The Role Of Tumor Suppressor Co-Chaperone Chip/Stub1 In Erbb2-Mediated Oncogenesis, Haitao Luan
The Role Of Tumor Suppressor Co-Chaperone Chip/Stub1 In Erbb2-Mediated Oncogenesis, Haitao Luan
Theses & Dissertations
The epidermal growth factor receptor (EGFR) family member ErbB2 (Her2) is overexpressed in 20 -30% of invasive breast cancers and this overexpression correlates with poor prognosis and shorter overall as well as disease-free survival. Aberrant expression of ErbB2 through gene amplification, transcriptional deregulation and/or altered endocytic trafficking results in overexpression of ErbB2 at the plasma membrane and biases ErbB2 from primarily ligand-driven hetero-dimerization under normal expression conditions to increased ligand-independent homo-dimer and hetero-dimer formation and consequent activation. C-terminus of HSC70-Inteeracting protein (CHIP)/STIP1-homologous U-Box containing protein 1 (STUB1) is an HSP90/HSC70 interacting negative co-chaperone known to promote ubiquitination and degradation of …
The Ras Effector Nore1a Forms A Tumor Suppressor Complex With Brca1., Nicholas C Nelson
The Ras Effector Nore1a Forms A Tumor Suppressor Complex With Brca1., Nicholas C Nelson
Electronic Theses and Dissertations
Ras proteins function as molecular signaling switches that can stimulate multiple mitogenic pathways in response to extracellular signaling. Oncogenic activation of Ras by structural mutation is a highly transforming event in ~1/3 of human cancers. However, aberrant Ras activation can also promote oncogene-induced senescence. This Ras-induced irreversible growth arrest is a physiological process that acts as a barrier to malignancy. The mechanisms by which Ras drives senescence and how this process is bypassed during Ras-driven transformation remains poorly understood.
Although mutations in the RAS gene are extremely rare in human breast cancer, the Ras signaling pathway is constitutively activated in …
Breast Cancer Rehabilitation: Clinical Examination And Outcomes Assessment, Nicole L. Stout, Shana Harrington, Lucinda Pfalzer, Mary Insana Fisher
Breast Cancer Rehabilitation: Clinical Examination And Outcomes Assessment, Nicole L. Stout, Shana Harrington, Lucinda Pfalzer, Mary Insana Fisher
Mary Insana Fisher
Breast cancer is the most commonly diagnosed cancer in women in the United States. The treatment for breast cancer occurs along a protracted time period and includes many different disease treatment modalities. These treatments carry with them a large number of adverse effects that negatively impact function in both the short term and long term. It is necessary for rehabilitation providers to interface with patients being treated for breast cancer throughout the continuum of care so that interval assessments can be conducted to identify emerging impairments and alleviate disability. To achieve this, the rehabilitation provider must have an understanding of …
The Investigation Of Rhodiola Crenulata Root Extract Effects On Obesity Associated Inflammation And The Antineoplastic Mechanism In Breast Cancer Cells, Lotfi M. Bassa
Doctoral Dissertations
Obesity and breast cancer are two disease models that directly affect the United States population, as more than 35% of the adult population is obese [8], and more than 200,000 new cases of breast cancer are diagnosed in the United States per year [34]. Several diseases are associated with obesity including, cardiovascular disease, insulin resistance, increased inflammation and increased cancer risk [9,10]. Therefore it essential to understand the risks associated with obesity as well as to investigate possible preventive and/or therapeutic treatment strategies. Rhodiola crenulata is a Tibetan plant that has been used in Eastern traditional medicine to relieve depression, …

