Title: Mechanisms of Chemotherapy-Induced Cognitive Impairment

PI: Antiño R. Allen, PhD

Associate Professor

Division of Radiation Health

UAMS – College of Pharmacy

Chemotherapy-induced cognitive impairment, colloquially termed as ‘chemobrain’, is a poorly understood phenomenon affecting a highly variable proportion of both male and female cancer patients as well as survivors of all ages and many chemotherapy regimens.  Chemobrain symptoms can persist for years post-chemotherapy, and some patients never regain their previous quality of life.  Using genetic models and pharmacologic approaches, our work examines how the changes in the neuronal microenvironment e.g. inflammation, oxidative stress affects neurogenesis and cognitive function after exposure to Breast Cancer and Juvenile Acute Lymphoblastic Leukemia chemotherapy.

Dr. Adam Wolfe SRI Bio

Title: Targeting DNA Repair to Overcome Radiation Resistance in Pancreatic Cancer

PI: Adam Wolfe, MD, PhD

Assistant Professor

Department of Radiation Oncology

UAMS – College of Medicine

The Wolfe Lab investigates DNA repair pathways leading to treatment resistance to radiation therapy, novel DNA damage radiation biomarkers, and the development of novel DNA repair targets to improve responses to radiation therapy. We are interested in understanding the molecular drivers of radiation resistance. Our main disease of focus is pancreatic cancer. We utilize genetic and proteomic approaches to address the fundamental mechanisms of genetic alterations in cancer cells, resulting in heightened DNA repair leading to radiation resistance. We have developed relevant in vitro and in vivo models of human cancer that mimic the disease phenotype in the patients.

Dr. Alicia K. Byrd Bio

Title: Mechanisms of genome maintenance by HELB

PI: Alicia K. Byrd, PhD

Assistant Professor

Department of Biochemistry and Molecular Biology

UAMS – College of Medicine

HELB is a DNA helicase whose overexpression is associated with reduced survival in glioma but increased survival in melanoma. HELB is involved in DNA repair and cancer therapy resistance.  DNA repair affects genome instability, which is a hallmark of cancer cells. Despite this, the mechanisms by which HELB affects genome instability are not well defined. Using cellular and in vitro approaches, our lab is studying the molecular mechanism by which HELB increases genome stability after stalling of DNA replication.

Dr. Analiz Rodriguez

PI: Analiz Rodriguez MD, PhD

Associate Professor (effective 7/1/22)

Department of Neurosurgery 

The Rodriguez lab investigates glioblastoma and metastatic brain tumors. Patients with these tumors typically have less than a year and a half to live after diagnosis.  The laboratory uses next generation sequencing and proteomics to identify novel targets and understand tumor progression. Patient-derived organoid models are also used to validate candidate targets and understand brain tumor growth. Dr. Rodriguez is also interested in health care disparities and how to improve access to surgical interventions for brain tumor patients.

Dr. Darin E. Jones Bio

PI: Darin E. Jones, PhD

Associate Professor

Department of Pharmaceutical Sciences

UAMS – College of Pharmacy

We develop small molecule inhibitors and chemical tool compounds of essential proteins involved in DNA repair to provide a greater understanding of the mechanisms of DNA repair and of chemotherapeutic drug resistance.  We have identified selective inhibitors of poly(ADP-ribose) glycohydrolase (PARG), a monogenic enzyme that removes the poly(ADP-ribose) posttranslational modification of proteins modified by PARP1.  A genetic knockdown of PARG sensitizes cells to DNA damage and phenocopies the effects of PARP1 enzymatic inhibitors in BRCA-deficient cells.  In this project, we improve the potency and selectivity of small molecule PARG inhibitors through structure-guided chemical synthesis and testing in vitro, and advance selected compounds to preclinical trials of tumor killing activity in cultured cells and xenograft models of breast and ovarian cancer.

Title: Viruses and the type-1 interferon response

PI: Karl W. Boehme, Ph.D.

