This award is given to Academic Senate or Academic Federation members, who have demonstrated a significant track record of abiding commitment to reducing opportunity gaps for underrepresented students and/or students from underserved communities.
Dr. Gomes has created a wealth of knowledge about best practices for enhancing the undergraduate and graduate training of students from underrepresented, disabled and low socioeconomic status. He also serves as principal investigator for the Initiative for Maximizing Student Development program, which identifies and trains underrepresented graduate students to become part of the next generation of research leaders and innovators in biomedical and behavioral sciences.
The successful application, “A Novel Program to Identify, Support and Retain Clinical Scientists Impacted by Pandemic Caregiving Challenges”, developed by Colleen Clancy, professor and associate vice chancellor for academic personnel and Melissa Bauman, professor and director of UC Davis Health’s Women in Medicine and Health Sciences, who will serve as co-directors, received funding and program support from the Doris Duke Charitable Foundation its funding partner – the Burroughs Wellcome Fund, to bolster research productivity and allow them to participate in small group, professional development mentoring activities. Congratulations!!
In a new study published in PNAS, distinguished professor James Trimmer and his colleagues reveal these protein clusters are calcium signaling “hotspots” in the neuron that play a crucial role in activating gene transcription.
Transcription allows portions of the neuron’s DNA to be “transcribed” into strands of RNA that are then used to create the proteins needed by the cell.
“We developed an approach that let us uncouple the calcium channel from the potassium channel clusters in neurons. A key finding was that this treatment blocked calcium-triggered gene expression. This suggests that the calcium channel-potassium channel partnership at these clusters is important for neuronal function,” Vierra said.
Opioids are powerful painkillers but their use is hindered because patients become tolerant to them, requiring higher and higher doses, and overdoses can cause respiratory depression and death. A recent study from researchers at the UC Davis Center for Neuroscience contradicts existing thinking about how opioid drugs cause tolerance and respiratory depression, and suggests a new, balanced approach to developing safer analgesics. The work was published July 13 in Neuropsychopharmacology.
“The holy grail of opioid research is to determine the ideal properties of an opioid analgesic for maximizing pain relief while reducing the adverse side effects,” said Jennifer Whistler, senior author on the paper and professor of physiology and membrane biology in the UC Davis School of Medicine. “This goal has become even more urgent in light of the devastation wreaked by the opioid overdose crises and the failure to identify other non-opioid targets for the treatment of severe and persistent pain.”
Researchers at UC Davis are developing a new type of pain medication from an unusual source — tarantula venom.
The project is part of the NIH Helping to End Addiction Long-Term (HEAL) Initiative, aimed at ending opioid addiction and creating non-addictive therapies to treat pain.
Vladimir Yarov-Yarovoy, a professor of physiology and membrane biology, and Heike Wulff, a professor of pharmacology, are leading the 20-person team using computational biology to turn a poisonous peptide into one that can relieve pain. Peptides are smaller versions of proteins.
Addgene partnered with James Trimmer, Receives NIH BRAIN Initiative Grant to Create Open-Access Recombinant Antibody Resource
Addgene, the nonprofit plasmid repository, has been awarded a grant from the National Institutes of Health (NIH) to develop a recombinant antibody resource. The grant will be funded by the NIH’s Brain Research through Advancing Innovative Neurotechnologies® (BRAIN) Initiative, a U.S. government wide project aimed at revolutionizing our understanding of the brain and brain disorders. The funding will help Addgene create a much needed open-access recombinant antibody/affinity reagent resource for the neuroscience community called NABOR (Neuroscience AntiBody Open Resource).
For this project, Addgene has partnered with James Trimmer, Ph.D., Distinguished Professor of Physiology and Membrane Biology, University of California Davis School of Medicine. Trimmer, who has created thousands of antibodies/nanobodies for neuroscience research, is an expert at validating these tools. Trimmer will be sharing his tools through this platform and conducting the quality control of the NABOR affinity reagents. While the focus of the NABOR platform will be neuroscience reagents and data, the platform can be expanded for any recombinant antibody tool and therefore will grow to serve the entire scientific community.
Pain often serves as a vital signal of danger and potential tissue damage: Touching a hot stove or breaking a bone requires an immediate reaction to protect us. Such acute pain lasts only until the stimulus is taken away or the underlying injury has healed.
Departmental faculty member, Vladimir Yarov-Yarovoy, Ph.D., and Heike Wulff, Ph.D., of the University of California, Davis lead a 20-person team using computational biology to engineer a tarantula venom into a new treatment for chronic pain. This basic and translational research is part of the Optimizing Non-Addictive Therapies to Treat Pain research program in the Helping to End Addiction Long-termSM Initiative, or NIH HEAL InitiativeSM.
Departmental faculty member, Dr. Theanne Griffith, is the second guest of Chancellor Gary S. May’s new talk show, Face to Face. The episode was released today, and can be watched on YouTube. In the monthly series of video interviews, May said he talks with “students, faculty and staff innovators about what they’re working on and how they’re making a difference in the real world.”
One of UC Davis’ newest faculty members may be focused on researching the way the body sends signals about being cold, but she’s also writing a series of children’s books so kids from underrepresented minorities know they can be scientists.
Author and neuroscientist Theanne Griffith talks with Maddie about her children's book series, The Magnificent Makers, which follows two intrepid third graders as they race to complete science-based adventures.
Twelve early-career faculty members, that included the departmental faculty member, Mark Huising, Ph.D., are adding a new title after their names: Chancellor’s Fellow, in recognition of their outstanding work in academia. Each keeps the title for five years and receives $25,000 in philanthropic support for research or other scholarly work.

