Assessing The Anticipated Needs Of Transgender Patients In Cancer Genetic Counseling, Jacqueline Baquet
Assessing The Anticipated Needs Of Transgender Patients In Cancer Genetic Counseling, Jacqueline Baquet
Theses and Dissertations
Most cancers are sporadic, but 5-10% of all cancer is hereditary, or caused by a heritable genetic mutation. A patient’s medical history, family history, genetic test results, intact organs (e.g., ovaries) at an increased risk for developing cancer, and the availability and accessibility of interventions are used to make recommendations for cancer-risk management. In addition to basic medical care, transgender patients have healthcare needs that differ from those of cisgender patients such as expert care related to using hormones or having gender-affirming surgery, as well as unique mental health concerns. Transgender individuals may also experience a greater number of barriers …
Exploration Of Patient Communication Preference Regarding Reclassified Genetic Test Results, Cooper Nicole Hall
Exploration Of Patient Communication Preference Regarding Reclassified Genetic Test Results, Cooper Nicole Hall
Theses and Dissertations
Genetic testing is becoming increasingly used to detect individuals who are predisposed to developing cancer. If genetic testing identifies a variant in an individual’s DNA, the testing laboratory uses available data to classify the variant as either disease-causing or benign. When limited data is available regarding a variant’s pathogenicity and the risk of cancer for an individual is not clear, the variant is classified as a “variant of uncertain significance” (VUS). If new data is discovered, the VUS may be reclassified. There is a gap in current literature regarding desired communication for a reclassified genetic test result. There are no …
Biophysical Characterization Of The Par-4 Tumor Suppressor: Evidence Of Structure Outside The Coiled Coil Domain And Interactions With Platinum Chemotherapeutics, Andrea Megan Clark
Biophysical Characterization Of The Par-4 Tumor Suppressor: Evidence Of Structure Outside The Coiled Coil Domain And Interactions With Platinum Chemotherapeutics, Andrea Megan Clark
Chemistry & Biochemistry Theses & Dissertations
Prostate apoptosis response-4 (Par-4) is an apoptosis-inducing tumor suppressor protein. Full-length Par-4 has previously been shown to be a predominantly intrinsically disordered protein (IDP) under neutral conditions, with significant regular secondary structure evident only within the C-terminal coiled coil domain. However, IDPs can gain ordered structure through the process of induced folding, which often occurs under non-neutral conditions. Previous work has shown that the Par-4 leucine zipper, which is a subset of the C-terminal coiled coil domain, is disordered under neutral conditions, but forms a dimeric coiled coil at acidic pH. Increase in ionic strength was also shown to increase …
Examining The Mechanistic Roles Of Integrin Alpha-6 In Cancer Metastasis., Chase T. Clark
Examining The Mechanistic Roles Of Integrin Alpha-6 In Cancer Metastasis., Chase T. Clark
Honors College Theses
Metastasis- the spread of cancer cells from the primary tumor to the surrounding tissues- is responsible for 90% of cancer deaths. Integrin alpha-6 (ITGA6) is a specific transmembrane cell surface protein that functions in cell surface adhesion and signaling. ITGA6 is upregulated in many types of cancers and promotes the migration and invasion of cancer cells to surrounding tissues. It is my objective to determine the mechanism through which ITGA6 facilitates the migration of cancer cells through the extracellular matrix (ECM). These experiments helped to establish the role of ITGA6 in tumor development and provide focus for possible chemotherapeutic treatment. …
Metabolic Reprogramming By Dna Tumour Viruses, Martin Prusinkiewicz
Metabolic Reprogramming By Dna Tumour Viruses, Martin Prusinkiewicz
Electronic Thesis and Dissertation Repository
Viruses are the etiological agents of approximately 12% of human cancers. However, only a subset of viral infections eventually progress to cancer. As obligate intracellular parasites, viruses create a host-cell environment that is amenable to virus replication. These changes to host-cell processes during infection are enacted by virally-encoded proteins that act as molecular hubs. When these processes intersect with pathways that encourage the development of cancer, such as the p53 tumour suppressor pathway, these virally-encoded molecular hub proteins function as viral oncoproteins. One major requirement of both virus infected cells and rapidly growing cancer cells is an altered metabolism that …
Anti-Cancer Effects By Interleukin 24, Xuelin Zhong
Anti-Cancer Effects By Interleukin 24, Xuelin Zhong
Dissertations, Theses, and Capstone Projects
Cancers develop as some cells acquire the ability, either by exogenous stimulation or by spontaneous mutation, to keep growing despite normal restraints. Up-regulating translation of oncogenes involved in cell proliferation and tumor development and down-regulating translation of tumor-suppressors that normally suppress tumor development are two most common mechanisms by which cancers develop. Therefore, it is crucial to study how these proteins get either up-regulated or down-regulated at translational level.
