Proposal Title: The role of the ER stress-inducible ribosome-binding protein 1 (RRBP1) in cardiomyocyte protection during ischemic stress 

BIO5 Member & Principal Investigator: Shirin Doroudgar, Department of Internal Medicine, UArizona College of Medicine – Phoenix  

Heart problems caused by narrowed heart arteries, or ischemic heart disease, can affect the signaling pathways and survival of the cardiac muscle cells responsible for the contraction of the heart. It's critical to understand the molecular mechanisms of these cells and pathways to prevent cell death and the resulting stress placed on the cardiovascular system. 

With a background in medical physiology, immunology, and cell biology, Marjan Aghajani is pursuing a research career focused on studying abnormal changes in body functions caused by cardiovascular disease.  

“I want to understand how cardiac muscle cells, or myocytes, respond to stressful challenges. My vision is that such responses could become the basis of new therapies for heart diseases that stress cardiac myocytes,” said Aghajani.  

Aghajani will use the BIO5 Postdoctoral Fellowship to study the molecular mechanisms involved in ischemic heart disease. Using human induced pluripotent stem cells (hiPSCs), she will focus on the role of ribosome-binding protein 1 (RRBP1) in cardiomyocyte survival under ischemic stress. The funds and mentorship will help her gain expertise in hiPSC culturing and differentiation and present her work at a heart research conference. 

Angela (Angie) Greenman, PhD 

Proposal Title: Quantifying the super-relaxed state of myosin 

BIO5 Member & Principal Investigator: Samantha Harris, Department of Physiology, UArizona College of Medicine – Tucson 

Understanding the molecular mechanisms of muscle contraction can lead to a better outcome of hypertrophic cardiomyopathy (HCM), a prevalent cause of heart failure in adults.  

Using her expertise in molecular biology, physiology, and muscle function, Angie Greenman plans to use her BIO5 Fellowship to further her career goals of becoming an independent scientist studying and teaching how skeletal and cardiac muscle function in health, disease, and under the stress of exercise. 

"I want to study the effects that cardiac and skeletal muscle proteins have on regulating contraction and relaxation in normal physiology and testing these same proteins under the stress of pathology and under the demands of exercise,” said Greenman.  

Greenman will use the BIO5 Postdoctoral Fellowship to expand her laboratory skills, particularly in fluorescent microscopy techniques related to muscle function, to study the role of cardiac myosin binding protein-C (cMyBP-C) in muscle contraction and relaxation. Funding will allow her to visit with an expert in the field at the University of Copenhagen, learning novel techniques for characterizing different states of myosin during relaxation that opens doors to new avenues of research in her field.   

Atsushi Ishii, MD, PhD 

Proposal Title: Gaining tools to probe the dynamics of brain stem cell regeneration during aging 

BIO5 Member & Principal Investigator: Lalitha Madhavan, Department of Neurology, UArizona College of Medicine – Tucson 

Understanding the effects of aging and sex hormones on neurogenesis is important for a deeper understanding of various cranial nerves and psychiatric diseases. Some central nerve diseases develop in a variety of age-dependent manners and go into spontaneous remission, while others, such as autism spectrum disorder, develop from birth and progress chronically, and others, such as Parkinson's disease and Alzheimer's disease, develop in old age. Some symptoms develop and progress over time, and symptoms change with age. 

With his long-standing interests in neurological disorders and a background working as a pediatric neurologist, Atsushi Ishii wants to research regenerative approaches for addressing age-related neurological disorders. 

“Working on neurodevelopmental disorders previously in a clinical setting, I became intrigued with the role of age-dependent changes in these contexts, which although important, were less appreciated and studied,” said Ishii. 

Ishii will use the BIO5 Postdoctoral Fellowship to investigate the molecular pathways associated with the aging of neural stem progenitor cells (NSPCs), particularly focusing on the NRF2 transcription factor and its interaction with sex hormones. He plans to visit an expert in the field at Tohuku University in Japan to learn about NRF2 biology and cutting-edge methods, as well as attend a conference around stem cell research to network and present his work.  

