The university’s BIO5 Institute, which connects hundreds of researchers in different disciplines to address complex challenges, was able to swiftly respond to the pandemic and release a round of seed funding via the Technology and Research Initiative Fund, which will enable researchers to positively impact the health of Arizonans and combat the global pandemic through their efforts.

Over the next six months, the researchers – BIO5 Institute members representing seven UArizona colleges – will use TRIF funds to understand the lifecycle of the novel coronavirus, identify potential treatments and create patient databases to expand understanding of the disease, among other goals.

“Innovative faculty are working together to research how the virus spreads and infects people, developing new therapeutics and creating programs to foster health and well-being,” said Jennifer Barton, director of the BIO5 Institute.

TRIF was established through Proposition 301, approved by Arizona taxpayers in November 2000 to raise the Arizona sales tax by 0.6%. Revenue generated by this mechanism is vital to supporting university research and innovation, in addition to K-12 education and community college workforce programs.

In response to the pandemic, TRIF funds were quickly allocated to create a COVID-19 seed grant program. Proposals for interdisciplinary basic science, technology, clinical or population research that directly address COVID-19 were accepted from UArizona teams of two or more researchers.

Applications were reviewed based on three criteria: the potential to make an immediate COVID-19 impact, the collaboration and teamwork of the applicants, and the use of UArizona core facilities in addressing research questions.

“In addition to funding these seed grants, TRIF support has enabled the University of Arizona to be ready to address this kind of global threat because of the research services infrastructure and core facilities that it has allowed us to build up over the last 19 years,” Barton said.

Of the 55 seed grant applicants, 13 interdisciplinary groups were funded. With funds to support technical staff, postdoctoral researchers, graduate students and resources to perform analyses, researchers will address the pandemic from several angles.

 

Understanding the evolution of a virus

One team, representing the College of Medicine – Tucson, will investigate the evolution of the virus. Samuel Campos, associate professor of immunobiologyScott Boitano, professor of  physiology; and Ken Knox, professor of medicine, will investigate how the evolutionary adaptation of a key viral structure may have enabled this novel strain to cause rapid worldwide disease.

 

Identifying prevention or treatment strategies for COVID-19

Curtis Thorne, assistant professor of cellular and molecular medicine, and Koenraad Van Doorslaer, assistant professor in the College of Agriculture and Life Sciences, will use image-based screening techniques to identify compounds that may interfere with the ability of the virus to infect and cause long-lasting infections.

Van Doorslaer will also work with Michael Johnson, assistant professor of immunobiology, to investigate the use of copper compounds in preventing infection.

Equally important to preventing new infections is treating existing ones.

Two anti-malarial drugs, chloroquine and hydroxychloroquine, are currently being investigated as COVID-19 treatments, though their utility and safety is uncertain. College of Pharmacy assistant professor Jianqin Lu and professor Xinxin Ding will aim to improve delivery, enhance efficacy and minimize toxicity of these drugs.

Lu also will work with Yin Chen, associate professor in the College of Pharmacy, to investigate whether immune system activation can treat COVID-19 patients.

Another team – College of Pharmacy professor Wei Wang and associate professor Steffan Nawrocki, along with associate professor of medicine Jennifer Carew – will test novel inhibitors of the viral lifecycle in treating existing infections.

 

Epidemiological and public health approaches to the pandemic

A team representing medicine, pharmacy and the Mel and Enid Zuckerman College of Public Health will use patient data from Banner – University Medical Center Tucson and area family medicine clinics to create a local COVID-19 database. The team includes Karen Lutrick, assistant professor in the College of Medicine – Tucson; Dean Billheimer, professor of public health; and Brian Erstad, professor in the College of Pharmacy.

A second database will be generated by researchers Kristen Pogreba-Brown and Kate Ellingson, both assistant professors of public health, along with public health professor Elizabeth Jacobs, public health associate professor Kacey Ernst and Pamela Garcia-Filion, associate research scientist in the Department of Biomedical Informatics at the University of Arizona College of Medicine – Phoenix.

Produced from patient interviews, the database will provide a catalog of risk factors and patient symptoms that can be used by all Arizona investigators addressing COVID-19.

Another epidemiological study, led by Michael Worobey, professor and head of the Department of Ecology and Evolutionary Biology, and David Baltrus, associate professor of plant sciences, aims to understand the genetics of viruses that have infected Southern Arizona patients. Through these efforts, researchers representing the College of Science and College of Agriculture and Life Sciences will seek to understand the relationship of the Arizona outbreak to the national epidemic.

Vignesh Subbian, assistant professor in the College of Engineering, will work with Dr. Jarrod Mosier, associate professor in the College of Medicine – Tucson, to compile characteristics of hospitalized COVID-19 patients in Arizona.

In addition to creating databases, UArizona researchers will address public health concerns by exploring relationships between COVID-19, pre-existing health conditions and the environment.

Older adults and those with existing critical health conditions seem to be at greater risk for COVID-19. Dr. Janko Nikolich-Žugich, head of the Department of Immunology, and associate professor Deepta Bhattacharya will work with Dr. Craig Weinkauf, assistant professor in the Department of Surgery, to find out why.

The virus has been shown to be present in the feces of infected individuals, and these live viruses can become airborne in wastewater treatment plants. A team of four researchers at the UArizona Water and Energy Sustainable Technology Center – environmental science assistant research professors Luisa Ikner and Walter Betancourt, public health professor Kelly Reynolds and environmental science professor Ian Pepper – will work with Jeff Prevatt, deputy director of the Pima County Regional Wastewater Reclamation Department, to study the risk of the airborne virus to facility worker health.

 

Mental health and social isolation

COVID-19 affects more than just physical health; social isolation can increase anxiety and negatively impact mental health. Judith Gordon, professor and associate dean of research for the College of Nursing, and Chris Gniady, associate professor in the Department of Computer Science, will address the behavioral health consequences of COVID-19 through a guided imagery app.

“Together, the preliminary data collected through these TRIF-supported seed grants will not only address COVID-19 from the perspective of viral infection, prevention and treatment, but will also create resources that will prove useful in combatting this global pandemic,” said Elizabeth “Betsy” Cantwell, UArizona senior vice president for research and innovation. “TRIF has allowed University of Arizona assets like the BIO5 Institute to immediately respond to critical research needs associated with grand health and environmental challenges to improve outcomes for the people of Arizona and make a difference in our world.”