Jim was recognized for his work on the molecular and cellular mechanisms that control the expression, spatial distribution, and function of voltage-gated K+ channels and their associated signaling complexes in mammalian brain neurons. Congratulations to Jim and Colleen for this well-deserved recognition!
UC Davis researchers develop an easy pre-clinical test of cardiac safety
UC Davis Health researchers have developed a computer model to screen drugs for unintended cardiac side effects, especially arrhythmia risk.
Clancy is a recognized leader in using high-performance computing to understand electrical changes in the heart.
“One main reason for a drug being removed from the market is potentially life-threatening arrhythmias,” Clancy said. “Even drugs developed to treat arrhythmia have ended up actually causing them.”
The problem, according to Clancy, is that there is no easy way to preview how a drug interacts with hERG-encoded potassium channels essential to normal heart rhythm.
Marked Differences Between Males and Females

Growth at Cold Temperature Increases the Number of Motor Neurons to Optimize Locomotor Function
During vertebrate development spinal neurons acquire specialized identities and form a network that carries out sensorimotor functions. Intrinsic spontaneous electrical activity regulates different aspects of the birth and differentiation of spinal neurons. Whether environmental cues modulate electrical activity in developing spinal neurons and in turn influence their specialization and survival to generate the circuits underlying sensorimotor function remains unclear. Here we show that growing frog embryos at cold temperature results in swimming larvae with an increase in the number of spinal motor neurons compared to larvae raised in warm temperature. This change in spinal cord development optimizes the escape response to gentle touch of animals grown and tested at cold temperatures. The cold-sensitive channel TRPM8 increases Ca2+ spike frequency of developing ventral spinal neurons, which in turn regulates expression of the motor neuron master transcription factor HB9. TRPM8 is necessary for both the increase in motor neuron number of animals grown in cold temperatures and for their enhanced sensorimotor behavior when tested at cold temperatures. These findings suggest the environment modulates neuronal differentiation to optimize the behavioral outcome of the developing organism. Given that fetuses and preterm neonates lack mature thermoregulation, our findings suggest aberrant fluctuations in fetal or neonatal body temperature may impact neurodevelopment.
This new study from the Borodinsky lab, has been accepted and published in the journal Current Biology. Congratulations!!

Tuning Cardiac EC-coupling during Fight or Flight
New work from the Dixon lab revealing a new facet of β-adrenergic receptor (β -AR) mediated regulation of cardiac L-type calcium channels CaV1.2 appears in the current issue of The Journal of Physiology. The work demonstrates that stimulation of β-ARs with isoproterenol (ISO) induces a never before appreciated, rapid, dynamic increase in the expression and cooperative gating behavior of CaV1.2 channels in the sarcolemma of adult mouse ventricular myocytes. This striking response is PKA-dependent and manifests as the formation of CaV1.2 channel ‘super-clusters’ in response to ISO, in the t-tubule sarcolemma of these freshly isolated cells. Ito et al. demonstrate this with cutting-edge super-resolution imaging approaches in both fixed and live cells and study the functional implications with electrophysiology and Ca2+ imaging approaches. See this dynamic super-clustering occurring before your eyes in a particularly novel and exciting dataset recorded from live ventricular myocytes (view here). On the basis of these data, Ito et al. propose a revised model for β-AR-mediated regulation of CaV1.2 channels in the heart wherein a pre-synthesized pool of sub-sarcolemmal CaV1.2 channel- containing vesicles/endosomes resides in cardiomyocytes and can be mobilized to the sarcolemma to tune EC-coupling to meet metabolic and/or hemodynamic demands.
The article and accompanying ‘Perspectives’ commentary (written by William Louch) appears in the current issue of The Journal of Physiology.

