Confronting Cosmetic Carcinogens: A Proposal Regarding The Dangers Of Talcum Powder, Rachael Howell

Helm's School of Government Conference - American Revival: Citizenship & Virtue

The Federal Government needs to stop the import, export, mining, and distribution of talcum powder in the United States. This is an issue that affects all Americans, especially active-duty military members.

Since 2013, there have been over 38,000 lawsuits against Johnson & Johnson, which allege that their talcum-based baby powder caused cancer. The plaintiffs in the very first talc case in the U.S. have died. All four of the plaintiffs from a 2019 suit have died. Yet, the 2019 case has been reversed and remanded. The FDA has redacted the names of scientist(s) that conduct “safety tests” on talc samples. …

Anticancer Drug Screening Using Invitro Cell Proliferation Assay, Kristopher L. Ezell, Kyle Doxtater, Samantha Lopez, Sophia M. Leslie, Justin Wendel, Kamaldeep Paul, Vijay Lauxmi, Manish Tripathi

Research Colloquium

Introduction: In this presentation cell proliferation methods and how they are related to screening for effective chemotherapy drugs will be reviewed. Cancer in its most basic form is the unchecked mass dividing of cells while normal apoptosis is not undertaken for various reasons, some of which that have yet to be discovered. By these means’ tumors form that inhibit the functions of the organs it is residing in and the effected cells may metastasize and spread throughout the body. For this reason, chemotherapy drugs must be assessed through introduction into working strains of cultured cancer cells that are then screened …

Survival Disparities Between Border And Non-Border Counties In Colorectal Cancer Patients Using The Tcr, Michael Machiorlatti, Michael Brian Lapelusa

Research Colloquium

Along the US Texas Mexico border constant migration, developing medical infrastructure and income disparity leads to poorer access to healthcare and poorer health outcomes. Given 32 of the 254 counties in TX are on the border with roughly 9.8% of the Texas residing in these counties (2.8 million people), this represents a significant population susceptible to adverse health outcomes. We investigate comparisons between border and non-border counties as well as how sociodemographic and diagnostic criterion influence survival of colorectal cancer. Data was obtained from the Texas Department of State Health Service’s TCR. Patients were 18 or older and excluded for …

The Dual Delivery Of Y15 And Metformin In A Plga Scaffold For The Treatment Of Platinum Resistant Ovarian Cancer, Emily M. Jordan, Hannah Obregon, Arkene Levy, Sue Anne Chew

Research Symposium

Background: Ovarian cancer is the fifth leading cause of cancer mortality among women in the US. High mortality is linked to resistance to platinum compounds. Currently there is no treatment for platinum resistant ovarian cancer (OCpt). Platinum resistance shows increased activity of focal adhesion kinase (FAK). Y15 is a FAK inhibitor and increases OCpt sensitivity to chemotherapy. Metformin induces apoptosis, has no increased cytotoxicity, and works synergistically with Y15 in OCpt cells. Biomaterial scaffolds deliver drugs locally, maximizing drug concentration and bioavailability while minimizing systemic toxicity. PLGA copolymer has excellent biocompatibility, versatility, and a tailorable degradation rate. The objective of …

Research Symposium

Background: Health disparities in the lower Rio Grande Valley are well documented and can play a critical role in cancer prognosis. Chronic stress, arguably exacerbated by these disparities, can also lead to a poor outcome after diagnosis through dysregulation of molecular markers known to be involved in cancer progression, resistance, and recurrence. lncRNA have been a relatively recent point of interest in the field of cancer research and play a role in cancer initiation and progression across tissue types. We have found that lncRNA MALAT1 is stress induced through transcription factor NFATc1. Here, we propose to investigate the association of …

Precise Method To Identify Kinase Drug Targets In Complex Diseases: The First Step Towards Sustainable And Effective Treatment, Hasbanny Irisson, Marzieh Ayati