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. …

The Role Of Connexins And Pannexins In Mammary Gland Development And Tumorigenesis, Michael K. G. Stewart
The Role Of Connexins And Pannexins In Mammary Gland Development And Tumorigenesis, Michael K. G. Stewart
Electronic Thesis and Dissertation Repository
The identification of key regulators of breast cancer onset and progression is critical for the development of targeted therapies. Connexins and pannexins are characterized by their ability to form large-pore channels and are frequently dysregulated in cancer. However, their role in breast cancer progression remains poorly understood due to a lack of in vivo models capable of assessing the proposed and opposing roles of connexins and pannexins as both tumor suppressors and/or facilitators in multiple stages of the disease. Using 2 previously uncharacterized genetically-modified mice, connexin43 (Cx43) and connexin26 (Cx26) were evaluated for their role in normal mammary gland development …
Prophylactic Cranial Irradiation Reduces The Incidence Of Brain Metastasis In A Mouse Model Of Metastatic Breast Cancer, Daniel L. Smith
Prophylactic Cranial Irradiation Reduces The Incidence Of Brain Metastasis In A Mouse Model Of Metastatic Breast Cancer, Daniel L. Smith
Dissertations & Theses (Open Access)
Prophylactic cranial irradiation (PCI) is a preventative whole-brain irradiation technique used to reduce the incidence of brain metastasis and improve overall survival in select patients with small cell lung cancer and acute lymphoblastic leukemia. A population of breast cancer patients – stage IV, HER2+ or triple-negative – has emerged as having a high risk of developing brain metastases. Because only 10-20% of breast cancer patients diagnosed with brain metastases survive longer than one year, in this high-risk population the benefit of PCI – potential for reduced incidence of brain metastasis and improved overall survival – may outweigh the risks – …
A Comparison Of Upper Extremity Function Between Female Breast Cancer Survivors And Healthy Controls: Typical Self-Report Of Function, Motion, Strength, And Muscular Endurance, Mary Insana Fisher
A Comparison Of Upper Extremity Function Between Female Breast Cancer Survivors And Healthy Controls: Typical Self-Report Of Function, Motion, Strength, And Muscular Endurance, Mary Insana Fisher
Mary Insana Fisher
Many women who have experienced breast cancer (BC) report continued impairments in upper extremity (UE) function beyond the time required for normal healing after surgical treatment. Most research supporting this has not made comparisons between survivors of breast cancer (BCS) to a sample of healthy women. This lack of comparison to a healthy cohort prevents an understanding of whether continued deficits in UE function are due to normal aging or the BC treatment. The purpose of this research was to compare quality of life (QOL) and UE function among long term breast cancer survivors and similar aged women without cancer. …

