Curcumin is a golden-yellow flavonoid compound derived from the turmeric plant root that has been used in Chinese and Indian medicine for centuries. Curcumin has been shown to have antioxidant and anti-inflammatory properties, and because of this, has been gaining traction in the field of cancer research. Breast cancer is the most commonly diagnosed cancer in women, and is the second leading cause of cancer death in women, next to lung cancer. Because of the prevalence and mortality of breast cancer, possible therapeutics must be investigated. Due to the beneficial properties of curcumin and pervasiveness of breast cancer, we have …

Determining Effective Treatment Regimens For Breast Cancer Using Combined Immunotherapy And Chemotherapy In Vivo, Akhila Kunuthuru

Auctus: The Journal of Undergraduate Research and Creative Scholarship

Breast cancer has the highest incidence rate of all cancers globally in women, and those of African descent, especially West African females, face higher rates of triple-negative breast cancer (TNBC), a more aggressive form of breast cancer. Immunotherapy for breast cancer is a relatively new treatment option, and research is ongoing to identify the best combination treatments for increasing survival of those diagnosed with TNBC. Eganelisib (IPI-549: a PI3K-gamma inhibitor that works to shift M2 macrophages to M1 to augment T cell function) with other combinatory treatments has shown promising results in reducing tumor growth and increasing survival in mice. …

Research Symposium

Los cánceres de pulmón, próstata e hígado se encuentran entre los más prevalentes en los hombres. El cáncer de mama, de cuello uterino y de tiroides se encuentran entre los más prevalentes en mujeres (OMS, 2019). El tratamiento del cáncer generalmente incluye quimioterapia y radioterapia; sin embargo, los medicamentos contra el cáncer disponibles tienen una selectividad baja y causan efectos adversos graves, como nefrotoxicidad, neurotoxicidad y mielosupresión (Matsuo et al., 2010). Por tanto, el diseño y desarrollo de compuestos como nuevos agentes anticancerígenos frente a los tipos de cáncer de mayor incidencia son de vital importancia en el campo de …

Parabens Promote Protumorigenic Effects In Luminal Breast Cancer Cell Lines With Diverse Genetic Ancestry, Jazma L. Tapia, Jillian C. Mcdonough, Emily L. Cauble, Cesar G. Gonzalez, Dede K. Teteh, Lindsey S. Treviño

Health Sciences and Kinesiology Faculty Articles

Context

One in 8 women will develop breast cancer in their lifetime. Yet, the burden of disease is greater in Black women. Black women have a 40% higher mortality rate than White women, and a higher incidence of breast cancer at age 40 and younger. While the underlying cause of this disparity is multifactorial, exposure to endocrine disrupting chemicals (EDCs) in hair and other personal care products has been associated with an increased risk of breast cancer. Parabens are known EDCs that are commonly used as preservatives in hair and other personal care products, and Black women are disproportionately exposed …

Defying The Darkness: Countering Cancer With Light, Travis Hankins

Honors Theses

Triple-Negative Breast Cancer (TNBC) accounts for upwards of 15% of reported breast cancer cases. This subtype of breast cancer poses a greater threat to those diagnosed as compared to other types of breast cancer due to the lack of treatment options available. Additionally, TNBC grows and spreads faster, tends to be more aggressive, and has a greater chance of recurrence than its counterparts. Altogether, TNBC cases generally have a worse prognosis over other types of breast cancer. Photodynamic therapy (PDT) is currently being researched as a way to treat TNBC. Photodynamic therapy agents are light-activated materials used for localized disease …

Combination Treatment With Cdk4/6 And Cdk8/19 Inhibitors In Er-Positive Breast Cancer, Samantha Tolentino Safa

Senior Theses

Cyclin-dependent kinases (CDK) 4 and 6 are the main drivers of proliferation in estrogen receptor (ER)-positive breast cancer cells. CDK4/6 inhibitors, such as the FDA-approved cytostatic drug, Palbociclib, induce G1 arrest and prevent cell cycle progression. Prolonged treatment with CDK4/6 inhibitors can lead to drug resistance in the clinic as well as in the lab. The mechanisms behind this resistance are varied, with preliminary evidence suggesting that it may be influenced by the senescence-associated secretory phenotype (SASP), CDK6 hyperactivation, or degradation of the retinoblastoma protein (Rb). In contrast to the cell cycle mediating CDK4/6, CDK8 and 19 are involved in …

Selinexor Hyperactivates Akt And Induces Its Nuclear Accumulation, Erin Lawrence

Honors Scholars Collaborative Projects

Selinexor is currently being used in several clinical trials for cancer and has shown anti-cancer effects in combination with other chemotherapies. Clinical trials evaluating the use of selinexor in the treatment of triple negative breast cancer are limited, but in vitro studies show promising results in its ability to kill triple negative breast cancer cells. The mechanism by which this occurs, however, is not understood. The goal of this research was to determine the mechanism by which selinexor kills BT- 549 triple negative breast cancer cells.