David Jordan, PhD 

Proposal Title: Preliminary biomechanical evaluation of the concurrency of carpal tunnel syndrome and trapeziometacarpal osteoarthritis 

BIO5 Member & Principal Investigator: Zong-Ming Li, Department of Orthopedic Surgery, UArizona College of Medicine – Tucson 

Millions of people are afflicted with carpal tunnel syndrome and osteoarthritis, musculoskeletal disorders of the hand and wrist. 

David Jordan's mechanical engineering expertise, along with his background in physiology, bioengineering, medical imaging, and computer modeling, gives him a unique multidisciplinary perspective on the biomechanical study of the hand and wrist. 

“My current research focus involves the imaging, testing and modeling of the trapeziometacarpal joint, which is the most affected hand joint by osteoarthritis. I aim to develop novel therapeutic treatment mechanisms for this disorder,” said Jordan. 

Using the BIO5 Postdoctoral Fellowship funds, Jordan will study the concurrency of carpal tunnel syndrome and osteoarthritis. He wants to identify and recruit patients with concurrent cases of these disorders and construct apparatuses for testing hand function. Jordan also plans to attend conferences focusing on orthopedic research and biomechanics to jumpstart his independent research career. 

Zoe Lyski, PhD 

Proposal Title: Uncovering mechanisms behind suboptimal immunity in immunocompromised individuals 

BIO5 Member & Principal Investigator: Deepta Bhattacharya, Department of Immunology, UArizona College of Medicine – Tucson 

As the ongoing COVID-19 pandemic has shown, people do not develop equally protective immune responses to infection and vaccination, and those with immunocompromising conditions and cancer are especially at risk. 

With expertise in immunology and virology, Zoe Lyski will use the BIO5 Postdoctoral Fellowship to further study how immune responses influence viral evolution.  

“There is an unmet need to uncover key drivers of suboptimal immunity and develop means of improving vaccine immune responses in immunocompromised patients. My project aims to help fill this knowledge gap,” said Lyski. 

Her project supported by the BIO5 Postdoctoral Fellowship will focus on understanding suboptimal immunity in cancer patients, particularly regarding antibody responses to vaccination and subsequent viral evolution. Funds will help develop targeted mRNA vaccine approaches to improve outcomes in immunocompromised patients and allow her to travel and present her research at an immunology conference.  

Gemma Purser, PhD 

Proposal Title: Investigating the role of urban forest soils in mitigating atmospheric volatile organic compound driven air pollution in cities 

BIO5 Member & Principal Investigator: Laura Meredith, School of Natural Resources and the Environment, College of Agriculture, Life & Environmental Sciences 

Volatile organic compounds (VOCs) contribute to air pollution, which has implications for human health particularly in urban areas. The presence of VOCs in the atmosphere has a variety of sources, but of rising concern are those originating from personal care items, cleaning products, and industrial solvents.

Specializing in atmospheric and analytical chemistry, Gemma Purser wants to further her understanding of microbial analysis and urban ecosystems to better study VOCs.  

“This fellowship offers a unique opportunity to explore critical questions at the intersection of urban ecology, atmospheric chemistry, and microbiology. I am excited about the potential impact of this research on understanding the role of urban forest soils in buffering the newly emerging sources of atmospheric volatile organic compounds in cities,” said Purser.  

Using funds from the BIO5 Postdoctoral Fellowship, Purser will start a collaborative independent research project with Urban Biogeochemistry program at Boston University and Aerodyne Research, Inc. (ARI) to study the interplay between urban green spaces and volatile organic compounds in improving air quality. She will use the funds to conduct soil experiments using advanced mass spectrometer instrumentation at ARI and work with Boston University to further develop her microbial analysis techniques. 