Associate Professor

Department of Microbiology & Immunology

UAMS – College of Medicine

Type-1 interferons are a component of the innate immune system that are critical for controlling viruses. Viral infection causes the production of type-1 interferons, which interfere with viral replication and limit viral disease. We use mammalian orthoreovirus (reovirus) as a model to uncover how viruses trigger the type-1 interferon response during infection, as well as how viruses overcome type-1 interferon responses to replicate efficiently. Ongoing work in the lab combines genetic, biochemical, and cell biological approaches to investigate these questions in cell culture. We also explore the role of type-1 interferons in viral disease using mice as a small animal model.

Dr. Nukhet Aykin-Burns

TITLE:  Determining efficacy of tocotrienols against lead toxicity.

PI: Nukhet Aykin-Burns, PhD

Associate Professor,

Department of Pharmaceutical Sciences

UAMS – College of Pharmacy

The neurotoxicity of lead has been well established through numerous studies. However, the cellular processes of lead neurotoxicity, as well as techniques to prevent or reverse cellular damage after lead exposure, remain unknown. Oxidative stress plays a primary role in lead-induced neurotoxicity, thus antioxidants should assist in reviving lead-exposed cells. This project will explore different isoforms of tocotrienols as antioxidant agents in PC-12 cells after lead exposure. Selective oxidative stress parameters, including glutathione (GSH), glutathione disulfide (GSSG) and mitochondrial function will be measured in PC-12 cells exposed to various concentrations of lead acetate.

STUDENT’S RESPONSIBILITIES-DUTIES IN THE PROPOSED PROJECT:

The student will be responsible for learning sterile tissue culture technique and methods to measure oxidative stress markers using spectrophotometry and extracellular flux analysis

Dr. Robert Eoff Bio

Title: Mechanisms of DNA damage tolerance in response to replication stress

PI: Robert L. Eoff, PhD

Professor

Department of Biochemistry and Molecular Biology

UAMS – College of Medicine

Barriers to DNA replication can arise from endogenous and exogenous sources. Cells have evolved a variety of mechanisms that allow timely resumption of impaired fork progression. Our laboratory studies the molecular mechanisms that allow tolerance of endogenous fork barriers, such as G-quadruplexes (G4), and bypass of DNA damage induced by exogenous agents, such as genotoxic cancer therapies (e.g., ionizing radiation and chemotherapy). We are interested in determining the molecular features and biochemical properties that govern these processes. We are also focused on understanding how cells choose between translesion DNA synthesis (TLS) and other replication stress response (RSR) mechanisms. A long-term goal is to leverage our knowledge of the RSR as a means of developing new therapeutic strategies for the treatment of glioblastoma and other deadly forms of cancer.

Title: Study of connective tissue diseases caused by alterations in collagens.

PI: Roy Morello, Ph.D.

Associate Professor

Department of Physiology & Cell Biology, Orthopaedic Surgery, and Division of Genetics

UAMS – College of Medicine

Summary: My research interests consist in genetic aspects and pathogenesis of human disease, with a focus on skeletal dysplasias and in the biology and function of collagens. We use laboratory mice with the objective to learn from the animal model and make correlations with relevant aspects of human disease to gain mechanistic insights of biological function. I have developed significant experience in the phenotypic, histological, imaging and molecular characterization of skeletal and non-skeletal defects in a variety of mouse models that phenocopy human syndromes, including Osteogenesis imperfecta (OI) but also Nail-Patella (NPS) and Ehlers-Danlos syndrome (EDS). The current focus is to study the impact of type I collagen alterations on the skeleton and the respiratory system in mouse models of OI.

Title: Sensitizing cancer cells to radiation with mevalonate pathway inhibitors

PI: Rupak Pathak, PhD

Assistant Professor

Division of Radiation Health

UAMS – College of Pharmacy

Radiation therapy effectively suppresses tumor growth, but concurrently cause damage to the normal healthy tissues. Normal tissue toxicity is one of the major dose-limiting factors. Therefore, strategies for radiation dose reduction are required without compromising its therapeutic efficacy. Mevalonate pathway inhibitors limit cholesterol biosynthesis and are used to treat cardiovascular diseases. Our preliminary data shows mevalonate pathway inhibitors suppress proliferation of various cancer cells. Here, we seek to determine whether various mevalonate pathway inhibitors enhances the potency of radiation to control cancer cell proliferation and define the underlying molecular mechanisms.