The eukaryotic translation initiation factor, which is composed of subunits such as eIF4A, eIF4G and eIF4E, is one of the key factors that contribute to efficient translation initiation. Interleukin 24 (IL-24), …
A New Mathematical Theory For The Dynamics Of Large Tumor Populations, A Potential Mechanism For Cancer Dormancy & Recurrence And Experimental Observation Of Melanoma Progression In Zebrafish, Adeyinka A. Lesi
Dissertations and Theses
Cancer, a family of over a hundred disease varieties, results in 600,000 deaths in the U.S. alone. Yet, improvements in imaging technology to detect disease earlier, pharmaceutical developments to shrink or eliminate tumors, and modeling of biological interactions to guide treatment have prevented millions of deaths. Cancer patients with initially similar disease can experience vastly different outcomes, including sustained recovery, refractory disease or, remarkably, recurrence years after apparently successful treatment. The current understanding of such recurrences is that they depend on the random occurrence of critical mutations. Clearly, these biological changes appear to be sufficient for recurrence, but are they …
Understanding The Epigenetic Role Of 8-Oxoguanine And Ogg1 In Non-Small Cell Lung Cancer, Kyrellos Ibrahim
Understanding The Epigenetic Role Of 8-Oxoguanine And Ogg1 In Non-Small Cell Lung Cancer, Kyrellos Ibrahim
CMC Senior Theses
Oxidative damage to the genome can form 8-oxoguanine (oxoG), a premutagenic lesion suggested to play an epigenetic role in the regulation of various cellular pathways. Alongside oxoG in this regulation is the 8-oxoguanine DNA glycosylase (OGG1), which primarily functions to repair oxoG damage via base excision repair, but is also implicated in recruiting NFκB and impacting gene expression associated with cancer growth. This proposal aims to build genome-wide maps of oxoG occupancy, and indirectly OGG1 localization, in healthy lung cells and in non-small cell lung cancer adenocarcinoma cells in order to identify regulatory regions in the genome at which oxoG …
Association Between Plasma Genistein And Health-Related Quality Of Life In Breast Cancer Survivors, Tran Pham
Association Between Plasma Genistein And Health-Related Quality Of Life In Breast Cancer Survivors, Tran Pham
Honors Undergraduate Theses
According to the American Cancer Society, breast cancer is the most commonly diagnosed cancer and is the second leading cause of cancer death in American women. Breast cancer screenings and improvement in treatments have resulted in the rising number of survivors in the recent decade. This urged the need for post-diagnosis lifestyle changes to improve breast cancer patients' quality of life. Many studies found soy food, the primary dietary source of phytoestrogens, has a protective effect against breast cancer recurrence and mortality. Dietary phytoestrogens can be classified into two groups: isoflavones and lignans. Daidzein and genistein were identified as the …
Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant
Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant
Honors Theses
Laromustine is an experimental chemotherapeutic sulfonyl hydrazine prodrug shown in clinical trials to be effective against acute myeloid leukemia. The mechanism of action of laromustine involves interstrand crosslinking, via chloroethylation, and enzyme inhibition, caused by carbamoylation. The work described herein aims to investigate whether inhibition of the replication-dependent interstrand crosslink repair Fanconi Anemia pathway further sensitizes cells to laromustine. By measuring metabolic activity immediately after drug exposure, we find laromustine to be equally as cytotoxic towards Fanconi Anemia deficient and wild type cells. However, through clonogenic assays we show Fanconi Anemia mutations sensitize cells to laromustine’s anti-proliferative effect. Furthermore, we …

Browse all Theses and Dissertations
