Current And Emerging Uses Of Statins In Clinical Therapeutics: A Review, Jonathan T. Davies, Spencer F. Delfino, Chad E. Feinberg, Meghan F. Johnson, Veronica L. Nappi, Joshua T. Olinger, Anthony P. Schwab, Hollie I. Swanson

Pharmacology and Nutritional Sciences Faculty Publications

Statins, a class of cholesterol-lowering medications that inhibit 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, are commonly administered to treat atherosclerotic cardiovascular disease. Statin use may expand considerably given its potential for treating an array of cholesterol-independent diseases. However, the lack of conclusive evidence supporting these emerging therapeutic uses of statins brings to the fore a number of unanswered questions including uncertainties regarding patient-to-patient variability in response to statins, the most appropriate statin to be used for the desired effect, and the efficacy of statins in treating cholesterol-independent diseases. In this review, the adverse effects, costs, and drug–drug and drug–food interactions associated with statin …

Targeted And Controlled Anticancer Drug Delivery And Release With Magnetoelectric Nanoparticles, Alexandra Rodzinski

FIU Electronic Theses and Dissertations

A major challenge of cancer treatment is successful discrimination of cancer cells from healthy cells. Nanotechnology offers multiple venues for efficient cancer targeting. Magnetoelectric nanoparticles (MENs) are a novel, multifaceted, physics-based cancer treatment platform that enables high specificity cancer targeting and externally controlled loaded drug release. The unique magnetoelectric coupling of MENs allows them to convert externally applied magnetic fields into intrinsic electric signals, which allows MENs to both be drawn magnetically towards the cancer site and to electrically interface with cancer cells. Once internalized, the MEN payload release can be externally triggered with a magnetic field. MENs uniquely allow …

Pharmacy Faculty Articles and Research

A series of cyclic peptides containing a number of tryptophan (W) and glutamic acid (E) residues were synthesized and evaluated as pH-sensitive agents for targeting of acidic tissue and pH-dependent cytoplasmic delivery of molecules. Biophysical studies revealed the molecular mechanism of peptides action and localization within the lipid bilayer of the membrane at high and low pHs. The symmetric, c[(WE)4WC], and asymmetric, c[E4W5C], cyclic peptides translocated amanitin, a polar cargo molecule of similar size, across the lipid bilayer and induced cell death in a pH- and concentration-dependent manner. Fluorescently-labelled peptides were evaluated for targeting of acidic 4T1 mammary tumors in …

Design Of Nanoparticle-Based Carriers For Targeted Drug Delivery, Xiaojiao Yu, Ian Trase, Muqing Ren, Kayla Duval, Xing Guo, Zi Chen

Dartmouth Scholarship

Nanoparticles have shown promise as both drug delivery vehicles and direct antitumor systems, but they must be properly designed in order to maximize efficacy. Computational modeling is often used both to design new nanoparticles and to better understand existing ones. Modeled processes include the release of drugs at the tumor site and the physical interaction between the nanoparticle and cancer cells. In this paper, we provide an overview of three different targeted drug delivery methods (passive targeting, active targeting, and physical targeting) and compare methods of action, advantages, limitations, and the current stages of research. For the most commonly used …

Here we show rates for X-chromosome mosaicism are four times higher than mean autosomal rates; X mosaic events more often include the entire chromosome and participants with X events more likely harbour autosomal mosaic events. X mosaicism frequency increases with age (0.11% in 50-year olds; 0.45% in 75-year olds), as reported for Y and autosomes. Methylation array analyses …

Mechanism Of Action And Applications Of Interleukin 24 In Immunotherapy, Leah Persaud, Dayenny De Jesus, Oliver Brannigan, Maria Richiez-Paredes, Jeannette Huaman, Giselle Alvarado, Linda Riker, Gissete Mendez, Jordan Dejoie, Moira Sauane

Publications and Research

Interleukin 24 (IL-24) is an important pleiotropic immunoregulatory cytokine, whose gene is located in human chromosome 1q32-33. IL-24’s signaling pathways have diverse biological functions related to cell differentiation, proliferation, development, apoptosis, and inflammation, placing it at the center of an active area of research. IL-24 is well known for its apoptotic effect in cancer cells while having no such effect on normal cells. IL-24 can also be secreted by both immune and non-immune cells. Downstream effects of IL-24, after binding to the IL-20 receptor, can occur dependently or independently of the JAK/STAT signal transduction pathway, which is classically involved in …

Partner Interfering Behaviors Affecting Cancer Quality Of Life, Ann L. Coker, Diane R. Follingstad, Lisandra S. Garcia, Heather M. Bush

Obstetrics and Gynecology Faculty Publications

Objective: Because partners are an important and unpaid resource in cancer care, understanding how destructive, controlling or interfering partner behaviors influence women's cancer care may be particularly relevant for health care providers seeking to provide cancer care and enhance recovery. Using a new measure of partner interfering behaviors in cancer care (PIB-C), we investigated whether women with a recent cancer diagnosis who additionally endorsed any PIB-C would report (a) more symptoms of depression and stress, and (b) lower Functional Assessment of Cancer Therapy (FACT-G) and lower Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-SP) scale scores indicating poorer quality of …

