Acute Diagnosis Of Wilson’S Disease In A Teenage Patient, Sarah Irvin, Ryan Mccarthy
Acute Diagnosis Of Wilson’S Disease In A Teenage Patient, Sarah Irvin, Ryan Mccarthy
Marshall Journal of Medicine
Wilson’s Disease, a rare autosomal recessive genetic disease, is caused by a mutation in the ATP7B enzyme gene. Without this enzyme, copper builds up in the brain, liver, and cornea causing a multitude of symptoms. It is important to consider Wilson’s disease because the prognosis is dependent on timely diagnosis. This is an interesting case of a 19-year-old male who presented with suicidal thoughts and rapid weight loss. After many months and an extensive work-up, Wilson’s Disease was diagnosed. Due to his rapid decline, he was transferred to a larger university healthcare center where he is currently enrolled in clinical …

Transplantation of adult human hepatic stem/progenitor cells (hHSPCs) has been considered as an alternative therapy, replacing donor liver transplantation to treat liver cirrhosis. This study assessed the antifibrotic effects of hHSPCs in mice with fibrosis induced by carbon tetrachloride (CCl4) and examined the actions of hHSPCs on the fibrogenic activity of human hepatic stellate cells (HSCs) in a coculture system. Isolated hHSPCs expressed stem/progenitor cell phenotypic markers. Mice were given CCl4 (twice weekly for 7 weeks) and hHSPC transplantation weekly. CCl4 induced advanced fibrosis (bridging fibrosis and cirrhosis) in mice, which was prevented by hHSPC transplantation. …
Autophagy Protects Against Cyp2e1/Chronic Ethanol-Induced Hepatotoxicity, Yongke Lu, Arthur I. Cederbaum
Autophagy Protects Against Cyp2e1/Chronic Ethanol-Induced Hepatotoxicity, Yongke Lu, Arthur I. Cederbaum
Pharmacology, Physiology and Toxicology
Autophagy is an intracellular pathway by which lysosomes degrade and recycle long-lived proteins and cellular organelles. The effects of ethanol on autophagy are complex but recent studies have shown that autophagy serves a protective function against ethanol-induced liver injury. Autophagy was found to also be protective against CYP2E1-dependent toxicity in vitro in HepG2 cells which express CYP2E1 and in vivo in an acute alcohol/CYPE1-dependent liver injury model. The goal of the current report was to extend the previous in vitro and acute in vivo experiments to a chronic ethanol model to evaluate whether autophagy is also protective against CYP2E1-dependent liver …