Voltage Sensors Detained by Tarantula Venom
The Sack laboratory has published an article in the Journal of General Physiology determining the statistical thermodynamics underpinning the mechanism by which an especially powerful tarantula toxin prevents an ion channel from opening. They found that the sneaky spider toxin finds unsuspecting channels that are patiently resting, and binds to them such that they their voltage sensors can’t respond to physiological voltage changes anymore. The ion channels the toxin inhibits are important for a host of physiological functions including neuronal signaling, muscle contraction, and insulin secretion. This study of the toxin revealed new aspects of how the ion channels they bind work. Additionally, understanding precisely how the toxin works allows the many researchers who use this toxin for physiological research to understand what the toxin is actually doing to ion channels. This research also revealed new uses of the toxin: it can be used not just to block ion channel currents, but to immobilize their voltage sensors as well. This work was featured in a wonderfully thorough commentary in the Journal, which unpacks the physics and the relevance of the Sack laboratory’s findings.
The article and commentary are soon to be included in a special Journal of General Physiology issue, Molecular Physiology of the Cell Membrane: An Integrative Perspective from Experiment and Computation.

Digitizing interactions between the brain and the heart
UC Davis Health researchers have been awarded $5.2 million over four years from the National Institutes of Health to develop the first computerized model of the relationship between the nervous system and cardiovascular disease.
The tool is expected to lead to new understanding of conditions such as hypertension, arrhythmia, heart failure and stroke, along with how those conditions change in response to treatment.
“We know that imbalance between the nervous and cardiovascular systems contributes to heart disease, however we don’t fully understand how,” said principal investigator Colleen Clancy, professor of physiology and membrane biology. “Our new suite of tools will showcase those interactions in a real-time, visual way and could lead to new interventions for preventing and even reversing heart disease.”

A study from the Borodinsky lab is highlighted in the Journal of Neuroscience
The brain and spinal cord begin as a group of cells in the embryo that folds in on itself to form the neural tube. Some of the most common birth defects, such as spina bifida, are caused by a neural tube that fails to close completely. Against the prevailing view that the side effects of antiepileptic (AED) drugs contribute to the prevalence of neural tube defects among children of epileptic mothers, a study led by a former postdoctoral fellow, Eduardo Sequerra and a current UC Davis graduate student, Raman Goyal, from Dr. Laura Borodinsky's lab discovers that in frog embryos the neurotransmitter glutamate and N-methyl-aspartate (NMDA) receptors play an important part in the proliferation and migration of the cells that form the neural tube, which were compromised in embryos treated with the widely-used AED valproic acid and led to neural tube defects. Understanding the mechanisms of neurotransmitter signaling during neural tube formation may contribute to identifying and developing antiepileptic drugs that are safer during pregnancy.

Abstract: New JGP paper explains sexual dimorphism and tissue-specific activity of TRPV4.
The broadly expressed transient receptor potential vanilloid 4 (TRPV4) calcium channel allows an enormous amount of calcium into the cell (up to 100-fold greater calcium flux than those produced by voltage-gated Cav1.2 calcium channels; 1). In vascular smooth muscle, TRPV4 channels help regulate vascular tone. In this month’s JGP, Tajada et al. provide surprising new insights about how TRPV4 activity is regulated.

Ca2+ entry into neurons is facilitated by cooperative gating of clustered CaV1.3 channels
Voltage-gated calcium channels open in unison, rather than independently, to allow calcium ions into and activate excitable cells such as neurons and muscle cells, departmental chair and faculty member Luis Fernando Santana, Ph.D., along with researchers from his lab and the researchers from the University of Washington have found.
The research defies earlier electrophysiology canon and undermines the previously held belief that calcium channels function independently. The study is published online in the journal eLIFE.

Tarantula venom illuminates electrical activity in live cells
Researchers from Sack and Yarov-Yarovoy labs, Lawrence Berkeley National Laboratory and Marine Biological Laboratory in Woods Hole, Massachusetts, have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells. The probe binds to a voltage-activated potassium ion channel subtype, lighting up when the channel is turned off and dimming when it is activated.
This is the first time researchers have been able to visually observe these electrical signaling proteins turn on without genetic modification. These visualization tools are prototypes of probes that could some day help researchers better understand the ion channel dysfunctions that lead to epilepsy, cardiac arrhythmias and other conditions. The study appears in the Proceedings of the National Academy of Sciences (PNAS) on October 20.
