The Effect Of Ethanol Treatment On The Protein Content Of Difi Exosomes, Kenzie Rushing

Belmont University Research Symposium (BURS)

Colorectal cancer (CRC) is the second most common cause of cancer death in the United States in both men and women combined, second only to lung cancer.1 CRC metastasis is the primary cause of mortality largely due to therapy resistant cancer cells.2 Therefore, detection before metastasis is of great importance and could potentially lead to earlier detection and decreased mortality. Extracellular vesicles (EVs), including exosomes, are lipid bound vesicles secreted by cells3 that are involved in cell-cell communication and have been found to promote CRC progression and metastasis.4 The proteome of exosomes is thought to reflect that of the originating …

Effects Of The Selective Gsk3b Inhibitor, Tideglusib, On Ethanol Consumption, Anxiety-Like Behavior, Taste Preference, And Downstream Proteins, Sam Gottlieb, Douglas Bledsoe, Jessica L. Maltman, Alanna Morgan, Jennifer T. Wolstenholme, Michael F. Miles

Graduate Research Posters

Background: We have shown modulations in glycogen synthase kinase 3 beta (GSK3B) abundance or activity regulate ethanol consumption, suggesting potential as a therapeutic target for alcohol use disorder (AUD). Here we report the GSK3B inhibitor tideglusib’s actions on ethanol consumption, basal behaviors, and modulation of GSK3B targets.

Methods: C57BL/6J males and females received i.g. 200mg/kg tideglusib, except drinking-in-the-dark (males;100mg/kg i.p.). Drinking-in-the-dark (DID): Mice given 20% ethanol 4-hours, 4-days/week x 3 weeks and then i.p. tideglusib or vehicle x 4 days in a Latin Square design with ethanol consumption measured daily. Light/Dark Box: Mice gavaged with tideglusib or vehicle …

Ctrp3 And Alcoholic Liver Disease In Female Mice, Callie Root

Undergraduate Honors Theses

C1q TNF Related Protein 3 (CTRP3), is a cytokine that is primarily secreted from adipose tissue, which classifies it as an adipokine. Our previous research has shown that CTRP3 prevents alcoholic fatty liver disease (ALD) in male mice. However, even when accounting for confounding factors such as absolute and relative alcohol intake, females are more sensitive to the effects of consumption compared to male mice. Therefore, the goal of this project was to determine whether CTRP3 prevented ALD in female mice. Methods: Female wild type (WT) and female CTRP3 transgenic over expressing (Tg) mice were fed an ethanol containing liquid …

Stimuli-Responsive Gelators From Carbamoyl Sugar Derivatives And Their Responses To Metal Ions And Tetrabutylammonium Salts, Dan Wang, Anji Chen, Joedian Morris, Guijun Wang

Chemistry & Biochemistry Faculty Publications

Carbohydrate-based low molecular weight gelators (LMWGs) are interesting compounds with a variety of applications. In this research, a library of nineteen carbamate derivatives of N-acetyl-D-glucosamine were synthesized and characterized, and several derivatives were found to be effective LMWGs. They formed gels in pump oils as well as mixtures of water with ethanol or water with DMSO. The structures of the carbamoyl chains played an important role in the gelation properties, short chain aliphatic derivatives and phenyl carbamates formed gels in more solvents than certain aromatic and dimeric carbamates. The phenyl carbamate gelator was also selected for the encapsulation of …

The Effects Of Chronic Alcohol Consumption On Ovarian Function/ Morphology, Destiny Roberts

Undergraduate Honors Theses

Chronic alcohol (ethanol) consumption has been known to affect the major organs of the body and particularly the liver. However, the effects of chronic ethanol consumption on the female reproductive system remain relatively unstudied. A convenient way to study these effects is by analyzing laboratory mice that have been fed an ethanol diet for an extended period of time and comparing them to control mice. In this study, female mice were separated into control and ethanol fed groups. The mice were placed on their specified diets and observed over the course of six weeks. The mice were fed and weighed …

Do Rats Consume Ethanol To Regulate A Negative Emotion Induced By A Successive Negative Contrast Procedure?, Andrew Dieterich

Seton Hall University Dissertations and Theses (ETDs)

According to the self-medication hypothesis, individuals may consume drugs or alcohol, or engage in other behaviors in order to reduce a negative emotional state (Khantzian, 1985; Gross, 2013; Crum et al., 2013). Rats experiencing a negative state induced by various stressors (Bertholomey et al., 2010), or a decrease or loss in reward value of a sucrose solution (Manzo et al., 2015; Manzo et al., 2014) demonstrate increased consumption of alcohol. I used successive (SNC) and anticipatory negative contrast (ANC) procedures to further examine this hypothesis and the previous findings (Manzo et al., 2015), that rats increase consumption and preference for …

The Metabolism Of Alcohol: Risk And Protective Factors, Sydney E. Levan, Amy Adkins, Danielle Dick, Karen G. Chartier

Purpose: Abstract for poster submission to VCU Poster Symposium for

Undergraduate Research and Creativity

Title: The Metabolism of Alcohol: Risk and Protective Factors

Background: In 2002, it was reported by the National Institutes of Health that

60.3% of college aged students (18-22) drank alcohol in the past month of being

asked, as compared to 51.9% of those not in college. They also found that 20% of

college students met the criteria for at least one alcohol use disorder (AUDs)1.

Many genes have been linked to an increased risk for AUDs and how individuals

with various ethnic backgrounds respond to alcohol. …

Alcohol Facilitates Hcv Rna Replication Via Up-Regulation Of Mir-122 Expression And Inhibition Of Cyclin G1 In Human Hepatoma Cells, Wei Hou, Terence Bukong, Karen Kodys, Gyongyi Szabo

Gyongyi Szabo

BACKGROUND: Clinical studies demonstrate synergistic liver damage by alcohol and hepatitis C virus (HCV); however, the mechanisms by which alcohol promotes HCV infection remain obscure. The liver-specific microRNA-122 (miR-122) regulates HCV replication and expression of host genes, including Cyclin G1. Here, we hypothesized that alcohol regulates miR-122 expression and thereby modulates HCV RNA replication. METHODS: The J6/JFH/Huh-7.5 model of HCV infection was used in this study. Real-time quantitative polymerase chain reaction, Western blotting, electrophoretic mobility shift assay, and confocal microscopy were used for experimental analysis. RESULTS: We found that acute alcohol exposure (25 mM) significantly increased intracellular HCV RNA as …

Dietary Folate, Alcohol Consumption, And Risk Of Ovarian Cancer In An Italian Case-Control Study, Claudio Pelucchi, Monia Mereghetti, Renato Talamini, Eva Negri, Maurizio Montella, Valerio Ramazzotti, Silvia Franceschi, Carlo La Vecchia

Department of Public Health Scholarship and Creative Works

An increasing number of studies are focusing on the potential association between dietary folate intake and risk of various cancers (1), particularly of the colorectum and breast (2, 3). A low folate status can induce misincorporation of uracil into DNA, leading to chromosome breaks in humans and hence increasing cancer risk (4). Alcohol may increase folate requirements in the body and cause relative folate deficiencies (2). Although several findings on the relation between folate intake and ovarian cancer risk are inconsistent (5-9), recent results from two prospective …
