Etracellular Vesicles From Lactobacillus Rhamnosus Gg Protect Against Alcohol-Induced Liver Injury Through Suppression Of Intestinal Mir 194 And Subsequent Activation Of Fxr In Mice., Mengwei Jiang May 2022

Etracellular Vesicles From Lactobacillus Rhamnosus Gg Protect Against Alcohol-Induced Liver Injury Through Suppression Of Intestinal Mir 194 And Subsequent Activation Of Fxr In Mice., Mengwei Jiang

Numerous studies have reported the efficacy of probiotics for alcohol-associated liver disease (ALD). These studies indicate a strong interest among the scientific and medical communities in identifying alternative or adjunctive approaches for ALD, for which there is no effective or widely accepted therapeutic option. However, in-depth molecular knowledge on how probiotics render their effects is lacking. Patients with ALD often have increased hepatic bile acids (BAs), which can be toxic and are an important causative factor in liver injury and hepatocyte death. BAs are released into the intestines and serve not only as a “detergent” to promote fat absorption, but …


Pde4 Inhibition: A Novel Therapeutic Strategy In Liver Fibrosis., Mohamed Elnagdy May 2021

Pde4 Inhibition: A Novel Therapeutic Strategy In Liver Fibrosis., Mohamed Elnagdy

Electronic Theses and Dissertations

Background: Liver fibrosis is accumulation of extracellular matrix (ECM) proteins due to chronic liver injury. Chronic hepatic damage can occur due to multiple causes including, alcohol, non-alcoholic steatohepatitis and chronic viral hepatitis. Liver fibrosis is a critical problem worldwide due to the extremely high incidence of alcohol associated liver damage and chronic viral hepatitis. Moreover, there is no FDA approved therapy for liver fibrosis. Activation and transdifferentiation of quiecent hepatic stellate cells (HSCs) to myofibroblasts (MFBs) is the main event contributing to liver fibrosis. This process involves two phases, the initiation and the perpetuation phases. Hepatocyte injury and inflammatory response …


Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin May 2019

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …


The Influence Of Mir-99a On Mtor Signaling Regulation In Colorectal Cancer Cell Lines., Jonathan Rice May 2016

The Influence Of Mir-99a On Mtor Signaling Regulation In Colorectal Cancer Cell Lines., Jonathan Rice

Electronic Theses and Dissertations

Colorectal cancer (CRC) is the third most common cancer worldwide and the fourth most common cause of death. These are staggering statistics for a disease that can essentially be cured if caught early and the pathology is favorable to therapeutic intervention. There is currently a drastic decrease in five year survival as the cancer stage increases from locally confined disease to metastatic disease. These statistics suggest that although some strides have been made with colon cancer screening and early intervention, there is still much room for improvement in both screening and treatment of CRC. One of the pathways that have …


Acrolein Is A Critical Mediator Of Alcohol-Induced Liver And Intestinal Injury In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen May 2016

Acrolein Is A Critical Mediator Of Alcohol-Induced Liver And Intestinal Injury In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen

Electronic Theses and Dissertations

Alcohol consumption can cause alcoholic liver disease (ALD), which remains a major cause of morbidity and mortality in the United States. Chronic alcohol consumption causes a pro-oxidant environment in the liver and increases hepatic lipid peroxidation. Acrolein is the most reactive and toxic aldehyde generated through lipid peroxidation. Acrolein forms protein adducts and triggers endoplasmic reticulum (ER) stress and hepatocyte apoptosis, which are recognized etiologic factors in ALD. Several studies have established the critical role of the gut-liver axis in ALD pathogenesis, wherein alcohol-induced gut barrier dysfunction contributes to liver injury. This study investigates, in vitro and in vivo, the …


Pathogenic Role Of Acrolein In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen Dec 2014

Pathogenic Role Of Acrolein In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen

Electronic Theses and Dissertations

Alcohol is the most socially accepted addictive drug, and it can cause alcoholic liver disease (ALD), which is a major cause of morbidity and mortality in the United States and worldwide. Animal and human studies demonstrate that chronic alcohol consumption causes a pro-oxidant environment in the liver and increases hepatic lipid peroxidation and the accumulation of by-products such as acrolein and 4-hydroxynonenal. Acrolein is the most reactive and toxic aldehyde generated through lipid peroxidation. Also, acrolein is a major component of cigarette smoke, and there is increasing evidence that smoking negatively impacts the incidence, severity, and clinical course of chronic …
