The Effect Of Yamanaka Factors On The Metastatic Potential Of Breast Cancer Cells, 2024 University of Northern Colorado
The Effect Of Yamanaka Factors On The Metastatic Potential Of Breast Cancer Cells, Riley Mendonca
Undergraduate Honors Theses
The mortality associated with cancer is most commonly a result of it spreading to other tissues and organs in a process known as metastasis. For carcinomas to do this they must first break through the basement membrane containing them to interact with the stroma. This is known as an epithelial-mesenchymal transition and occurs when carcinomas suppress their original epithelial qualities in order to adopt more mesenchymal ones. This involves cancers dedifferentiating from their original cell type to lose the specialized features that distinguished them and where they came from. As cancers become more invasive, this dedifferentiation becomes more pronounced. Recent …

Acute Myeloid Leukemia (AML) and Multiple Myeloma (MM) are hematologic malignancies that originate in the bone marrow and account for approximately 1.3% and 2% of cancer cases, respectively. AML is characterized by an accumulation of myeloblasts, or immature myeloid cells, that have the potential to spread to the peripheral blood. There is an uncontrolled proliferation of plasma cells in the bone marrow in MM. While the current treatment options for both AML and MM show promise in achieving initial remission, it is unfortunately common for patients to experience relapse and develop drug resistance. There is a theory that relapse and …

Exploring The Role Of Il-1Β/Il-1r In The Pathogenesis Of K-Ras Mutant Lung Cancer, Avantika Krishna
Dissertations & Theses (Open Access)
As the leading cause of cancer-related deaths worldwide, the development of targeted therapeutics to treat lung cancer remains crucial. Non-small cell lung cancer (NSCLC), the most common histological subtype predominantly comprises lung adenocarcinoma with driver mutations in the K-ras oncogene (KM-LUAD). KM-LUAD progression partly occurs through activation of the NF-κB pathway initiating an inflammatory response and creating a pro-tumor microenvironment. Notably, the pro-inflammatory cytokine IL-1β a potent activator and product of the NF-κB pathway is elevated in the lungs and sera of KM-LUAD patients. We have shown that IL-1β blockade promotes an anti-tumor immune phenotype in a mouse model of …

Dissertations & Theses (Open Access)
High-risk type human papillomaviruses (HPV) are associated with genital and oral cancers, and the incidence of HPV+ head and neck squamous cell cancers is fast increasing worldwide. Survival rates for patients with locally advanced disease are poor and variable after standard of care (SOC) treatment. Identifying the antitumor host immune mediators important for treatment response and designing strategies to promote them are essential for improving clinical outcome. The natural killer (NK) cells are a critical component for antitumor innate effector immunity. Among the multitude of activation and inhibitory receptors on immune cells, HLA-DR is recognized as an important activation marker …
Mast Cells In Mammary Carcinoma, 2024 University of Northern Colorado
Mast Cells In Mammary Carcinoma, Alexandria M. Ashbaugh
Undergraduate Honors Theses
Breast cancer (BC) is an aggressive disease that takes the lives of thousands of women every year. Although knowledge and treatment of this disease have improved over the years, much is still to be discovered about BC. One area of expertise that we are currently trying to learn more information about is the mast cell (MC) and its role in BC growth and development. The MC is an immune system component discovered in tumors' extracellular matrix (ECM). As a tumor grows within body tissues, the tumor recruits the MC from surrounding connective tissues to the tumor, using signaling cytokines such …

Mcl-1 Mediates Intrinsic Resistance To Raf Inhibitors In Mutant Braf Papillary Thyroid Carcinoma, 2024 Thomas Jefferson University
Mcl-1 Mediates Intrinsic Resistance To Raf Inhibitors In Mutant Braf Papillary Thyroid Carcinoma, Maria Cavallo, Jacob Yo, Kayla Gallant, Camille Cunanan, Amirali Amirfallah, Marzieh Daniali, Alyssa Sanders, Andrew Aplin, Edmund Pribitkin, Edward Hartsough
Kimmel Cancer Center Faculty Papers
Papillary thyroid carcinoma (PTC) is the most frequent form of thyroid cancer. PTC commonly presents with mutations of the serine/threonine kinase BRAF (BRAFV600E), which drive ERK1/2 pathway activation to support growth and suppress apoptosis. PTC patients often undergo surgical resection; however, since the average age of PTC patients is under 50, adverse effects associated with prolonged maintenance therapy following total thyroidectomy are a concern. The development of mutant-selective BRAF inhibitors (BRAFi), like vemurafenib, has been efficacious in patients with metastatic melanoma, but the response rate is low for mutant BRAF PTC patients. Here, we assay the therapeutic response …

Killing Cancer: Manipulating Hydrophobic Vanadium Complexes To Improve Anti-Cancer Activity, Levi Ausherman, Debbie C. Crans, Peter A. Lay, Maggi Braasch-Turi
SACAD: John Heinrichs Scholarly and Creative Activity Days
Hydrophobic vanadium complexes have recently shown improved anti-cancer activities compared to cisplatin. The hydrophobicity and anti-proliferative activity of [VO(Hshed)(dtb)] ([Hshed= N-(salicylideneaminato)-N’-(2-hydroxyethyl)-1,2-ethanediamine and dtb= 3,5-di(tert-butyl)catechol)]) have inspired the development of a library of hydrophobic vanadium complexes. Increasing the steric bulk of the catechol ligand has been shown to have a direct impact on hydrophobicity and anti-proliferative activities. Currently at Fort Hays State University, the Braasch-Turi group is synthesizing VO(HSHED)(dtb) to build up material to support the chemical analysis and biological assay performed by our collaborators at Colorado State University and the University of Sydney, Australia, respectively. In the future, we plan …
Deciphering The Functional Connections Between The Nuclear Paraspeckle And Rad51 Homologous Recombination Proteins Using A Yeast Protein Interaction System, 2024 University of South Carolina - Columbia
Deciphering The Functional Connections Between The Nuclear Paraspeckle And Rad51 Homologous Recombination Proteins Using A Yeast Protein Interaction System, Eric J. Nutz
Senior Theses
Homologous recombination (HR) is a repair pathway for DNA double-stranded breaks. Mutations in HR genes contribute to genomic instability and increase the prevalence of cancer. Exploiting HR deficiency in tumor cells has led to improved synthetic lethality outcomes. RAD51 paralogue protein complexes are known to be involved with HR. Proteomic analysis of RAD51 paralogues reveals a connection to the nuclear paraspeckle. A paraspeckle is a little-known, specialized organelle found in the interchromatin space of the nucleus in mammalian cells. Its three central protein components include SFPQ, NONO, and PSPC1. RAD51D is an HR protein shown previously to interact with SFPQ …

Undergraduate Research Symposium
Triple negative breast cancer (TNBC) is one of the most aggressive forms of breast cancer, and disproportionately affects African American women. TNBC cells lack the common hormone receptors that many pre-existing cancer treatments target. Fortunately, metal-based complexes with thiosemicarbazone ligands have gained significant attention for their potential as anti-cancer agents. Cobalt(III) complex ([Co(phen)2(MeATSC)](NO3)3•1.5H2O•C2H5OH]) and Copper(II) complex ([Cu(acetylethTSC)Cl]Cl•0.25C2H5OH) specifically have properties of high toxicity, which can contribute to decreased cancer cell activity. The effects of these complexes are currently being investigated on cancerous and non-cancerous breast cell lines. The cytotoxic effect of the cobalt(lll) complex and the copper(ll) complex was analyzed …
