Potential Rotation Projects 1. Dopamine Transporter (DAT) Trafficking in Cocaine Addiction DAT is a membrane protein in dopamine (DA) axon teminals whose primary function is to remove released dopamine and thereby terminate synpatic transmission. Addictive psychostimulants, such as cocaine, block DAT function, which increases extracellular DA and is responsible for cocaine's addictive properties. DAT is not static at the plasma membrane, but is dynamically regulated by membrane traffficking. This project is to determine whether DAT membrane trafficking is required for cocaine addiction. Our lab has developed a novel, AAV-mediated, in vivo molecular replacement strategy, that replaces wildytpe DAT with DAT trafficking dysregulated mutants in adult mice. There are 2 possible rotation projects: Project 1a: Rotation students will assist in behaviorally assessing replacement mice as compared to controls, and will additionally use immumohistochemical approaches to validate mutant protein expression in dopamine neurons in situ. Students will gain experience in mouse behavior, brain dissection, preparation of brain slices, and immunhistochemical techniques in mouse brain. Project 1b: Rotation students will develop a CRISPR/Cas9 guide RNA in order to perform gene editing and mutate DAT in vivo, and will test its efficacy in vitro. Students will learn guide RNA design, and mammalian tissue culture, and genomic sequencing. Cocaine's Synaptic Actions at the Dopamine Transporter. Synaptic models. (A) Dopamine released into the extracellular space is rapidly cleared by the dopamine transporter (purple), thereby limiting the postsynaptic dopamine signal. (B) Cocaine binds to and blocks the dopamine transporter, allowing dopamine to accumulate extracellularly and enhancing the postsynaptic signal.
2. Modulatory glutamate signaling: impact on motor function, novelty, and cocaine addiction Glutamate is the major excitatory neurotransmitter in the brain, but also has a modulatory role by signaling through metabotropic glutamate receptors (mGluRs). Recent work from our laboratory revealed that mGluR5 expression in DA neurons is required for DA signaling and several DA-dependent behaviors including motor learning and cocaine reward. However, the circuit- and mechanistic-specific underpinnings of these processes are unkonwn. Using a novel conditional knockout model, we are leveraging genetically encoded DA sensors to determine how DAergic mGluR5 impacts DA neuron function and DA-dependent behaviors in mice. Rotation students will learn to behaviorally assess cocaine addiction in this mouse model, and will learn immunohistochemical approaches to validate viral expression Cocaine Fails to increase DA in mGluR5-DA-silenced mice. Fiber photometry using genetically-encoded DA sensors during cocaine response. Control or mGluR5-DA-silenced mice were injected with 7.5 mg/kg cocaine and DA signals were recorded in the nucleus accumbens using dLight 1.2 sensor. Control mice: Cocaine caused a significant increase in the total DA signal from 3-5 min post-injection as compared to saline-injections. mGluR5-DA-silenced mice: Cocaine failed to significantly increase DA signals. *p<0.05, paired Student's t test, n=4-5.
3. Nociceptin: A neuropeptide that impacts cocaine sensitivity Nociceptin is an endogenous opiate-like neuropeptide that is implicated in pain and reward motivation. Recent studies suggest that nociceptin has the capacity to block cocaine's initial addictive properties, but the mechanisms underlying nociceptin's actions are largely unknown. Work in our lab has discovered that nociceptin blocks cocaine reward, and does so by acting directly on DA axon terminals in the nucleus accumbens, the brain's "reward center". In addition, our results suggest that nociceptin likely shifts cocaine sensitivity, and does so by controlling reward tone differentially in males vs. females. These exciting results may pave the way towards harnesing nociceptin signaling as a potential addiction therapeutic. However, the mechanisms underlying nociceptin's actions are unknown, nor is it known whether nociceptin specificallly impacts cocaine reward, or other drugs of abuse. There are two possible rotation projects: Project 3a: Impact of nociceptin signaling on other drugs of abuse. Students will conduct addiction behavioral assays while infusing nociceptin directly into the nucleus accumbens in mice. Students will learn mouse handling and stereotaxic surgery, and mouse behavioral assays. Project 3b: Sex-specific differences in nociceptin signalig. Students will use RT-qPCR to test whether males and female mouse midbrain neurons express differing amounts of the nociceptin receptor, NOPR. Students will learn mouse handling skills, brain harvesting, and RT-qPCR. Nociceptin infusion into the nucleus accumbens blocks cocaine preference in females. Conditioned Place Preference Assay (CPP). Wildtype female mice received either saline or 10mg/kg cocaine (I.P.) and were trained for 3 days in a 3-chambered CPP aparatus, while being infused with either vehicle or 500nM nociceptin. Preference scores were determined on test days. Control-infused mice exhibited signifiant preference to the cocaine-paired chamber as compared to the saline-paired chamber (****p<0.001), whereas mice infused with nociceptin failed to establish cocaine preference (p=0.74). Two-way ANOVA with Tukey's multiple comparison test, n=4-10.