Rural Disparities In Cancer Care: A Review Of Its Implications And Possible Interventions, Raj Singh, Lynne J. Goebel Md

Internal Medicine

Cancer care has greatly improved in the last few decades, as evidenced by a 22% decline in the overall cancer-related death rate in the United States since 1991. However, the question presents itself whether rural residents, for whom the latest advancements are not as accessible, are also realizing these benefits as much as their urban counterparts. The aim of this study is to provide are view of the literature regarding the disparities in cancer care facing rural Appalachia and specifically West Virginia (WV) as well as possible solutions towards bridging this gap. We find that WV has a higher cancer …

Inhibitions Of Gsk3Β Modulates Cell Death In Epithelial Ovarian Cancer, Noelle L. Cutter Ph.D., Tyler Walther Bsc, Naeha Pathak

Faculty Works: Biology, Chemistry, and Environmental Studies

Epithelial ovarian cancer is one of the most common gynecological malignancies and the fifth most frequent cause of cancer death in women, affecting over 22,000 women annually. Nearly 15,500 affected women die from this disease annually, and chemoresistance from the commonly prescribed platinum-based drug, carboplatin, is a major contributor to this mortality rate. Previous studies have identified genes with CpG islands that are methylated and transcriptionally silenced in resistant epithelial ovarian cancer patients. One of these genes is GSK3β, an important regulator of apoptosis and cell growth in the Wnt pathway. Thus, understanding the role of GSK3β suppression in chemoresistance …

Characterization And Target Identification Of Ak301: A Novel Mitotic Arrest Agent, Michael J. Bond, Avijeet S. Chopra, Marina Bleiler, Michelle Yeagley, Eric Scocchera

University Scholar Projects

The Giardina Laboratory has recently identified AK301 as a novel mitotic arrest agent. This work aimed to characterize the arrest state induced by AK301 (EC₅₀ ~ 150nM) and identify the cellar targets responsible for the arrest. It was found that AK301 arrest is readily reversible upon withdrawal of AK301. Cells that slip from mitosis after removal of AK301 are sensitized to apoptosis. This was found to be unique for AK301 when compared to other mitotic arrest agents like colchicine, vincristine, and BI2536. Arrested cells were found to have increased ATM activity as well as an upregulation of p53 and …

Molecular Mechanisms Of Squamous Cell Carcinoma Tumor Stem Cell Creation Via High Nitric Oxide (Hno) Adaptation, Niresh T. Kuganeswaran '16, Krishi Korrapati '17, Thomas Wan '16, Timothy Tamas, James A. Radosevich

Student Publications & Research

Cancer relapse or recurrence is defined as the return of cancer or its signs/symptoms after a period of improvement. Surgery may not remove all cancer cells and leave behind a few which cannot be detected by scans or other tests. It is also possible that some tumor cells are resistant to chemotherapy or radiation. Although many cancer cells are killed by these treatments, there may exist a few which contain a different genetic makeup which allows them to survive. These hypermalignant cancer cells, or cancer stem cells (CSCs), have been associated with causing cancer relapse. It has also been predicted …

Challenges Of Adoptive (T-)Cell Transfer Immunotherapy For Cancer, Aaron Volk

Biology: Student Scholarship & Creative Works

Background and significance: The rebirth of the theory of immunosurveillance in 2001 rejuvenated interest in anticancer immunotherapies. In particular, T-cell-based therapies have garnered substantial interest due to the robustness and tumor antigen-specific cytotoxicity of T-cell anticancer immune responses.

Hypothesis: The efficacy of adoptive cell transfer (ACT) T-cell immunotherapy could significantly improve and gain widespread approval if future innovations in ACT-based approaches account for the pro- and antitumoral properties of non-CD8⁺ lineages of effector T-cells, evasion of T-cell antitumor immunity, and tumor-induced suppression of antitumor immunity.

Problem Analysis: Despite numerous reports of highly successful ACT-based clinical trials, no such therapy …

Overcoming Cancer Multidrug Resistance Through Inhibition Of Microparticles, Sora Vysotski, Rivka Winzelberg, Mariana Babayeva

Touro College of Pharmacy (New York) Publications and Research

One of the main obstacles to success of chemotherapy agents is the development of cancer resistance. Cancer multidrug resistance (MDR) is thought to arise from over-expression of efflux transporters on cancer cells’ plasma membranes. Recently, microparticles (MP) were found to play a major role in mediating the resistance to antineoplastic agents. Microparticles can confer MDR phenotype to cancer cells though 3 complimentary pathways: 1) Intercellular transfer of P-gp and MRP1; 2) Intercellular transfer of regulatory nucleic acids that ensure acquisition of MDR phenotype; and 3) Internal sequestration of anticancer drugs to reduce the amount of free active drug. Compounds that …