Philip Yost, PhD 

Proposal Title: Biomimetic 5-module chimeric antigen receptor therapy 

BIO5 Member & Principal Investigator: Michael Kuhns, Department of Immunology, UArizona College of Medicine – Tucson

When our immune system works correctly, it deploys T cells to detect and eliminate viruses, bacteria, and other organisms that cause disease. However, sometimes these cells go rogue, attacking healthy cells and causing autoimmune diseases such as Type 1 diabetes. 

With an extensive background in cellular and developmental biology, Philip Yost wants to have a meaningful impact on human health research using a novel approach – biomimetic engineering – to genetically engineer cells that can lead to new immunotherapy treatments. 

“Since joining the Kuhns lab in fall 2022, I have successfully established a workflow for a second-generation chimeric antigen receptor as a platform to expand from just the treatment of Type 1 diabetes and extend as an application for treatments against other diseases,” said Yost. 

Yost will use the BIO5 Postdoctoral Fellowship to design and develop a second-generation biomimetic chimeric antigen receptor (CAR) for T-cells in immunotherapy, capable of redirecting T-cells effectively. He will use the funds to enhance his immunology training through advanced courses and attending conferences.  

Ran Zhang, PhD 

Proposal Title: A fluorescence-based high throughput screening assay to target the Nsp14 ExoN of SARS-CoV-2 

BIO5 Member & Principal Investigator: Hongmin Li, Department of Pharmacology & Toxicology, R. Ken Coit College of Pharmacy 

Emerging and evolving coronaviruses present challenges to researchers as they must continually advance their understanding of antiviral therapies.  

With her expertise in veterinary medicine, microbiology, and virology, Ran Zhang aims to provide valuable insights into potential antiviral drug development for coronaviruses. 

“Given the current global emphasis on antiviral research, particularly considering recent pandemics, there's a heightened demand for professionals with specialized knowledge in antiviral drug development. I want to contribute to groundbreaking discoveries that can have a profound effect on public health,” said Zhang. 

With the BIO5 Postdoctoral Fellowship, Zhang will research the role of non-structural protein 14 (nsp14) in coronaviruses' replication, particularly SARS-CoV-2, and develop a high-throughput screening assay to identify inhibitors of nsp14 activity. The funds and mentorship allow Zhang to design, implement, and test experiments that will help her understand viral replication mechanisms and add to the development of antiviral therapies.

With its focus on strengthening translational research, fostering collaborative projects and training the next generation of scientists, the BIO5 Institute aims to leverage its resources to advance interdisciplinary bioscience research and increase industry connections in Phoenix.
Caroline Mosley, BIO5 Institute

The BIO5 Institute at the University of Arizona is set to embark on a groundbreaking journey by officially expanding its footprint to Phoenix. This move marks a significant step in fostering collaborative biosciences research across Arizona and beyond. 

“The vision for the BIO5 Institute in Phoenix is to become a catalyzing force for interdisciplinary biosciences research, magnifying connections between Phoenix-based and Tucson-based BIO5 members, utilizing BIO5 resources, and integrating with the larger Arizona biosciences community,” said Jennifer Barton, BIO5 Institute director. 

While the BIO5 Institute already has over a dozen faculty members in Phoenix, the formal expansion to Phoenix is not just a geographical milestone, but a testament to the institute's dedication to advancing biosciences research through collaboration, innovation, and education. 

An open house mixer on November 13 in Phoenix officially launched the expansion by welcoming over 60 members of the UArizona community along with industry professionals. To forge strong relationships with both faculty and the biosciences industry, the BIO5 Institute hired a strategic engagement coordinator, Marissa Starks-Bahn, earlier this year who will be housed at the UArizona Biomedical Sciences Partnership Building. 

“Our goal is to grow our BIO5 membership in Phoenix while providing the same level of services a Tucson member may receive. In addition, we want to play a larger role in connecting our existing Phoenix and Tucson BIO5 members with UArizona resources as well as industry expertise,” said Barton. “We will also be able to better support UArizona Phoenix-based initiatives such as the Center for Advanced Molecular and Immunological Therapies (CAMI) and educational program expansion.” 