The functions of Ataxia telangiectasia and Rad-3 related protein (ATR) is very much important in a cell, as it is a DNA damage response protein, which plays an important role in cell division, DNA repair and apoptosis. This protein helps in proliferation in the actively DNA dividing normal cells and in cancer cells. The functions of ATR in a proliferating cell are well studied and known to involve regulation of replication fork and cell cycle progression after DNA damage. Whereas, in a non-replicating cell, the functions of ATR are not so well known. In the human body, most of the …
Cop9 Signalosome Component Csn-5 Promotes Accumulation And Function Of Stem Cell Regulators Fbf-1 And Fbf-2, Emily Osterli
Cop9 Signalosome Component Csn-5 Promotes Accumulation And Function Of Stem Cell Regulators Fbf-1 And Fbf-2, Emily Osterli
Graduate Student Theses, Dissertations, & Professional Papers
RNA-binding proteins FBF-1 and FBF-2 (FBFs) are required for stem cell maintenance in C. elegans, although the mechanisms by which FBFs protein levels are regulated remain unknown. Using a yeast two-hybrid screen, we identified an interaction between both FBFs and CSN-5, a component of the COP9 (constitutive photomorphogenesis 9) signalosome. This highly conserved COP9 complex can affect protein stability through a range of mechanisms including deneddylation, deubiquitination, and phosphorylation (Wolf et al., 2003). Mapping protein-protein interactions between FBFs and CSN-5 suggested that the MPN (Mpr1/Pad1 N-terminal) metalloprotease domain of CSN-5 interacts with the RNA-binding domain of FBFs at physiologically …

Investigating The Antitumor Effects Of A Dsrna-Nanoparticle Complex In An In Vitro Ovarian Cancer Model, Aaron Lewis
Theses and Dissertations (Comprehensive)
An estimated 1 in 70 women will be diagnosed with ovarian cancer in their lifetime. Despite advanced detection and treatment methods, it remains a silent killer with an expected survival rate of 50%. A developing method in cancer treatment is the use of compounds that stimulate the immune system to aid in the body's fight against the disease. This project focused on the use of the potent immune stimulant double-stranded RNA (dsRNA), commercially available as polyinosinic:polycytidylic acid, poly(I:C), to induce cytotoxicity in two ovarian cancer cell lines; SKOV-3 and OVCAR-3. Some challenges exist with the delivery of dsRNA due to …
Dna Polymerase Ε: Replication Error Prevention And Consequences Of A Cancer-Associated Mutation, Chelsea R. Bulock
Dna Polymerase Ε: Replication Error Prevention And Consequences Of A Cancer-Associated Mutation, Chelsea R. Bulock
Theses & Dissertations
Genome integrity is necessary to prevent mutations and disease. During eukaryotic DNA replication, DNA polymerases ε (Polε) and δ (Polδ) synthesize the leading and lagging strand, respectively. Polε and Polδ also have exonuclease activity that acts in series with post-replicative mismatch repair (MMR) to remove replication errors. Defects in proofreading and MMR lead to an increase in mutations and cause cancer in humans. This dissertation focuses on several unresolved issues involving the relationship between Polε and Polδ in replication error avoidance. First, despite an abundance of data supporting the one-strand-one-polymerase replication fork model, defects in the fidelity of Polε have …

Investigation Of Proliferation Suppressors In Genetic Fitness Screens, Walter Frank Lenoir Iv
Dissertations & Theses (Open Access)
Innovation of CRISPR gene-editing technology has provided scientists genome manipulation tools that allowed rapid advancement of scientific capabilities and thus improved our ability to systematically study mammalian genetic functional profiles. Genome-wide CRISPR knockout screens conducted in collections of human cell lines can knock out genes at multiple loci, and have provided new insights into functional roles for independent genes. This method has launched massive efforts in looking across genetic backgrounds for context specific genetic vulnerabilities within cancer. Much of the research effort thus far has been spent on optimizing phenotype distinctions between essential, genes required for cell fitness, and non-essential, …
Hpv Mediated Antagonism Of The Il-18 Proinflammatory Pathway In Head And Neck Cancer, Wyatt W. Anderson
Hpv Mediated Antagonism Of The Il-18 Proinflammatory Pathway In Head And Neck Cancer, Wyatt W. Anderson
Electronic Thesis and Dissertation Repository
