A postdoc position is available to study circadian rhythms in Drosophila. Contact Patrick Emery (patrick.emery@umassmed.edu).
Biological clocks play an essential role in the temporal organization of animal physiology and behavior. We combine the powerful genetics of Drosophila with molecular, cell culture and behavioral approaches to obtain a comprehensive view of the mechanisms regulating circadian clocks and one of their critical output: sleep. We also now study the mechanisms enabling marine organisms to anticipate tides. Indeed, we have developed a model organism to study circatidal rhythms: Parhyale hawaiensis. Rotation projects could for example focus on characterizing new candudate post-transcriptional regulators of circadian rhythms, the role of glial genes in the control of sleep, or studying the molecular mechanisms of circatidal clocks.

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.

There are also new chemistries being developed to further improve oligonucleotide tissue distribution and cellular uptake. The successful candidate will be a key part of an intra-disciplinary team working with biologists and chemists to develop novel types of therapeutics for treatment of neurological disease, liver disease and orphan indications. The work will include compounds identification, screening, characterization, in vivo efficacy and PK/PD studies, novel assays development etc. In addition exposure and training in nucleic acid pre-clinical development, project management etc will be provided. QUALIFICATIONS: Applicants must have (or expect to obtain shortly) a Ph.D. in Chemistry, Organic Chemistry Biochemistry, Cell Biology, Molecular Biology or a related field , be bright, ambitious, independent and collaborative and ideally, have research experience in nucleic acid molecular cell biology or pharmacology.
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. In most cases in vivo efficacy is limited by (1) poor PK (2) inefficient tissue distribution (3) compound entrapment in biologically inactive intracellular compartments. The objective of future studies will be development of novel chemistries, which promote receptor mediated cellular internalization and/ or endosomal escape. The successful candidate will be responsible for the design and synthesis of novel RNA precursors, optimization of RNA synthesis and conjugation protocols and interface with the biology part of the lab. In addition, exposure to pre-clinical development programs and oligonucleotide manufacturing will be available.

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.