Increasing opportunities for translational research 

Strengthening and expanding translational research is a key initiative for the BIO5 Insitute, aligning with the Technology and Research Initiative Fund (TRIF) funding that helped launch the institute over 20 years ago. This special investment in higher education by Arizona voters is intended to expand major efforts in biomedicine and biotechnology that will provide a return on investment to the people of Arizona. 

A BIO5 member since 2017, Melissa Herbst-Kralovetz and her lab aim to positively impact women’s health by conducting biomedical research with a high translational value in a clinical setting.

Melissa Herbst-Kralovetz has been a BIO5 member for over six years and directs a program focused on women's health at the University of Arizona College of Medicine – Phoenix.

One current project in the Herbst-Kralovetz lab is endometrial cancer, the 4th most common cancer in women, that can only be diagnosed through painful and invasive procedures.  

Rising obesity rates and an aging female population, two main risk factors, are causing increasing rates of endometrial cancer, particularly in Arizona. But obtaining funding can be difficult for research that isn’t focused on pregnancy and childbirth. 

“Visibility is key for increasing awareness about gaps in women’s health research, particularly aging and menopause, two topics that are understudied,” said Herbst-Kralovetz, a professor in the Departments of Basic Medical Sciences and Obstetrics and Gynecology and director of the Women's Health Microbiome Initiative at the UArizona College of Medicine – Phoenix. "A few years ago, I accompanied Jennifer Barton to the governor’s office to ask for additional funding and support for the BIO5 Institute. That was a great opportunity to discuss the needs in women’s health research here in Arizona and why it needs to be prioritized in terms of funding.” 

She hopes the expansion of the BIO5 Institute’s footprint will lead to more opportunities for her to discuss her research with government officials as well as raising awareness of women’s health conditions within the Phoenix community. 

Jumpstarting critical research and training the next generation 

Another of the BIO5 Institute's key initiatives is providing its faculty members with opportunities for seed grant funding. These smaller grants are crucial support for galvanizing scientific projects that can lead to larger grants and more long-term stability for interdisciplinary research. This strategic approach has proven to be a catalyst for innovation and propelled the institute to the forefront of biosciences research. 

Taben Hale, a professor in the Department of Basic Medical Sciences at the UArizona College of Medicine – Phoenix, joined the BIO5 Institute in 2023. She studies the causes and consequences of high blood pressure to identify novel treatment strategies to allow people to live longer and healthier lives.

Taben Hale has been with the UArizona College of Medicine – Phoenix for over 15 years, but as a more recent member of the BIO5 Institute, she's interested to look into funding focused on jumpstarting collaborative projects.

“I’m excited to bridge disciplines and tap more broadly into academic and industry connections as a BIO5 member,” said Hale. “Opportunities to get seed grants are critical for stimulating those collaborative projects and generating the preliminary data that is necessary to then obtain federal funding.” 

Furthermore, the BIO5 Institute is committed to shaping the future workforce of scientists through programs like the KEYS Research Internship, the BIO5 Institute’s flagship summer internship program for high school students interested in developing STEM skills under the mentorship of UArizona scientists. Plans to integrate KEYS in Phoenix are already being discussed. 

Another way to prepare the future workforce is providing financial support and mentorship for up-and-coming researchers. Now in its fifth year, the BIO5 Postdoctoral Fellowship is an internal funding mechanism for postdoctoral researchers engaged in research projects aligned with the institute’s mission. The fellowship has already supported several outstanding postdoctoral fellows in Phoenix, 2023 fellow Nicole Jimenez and 2022 fellow Erik Blackwood, with hopes to support more.   

All these initiatives not only nurture emerging talent but also contribute to the institute's overarching goal of advancing biosciences research in Tucson, Phoenix and beyond.
