Brd4 Binds To Active Enhancers To Control Cell Identity Gene Induction In Adipogenesis And Myogenesis, Ji-Eun Lee, Young-Kwon Park, Sarah Park, Younghoon Jang, Nicholas Waring, Anup Dey, Keiko Ozato, Binbin Lai, Weiqun Peng, Kai Ge

Anatomy and Regenerative Biology Faculty Publications

The epigenomic reader Brd4 is an important drug target for cancers. However, its role in cell differentiation and animal development remains largely unclear. Using two conditional knockout mouse strains and derived cells, we demonstrate that Brd4 controls cell identity gene induction and is essential for adipogenesis and myogenesis. Brd4 co-localizes with lineage-determining transcription factors (LDTFs) on active enhancers during differentiation. LDTFs coordinate with H3K4 mono-methyltransferases MLL3/MLL4 (KMT2C/KMT2D) and H3K27 acetyltransferases CBP/p300 to recruit Brd4 to enhancers activated during differentiation. Brd4 deletion prevents the enrichment of Mediator and RNA polymerase II transcription machinery, but not that of LDTFs, MLL3/MLL4-mediated H3K4me1, and …

The Effect Of K562-Il21-2 Plasma Membrane Particles On The Proliferation Of Natural Killer Cells To Fight Cancer, Michelle Prophete

Honors Undergraduate Theses

Immunotherapy has emerged as a current and future paradigm of cancer treatment, which utilizes the body’s immune system to eradicate cancer. Natural Killer (NK) cells as part of the innate immune system have immense potential in their anti-tumor cytotoxic activities and host cell surveillance properties. NK cells comprise approximately five to fifteen percent of peripheral blood lymphocytes and can be proliferated in vitro using recently developed methods with co-cultures with feeder cells (derived from engineered tumor cells) or plasma membrane (PM) particles, produced from the fore mentioned feeder cells, in combination with soluble cytokines. For efficient growth and maintenance of …

Characterization Of Malt1 Inhibitors And Their Effect On Leukemic Cell Growth Properties, Christina Snyder

Graduate School of Biomedical Sciences Theses and Dissertations

Leukemia is the most common childhood cancer, with a combined 40,000 predicted new cases in the United States in 2016 [8]. The two most common subtypes are acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL) [9-11]. The commercially available inhibitor of Bruton’s tyrosine kinase (BTK) has shown promising results in clinical trials for CLL because of the importance of BCR signaling in CLL [12-15]. Recent studies suggest that the outgrowth of BTK inhibitor resistant clonal cells in some CLL patients results in a treatment-refractory phenotype [16-18]. MALT1, a protein involved in BCR activation of the NF-κB pathway that functions …

Development Of Cellular Assays To Monitor Enzymatic And Biological Activity Of Cd73: A Key Modulator Of Anti-Tumor Immune Response, Alexandra Fanuka

Graduate School of Biomedical Sciences Theses and Dissertations

Ecto-5’-nucleotidase, known as CD73, is an extracellular enzyme that converts adenosine monophosphate (AMP) to adenosine and has recently been identified as a potential drug target for cancer immunotherapy. Its immunosuppressive effects, mediated by the activity of adenosine, are associated with higher rates of tumor invasion and metastasis, as well as poorer prognoses overall in many cancer types. CD73 is often co-expressed with ectonucleoside triphosphate diphosphohydrolase-1 (CD39), which catalyzes the conversion of adenosine triphosphate (ATP) to adenosine diphosphate (ADP), and ADP to AMP on the surface of tumor cells. Dual expression further propagates immunosuppressive effects of adenosine in the tumor microenvironment. …

Biomuta And Bioxpress: Mutation And Expression Knowledgebases For Cancer Biomarker Discovery, Hayley Dingerdissen, John Torcivia-Rodriguez, Yu Hu, Ting-Chia Chang, Raja Mazumder, Robel Kashay

Biochemistry and Molecular Medicine Faculty Publications

Single-nucleotide variation and gene expression of disease samples represent important resources for biomarker discovery. Many databases have been built to host and make available such data to the community, but these databases are frequently limited in scope and/or content. BioMuta, a database of cancer-associated single-nucleotide variations, and BioXpress, a database of cancer-associated differentially expressed genes and microRNAs, differ from other disease-associated variation and expression databases primarily through the aggregation of data across many studies into a single source with a unified representation and annotation of functional attributes. Early versions of these resources were initiated by pilot funding for specific research …

Press-Pulse: A Novel Therapeutic Strategy For The Metabolic Management Of Cancer, Thomas Seyfried, George Yu, Joseph Maroon, Dominic D'Agostino

Urology Faculty Publications

Background

A shift from respiration to fermentation is a common metabolic hallmark of cancer cells. As a result, glucose and glutamine become the prime fuels for driving the dysregulated growth of tumors. The simultaneous occurrence of “Press-Pulse” disturbances was considered the mechanism responsible for reduction of organic populations during prior evolutionary epochs. Press disturbances produce chronic stress, while pulse disturbances produce acute stress on populations. It was only when both disturbances coincide that population reduction occurred.