Pharmacy Faculty Articles and Research

Small interfering RNA (siRNA) therapy is a promising approach for treatment of a wide range of cancers, including breast cancers that display variable phenotypic features. To explore the general utility of siRNA therapy to control aberrant expression of genes in breast cancer, we conducted a detailed analysis of siRNA delivery and silencing response in vitro in 6 separate breast cancer cell models (MDA-MB-231, MDA-MB-231-KRas-CRM, MCF-7, AU565, MDA-MB-435 and MDA-MB-468 cells). Using lipopolymers for siRNA complexation and delivery, we found a large variation in siRNA delivery efficiency depending on the specific lipopolymer used for siRNA complexation and delivery. Some lipopolymers were …

Amphiphilic Peptides For Efficient Sirna Delivery, Saghar Mozaffari, Emira Bousoik, Farideh Amirrad, Robert Lamboy, Melissa Coyle, Ryley Hall, Abdulaziz Alasmari, Parvin Mahdipoor, Keykavous Parang, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

A number of amphiphilic cyclic peptides—[FR]4, [WR]5, and [WK]5—containing hydrophobic and positively-charged amino acids were synthesized by Fmoc/tBu solid-phase peptide methods and evaluated for their efficiency in intracellular delivery of siRNA to triple-negative breast cancer cell lines, MDA-MB-231 and MDA-MB-468, in the presence and absence of 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE). Among the peptides, [WR]5, which contains alternate tryptophan (W) and arginine (R) residues, was found to be the most efficient in the delivery of siRNA by improving the delivery by more than 3-fold when compared to other synthesized cyclic peptides that were not efficient. The data also showed that co-formulation of [WR]5 …

Discrimination Of Breast Cancer From Benign Tumours Using Raman Spectroscopy, Fiona Lyng, Damien Traynor, Thi Nguyet Que Nguyen, Aidan Meade, Fazle Rakib, Rafif Al-Saady, Erik Goormaghtigh, Khalid Al-Saad, Mohamed H. Ali

Articles

Breast cancer is the most common cancer among women worldwide, with an estimated 1.7 million cases and 522,000 deaths in 2012. Breast cancer is diagnosed by histopathological examination of breast biopsy material but this is subjective and relies on morphological changes in the tissue. Raman spectroscopy uses incident radiation to induce vibrations in the molecules of a sample and the scattered radiation can be used to characterise the sample. This technique is rapid and non-destructive and is sensitive to subtle biochemical changes occurring at the molecular level. This allows spectral variations corresponding to disease onset to be detected. The aim …

The Effects Of Inhibiting Pi3k On Tumor Suppressor Gene P53 And Cell Proliferation, Kelsi Peters

Undergraduate Theses and Capstone Projects

When the cell surface molecule, Human EGF Receptor (HER2), is overexpressed, the cell can become cancerous. MDA-MB-453 is an established breast cancer cell line made cancerous by HER2 overexpression. This mutation that causes HER2 overexpression affects the cell signaling pathway of phosphoinositide 3-kinase (PI₃K), Akt, MDM2, and p53. We predicted that PI₃K would be inhibited with the compound, LY294002, sending signals for Akt and MDM2 to be deactivated in MDA-MB-453 cells. Deactivated MDM2 signals for p53 to be activated. P53 is a tumor suppressor protein that exists in low quantities in normal cells, but when damage …

Structure-Based Drug Design Of Novel Therapeutics Targeting Oncostatin M, Kelsey Skluzacek

Boise State University Theses and Dissertations

At 30% of all new diagnoses, the most prevalent malignancy for women is breast cancer, which in the United States will result in an estimated 266,000 new cases this year alone. Of the patients diagnosed with breast cancer, approximately 10-15% will develop distant metastases within three years of the initial detection of a primary tumor. For comparison, the five-year survival rate for localized breast cancer is 99%, whereas, the survival rate for metastatic breast cancer drops drastically to only 27%. The significant difference in survival rates is indicative of a need for a novel treatment strategy for metastatic breast cancer. …

Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi

LSU Master's Theses

Taxanes are spindle poisons that bind to and stabilize microtubules resulting in mitotic arrest. Herpes simplex Typ-1 (HSV-1) virions utilize the microtubular network for intracellular transport during both virus entry and virus egress from infected cells. It has been reported previously that taxanes may synergize with oncolytic herpes simplex viruses in the treatment of experimental prostate and breast tumors in mice. Other reports have indicated that taxanes may inhibit viral replication in infected cells. In this study the previously characterized Oncolytic Herpes Simplex Virus type 1 (OSVP), which was constructed in Kousoulas lab was used in conjugation with paclitaxel (taxol) …