Mary Insana Fisher
Lymphedema affects 3–58% of survivors of breast cancer and can result in upper extremity impairments. Exercise can be beneficial in managing lymphedema. Yoga practice has been minimally studied for its effects on breast cancer related lymphedema (BCRL). The purpose of this study was to determine the effect of yoga on arm volume, quality of life (QOL), self-reported arm function, and hand grip strength in women with BCRL. Six women with BCRL participated in modified Hatha yoga 3×/week for 8 weeks. Compression sleeves were worn during yoga sessions. Arm volume, QOL, self-reported arm function, and hand grip strength were measured at …
The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell
The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell
Mary Insana Fisher
Breast cancer is one of the most frequently diagnosed cancers among women. Breast cancer treatments often negatively impact the function of the arm, and quality of life and upper extremity function does not always return to a prediagnosis level. Survivors of breast cancer may also experience feelings of diminished self-efficacy related to functional deficits resulting from their physical limitations. The International Classification of Functioning (ICF) provides a framework for rehabilitation practitioners to address physical and psychological impairments, activity limitations, and participation restrictions. Patient outcomes may be improved by fostering self-efficacy through empowerment. This paper explores how the ICF model and …
Nitric Oxide-Releasing Aspirin Suppresses Nf-Κb Signaling In Estrogen Receptor Negative Breast Cancer Cells In Vitro And In Vivo, Niharika Nath, Mitali Chattopadhyay, Deborah B. Rodes, Anna Nazarenko, Ravinder Kodela, Khosrow Kashfi
Nitric Oxide-Releasing Aspirin Suppresses Nf-Κb Signaling In Estrogen Receptor Negative Breast Cancer Cells In Vitro And In Vivo, Niharika Nath, Mitali Chattopadhyay, Deborah B. Rodes, Anna Nazarenko, Ravinder Kodela, Khosrow Kashfi
Publications and Research
Estrogen receptor negative (ER(−)) breast cancer is aggressive, responds poorly to current treatments and has a poor prognosis. The NF-κB signaling pathway is implicated in ER(−) tumorigenesis. Aspirin (ASA) is chemopreventive against ER(+) but not for ER(−) breast cancers. Nitric oxide-releasing aspirin (NO-ASA) is a safer ASA where ASA is linked to an NO-releasing moiety through a spacer. In vitro, we investigated anti-proliferation effects of NO-ASA (para- and meta-isomers) against ER(−) breast cancer cells MDA-MB-231 and SK-BR-23, effects on NF-κB signaling, and reactive oxygen species by standard techniques. In vivo, effects of NO-ASA were evaluated in a mouse xenograft model …
Numerical Simulation Of Terahertz Wave Interaction With Breast Cancer Tumor Tissue Sections, Abayomi Omotola Omolewu
Numerical Simulation Of Terahertz Wave Interaction With Breast Cancer Tumor Tissue Sections, Abayomi Omotola Omolewu
Graduate Theses and Dissertations
This thesis presents numerical simulation of terahertz (THz) wave interaction with breast cancer tumor tissue sections. The obtained results are expressed in THz images of heterogeneous material that mimics the excised breast cancer tissue sections. The finite-element software package ANSYS High Frequency Structural Simulator (HFSS) was used in this work. HFSS is a full wave frequency domain three-dimensional (3D) electromagnetic simulation package. In this work, four breast cancer tissue models based on pathology images were simulated and images of the models were obtained at 1 THz. An incident Gaussian beam was raster scanned over tissue model configurations and the reflected …
The Lung Microenvironment Influences The Metastatic Behaviour Of Breast Cancer Cells In An Innovative 3d Ex Vivo Pulmonary Metastasis Model, Matt M. Piaseczny
The Lung Microenvironment Influences The Metastatic Behaviour Of Breast Cancer Cells In An Innovative 3d Ex Vivo Pulmonary Metastasis Model, Matt M. Piaseczny
Electronic Thesis and Dissertation Repository
Lung metastasis remains a leading cause of death in breast cancer patients. This study established an innovative 3D ex vivo pulmonary metastasis assay (PuMA) to test the hypothesis that the lung microenvironment promotes metastatic behaviour of whole population and stem-like ALDHhiCD44+ breast cancer cells. Following in vivo delivery of breast cancer cells to mice, lungs were excised, maintained in culture and imaged to observe breast cancer growth over time. We observed metastatic progression of breast cancer cells in the PuMA, most notably of ALDHhiCD44+ cells which progressed rapidly from single cells to multicellular colonies …

The Cancer Genome Atlas (Tcga): Breast And Ovarian Cancers, Laura Ann Riccio
Senior Honors Projects
The field of genomics originated in the 1970’s starting with the sequencing of small organisms’ genomes such as the bacterium, Haemophilus influenzae, and the yeast, Saccharomyces cerevisiae. A genome is the complete ordered sequence of DNA bases (A, C, G, and T) comprising all of the protein- and RNA-coding genes, as well as all of the regulatory sequences necessary for the construction of an organism. Over time, scientists sequenced the genomes of larger and more complex organisms, eventually leading to the sequencing of the human genome. The Human Genome Project (HGP) was initiated in 1990 and took over ten …
Stat6 Mediates Interleukin-4 Growth Inhibition In Human Breast Cancer Cells, Jennifer L. Gooch, B. Christy, D. Yee
Stat6 Mediates Interleukin-4 Growth Inhibition In Human Breast Cancer Cells, Jennifer L. Gooch, B. Christy, D. Yee
Jennifer L. Gooch
In addition to acting as a hematopoietic growth factor, interleukin-4 (IL-4) inhibits growth of some transformed cells in vitro and in vivo. In this study, we show that insulin receptor substrate (IRS)-1, IRS-2, and signal transducer and activator of transcription 6 (STAT6) are phosphorylated following IL-4 treatment in MCF-7 breast cancer cells. STAT6 DNA binding is enhanced by IL-4 treatment. STAT6 activation occurs even after IRS-1 depletion, suggesting the two pathways are independent. To examine the role of STAT6 in IL-4-mediated growth inhibition and apoptosis, a full-length STAT6 cDNA was transfected into MCF-7 cells. Transient overexpression of STAT6 resulted in …