Methods

This general concept can be applied to the management of cancer by creating chronic metabolic stresses on tumor cell energy metabolism (press disturbance) …

Therapeutic Potential Of Targeting Reactive Oxygen Species (Ros) Stress In Myelodysplastic Syndrome (Mds), Karine Z. Oben

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Myelodysplastic syndromes (MDS) are a diverse group of clonal hematologic disorders characterized by ineffective blood cell production (hematopoiesis), dysplastic (abnormal) cell morphology in one or more hematopoietic lineages, and progression to acute myeloid leukemia (AML). The response rate to current FDA approved therapies is low and not durable. Just about 50% of MDS patients respond to these drug therapies and a majority of responders relapse within 2-3 years. Hence there is a compelling need to investigate new therapy options.

We investigated the anticancer potential and possible underlying molecular mechanisms of action of a plant-derived compound, Withaferin A (WFA) in MDS. …

Pioglitazone, Neet Family Proteins, And Galactose Modulation Of Liver Cell Bioenergetics, David F. Grimm

Undergraduate Honors Theses

MitoNEET was discovered through interactions with a labeled and photoactive derivative of pioglitazone (pio), a drug used to increase peripheral insulin sensitivity. Its unique coordination of a [2Fe-2S] cluster by three cysteine residues (Cys-72, Cys-74, and Cys-83) and one histidine (His-87) gives this cluster both stability and the ability to be donated to acceptor proteins. These qualities allow mitoNEET to participate in a diversity of biological functions. Functions of mitoNEET and the consequences of pioglitazone (pio) treatment in human hepatocellular carcinoma (HepG2) cells cultured in glucose or galactose-based medium were examined by respiration and proliferation studies. Pio treatment decreased complex …

Anti-Cancer And Bioavailabilty Of Arachidin-1 And Arachidin-3 In Colon Cancer Cells, Macy R. Shirley, Cindi Brownmiller, Wing Shun Lam, Sun-Ok Lee

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Cancer is a common cause of death in the United States and locally in the state of Arkansas. Modifiable factors such as tobacco use, physical activity, and diet lead to reduced incidence of colon cancer diagnosis. Plant-based foods may contain phytochemicals that confer health promoting properties. Specifically, peanuts contain phytochemicals known as resveratrol, arachidin-1, and arachidin-3 that have been linked to anticancer activities. However, few research studies have been done on arachidin-1 and arachidin-3 that could develop understanding of their health promoting properties or nutraceutical applications. The objectives of this study were to (1) determine the most effective concentration of …

Genetic Markers In Circulating Tumour Cells As A Measure Of The Metastatic Propensity Of Uveal Melanoma, Aaron Beasley

Theses: Doctorates and Masters

Background: Uveal melanoma (UM) is an extremely aggressive disease with approximately 50% of patients developing incurable metastatic disease. Therefore, accurate prognosis of a patient is necessary for closer follow up and the earlier implementation of systemic adjuvant therapies in those most likely to develop metastatic disease. Fortunately, UM can be classified into two distinct molecular classes based on clinically validated gene expression profiling, chromosomal aberrations and specific driver mutations, which accurately predict the metastatic propensity of the primary tumour. However, genetic testing currently requires biopsy of the eye which can lead to serious complications including permanent blindness. Therefore, an alternative …

Cellular And Molecular Mechanisms Underlying Alcohol-Induced Aggressiveness Of Breast Cancer, Yongchao Wang, Mei Xu, Zun-Ji Ke, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Breast cancer is a leading cause of morbidity and mortality in women. Both Epidemiological and experimental studies indicate a positive correlation between alcohol consumption and the risk of breast cancer. While alcohol exposure may promote the carcinogenesis or onset of breast cancer, it may as well enhance the progression and aggressiveness of existing mammary tumors. Recent progress in this line of research suggests that alcohol exposure is associated with invasive breast cancer and promotes the growth and metastasis of mammary tumors. There are multiple potential mechanisms involved in alcohol-stimulated progression and aggressiveness of breast cancer. Alcohol may increase the mobility …

Effects Of Chromium On Mouse Splenic T Lymphocytes And Effects Of Ethanol Exposure During Early Neurodevelopment On Behaviors In Mice, Lu Dai

Theses and Dissertations--Toxicology and Cancer Biology

The dissertation consists of three major projects with the focus on the immunotoxicity of chromium and the behavior disorders caused by early ETOH exposure respectively.

Hexavalent chromium [Cr(VI)] is widely used in various industrial processes and has been recognized as a carcinogen. As the first line of host defense system, the immune system can be a primary target of Cr(VI). T cell population represents a major arm of the immune system that plays a critical role in host anti-tumor immunity. Dysfunction of T cells compromises host anti-tumor immunity resulting in oncogenesis. Using mouse splenic T cells as an in vitro …