In this thesis, I examined the effect of human papillomavirus (HPV) on the proinflammatory IL-18 cytokine pathway in head and neck cancers. I investigated the expression and methylation of genes associated with this pathway using The Cancer Genome Atlas (TCGA) data. In HPV+ cancers, IL18, CASP1, and AIM2 were downregulated, while IL18BP was upregulated compared to HPV- cancers and adjacent non-cancerous tissues, and IL18’s promoter was significantly more methylated. I compared HPV+ and HPV- head and neck cancer cell lines for expression of RNA and protein levels of IL-18 and IL-18BP by qPCR, western blot, and ELISA. IL-18 …

Inducing Dna-Mismatch Repair Deficiency In Tumours: A Strategy To Enhance Anti-Tumour Immunity, Mikal El-Hajjar
Electronic Thesis and Dissertation Repository
Immunotherapy has improved patient outcomes in advanced or metastatic settings across a number of cancers. Patients with tumours deficient in the DNA mismatch repair (DNA-MMR) pathway often show high response rates to immune checkpoint inhibitors (ICIs) with a rise in immune surveillance. However, little is known about the immune sensitization effects of inducing DNA- MMR-deficiency in low tumour mutational burden (TMB) cancers, such as ICI refractory neuroblastoma. In addition, the dynamic T-cell profile that results from such a DNA-MMR inactivation, and whether this may confer a therapeutic benefit, is poorly understood. Here we used CRISPR/CAS9 genome editing technology to knock …

Exploiting The Immunomodulatory Potentials Of Inkt Cells In Sepsis And Cancer., Joshua Choi
Electronic Thesis and Dissertation Repository
Invariant natural killer T (iNKT) cells are a unique unconventional T cell subset that recognize glycolipids presented by CD1d expressing cells. The prototypical glycolipid agonist of iNKT cells, α-Galactosylceramide (α-GalCer), can induce the rapid release of an arsenal of cytotoxic effector molecules and enormous amounts of immunomodulatory cytokines as early as two hours after activation. In addition to α-GalCer, various glycolipid agonists are available that allow for specific, in vivo targeting of iNKT cells, and can exert divergent T-helper (TH)1 and/or TH2 immune responses. Therefore, the type of response instigated by iNKT cells can profoundly influence …
Mechanisms Of Cross-Presentation By Cdc1s, Derek James Theisen
Mechanisms Of Cross-Presentation By Cdc1s, Derek James Theisen
Arts & Sciences Electronic Theses and Dissertations
Classical dendritic cells (cDCs) are specialized antigen presenting cells that can be divided into distinct subsets based on the types of pathogens they respond to and the type of immune response they generate. The cDC1 subset is specialized in priming CD8 T cell responses through the process of cross-presentation. During cross-presentation, exogenous protein antigens are taken up by cDC1 and presented on MHCI molecules, allowing for the priming of CD8 T cells during conditions when DCs themselves are not directly infected. The ability to cross-present in vivo is unique to cDC1, and is essential for anti-viral responses and rejection of …
Genomic And Transcriptomic Alterations In Metabolic Regulators And Implications For Anti-Tumoral Immune Response, Ryan J. King
Genomic And Transcriptomic Alterations In Metabolic Regulators And Implications For Anti-Tumoral Immune Response, Ryan J. King
Theses & Dissertations
Metabolic and immune alterations are ubiquitous hallmarks of cancer that are established during the foundational mutations and are further selected upon to generate highly aggressive tumors. Recent evidence suggests that cancer cells employ an altered metabolism to induce immune evasion. To further discover the relationship between metabolism and immunity in cancer, this thesis aimed to discover potential candidates of interest by first examining the mucin family for differences, as they exert a wide range of activities in cancer, including altered metabolism and immune alterations. Unique differences lead to further profiling in pancreatic and esophageal cancer. In pancreatic cancer, CD73 was …

From Development To Therapy: A Panoramic Approach To Further Our Understanding Of Cancer, Brittany Poelaert
Theses & Dissertations
