Role Of Adenylyl Cyclase Type 7 In Functions Of Bv-2 Microglia, Yawen Hu, Rebecca A. Hill, Masami Yoshimura

School of Medicine Faculty Publications

To assess the role of adenylyl cyclase type 7 (AC7) in microglia’s immune function, we generated AC7 gene knockout (AC7 KO) clones from a mouse microglial cell line, BV-2, using the CRISPR-Cas9 gene editing system. The ability of BV-2 cells to generate cAMP and their innate immune functions were examined in the presence or absence of ethanol. The parental BV-2 cells showed robust cAMP production when stimulated with prostaglandin-E1 (PGE1) and ethanol increased cAMP production in a dose-dependent manner. AC7 KO clones of BV-2 cells showed diminished and ethanol-insensitive cAMP production. The phagocytic activity of the parental BV-2 cells was …

The Relationship Between Alcohol Use And Familial And Social Influence In College Nursing Students, Darren C. Crooks, Kathleen A. Gillota

Williams Honors College, Honors Research Projects

College students are a population with a high prevalence of risky consumption of alcohol and nursing students, specifically, are no exception. Yet few studies have been done on the use of alcohol in the student-nurse population. Since nursing education and practice are highly stressful, unhealthy coping strategies, such as risky alcohol consumption, are sadly common and seriously detrimental.

This paper explores the self-reported consumption of alcohol in undergraduate nursing students as related to peer, familial, and social influences. Based on the Biopsychosocial Model, many different factors contribute to alcohol use. Using anonymous online survey methodology and convenience sampling, data about …

Increased Number Of Circulating Exosomes And Their Microrna Cargos Are Potential Novel Biomarkers In Alcoholic Hepatitis, Fatemeh Momen-Heravi, Banishree Saha, Karen Kodys, Donna Catalano, Abhishek Satishchandran, Gyongyi Szabo

BACKGROUND: It has been well documented that alcohol and its metabolites induce injury and inflammation in the liver. However, there is no potential biomarker to monitor the extent of liver injury in alcoholic hepatitis patients. MicroRNAs (miRNAs) are a class of non-coding RNAs that are involved in various physiologic and pathologic processes. In the circulation, a great proportion of miRNAs is associated with extracellular vesicles (EVs)/exosomes. Here, we hypothesized that the exosome-associated miRNAs can be used as potential biomarkers in alcoholic hepatitis (AH).

METHODS: Exosomes were isolated from sera of alcohol-fed mice or pair-fed mice, and plasma of alcoholic hepatitis …
