School of Medicine Publications and Presentations

Glioblastoma multiforme (GBM) is one of the deadliest cancers of the brain. Its ability to infiltrate healthy brain tissues renders it difficult to remove surgically. Furthermore, it exhibits high rates of radio- and chemoresistance, making the survival rates of patients with GBM poor. Therefore, novel effective therapies for GBM remain urgently in demand. Niclosamide is an anti-helminthic drug and recently it has been receiving attention due to its reported anticancer effects in cancer models, including GBM. Furthermore, camptothecin (CPT) is a naturally-occurring alkaloid and has been previously reported to be a potential chemotherapeutic agent by targeting the nuclear topoisomerase I. …

The Future Of Targeted Kinase Inhibitors In Melanoma, Signe Caksa, Usman Baqai, A E Aplin

Department of Cancer Biology Faculty Papers

Melanoma is a cancer of the pigment-producing cells of the body and its incidence is rising. Targeted inhibitors that act against kinases in the MAPK pathway are approved for BRAF-mutant metastatic cutaneous melanoma and increase patients' survival. Response to these therapies is limited by drug resistance and is less durable than with immune checkpoint inhibition. Conversely, rare melanoma subtypes have few therapeutic options for advanced disease and MAPK pathway targeting agents show minimal anti-tumor effects. Nevertheless, there is a future for targeted kinase inhibitors in melanoma: in new applications such as adjuvant or neoadjuvant therapy and in novel combinations with …

Identification Of Translesion Synthesis Inhibitors That Target Rev7/Rev3 Protein-Protein Interactions, Seema Patel

Honors Scholar Theses

Translesion synthesis (TLS) is a cellular mechanism utilized by cancer cells to tolerate DNA damage caused by chemotherapeutics, like cisplatin, by replicating past unrepaired lesions. This increases the rate of mutations, which leads to the emergence of drug-resistant cancer cells. Preliminary studies have shown that disrupting the protein-protein interactions (PPI) in the TLS heteroprotein complex increases cells’ sensitivity to first-line genotoxic chemotherapy, illustrating how inhibiting TLS assembly and function can significantly increase cancer cell death. These results underscore the therapeutic potential of targeting TLS PPI. Our current work in this area is focusing on inhibitors capable of disrupting the Rev7/Rev3 …

Foundations Of Plasmas For Medical Applications, T. Von Woedtke, Mounir Laroussi, M. Gherardi

Electrical & Computer Engineering Faculty Publications

Plasma medicine refers to the application of nonequilibrium plasmas at approximately body temperature, for therapeutic purposes. Nonequilibrium plasmas are weakly ionized gases which contain charged and neutral species and electric fields, and emit radiation, particularly in the visible and ultraviolet range. Medically-relevant cold atmospheric pressure plasma (CAP) sources and devices are usually dielectric barrier discharges and nonequilibrium atmospheric pressure plasma jets. Plasma diagnostic methods and modelling approaches are used to characterize the densities and fluxes of active plasma species and their interaction with surrounding matter. In addition to the direct application of plasma onto living tissue, the treatment of liquids …

Dnp Final Report: Psychosocial Screening For Oncology Patients, Robyn V. Beard

DNP Final Reports

Background: Patients with cancer often face severe distress related to fear of death, body disfigurement, financial stress, and lack of support system. This distress may lead to physical and emotional symptoms that bring patients to seek care at emergency departments, delay care or make poor health choices, and increase utilization of prescription drugs. With the already over burdened healthcare system, addressing these psychosocial needs is vital to improving patients outcomes as well as improving healthcare expenditure. Purpose: The purpose of this evidence based practice project was to improve perceived quality of life for oncology patients through detailed screening and behavioural …

Targeted Osmotic Lysis: A Novel Approach To Targeted Cancer Therapies, Harry J. Gould, Dennis Paul

School of Medicine Faculty Publications

The conventional treatment of cancer has been based on the delivery of non-selective toxins and/or ionizing energy that affect both the cancer and normal tissues in the hope of destroying the offending disease before killing the patient. Unfortunately, resistance often develops to these treatments and patients experience severe, dose-limiting adverse effects that reduce treatment efficacy and compromise quality of life. Recent advances in our knowledge of the biology of tumor cells and their microenvironment, the recognition of surface proteins that are unique to specific cancers and essential to cell growth and survival and signaling pathways associate with invasion and metastasis …