Research Symposium

Background: Kinases are enzymes that have proven to be important drug targets due to their role in critical biological mechanisms such as phosphorylation. Phosphorylation happens when a kinase catalyzes the transfer of a phosphate group to a protein in a phosphorylated site, which then becomes known as the substrate of the kinase. Any dysregulation of protein phosphorylation causes a wide range of complex diseases including cancer. Thus, discovering the links between kinases and their substrates (i.e. predicting kinase-substrate associations (KSAs)) is crucial in developing effective and sustainable treatments. Presently, less than 5% of phosphorylated sites have an associated kinase, and …

The purpose of this study was to identify sulfonamide analogues as CA inhibitors based on affinity and interactions of molecular docking.

Methods: Through structure and similarity-based virtual screening and applying filters involving a preselection based on functional group, Lipinski's rule of five, mutagenic and tumorigenic characteristics, the best candidates were docked into the isoenzymes. Known reference ligands were used to determine affinity regions favorable for …

Identification And Characterization Of Anticancer Potential Of A Novel Small Molecule, Mortaparibmild, Hazna Noor Meidinna, Anissa Nofita Sari, Sunil C. Kaul, Renu Wadhwa

Research Symposium

Background: The development of new anticancer drugs and treatment modalities form a priority research field. The tumor suppressor protein p53 is frequently mutated or functionally inactivated in a large variety of cancers. Its inactivation by mortalin, a member of the heat shock 70 protein family, has been shown to contribute to carcinogenesis. The small molecule inhibitors of mortalin-p53 interactions have been shown to reactivate p53 yielding apoptosis/growth arrest in cancer cells. Therefore, abrogators of mortalin-p53 interaction have emerged as possible new therapeutic anticancer reagents.

Methods: We performed chemical library screening based on the imaging of mortalin-p53 interaction, leading to the …

Characterization Of Oral Cavity And Oropharyngeal Cancer In The Texas Rio Grande Valley, Jared A. Sperling, Rachel Giese

Research Symposium

Background: Cancers of the oral cavity (OC) and oropharynx (OP) account for 3% of cancers diagnosed in the United States each year. A primary cause of death among the Hispanic population in the United States is cancer, accounting for 20% of annual mortality. The Rio Grande Valley (RGV) is a medically-underserved area of South Texas with a large Hispanic population facing health disparities. In this study, we examine the incidence and mortality of OC and OP cancer in the RGV.

Methods: CDC population-level incidence and mortality rate per 100,000 of OC/OP cancer among patients in the RGV counties of Hidalgo …

Characterization Of Epithelial Growth Factor Transcripts Identified In Crotalus Atrox Venom, Ivan Lopez, Ying Jia

Research Symposium

Epithelial Growth Factor (EGF) is the primary source in regeneration and stimulation of essential fibroblasts cells commonly found in epithelium. Studies have shown that snake venom components are becoming a growing factor in treating illnesses such as cancer, muscular dystrophy, chronic pain, blood pressure, blood clotting, etc. EGF in human cells contains a promising quaternary structure that can bind to snake venom metalloproteinases, proposing a means of activating biochemical responses through protein-protein interactions to regulate unwanted cellular functions. This supports promising research in achieving a greater understanding of regulation along cellular pathways through ligands, increasing the likelihood of targeting unwanted …

Mortaparibplus- A Novel Anticancer Small Molecule Abrogating Mortalin-P53 Interaction In Cancer Cells, Anissa N. Sari, Ahmed Elwakeel, Jaspreet K. Dhanjal, Vipul Kumar, Durai Sundar, Sunil C. Kaul, Renu Wadhwa

Research Symposium

Background. The cessation of tumor cell growth through cell cycle arrest and apoptosis is determined by p53, a tumor suppressor protein. However, the interaction between mortalin-p53 within cytoplasm/nucleus leads to the inactivation of p53 transcriptional activation function. The disruption of mortalin-p53 complex has been suggested as an approach for developing a potential anticancer drug.

