Dr. Shih is the Director of Small Animal Magnetic Resonance Imaging (MRI) at the Biomedical Research Imaging Center. His lab has implemented multi-model MRI techniques at high magnetic field to measure cerebral blood oxygenation, blood flow, blood volume, and oxygen metabolism changes in preclinical animal models. Dr. Shih’s lab is also developing simultaneous functional MRI (fMRI) and electrophysiology recording techniques at high spatial resolution to elucidate the pathophysiological mechanisms of neurovascular diseases. They will apply these techniques to (i) explore/validate functional connectivity network and neurovascular coupling in the rodent brain, (ii) study tissue characteristics after stroke, and (iii) investigate deep brain electrical stimulation, optogenetic stimulation, and pharmacogenetic stimulation in normal and Parkinsonian animal models.

Our lab examines cytoskeletal dynamics, the molecules that regulate it and the biological processes it is involved in using live cell imaging, in vitro reconstitution and x-ray crystallography.  Of particular interest are the microtubule +TIP proteins that dynamically localize to microtubule plus ends, communicate with the actin network, regulate microtubule dynamics, capture kinetochores and engage the cell cortex under polarity-based cues.

Local mRNA translation is critical for axon regeneration, synapse formation, and synaptic plasticity. While much of research has focused on local translation in dendrites and in peripheral axons, less is known about local translation in smaller diameter central axons due to the technical difficulty of accessing them. We developed microfluidic technology to allow access to axons, as well as nascent boutons and fully functional boutons. We identified multiple transcripts that are targeted to cortical and hippocampal axons in rat (Taylor et al. J Neurosci 2009). Importantly, this work countered the prevailing view that local mRNA translation does not occur in mature axons. We are actively investigating transcripts in axons that may play a role in establishing proper synaptic connections. We are also using our technology to identify transcripts targeted to axons and boutons in human neurons. These studies are a critical step towards the identification of key genes and signaling molecules during synapse development, axonal regeneration, and proper circuit function.

My primary research interests are directed at the neurobiology of alcoholism. To study the central mechanisms involved with neurobiological responses to ethanol, I use both genetic and pharmacological manipulations. There are many factors that may cause an individual to progress from a moderate or social drinker to an alcoholic. In addition to environmental influences, there is growing evidence in both the human and animal literature that genetic factors contribute to alcohol abuse. Furthermore, the risk for developing alcoholism is likely not associated with a single gene, but rather with multiple genes that interact with environmental factors to determine susceptibility for uncontrolled drinking. Some of the questions that my laboratory is currently addressing are: 1) Does central neuropeptide Y (NPY) signaling modulate neurobiological responses to ethanol and ethanol consumption, 2) Do melanocortin peptides modulate ethanol intake? and 3) Does cAMP-dependent kinase (PKA) play a role in voluntary ethanol consumption and/or other effects produced by ethanol?

The vertebrate retina is an extension of the central nervous system that controls visual signaling and circadian rhythm.  Our laboratory is interested in how the retina adapts to changing light intensities in the natural environment.  We are presently studying the regulation of 2 G protein-coupled receptor kinases, GRK1 and GRK7, that participate in signal termination in the light-detecting cells of the retina, the rods and cones.  Signal termination helps these cells recover from light exposure and adapt to continually changing light intensities.  Recently, we determined that GRK1 and GRK7 are phosphorylated by cAMP-dependent protein kinase (PKA).  Since cAMP levels are regulated by light in the retina, phosphorylation by PKA may be important in recovery and adaptation.  Biochemical and molecular approaches are used in 2 model organisms, mouse and zebrafish, to address the role of PKA in retina function. Keywords:  cAMP, cone, G protein-coupled receptor, GPCR, GRK, kinase, neurobiology, opsin, PKA, retina, rhodopsin rod, second messenger, signal transduction, vision.

Our research is focused on two general areas:  1. Autism and 2. Pain.  Our autism research is focused on topoisomerases and other transcriptional regulators that were recently linked to autism.  We use genome-wide approaches to better understand how these transcriptional regulators affect gene expression in developing and adult neurons (such as RNA-seq, ChIP-seq, Crispr/Cas9 for knocking out genes).  We also assess how synaptic function is affected, using calcium imaging and electrophysiology.   In addition, we are performing a large RNA-seq screen to identify chemicals and drugs that increase risk for autism.   /  / Our pain research is focused on lipid kinases that regulate pain signaling and sensitization.  This includes work with cultured dorsal root ganglia (DRG) neurons, molecular biology and behavioral models of chronic pain.  We also are working on drug discovery projects, with an eye towards developing new therapeutics for chronic pain.

My research aims to uncover the molecular aspects of protein aggregation diseases (also called PAD) which include neurodegenerative diseases (such as Alzheimer’s disease and Amyotrophic Lateral Sclerosis), myofibrillar myopathies (such as muscular dystrophies), as well as the formation of age-related cataracts.  Although very distinct, these disorders share a common underlying pathogenic mechanism.  Using a combination of biochemistry and in vitro approaches, cell biology, and primary cells / transgenic mouse models, we will investigate the post-translational modifications (PTMs) that drive these disease processes. Ultimately, this research will provide a platform for future drug discovery efforts against these devastating diseases.

Our primary research interest is to identify the mechanisms that regulate neural circuit organization and function at distinct stages of adult neurogenesis, and to understand how circuit-level information-processing properties are remodeled by the integration of new neurons into existing circuits and how disregulation of this process may contribute to various neurological and mental disorders. Our long-range goals are to translate general principles governing neural network function into directions relevant for understanding neurological and psychiatric diseases. We are addressing these questions using a combination of cutting-edge technologies and approaches, including optogenetics, high-resolution microscopy, in vitro and in vivo electrophysiology, genetic lineage tracing and molecular biology.

The Tarantino lab studies addiction and anxiety-related behaviors in mouse models using forward genetic approaches. We are currently studying a chemically-induced mutation in a splice donor site that results in increased novelty- and cocaine-induced locomotor activity and prolonged stress response. We are using RNA-seq to identify splice variants in the brain that differ between mutant and wildtype animals. We are also using measures of initial sensitivity to cocaine in dozens of inbred mouse strains to understand the genetics, biology and pharmacokinetics of acute cocaine response and how initial sensitivity might be related to addiction. Finally, we have just started a project aimed at studying the effects of perinatal exposure to dietary deficiencies on anxiety, depression and stress behaviors in adult offspring. This study utilizes RNA-seq and a unique breeding design to identify parent of origin effects on behavior and gene expression in response to perinatal diet.

Research in our lab is focused on understanding how cocaine abuse affects glial cell physiology, in particular neuron-astrocyte communication.  We utilize the rat cocaine self-administration/reinstatement model, which allows us to test hypotheses regarding not only how chronic cocaine use affects properties of astrocytes and the tripartite synapse, but also how compounds affecting glial cells may influence synaptic processing within the brain’s reward neurocircuitry and behavioral measures of drug seeking.
