Functional Role Of The Homeobox Transcription Factor Six1 In Neoplastic Transformation Of Human Keratinocytes, Maria Hosseinipour
Functional Role Of The Homeobox Transcription Factor Six1 In Neoplastic Transformation Of Human Keratinocytes, Maria Hosseinipour
Theses and Dissertations
The homeobox transcription factor SIX1 contributes to both tumor development and progression. Numerous studies have determined that the inappropriate expression of embryonic genes, in particular transcription factors, contributes to carcinogenesis. SIX1 is essential for the development of numerous organs including the auditory and olfactory system as well as the kidney, by promoting proliferation, survival and migration of progenitor cells during embryogenesis. SIX1 has also been shown to increase cancer cell proliferation, survival and invasion. The aberrant expression of SIX1 occurs in numerous adult and pediatric cancers. We have previously determined that our in-vitro model system for HPV16-mediated tumorigenesis shares many …
Garlic Inhibits Inflammation During Dengue Infection, Alex R. Hall
Garlic Inhibits Inflammation During Dengue Infection, Alex R. Hall
Theses and Dissertations
Dengue virus (DENV) is a mosquito-borne flavivirus that causes significant human disease and mortality in the tropics and subtropics. There has been a recent global trend of increased epidemic activity, and DENV infection is considered a serious emerging health problem worldwide. A relatively unexplored approach to develop new treatments for dengue virus infection and the prevention of severe disease development is through investigation of natural medicines. Inflammation plays both beneficial and harmful roles during the host response to dengue virus infection. Several studies have proposed that it is the oxidative stress response induced by dengue virus infection that is responsible …
Individual Differences In Markers Of Cholinergic Signaling Correlating To Fear And Extinction Learning, Grace C. Jones
Individual Differences In Markers Of Cholinergic Signaling Correlating To Fear And Extinction Learning, Grace C. Jones
Theses and Dissertations
Posttraumatic stress disorder (PTSD) results when individuals are exposed to a life threatening event, assault, serious injury, or other traumatic incident. Individuals with PTSD are impaired in their ability to extinguish fear memories, resulting in intrusive symptoms that impair their ability to live otherwise healthy lives. It remains unclear why some individuals exposed to traumatic events develop PTSD while others do not. Acetylcholine has been shown to play a critical role in fear learning, but its role in fear extinction is not well understood. This study utilized a rat model of fear learning and extinction to determine if individual differences …
Muscarinic Acetylcholine Receptor M1’S Impact On Fear Extinction Learning, Joshua R. Mcelroy
Muscarinic Acetylcholine Receptor M1’S Impact On Fear Extinction Learning, Joshua R. Mcelroy
Theses and Dissertations
Post-Traumatic Stress Disorder (PTSD) is a mental health disorder that can occur following a traumatic event like combat, assault, or disaster. Individuals with PTSD are unable to extinguish fear memories which can become chronic and disabling. However, it remains unclear why some individuals exposed to a traumatic event develop PTSD while others are resilient. Acetylcholine plays a critical role in fear learning, but its role in fear extinction is less well understood. In this investigation, we used a rat model of fear extinction to determine if individual differences in extinction learning are correlated with markers of cholinergic signaling. Cholinergic markers …
Succination Impairs Protein Folding And Promotes Chop Stability In The Adipocyte During Diabetes, Allison Manuel
Succination Impairs Protein Folding And Promotes Chop Stability In The Adipocyte During Diabetes, Allison Manuel
Theses and Dissertations
Type 2 diabetes mellitus has been diagnosed in ~21 million people in the United States and is closely correlated with obesity, prompting the need for a detailed understanding of adipocyte metabolism in the development of diabetes. The intake of excess nutrients surpasses the energy requirements of the cell and leads to increased mitochondrial stress in the adipocyte. We have shown that this is associated with increased levels of the mitochondrial metabolite fumarate. Fumarate can react with cysteine thiol groups to form the chemical modification S-(2-succino)cysteine (2SC), also termed protein succination. Succination is significantly increased in the adipose tissue of type …
Synergism Of Quercetin And Sodium Butyrate For Controlling Growth Of Glioblastoma, Matthew Alan Taylor
Synergism Of Quercetin And Sodium Butyrate For Controlling Growth Of Glioblastoma, Matthew Alan Taylor
Theses and Dissertations
Glioblastoma multiforme (GBM), or simply glioblastoma, is the most common and aggressive primary brain tumor, with a prevalence of approximately 20,000 new cases per year in the United States and a 3-year survival rate of just 2%. Quercetin (QCT) is a dietary flavonoid that can be found in common foods such as red kidney beans, cilantro, and onions. Despite little evidence showing any benefits through dietary intake of QCT, various studies show its promising anti-cancer results in vitro. In glioblastoma, QCT is able to cause significant amounts of apoptosis through a variety of mechanisms. These include activation of caspase-9 and …