Development Of Polyvinylpyrrolidone/Paclitaxel Self-Assemblies For Breast Cancer, Pallabita Chowdhury, Prashanth K.B. Nagesh, Sheema Khan, Bilal B. Hafeez, Subhash C. Chauhan, Meena Jaggi, Murali M. Yallapu

School of Medicine Publications and Presentations

The goal of this investigation was to develop and demonstrate a polymer/paclitaxel self-assembly (PTX-SA) formulation. Polymer/PTX-SAs were screened based on smaller size of formulation using dynamic light scattering analysis. Additionally, fluorescence microscopy and flow cytometry studies exhibited that polyvinylpyrrolidone (PVP)-based PTX-SAs (PVP/PTX-SAs) had superior cellular internalization capability in MCF7 and MDA-MB-231 breast cancer cells. The optimized PVP/PTX-SAs exhibited less toxicity to human red blood cells indicating a suitable formulation for reducing systemic toxicity. The formation of PVP and PTX self-assemblies was confirmed using fluorescence quenching and transmission electron microscopy which indicated that the PVP/PTX-SAs were spherical in shape with an …

Characterization Of Murine Breast Cancer Cell Lines For Anti-Cancer Vaccine, Haven N. Frazier

Biological Sciences Undergraduate Honors Theses

Breast cancer is the most commonly diagnosed cancer in women and the second leading cause of cancer death among women in the United States (1). While treatments involving radiation and chemotherapy currently exist, disease must be detected early in order for the treatments to be somewhat effective, and there is no effective treatment after metastasis occurs (2). Additionally, current therapies do not mitigate tumor immunosuppression. Decreasing the tumor-associated immunosuppressive conditions while activating antitumor immunity could prevent recurrence and metastasis, possibly leading to an effective treatment for cancer (3). Tumor cell vaccines could possibly address this issue and have become a …

Steroid Hormone Receptors As Prognostic Markers In Breast Cancer, Maggie C. Louie, Mary B. Sevigny

Faculty Publications & Research of the TUC College of Pharmacy

Despite the existence of many promising anti-cancer therapies, not all breast cancers are equally treatable, due partly to the fact that focus has been primarily on a few select breast cancer biomarkers- notably ERα, PR and HER2. In cases like triple negative breast cancer (ERα-, PR-, and HER2-), there is a complete lack of available biomarkers for prognosis and therapeutic purposes. The goal of this review is to determine if other steroid receptors, like ERβ and AR, could play a prognostic and/or therapeutic role. Data from various in vitro, in vivo, and clinical breast cancer studies were examined …

A Meta-Analysis Of Incidence And Risk Factors Of Trastuzumab-Induced Cardiotoxicity In Breast Cancer, Zeeshan Ali Jawa, Ruth M. Perez, Lydia Garlie, Maharaj Singh, Rubina Qamar, Bijoy K. Khandheria, Arshad Jahangir, Yang Shi

Maharaj Singh

Background: A monoclonal antibody, trastuzumab targets the human epidermal growth factor receptor 2 (HER2) oncogene that is overexpressed in 25–30% of breast cancers. In combination with first-line therapy, trastuzumab resulted in significant improvement in survival outcomes for those with HER2-positive metastatic breast cancer. Due to its improvement in outcome and prolonged survival, trastuzumab has been established as standard of care in both adjuvant and metastatic settings. However, along with common adverse events, trastuzumab has been found to be associated with cardiotoxicity. An estimated 1–4% of patients treated with trastuzumab will develop heart failure and ~10% of patients will experience a …

Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, Peican Zhu, Hamidreza Montazeri Aliabadi, Hasan Uludag, Jie Han

Pharmacy Faculty Articles and Research

The investigation of vulnerable components in a signaling pathway can contribute to development of drug therapy addressing aberrations in that pathway. Here, an original signaling pathway is derived from the published literature on breast cancer models. New stochastic logical models are then developed to analyze the vulnerability of the components in multiple signalling sub-pathways involved in this signaling cascade. The computational results are consistent with the experimental results, where the selected proteins were silenced using specific siRNAs and the viability of the cells were analyzed 72 hours after silencing. The genes elF4E and NFkB are found to have nearly no …

The Effect Of All-Trans Retinoic Acid And Fatty Acids On Mcf-7 Breast Cancer Cell Progression, David Brown

David C. Brown

Vitamin A metabolites and retinoids may slow the progression of breast cancer and elicit anti-neoplastic properties similar to those of omega-3 fatty acids. Studies using animal models show a decrease in the incidence, growth and metastisis of mammary tumors in the presence of specific fatty acids. This effect is also seen with use of retinoids, specifically all-trans retinoic acid (AtRA). Thus, fatty acids may also alter retinoid homeostasis in mammary carcinoma cells (MCF-7s). The potential for inter/co dependency among fatty acids and retinoids is considerable, and here it has been hypothesized that a decrease in cancer progression will occur in …

Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig

Dissertations & Theses (Open Access)

The crucial role of microRNAs (miRNAs) in cancer pathobiology has driven the introduction of new drug development approaches such as miRNA inhibition. In order to advance miRNA-therapeutics, there is a need to develop screening strategies that can target tumors in a specific way. Small molecule inhibitors represent an attractive approach to pursue this. However, the absence of molecular structures for most of the miRNAs makes it very difficult to predict which inhibitors can bind to them. Herein we designed a strategy to screen for small molecules by assesing whether they could directly bind/ interact with miR-10b/miR-21. As part of our …

Real-Time Detection Of Breast Cancer Cells Using Peptidefunctionalized Microcantilever Arrays, Hashem Etayash, Keren Jiang, Sarfuddin Azmi, Thomas Thundat, Kamaljit Kaur

Pharmacy Faculty Articles and Research

Ligand-directed targeting and capturing of cancer cells is a new approach for detecting circulating tumor cells (CTCs). Ligands such as antibodies have been successfully used for capturing cancer cells and an antibody based system (CellSearch®) is currently used clinically to enumerate CTCs. Here we report the use of a peptide moiety in conjunction with a microcantilever array system to selectively detect CTCs resulting from cancer, specifically breast cancer. A sensing microcantilever, functionalized with a breast cancer specific peptide 18-4 (WxEAAYQrFL), showed significant deflection on cancer cell (MCF7 and MDA-MB-231) binding compared to when exposed to noncancerous (MCF10A and HUVEC) cells. …

A Potential Mechanism For Extracellular Matrix Induction Of Breast Cancer Cell Normality, Robert D. Bruno, Gilbert H. Smith

Medical Diagnostics & Translational Sciences Faculty Publications

Extracellular matrix proteins from embryonic mesenchyme have a normalizing effect on cancer cells in vitro and slow tumor growth in vivo. This concept is suggestive of a new method for controlling the growth and spread of existing cancer cells in situ and indicates the possibility that extracellular proteins and/or embryonic mesenchymal fibroblasts may represent a fertile subject for study of new anti-cancer treatments.

Echogenic Liposomes For Nitric Oxide Delivery And Breast Cancer Treatment, Soo Yeon Lee Female

Dissertations & Theses (Open Access)

Liposomes, also known as nontoxic, biodegradable, and non-immunogenic therapeutic delivery vehicles, have been proposed as a carrier for drugs and antitumor agents in cancer chemotherapy. Echogenic liposomes (ELIP) have the potential to entrap air or bioactive gas to enhance acoustic reflectivity in ultrasound and are used as a contrast agent. The innovative part of this study is based on a novel concept to encapsulate nitric oxide (NO) gas into ELIP, deliver it to breast cancer cells, and control its release via direct ultrasound exposure. Studies on the effect of NO in tumor biology have shown that a high levels of …

Differential Control Of Tgm2 Expression By Oestrogen Receptor/Serms., Damian Lally

Masters

Breast cancer is a malignancy of the epithelial cells comprising the mammary gland. As the ER is necessary for the growth of pproximately 70% of breast cancers, pharmaceutical efforts have focused on uncovering modulators of the ERα such as antiestrogens and Selective Oestrogen Receptor Modulator (SERMs). SERMs differ from pure ER antagonists in their capacity to display tissue-selective and C promoter dependent agonist-antagonist activities. Tamoxifen (TAM) is a SERM that is used in the treatment of hormonally responsive breast cancer. TAM is the most commonly used treatment for patients with ERα positive breast cancer. In this study we examined the …

The Functional Significance Of Nuclear Receptor Acetylation., Vladimir M. Popov, Chenguang Wang, L . Andrew Shirley, Anne Rosenberg, Shengwen Li, Marja Nevalainen, Maofu Fu, Richard G. Pestell

Department of Cancer Biology Faculty Papers

The endocrine signaling governing nuclear receptor (NR) function has been known for several decades to play a crucial role in the onset and progression of several tumor types. Notably among these are the estrogen receptor (ER) in breast cancer and androgen receptor (AR) in prostate cancer. Other nuclear receptors may be involved in cancer progression including the peroxisome-proliferator activating receptor gamma (PPARgamma), which has been implicated in breast, thyroid, and colon cancers. These NR are phylogenetically conserved modular transcriptional regulators, which like histones, undergo post-translational modification by acetylation, phosphorylation and ubiquitination. Importantly, the transcriptional activity of the receptors is governed …