The Role Of Mtorc1 In Autophagy As It Relates To Cancer, Olivia Robinson

Senior Honors Theses

The mammalian target of rapamycin complex 1, mTORC1, is composed of several subunit proteins with many cellular responsibilities including participation in a complex cell signaling cascade leading to autophagy, which is the regulated degradation of cell components. mTORC1 is frequently mutated or dysregulated within human cancer. Normally, mTORC1 functions to provide efficient regulation of autophagy according to intracellular levels of growth factors, amino acids, nutrients, oxygen levels, and more that can either inhibit mTORC1 and upregulate autophagy or activate mTORC1 and downregulate autophagy. A better understanding of mTORC1 is imperative to preparing cancer therapy treatments. Various cancerous tissue types require …

Survivorship Research For People With Metastatic Or Advanced Cancer: A Time For Action, Andrea L. Smith, Nicolas H. Hart, Michael Jefford, Raymond J. Chan

Research outputs 2022 to 2026

Over recent decades, survival outcomes for people diagnosed with cancer have changed dramatically, with approximately 20% improvement in five-year relative survival rates in high-income countries including the United States and Australia. Regardless of regions, there is a decrease in overall cancer mortality rate of about 1% per year. Likewise, the cancer disease trajectory has changed. The traditional linear cancer trajectory in which a patient moves from cancer diagnosis through to a binary outcome (cure or death)—is no longer applicable and does not adequately describe the complexity of experience for many people. Indeed, the availability of targeted therapies and immunotherapies has …

T Cell Therapy: Underlying Mechanisms And Current Advancements, Griffin Mccloy

Senior Honors Theses

As the second leading cause of death in 2016, cancer is one of the most serious diseases facing the world today. T cell therapy is a current area of research attempting to address the disease with two primary division: CAR-T and TCR-T cell therapy. The immune system naturally produces T lymphocytes to aid in the recognition and removal of cells infected with viruses or transformed into cancer. Under normal circumstances, T lymphocytes identify and destroy cancerous cells; however, some cancerous cell types can evade this system. With the use of genetic editing technology, T lymphocytes can gain the ability to …

A Machine Learning Framework For Identifying Molecular Biomarkers From Transcriptomic Cancer Data, Md Abdullah Al Mamun

FIU Electronic Theses and Dissertations

Cancer is a complex molecular process due to abnormal changes in the genome, such as mutation and copy number variation, and epigenetic aberrations such as dysregulations of long non-coding RNA (lncRNA). These abnormal changes are reflected in transcriptome by turning oncogenes on and tumor suppressor genes off, which are considered cancer biomarkers.

However, transcriptomic data is high dimensional, and finding the best subset of genes (features) related to causing cancer is computationally challenging and expensive. Thus, developing a feature selection framework to discover molecular biomarkers for cancer is critical.

Traditional approaches for biomarker discovery calculate the fold change for each …

Challenges And Opportunities For Immunotherapeutic Intervention Against Myeloid Immunosuppression In Glioblastoma, Mark A Exley, Samantha Garcia, Amelia Zellander, Jenny Zilberberg, David W. Andrews

Department of Neurosurgery Faculty Papers

Glioblastoma multiforme (GBM), the most common and deadly brain cancer, exemplifies the paradigm that cancers grow with help from an immunosuppressive tumor microenvironment (TME). In general, TME includes a large contribution from various myeloid lineage-derived cell types, including (in the brain) altered pathogenic microglia as well as monocyte-macrophages (Macs), myeloid-derived suppressor cells (MDSC) and dendritic cell (DC) populations. Each can have protective roles, but has, by definition, been coopted by the tumor in patients with progressive disease. However, evidence demonstrates that myeloid immunosuppressive activities can be reversed in different ways, leading to enthusiasm for this therapeutic approach, both alone and …

Dna-Pkcs: A Targetable Protumorigenic Protein Kinase., Emanuela Dylgjeri, Karen E Knudsen

Department of Cancer Biology Faculty Papers

DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is a pleiotropic protein kinase that plays critical roles in cellular processes fundamental to cancer. DNA-PKcs expression and activity are frequently deregulated in multiple hematologic and solid tumors and have been tightly linked to poor outcome. Given the potentially influential role of DNA-PKcs in cancer development and progression, therapeutic targeting of this kinase is being tested in preclinical and clinical settings. This review summarizes the latest advances in the field, providing a comprehensive discussion of DNA-PKcs functions in cancer and an update on the clinical assessment of DNA-PK inhibitors in cancer therapy.

