strong evidence for the existence of both endogenous stress and anti-stress systems. Chronic exposure to drugs of abuse and stress are hypothesized to modulate the relative balance of activity of these systems within key circuitry in the brain leading to dysregulated emotional behavior. One of the primary focuses of the Kash lab is to understand how chronic drugs of abuse and stress alter neuronal function, focusing on these stress and anti-stress systems in brain circuitry important for anxiety-like behavior. In particular, we are interested in defining alterations in synaptic function, modulation and plasticity using a combination of whole-cell patch-clamp physiology, biochemistry and mouse models. Current projects are focused on the role of a unique population of dopamine neurons in alcoholism and anxiety. |

Our research explores the role of hypoxia-inducible factor (HIF) in tumorigenesis. HIF is a transcription factor that plays a key role in oxygen sensing, the adaptation to hypoxia and the tumor microenvironment. It is expressed in the majority of solid tumors and correlates with poor clinical outcome. Therefore, HIF is a likely promoter of solid tumor growth and angiogenesis. Our lab uses mouse models to ask if and how HIF cooperates with other oncogenic events in cancer. We are currently investigating HIF’s role in the upregulation of circulating tumor cells and circulating endothelial cells. |

We study large multinucleate cells such as fungi, muscle and placenta to understand how cells are organized in time and space. Using quantitative live cell microscopy, biochemical reconstitution and computational approaches we examine how the physical properties of molecules generate spatial patterning of cytosol and scaling of cytoskeleton scaffolds in the cell cycle. |

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. |

Our fundamental interest is in how the nervous system processes sensory information. We have been studying these problems using in vitro preparations that allow us to examine how single cells in the auditory cortex and auditory brainstem operate to integrate synaptic input, generate precisely timed action potentials, and adapt to changes in sensory input produced by hearing loss. This has involved investigations into the kinds of ion channels expressed in particular subsets of cells, determination of the kinetics and voltage dependence of those channels, studies of synaptic transmission, and the generation of computational models that reflect our current understanding of how these cells operate and produce responses to acoustic stimuli. A longstanding interest has been in the types of processing that take place in the elaborate network of cells in cerebral cortex. The structure and function of neurons in the auditory cortex depends extensively on sensory experience. We are now studying the functional spatial organization of auditory cortical neural networks at the level of connections between classes individual cells, using optical methods in normal mice and mice with noise-induced hearing loss. |