Rotation Projects Proper control of cell division and accurate chromosome segregation are fundamental to cell function and normal development. Chromosome segregation errors lead to birth defects, and abnormal cell division control is associated with essentially all cancers. A major aim of research in the laboratory is to understand cell cycle control and chromosome segregation mechanisms. We use a combination of classical and molecular genetics, high-resolution in vivo imaging, and biochemical techniques to define pathways that control the cell cycle and chromosome segregation in response to environmental insult (DNA damaging agents) and developmental queues. Rotation projects focus on the role of cell cycle checkpoint and tumor suppressor pathways during the earliest stages of embryogenesis, and cell cycle control of actin and microtubule reorganization during mitosis. Through these projects, students gain exposure of the art in vivo imaging and genetic and molecular manipulations of gene function to define pathways controlling cell division and chromosome segregation. Embryonic Patterning Essentially all cells are asymmetric, with structurally distinct surfaces and polarized internal organization. This asymmetry is essential to the specialized functions cells serve within complex multi-cellular organisms . A second area of interest focuses on the mechanisms that establish cellular asymmetry. In Drosophila, the embryonic axes are specified during oogenesis through the asymmetric localization of key morphogenetic molecules within the developing oocyte. We use axis specification in the fly as a model for the processes that establish cellular asymmetry. An intact microtubule network is essential to axis specification in the fly oocyte and to polarization of somatic. We hope to define the molecular functions for microtubules in establishing cellular asymmetry. We are currently using in vivo imaging techniques to directly characterize the microtubule dependent mRNA transport processes that differentiate the anterior and posterior poles of the developing oocyte. In addition, classical genetic and biochemical techniques are used to identify the microtubule motors and associated proteins that mediate mRNA movements to the oocyte poles.
One rotation student is expected in the lab to characterize the expression and function of Drosophila gustatory receptor 28b (Gr28b) in phototransduction and taste sensation.

RNAI MEDICINAL CHEMISTRY/ RNA OLIGONUCLEOTIDE CHEMISTRY Develop and characterize novel RNA chemistries to promote efficient oligonucleotide internalization and tissue distribution. Oligonucleotides represent a new class of drugs, which have the promise to become a major class of future therapeutics. There are several chemistries and formulations developed by us and others that effectively support oligo internalization and favorable PK/PD.

SMALL RNA TRAFFICKING Discover, characterize and adapt mechanisms of small RNA extracellular and intracellular trafficking for development of novel classes of oligonucleotide drugs. A serious limitation in realizing the potential of oligonucleotide based therapies has been the exceedingly inefficient transit of oligonucleotides from outside cells to the intracellular compartments where the biologically relevant activity happens. On the other hand, there are multiple lines of evidence supporting the notion that nature has implemented evolutionarily conserved mechanisms and pathways for efficiently trafficking small RNAs across cellular boundaries. The objective of future studies will be the systematic evaluation of mechanisms of cellular uptake of different classes of oligonucleotides and their comparison to mechanisms of native RNA trafficking using a combination of experimental approaches, including advanced RNA chemistry and high temporal and spatial resolution microscopy in living cells, Mass spectrometry, cell biology and others. The successful candidate will work closely with Victor Ambros and Silvia Corvera labs and the UMASS imaging group and receive training in RNA chemistry, biochemistry, cell biology and pre-clinical development.

Rotation Projects 1) Molecular and neuronal characterization of C. elegans escape behavior Defining sensorimotor circuits requires detailed knowledge of the neural connectivity of the nervous system, and the ability to manipulate the functions of the component neurons and to define and quantify the behavioral outputs. The simplicity and completely defined synaptic connectivity of C. elegans nervous system provides unique opportunity to dissect how neural networks control behavior. 2) Identify genes involved in the processing, expression and subunit composition of voltage-gated calcium channels The release of neurotransmitter from synaptic vesicles is critical for the propagation of signals that generate behavioral outputs. Voltage-gated calcium channels provide the calcium influx essential for synaptic vesicle exocytosis. We are characterizing mutants to identify new genes involved in the proper assembly, expression and trafficking of functional calcium channels. 3) Investigate the evolutionary origins of escape behavior Nematophagous fungi employ a variety of strategies to capture worms. In predator-prey experiments, we have been able to show that the suppression of head movements allows the animal to escape from constricting traps. Further investigation of the neurobiology behind the escape from predation may provide insight into how this behavior evolves.
