Tannic Acid Exhibits Antiangiogenesis Activity In Nonsmall-Cell Lung Cancer Cells, Elham Hatami, Prashanth K.B. Nagesh, Mohammed Sikander, Anupam Dhasmana, Subhash C. Chauhan, Meena Jaggi, Murali M. Yallapu

School of Medicine Publications

Nonsmall-cell lung cancer (NSCLC) is the most common type of lung cancer, with a dismal prognosis. NSCLC is a highly vascularized tumor, and chemotherapy is often hampered by the development of angiogenesis. Therefore, suppression of angiogenesis is considered a potential treatment approach. Tannic acid (TA), a natural polyphenol, has been demonstrated to have anticancer properties in a variety of cancers; however, its angiogenic properties have yet to be studied. Hence, in the current study, we investigated the antiproliferative and antiangiogenic effects of TA on NSCLC cells. The (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) (MTS) assay revealed that TA induced a dose- and time-dependent …

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 …

Two studies, by Hagihara et.al and Jansen and Walach respectively, discuss the potential benefits of KD …

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 …

Expanding The Role Of Occupational Therapy For Oncology Patients: A Focus On Tumor- And Blood-Based Cancers, Erika N. Clark

Occupational Therapy Capstone Presentations

Tumor and blood-based cancer diagnosis rates are increasing rapidly in the United States. To improve survivorship, treatment practices are constantly evolving, however, patients are often left to face the consequences of survival. With decreased range of motion, strength, and ability to participate in desired activities, patients may experience a decrease in overall quality of life. Through a holistic lens, occupational therapists are well suited to address the diverse needs of cancer patients through the duration of their cancer treatments. Unfortunately, occupational therapy remains a widely underutilized service for this population. This capstone experience worked to address this gap by expanding …

Epigenetics And Cancer: Mechanisms, Diagnostics, And Treatment, Sophie Kopyar

D.U.Quark

Epigenetics connects the divide between genotype and phenotype without completely altering the genome. Modifications to certain genes can affect cell functions and produce diseased phenotypes, such as cancer. In some forms of cancer, epigenetic changes cause the cell to irregularly reproduce, avoid immunological responses, and operate under unsuitable conditions. This review explores the epigenetic changes that can occur to produce an oxygen deficient, hypoxically functioning environment that increases cancer vitality. More specifically, this review will focus on epigenetic alterations to HIF and p53 genes and briefly cover other genes that can be affected in cancerous cells. This review found there …

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 …

The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez

Thinking Matters Symposium

In a clinical setting, some patients are exposed to an anti-cancer chemotherapy agent, paclitaxel. Cancerous cells undergo rapid, continuous cell division without control. Chemotherapy treatments try to slow and stop the uncontrollable cell division cycles and eliminate cancerous cells in the process. Paclitaxel serves as a treatment for some types of cancers, including lung, melanoma, bladder, and esophageal. Because it targets the cytoskeleton, paclitaxel can also influence cell migration. This project utilizes a cellular migration assay and an immunohistochemistry assay to analyze the effects of paclitaxel on the movement of cells and on the cytoskeleton of neuroglia rat cells with …

The Impact Of Dietary Fiber On Breast Cancer Incidence, Peyton North

Epsilon Sigma at-Large Research Conference

Abstract

Introduction & Background

The role of dietary fiber in breast cancer etiology remains unclear. A negative correlation may be due to fiber’s ability to stave off obesity and aid in the extraction of serum estrogen, two known risk factors for the disease. Effects may differ by source, and type, of fiber. Most of the data available is from research with non-Hispanic white women. However, fiber intake may vary significantly across cultures.

Purpose Statement & Question

The research sought to investigate whether an increased intake of dietary fiber was associated with a corresponding decrease in the incidence of breast cancer. …

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 Effects Of Floatation-Rest On Cortisol Levels Of Patients With Glioblastoma Grade Iv: A Conceptual Framework, Hilario Gomez

Selected Honors Theses

Glioblastoma is reported to be the most aggressive and common brain tumor in adults (Davis, 2016). To help alleviate pain in patients with glioblastoma, floatation-REST (Restricted Environmental Stimulation Technique) is proposed. Such therapy has been shown to benefit chronic tension headaches, muscle tension, and other stress-related pain conditions (Feinstein, 2018). The magnesium and sulfate components of Epsom salt combined with controlled warm water allow the muscles and joints to relax. Studies show that magnesium targets the Adrenocorticotropic Hormone (ACTH) produced by the Anterior Pituitary Gland which in turn affects cortisol hormone levels to activate the body's immune defenses and eliminate …

An Analysis Of The Psychological And Physical Effects Of A Physical Activity Program During In-Patient Pediatric Cancer Treatment, Zoë Winters

Undergraduate Theses

There is limited published research regarding the use of physical activity in cancer treatment programs, and even fewer in pediatric treatment plans; however, there is a common consensus that following the conclusion of cancer treatment an individual’s physical fitness has been majorly impacted. The inactivity that commonly coexists with cancer treatment often results in extended periods of time in rehabilitation programs and decreased independence. Along with the physical detriments caused by inactivity, increased dependence on others often brings about feelings of helplessness that can further cause emotional detriments. It has however been demonstrated in previous research that adding physical activity …