Solid tumors, such as pancreatic cancer, often result in dismally low survival outcomes for patients due to insufficient understanding of disease development and progression. Pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States and although oncogenic drivers (such as KRAS mutation or loss of tumor suppressor p53) and stages of disease development have been studied, further understanding of pancreatic cancer development is greatly needed. Studies from our laboratory have identified novel and varied functions of amyloid precursor-like protein 2 (APLP2) in the development and progression of pancreatic cancer. These functions include promoting cancer cell migration, …

Doctoral Dissertations
Cancer is a deadly malignant disease that is costly to treat and still impossible to cure. Cancer treatments often come with side effects that impact the overall health of patients. Breast cancer is the most common type of cancer in the United State and bladder cancer mortality and recurrence rates are still high among cancer patients. Thus, safe and effective regimens are needed to combat these diseases.
In this study, the safe and efficacious combination of gemcitabine, cisplatin, and romidepsin (Gem plus Rom+Cis) to treat two types of cancer: bladder and breast cancer, was formulated. In vitro data from this …
Genetic Analysis Of Pi3k And Mtor Inhibition In U87mg Glioblastoma Cell Line, Carl G. Litif
Genetic Analysis Of Pi3k And Mtor Inhibition In U87mg Glioblastoma Cell Line, Carl G. Litif
Theses and Dissertations
NVP-BEZ235 is a Glioblastoma Multiform chemotherapeutic dual PI3K/mTOR pathway inhibitor created in 2008 and has since been proven experimentally to induce pluripotentcy in oncological cell populations. The inhibition of PI3K and mTOR has shown to coerce phenotypes associated with stem cell markers, most notably OCT4. It is necessary to understand the genetic composure of how PI3K/mTOR inhibited tumor cells are bypassing the canonical pathway for proliferation and growth and utilizing other parallel sources for tumor invasion into other neural regions. Taking a genetic approach with RNA-sequencing allowed us to gain insight into how glioblastoma interact with cytoskeleton factors MAPK4 and …
Statistical Methods For Resolving Intratumor Heterogeneity With Single-Cell Dna Sequencing, Alexander Davis
Statistical Methods For Resolving Intratumor Heterogeneity With Single-Cell Dna Sequencing, Alexander Davis
Dissertations & Theses (Open Access)
Tumor cells have heterogeneous genotypes, which drives progression and treatment resistance. Such genetic intratumor heterogeneity plays a role in the process of clonal evolution that underlies tumor progression and treatment resistance. Single-cell DNA sequencing is a promising experimental method for studying intratumor heterogeneity, but brings unique statistical challenges in interpreting the resulting data. Researchers lack methods to determine whether sufficiently many cells have been sampled from a tumor. In addition, there are no proven computational methods for determining the ploidy of a cell, a necessary step in the determination of copy number. In this work, software for calculating probabilities from …
Elucidating Mechanisms Of Metastasis With Implantable Biomaterial Niches, Ryan Adam Carpenter
Elucidating Mechanisms Of Metastasis With Implantable Biomaterial Niches, Ryan Adam Carpenter
Doctoral Dissertations
Metastasis is the leading cause of cancer related deaths, yet it remains the most poorly understood aspect of tumor biology. This can be attributed to the lack of relevant experimental models that can recapitulate the complex and lengthy progression of metastatic relapse observed in patients. Mouse models have been widely used to study cancer, however they are critically limited to study metastasis. Most models generate aggressive metastases in the lung without the use of unique cell lines or specialized injection techniques. This limits the ability to study disseminated tumor cells (DTCs) in other relevant metastasis prone tissues. Prolonged observation of …
Survival-Related Clustering Of Cancer Patients By Integrating Clinical And Biological Datasets, Xinming Wei
Survival-Related Clustering Of Cancer Patients By Integrating Clinical And Biological Datasets, Xinming Wei