Department of Medical Oncology Faculty Papers

Background: Older adults (≥65 years) with gastrointestinal (GI) cancers who receive chemotherapy are at increased risk of hospitalization caused by treatment-related toxicity. Geriatric assessment (GA) has been previously shown to predict risk of toxicity in older adults undergoing chemotherapy. However, studies incorporating the GA specifically in older adults with GI cancers have been limited. This study sought to identify GA-based risk factors for chemotherapy toxicity-related hospitalization among older adults with GI cancers.

Patients and methods: We performed a secondary post hoc subgroup analysis of two prospective studies used to develop and validate a GA-based chemotherapy toxicity score. The incidence of …

Positive Selection And Enhancer Evolution Shaped Lifespan And Body Mass In Great Apes, Daniela Tejada-Martinez, Roberto A Avelar, Inês Lopes, Bruce Zhang, Guy Novoa, João Pedro De Magalhães, Marco Trizzino

Department of Biochemistry and Molecular Biology Faculty Papers

Within primates, the great apes are outliers both in terms of body size and lifespan, since they include the largest and longest-lived species in the order. Yet, the molecular bases underlying such features are poorly understood. Here, we leveraged an integrated approach to investigate multiple sources of molecular variation across primates, focusing on over 10,000 genes, including approximately 1,500 previously associated with lifespan, and additional approximately 9,000 for which an association with longevity has never been suggested. We analyzed dN/dS rates, positive selection, gene expression (RNA-seq), and gene regulation (ChIP-seq). By analyzing the correlation between dN/dS, maximum lifespan, and body …

All Works

Vitamin D3 has many important health benefits. Unfortunately, these benefits are not widely known among health care personnel and the general public. As a result, most of the world’s population has serum 25-hydroxyvitamin D (25(OH)D) concentrations far below optimal values. This narrative review examines the evidence for the major causes of death including cardiovascular disease, hypertension, cancer, type 2 diabetes mellitus, and COVID-19 with regard to sub-optimal 25(OH)D concentrations. Evidence for the beneficial effects comes from a variety of approaches including ecological and observational studies, studies of mechanisms, and Mendelian randomization studies. Although randomized controlled trials (RCTs) are generally considered …

Ultrasound 96 Probe Device Protocol For Cancer Cell Treatment, Aisling Field, Brijesh K. Tiwari, James F. Curtin, Julie R M Mondala, Janith Wanigasekara

Articles

Ultrasound is a sound wave with frequencies ranging between 20 kHz and 20 MHz. Ultrasound is able to temporarily and repeatedly open the BBB safely and enhance chemotherapeutic delivery without adverse effects. This novel technique in drug delivery benefits from the powerful ability of ultrasound to produce cavitation activity. Cavitation is the generation and activity of gas-filled bubbles in a medium exposed to ultrasound. As the pressure wave passes through the media, gas bubbles expand at low pressure and contract at high pressure. This leads to oscillation which produces a circulating fluid flow known as microstreaming around the bubble with …

Research outputs 2022 to 2026

Purpose: Cancer-induced muscle wasting (i.e., cancer cachexia, CC) is a common and devastating syndrome that results in the death of more than 1 in 5 patients. Although primarily a result of elevated inflammation, there are multiple mechanisms that complement and amplify one another. Research on the use of exercise to manage CC is still limited, while exercise for CC management has been recently discouraged. Moreover, there is a lack of understanding that exercise is not a single medicine, but mode, type, dosage, and timing (exercise prescription) have distinct health outcomes. The purpose of this review was to examine the effects …

Interferon-β (IFN-β) is a pleiotropic cytokine secreted in response to various pathological conditions and is clinically used for therapy of multiple sclerosis. Its application for treatment of cancer, infections and pulmonary diseases is limited by incomplete understanding of regulatory mechanisms of its functioning. Recently, we reported that IFN-β activity is affected by interactions with S100A1, S100A4, S100A6, and S100P proteins, which are members of the S100 protein family of multifunctional Ca2+-binding proteins possessing cytokine-like activities (Int J Mol Sci. 2020;21(24):9473). Here we show that IFN-β interacts with one more representative of the S100 protein family, the S100B protein, involved in …
