Background: Biochanin A, an isoflavone that is mainly present in red clover, has potent chemopreventive properties against many cancers. Ovarian carcinoma is fifth most common and deadliest gynaecological malignancy that causes the highest mortality in females worldwide. Hence a substantial need for new therapies for combating this gynaecological malignancy arises.
Methods: The present study aimed to investigate anti-cancerous potentials of biochanin A on cultured human ovarian carcinoma PA-1 cells through the cell viability assay, cellular apoptosis, disruption of mitochondrial membrane potential (MMP), involvement of ROS, cell cycle kinetics, and expression of apoptosis-related genes namely, p53, Bax, Bcl-2, Noxa and Puma. …

Identification Of Tectorigenin As A Natural Pro-Hypoxia Compound: Implications In Modulation Of Cellular Differentiation And Senescence, Mallika Khurana, Renu Wadhwa, Sunil Kaul
Research Symposium
Background: Hypoxia, a suboptimal level of oxygen, evokes stress response in cells and activated hypoxia signaling has been largely established as a pro-metastasis and pro-angiogenic factor for tumor cells. On the other hand, age-related neurodegenerative disorders are characterized by hypoxic environment, accumulation of molecular garbage and induction of premature senescence. Several recent studies have reported anti-stress impact of the intermittent induction of hypoxia signaling in these cells.
Methods: Screening of a phytochemical library using Hypoxia Responsive Element (HRE) driven luciferase as a reporter was carried out to identify hypoxia-modulating phytochemicals. Activation of HIF-1a (master regulator of hypoxia signaling) was validated …
Early Stage Or Curable Cancer Diagnoses In Minorities: A Journey Of Survivors, Lora Asberry
Early Stage Or Curable Cancer Diagnoses In Minorities: A Journey Of Survivors, Lora Asberry
Master of Science in Integrative Biology Theses
Patients diagnosed with early-staged or curable forms of cancer experience physical, as well as, mental challenges associated with disease progression and treatment. Previous studies have demonstrated that minorities and underrepresented communities did not receive the same level of care in comparison to their non-minority counterparts. Previous studies have also demonstrated that health disparities among minorities affected their cancer journey. This study addressed: how medical disparities varied between minorities and non-minorities, the overall effects of the cancer diagnoses in minorities compared to non-minorities, whether these perspectives differed in male vs. female participants, and whether there were any possible communication barriers between …
Cytotoxic Activity Of Salvia Officinalis Extract Mediated By The Inhibition Of Jak2 In Breast Cancer, Salma Alawadi Dawood
Cytotoxic Activity Of Salvia Officinalis Extract Mediated By The Inhibition Of Jak2 In Breast Cancer, Salma Alawadi Dawood
Theses and Dissertations
Background: Breast cancer is the most common type of invasive cancer in women in their forties and fifties. Recent evidence suggests that JAK2/STAT3 signaling is constitutively active in breast cancer. Previous studies suggest that plant extracts, including Salvia Officinalis, have strong cytotoxic effects on breast cancer cells. The differential expression of miRNAs is also strongly linked to cancer development.
Aim: In the current study, we hypothesize that S. Officinalis extract suppresses JAK2 expression and has strong anticancer potential in MCF7 breast cancer cell lines.
Methods: GC-MS analysis showed the presence of flavonoids in dried leaf of …
Uncovering Molecular Targets To Overcome Immunosuppression In Non-Small Cell Lung Cancer With Acquired Tki Resistance, Sonia A. Patel
Uncovering Molecular Targets To Overcome Immunosuppression In Non-Small Cell Lung Cancer With Acquired Tki Resistance, Sonia A. Patel
Dissertations & Theses (Open Access)
Non-small cell lung cancer (NSCLC) remains the leading cause of cancer-related deaths worldwide. Targeted therapeutic agents, such as epidermal-like growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) or monoclonal antibodies targeting vascular endothelial growth factor (VEGF/R), can effectively inhibit upregulated signaling pathways driving tumorigenesis in NSCLC and many other cancers. Unfortunately, however, resistance to such targeted therapies inevitably arise in most patients and can occur through a variety of resistance mechanisms including genomic alterations and upregulation of bypass pathways. Additionally, patients who have acquired resistance to these targeted agents typically have tumors characterized by an immunosuppressive tumor microenvironment and thus …
Investigation Of The Role Of Dax-1 In The Hpa Axis In Human Adrenal Cells, Katerina N. Fargas
Investigation Of The Role Of Dax-1 In The Hpa Axis In Human Adrenal Cells, Katerina N. Fargas
Undergraduate Honors Theses
DAX-1 is a nuclear hormone orphan receptor that plays a key role in the development of reproductive tissues and steroid hormone production. The hypothalamic-pituitary-adrenal axis is the pathway for steroid hormone production, primarily glucocorticoids, mineralocorticoids, and adrenal androgens, in the human body. The mechanisms of DAX-1 in hormone production in the adrenal cortex of the HPA axis are not completely understood and, therefore, were the focus of this honors thesis research project. Due to the high level of DAX-1 expression, SW13 adrenal carcinoma cells were conducted for these experiments. We investigated whether glucocorticoids, specifically the synthetic glucocorticoid dexamethasone, had any …
Computational Modeling Of The Fanconi Anemia Gene Network And Its Connection To Cancer, Alyssa Warren-Belford
Computational Modeling Of The Fanconi Anemia Gene Network And Its Connection To Cancer, Alyssa Warren-Belford
Biological Sciences Undergraduate Honors Theses
Fanconi anemia (FA) is a rare genetic condition in which the cell’s DNA repair machinery is dysregulated, significantly increasing the chances of tumorigenesis. Further research is being done in order to improve patient outcomes and incidences of cancer. Our group created a computational model of the FA DNA repair gene network, which removes interstrand crosslinks found in damaged DNA and repairs it so DNA synthesis can continue. Computer simulations show the number of DNA damage indicators decreased as the pathway continued. This was expected as the FA pathway repairs DNA damage. The goal of this project was to provide further …