Master's Theses (2009 -)
Subtype-based treatments and drug therapies are essential aspects to be considered in cancer patients' clinical trials to provide appropriate personalized therapies. With the advancement of the next-generation sequencing technology, several computational models, integrating genomic and transcriptomic datasets (i.e., multi-omics) in the prediction of subtype-based classification in cancer patients, were emerged. However, integration of the prognostic features from the clinical data, related to survival risks with the multi-omics datasets in the prediction of different subtypes, is limited and an important research area to be explored. In this study, we proposed a data integration pipeline with the prognostic features from the clinical …
B Cell Acute Lymphoblastic Leukemia Is Driven By Activating Janus Kinase Mutations Cooperating With Spi1 And Spib Deletions In A Murine Model, Michelle Lim
Electronic Thesis and Dissertation Repository
B cell acute lymphoblastic leukemia (B-ALL) is caused by genetic lesions in developing B cells that function as drivers for accumulation of additional mutations in an evolutionary selection process. We investigated secondary drivers of leukemogenesis and their mechanism(s) of arising in a mouse model of B-ALL driven by PU.1/Spi-B deletion (Mb1-CreDPB). Whole exome sequencing revealed recurrent mutations in Jak3 (encoding Janus Kinase 3) and Jak1. Mutations with high variant allele frequency (VAF) were dominated by C->T transition mutations that were compatible with AID, whereas the majority of mutations, with low VAF, were dominated by C->A transversions associated with …
Effects Of Aurora Kinase C Expression On Retina Pigmented Epithelial Cell Migration, Proliferation, And Anchorage Independent Growth, Justin Bejar
Seton Hall University Dissertations and Theses (ETDs)
Cancer is a common and deadly disease in the United States with 1,806,590 new cancer cases in 2019 and 606,520 cancer deaths projected in 2020. These deaths are primarily due to the uncontrolled cell proliferation and migratory nature of the disease. Many cancer cells express genes normally restricted to meiotic cells. For example, Aurora Kinase C (AURKC) is known to regulate chromosome segregation in meiotic cells yet it is expressed in many different types of cancer, such as breast, prostate, colorectal, liver, cervical, thyroid, and testicular cancers. As a means to study the function of AURKC, an …

Multi-Omics Integration For Gene Fusion Discovery And Somatic Mutation Haplotyping In Cancer, Steven Mason Foltz
Arts & Sciences Electronic Theses and Dissertations
Cancer is a disease caused by changes to the genome and dysregulation of gene expression. Among many types of mutations, including point mutations, small insertions and deletions, large scale structural variants, and copy number changes, gene fusions are another category of genomic and transcriptomic alteration that can lead to cancer and which can serve as therapeutic targets. We studied gene fusion events using data from The Cancer Genome Atlas, including over 9,000 patients from 33 cancer types, finding patterns of gene fusion events and dysregulation of gene expression within and across cancer types. With data from the CoMMpass study (Multiple …

The Role Of The Cxcr3 Signaling Axes In Pancreatic Ductal Adenocarcinoma, Andrew C. Cannon
Theses & Dissertations
Numerous cytokines promote pancreatic ductal adenocarcinoma (PDAC) progression and suppress anti-tumor immune response leading to poor prognosis in PDAC patients. Despite this, many cytokines, have not been investigated in PDAC. Bioinformatic analyses of PDAC microarray and RNA-Seq datasets were used to identify cytokines overexpressed in PDAC, confirm the expression of cognate receptors, determine the association of cytokines with patient survival and define key underlying molecular associations. Bioinformatic findings were validated using immunohistochemical (IHC) staining, comparative cytokine qPCR-array in KrasLSL-G12D:TP53LSL-R172H:Pdx1-Cre (KPC) and KrasLSL-G12D:Pdx1-Cre (KC) PDAC models and multicolor immunofluorescence staining. Tail-vein injections of PDAC cells …