Title: The role of tumor vasculature in carcinogenesis and treatment

PI: Ruud P.M. Dings, Ph.D, M.Sc. (He/Him)

Assistant Professor

Department of Radiation Oncology

UAMS – College of Medicine


The primary goal of our lab is to enhance our understanding of vascular biology to discover and develop improved methods for cancer treatment. Our major research interest is the tumor microenvironment, with emphasis on the crosstalk between the immune system and the tumor vasculature. Our objective is to identify and delineate unexplored mechanisms to positively contribute to the vascular biology field and improve treatment strategies. We use multi-disciplinary techniques that include cellular and molecular biology approaches (e.g. aseptic techniques, flow cytometry, PCR, ELISA and others) using patient samples and mouse models to decipher cancer initiation and progression, and the treatment thereof.

Dr. Tremaine Williams SRI BIO

Project title: Quantifying Clinical Team Social Network Influences on Care of Patients with Multimorbidity

PI: Tremaine Williams. Ed.D.

Assistant Professor,

Department of Biomedical Informatics

UAMS – College of Medicine

Broadly, Dr. Williams’ research focuses on testing interventions addressing the organizational and behavioral determinants of clinical information quality on multimorbidity patient care outcomes with the target of improving the design and usability of the electronic medical record. Nationally, 81% of Americans age 65 years and older and 50% of Americans age 45 to 65 are living with multiple chronic conditions (MCC). MCC prevalence in Arkansas has been ranked as the second highest of all 50 states among adults between the ages of 18 to 45. The state of MCCs not only poses a critical risk for individual health, but it is increasingly recognized as a risk to value-based care and population health due to the enormous care-related costs. With regard to spending, the top five percent of medically complex patients account for nearly 50 percent of the nation’s spending on health care.  Through this project, we examine patient care team networks [social network analysis] as predictors of care outcomes [hospitalizations, Days-at-home/Days-between-hospitalizations, high cost encounters] to evaluate predictors of risk and increased care utilization. Outcomes drive the development and refinement of computational tools that support clinical management and mitigation of risk.

Dr. Michael Bauer, PhD

Project title: Multi-omic Approaches Towards Understanding Cancer Biology

PI: Michael Bauer, PhD

Assistant Professor,

Department of Biomedical Informatics

UAMS – College of Medicine

My work focuses on furthering the understanding of cancer biology with the inclusion of multiple types of molecular data. These data types include epigenetic information, whole genome and RNA sequencing and using bioinformatic approaches to combine these genomic modalities to get a more complete picture of the cancer biology. Recent work has involved investigating the largely unexplored process of alternative splicing and lncRNA and their role in Multiple Myeloma. To that end, I am looking to incorporate third-generation sequencing, also known as long-read sequencing, which as the name denotes sequence considerably longer DNA and RNA fragments. These long sequences enable unambiguous identification of rare or novel transcripts, gene fusion events, and complex genomic rearrangements without the need for assembly. Additionally, long read sequencing can capture base modifications of both DNA and RNA, which provides a mechanism to interrogate both epigenomics and epitranscriptomics along with genomics and transcriptomics. Together with this cutting-edge technology and cell-lines, mouse models and patient data I will apply multi-omic analysis to get answers to important cancer biology questions such as mechanism of drug resistance, relapse, and patient risk stratification.

Project title: Physical fitness, nutrition, and sleep in relation to childhood development

PI: Eva C. Diaz Fuentes

Assistant Professor,

Department of Pediatrics, Department of Nutrition Section

UAMS – College of Medicine

Physical activity and nutrition are major determinants of health and childhood development. My research focuses on evaluating the complex interactions of nutrition, physical fitness, and sleep in relation with childhood health and development. Human studies involving school age are ongoing at the Arkansas Children’s Nutrition Center (ACNC). Our studies aim to evaluate how physical fitness, nutrition, and sleep impact metabolic and bioenergetic health of children. Study participants attend ACNC where measures of physical fitness  (body composition, strength, aerobic capacity, etc.),  physical activity, sleep, bioenergetics, indirect calorimetry, and metabolic health are conducted in the clinical and laboratory settings. There is opportunity to do data analysis if of interest.