Integrative Analysis Of Survival-Associated Gene Sets In Breast Cancer, Frederick S. Varn, Matthew H. Ung, Shao Ke Lou, Chao Cheng
Dartmouth Scholarship
Patient gene expression information has recently become a clinical feature used to evaluate breast cancer prognosis. The emergence of prognostic gene sets that take advantage of these data has led to a rich library of information that can be used to characterize the molecular nature of a patient’s cancer. Identifying robust gene sets that are consistently predictive of a patient’s clinical outcome has become one of the main challenges in the field. We inputted our previously established BASE algorithm with patient gene expression data and gene sets from MSigDB to develop the gene set activity score (GSAS), a metric that …

Proteasome Inhibition As A Potential Anti-Breast Cancer Therapy: Mechanisms Of Action And Resistance-Reversing Strategies, Rahul Rajesinh Deshmukh
Wayne State University Dissertations
AMPK activation and Ubiquitin Proteasome System (UPS) inhibition have gained great attention as therapeutic strategies for the treatment of certain types of cancers. While AMPK serves as a master regulator of cellular metabolism, UPS regulates protein homeostasis. Although the crosstalk between them is suggested, the relationship between these two important pathways is not very clear. We observed that proteasome inhibition leads to AMPK activation in human breast cancer cells. We report that a variety of proteasome inhibitors activate AMPK in all of the tested cancer cell lines. Our data using Liver Kinase B1 (LKB1)-deficient cancer cells suggests that proteasome inhibitor-induced …

The Role Of P62/Imp2 In Breast Cancer Progression, Yang Li
The Role Of P62/Imp2 In Breast Cancer Progression, Yang Li
Open Access Theses & Dissertations
Breast cancer is one of the most common types of cancer in women. In most patients with breast cancer, it is not the primary tumor that leads to death, but rather metastatic tumors. Once breast cancer spreads to other organs in the body, the disease becomes almost incurable. It is estimated that about 20% to 50% of patients diagnosed with primary breast cancer will develop metastatic disease. Considering this, it is important to understand the molecular and cellular mechanisms behind metastatic breast cancer and to identify new proteins that regulate the metastatic process. These proteins may be used as targets …
Effect Of Adjuvant And Neoadjuvant Anti-Telomerase With Anthracycline Based Chemotherapy On Triple Negative Breast Cancer Cells, Luke T. Pardy
Effect Of Adjuvant And Neoadjuvant Anti-Telomerase With Anthracycline Based Chemotherapy On Triple Negative Breast Cancer Cells, Luke T. Pardy
Student Summer Scholars Manuscripts
Breast cancer is the second leading cause of cancer related death in women in the US. In addition, 20% of all breast cancer cases in the U.S. are from the subtype known as Triple-Negative Breast Cancer (TNBC), which is the most aggressive and invasive form of the disease. This type of breast cancer has the worst prognosis, a decreased survival rate, and no targeted therapy. Over the decades, interest in pre- (Neoadjuvant) and post- (Adjuvant) chemotherapy treatments, in the management of TNBC has increased. Therefore, we evaluated the Adjuvant and Neoadjuvant effects of anti-telomerases (BIBR 1532 and GV6) with anthracycline-based …
Vitamin D Regulates Metabolic Gene Expression, Glutamate And Glutamine Utilization, And Mitochondrial Function In Human Mammary Epithelial Cells, Sarah Beaudin
Legacy Theses & Dissertations (2009 - 2024)
Exposure to 1,25-Dihydroxyvitamin D (1,25D) decreases proliferation and induces differentiation in telomerase-immortalized human mammary epithelial (hTERT-HME1) cells. The studies described here addressed the mechanisms by which these effects are exerted. Microarray experiments were used to identify a subset of metabolic genes and pathways that are altered by 1,25D. In particular, genes involved in glutamate and glutamine utilization, including SLC1A1 and GLUL, were studied. Interestingly, qPCR analysis in a panel of six cell lines, representing either normal epithelial tissue or breast cancer, demonstrated diverse gene expression responses to 1,25D. In an isogenic model of mammary cell transformation, 1,25D altered gene expression …