Dissecting The Role Of Selenoprotein P And Thioredoxin Reductase In Pancreatic Cancer Metabolism, Alyssa A. Abbas
Dissecting The Role Of Selenoprotein P And Thioredoxin Reductase In Pancreatic Cancer Metabolism, Alyssa A. Abbas
Dissertations, Master's Theses and Master's Reports
Pancreatic ductal adenocarcinoma (PDAC), the fourth leading cause of US cancer-related deaths, has a stark 5-year survival rate of 9%, emphasizing an urgent need for effective therapies. A well-established characteristic of cancer, metabolic dysregulation, presents an opportunity for developing therapies that target specific metabolic susceptibilities inherent in cancer cells. Our recent studies have discovered a susceptibility in PDAC; deprivation of cystine or blocking its uptake by erastin (a cystine transport inhibitor) triggers significant lipid peroxidation, thereby inducing ferroptosis specifically in the mesenchymal subtype of PDAC, but not in the epithelial subtype. This study aims to elucidate the roles of Selenoprotein …

In third-world countries, cervical cancer is the most prevalent and leading cause of death. It is affected by a variety of factors, including smoking, poor nutritional status, immunological inadequacy, and prolonged use of contraception. The Pap smear test, which is intended to prevent cervical cancer, finds preneoplastic changes in cervical epithelial cells. This study framework classified cervical cancer cells from Pap smears into five specified cell types using machine learning-based classification algorithms. The SIPaKMeD database is used in this investigation. This public dataset, which was manually cropped from 966 cluster cell images taken from Pap smear slides, has 4045 isolated …
Pre-Clinical Trials With Precision-Medicine Based Therapeutics In Basal-Like Patient-Derived Xenografts, David C. Boyd
Pre-Clinical Trials With Precision-Medicine Based Therapeutics In Basal-Like Patient-Derived Xenografts, David C. Boyd
Theses and Dissertations
Breast cancer treatments have improved over time, but the diseases seeing the most benefit from these improvements have the estrogen receptor, progesterone receptor, or are positive for HER2. Basal-like breast cancer tends to not have these biomarkers, which necessitates their treatment to be traditional, untargeted therapeutics which are less effective and tend to have harsh adverse effect profiles – this is an important unmet need. These studies utilize a variety of techniques, including tissue culture, viability assays, high-throughput screening, in vivo drug treatments and imaging, pathway analyses, molecular techniques such as Western blot, antibody arrays, RNA sequencing, sc RNA sequencing, …

Comparison Of Cell Cycle Gene Expression Between Ovarian Cancer Cell Line Skov3 And Non-Cancerous Cell Lines, Akayla Weatherby
Dissertations, Master's Theses and Master's Reports
Roughly 1% of women will be diagnosed with ovarian cancer during their lifetime. There are many different factors that impact how likely someone is to develop ovarian cancer including age, lifestyle, and family history. Ovarian cancer, like all cancers, occurs due to the accumulation of cancer cells that result from errors in the cell cycle or its regulation. Here, we studied how cell cycle gene expression was altered in the epithelial-like ovarian cancer cell line SKOV3, as compared to the pre-cancerous ovarian cell line FT282, and the non-cancerous foreskin fibroblast cell line BJ5Ta. The three cell lines were synchronized into …
