Oncostatin M Promotes Breast Cancer Metastasis: Increased Expression Of Pro-Angiogenic Factors, Inflammatory Cytokine Expression, And Circulating Tumor Cell Numbers, Ken Tawara
Boise State University Theses and Dissertations
Breast cancer is the most diagnosed cancer type in women and its resultant mortality is second only to lung cancer worldwide. While breast cancer is known to have many risk factors, inflammation remains an unquantifiable risk, and it can arise from obesity, depression, poor health, autoimmune diseases, and other conditions that cause systemic chronic inflammation. Chronic inflammation is gaining recognition for its role in cancer development, the potentiation of a metastatic phenotype in cancer cells, and decreased survival in breast cancer patients. In particular, inflammatory cytokines in the interleukin-6 (IL-6) family have been shown to promote an epithelial-mesenchymal transition (EMT), …
The P53 Independent Functions Of Estrogen-Activated Mdm2 In Cell Signaling And Mammary Architecture, Nandini Kundu
The P53 Independent Functions Of Estrogen-Activated Mdm2 In Cell Signaling And Mammary Architecture, Nandini Kundu
Dissertations, Theses, and Capstone Projects
Estrogen receptor positive (ER+) breast cancers often have MDM2 overexpression indicating a critical role for MDM2 in breast cancer tumorigenesis. The cancer genome atlas (TCGA) found that increased MDM2 expression is one of the four pathways that correlate with all breast cancer subtypes. MDM2 is mainly known as the negative regulator of wild type p53. However, aggressive breast cancers often have MDM2 overexpression and mutant p53 (mtp53). We previously reported that MDM2 provides an estrogen-mediated proliferative advantage to MCF-7 breast cancer cells (ER+, MDM2 overexpression, wild type p53), independent of wild type p53 in both 2D and 3D culture conditions. …
The Role Of Ehd2 In Triple-Negative Breast Cancer Tumorigenesis And Progression, Timothy A. Bielecki
The Role Of Ehd2 In Triple-Negative Breast Cancer Tumorigenesis And Progression, Timothy A. Bielecki
Theses & Dissertations
Triple-negative breast cancer (TNBC) comprises 10%-15% of all breast cancer cases, yet is clinically challenging due to lack of targeted therapies which leads to higher mortality. Molecular subtyping has identified the most aggressive subclasses of breast cancer to be enriched in components of caveolae. While caveolae have been linked to many biological processes, their precise role in TNBC is still poorly understood. EHD2, a member of the C-terminal EPS15-Homology Domain-containing (EHD) protein family, has emerged as a new regulator of caveolae dynamics and is essential to maintain a stable membrane pool of caveolae. Studies in model cells demonstrate that caveolae …
Targeting Autophagy To Improve Efficacy Of Cdk4/6 Inhibition In Breast Cancer, Smruthi Vijayaraghavan
Targeting Autophagy To Improve Efficacy Of Cdk4/6 Inhibition In Breast Cancer, Smruthi Vijayaraghavan
Dissertations & Theses (Open Access)
Deregulation of the cell cycle machinery is a hallmark of cancer, leading to aberrant proliferation and tumorigenesis. The crucial role of the CDK4/6-Cyclin D pathway has led to the development and FDA approval (palbociclib, ribociclib) of CDK4/6 inhibitors for the treatment of advanced estrogen receptor positive breast cancer. However, three major clinical challenges remain: i) adverse events leading to discontinuation of therapy and ii) lack of reliable biomarkers to identify responsive patients and iii) acquired resistance to CDK4/6 inhibitors. Previous in vitro studies have shown that palbociclib mediated CDK4/6 inhibition induces G1 arrest and senescence in ER+ breast cancer cells, …
Mt1-Mmp Mediates The Migratory And Tumourigenic Potential Of Breast Cancer Cells Via Non-Proteolytic Mechanisms, Mario Cepeda
Mt1-Mmp Mediates The Migratory And Tumourigenic Potential Of Breast Cancer Cells Via Non-Proteolytic Mechanisms, Mario Cepeda
Electronic Thesis and Dissertation Repository
Membrane Type-1 Matrix Metalloproteinase (MT1-MMP) is a multifunctional protease that affects cell function via proteolytic and non-proteolytic mechanisms such as promoting degradation of the extracellular matrix (ECM) or augmentation of cell migration and viability, respectively. MT1-MMP has been implicated in metastatic progression ostensibly due to its ability to degrade ECM components and to allow migration of cells through the basement membrane. Despite in vitro studies demonstrating this principle, this knowledge has not translated into the use of MMP inhibitors (MMPi) that inhibit substrate catalysis as effective cancer therapeutics, or been corroborated by evidence of in vivo ECM degradation mediated by …
Understanding The Genotoxicity Of Silver Nanoparticles And The Chemoprevention Of Pomegranate Extract, Sameera Nallanthighal
Understanding The Genotoxicity Of Silver Nanoparticles And The Chemoprevention Of Pomegranate Extract, Sameera Nallanthighal
Legacy Theses & Dissertations (2009 - 2024)
The use of silver nanoparticles (AgNPs) in a wide variety of consumer products (i.e. toothpastes, food containers, dietary supplements and garments) for their antimicrobial properties can lead to potential oral exposure in humans. To enhance their stability, AgNPs are coated with capping agents such as citrate and polyvinylpyrrolidone (PVP). Despite the lack of significant general toxicity based on hematology, blood chemistry and histology evaluations, the potential genotoxic effects of AgNPs cannot be ruled out and have to be addressed. Studies examining the genotoxic risks of AgNPs are needed because genotoxicity is a strong indicator of cancer risk. Here we examined …