Methods. A screening of a high-content chemical library was performed to determine a molecule with mortalin-p53-interaction disrupting characteristics. After four-rounds of visual assays, we discovered a triazole derivative (4-[(1E)-2-(2-phenylindol-3-yl)-1-azavinyl]-1,2,4-triazole, named Mortaparib^Plus) with a potential ability of disrupting mortalin-p53-complex. In this study, we recruited …

In-Vitro Validation Of Intratumoral Modulation Therapy For Glioblastoma, Abdulla Elsaleh

Undergraduate Student Research Internships Conference

Intratumoral modulation therapy (IMT) is a novel electrotherapy used to treat brain cancer tumours using electric fields applied directly to the tumours through implanted electrodes. Previous research has validated IMT's effectiveness and provided computer-simulated optimizations for IMT electric fields. This work validates these computer optimizations in-vitro, using a PCB construct to deliver electric fields, and bioluminescence imaging to assess cell viability.

We found electric field strength to correlate with cell viability, and found that rotating (phase-shifted) electric fields did not produce significant improvements in IMT efficacy. Future work will investigate different IMT frequencies and other parameters, while providing biological replicates …

Medicinal Plants And Herbs For Cancer Prevention, Madeline Mctigue, Julianna Goelzer, William Ranahan

Research Symposium

Modern medicine has yet to produce selective treatments for the vast majority of cancer types. Most chemotherapies, though complex, remain non-specific, and thus destroy healthy cells. Over 25% of cancer patients die from the effects of chemotherapy before the actual tumor would have progressed to the point of organismal death (Megget 2008). Early detection remains the most accurate indicator of successful treatment outcome. But why wait until the disease presents to deal with it? Here the authors argue that a well supported immune system coupled with a dietary regimen of key food-based medicines is a far superior strategy. Given that …

We report a case of acrometastasis to the left second phalanx in a 70-year-old woman with a history of invasive breast carcinoma that was in remission for four years. On initial encounter in the emergency department, she had pain and swelling over the proximal (PIP) and distal interphalangeal (DIP) joints with a lytic appearance on radiographs. A subsequent Adler PET scan demonstrated previously unknown metastatic disease in the right lower lung, mediastinal and hilar lymph nodes, …

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. …

Combination Chemo-Pdt Ionic Nanomedicines As Enhanced Therapeutics For Cancer, Samantha Macchi

Arkansas Women in STEM Conference

Cancer remains as one of the leading causes of death in humans worldwide. Nanotechnology has made great strides in improving treatment for the disease. This work describes a simplistic approach to design self-assembled combination nanomedicines. A facile one-step ion exchange reaction is utilized to combine a chemotherapeutic (phosphonium) cation and photodynamic therapeutic (porphyrin) anion. An aqueous nanomedicine is prepared from the hydrophobic ionic combination drug via a single-step reprecipitation method. Upon conversion to ionic combination drug, improved photophysical properties of porphyrin were observed. These characteristics subsequently led to increased photodynamic therapeutic activity of nanomedicines—explained by greater singlet oxygen quantum yield. …

In Patients With Hepatocellular Carcinoma (Hcc) (P), Is Bevacizumab With Atezolizumab (I) More Effective Than Sorafenib (C) In Long-Term Clinical Prognosis (O)?, Joon Lee

Capstone Showcase

Hepatocellular carcinoma (HCC) is the third leading cause of cancer death globally. China contributes to half of the global incidence of liver cancer, with about 70-85% being HCC. Definitive treatment for this condition would be surgical resection with liver transplant but for obvious reasons, the majority of affected patients are unable to meet the necessary criteria. Sorafenib is a form of chemotherapy that has been the mainstay treatment of HCC since its approval in 2007. More recently, the combination of Bevacizumab and Atezolizumab has shown greater efficacy in the treatment of unresectable HCC. Additionally, this new combination therapy shows favorable …
