p62/Sequestosome-1 Is Indispensable for Maturation and Stabilization of Mallory-Denk Bodies
Mallory-Denk bodies (MDBs) are hepatocytic protein aggregates found in steatohepatitis and several other chronic liver diseases as well as hepatocellular carcinoma. MDBs are mainly composed of phosphorylated keratins and stress protein p62/Sequestosome-1 (p62), which is a common component of cytoplasmic aggregates in a variety of protein aggregation diseases. In contrast to the well-established...
متن کاملMallory Denk Body Formation in Alcoholic Hepatitis: The Pivotal Role of Interleukin-8 Signaling
Mallory-Denk Bodies (MDBs) are prevalent in various liver diseases including alcoholic hepatitis (AH) and are formed in mice livers by feeding diethyl 1,4-dehydro-2,4,6trimethyl-3,5-pyridine-dicarboxylate (DDC). The chemokine CXCL8, also known as interleukin-8 (IL-8) and its receptors are involved in oncogenesis and in tumor progression, invasion, and metastasis. We reported previously the mark...
متن کاملSensitivity and Specificity of In situ Proximity Ligation for Protein Interaction Analysis in a Model of Steatohepatitis with Mallory-Denk Bodies
The in situ proximity ligation assay (isPLA) is an increasingly used technology for in situ detection of protein interactions, post-translational modifications, and spatial relationships of antigens in cells and tissues, in general. In order to test its performance we compared isPLA with immunofluorescence microscopy by analyzing protein interactions in cytoplasmic protein aggregates, so-called...
متن کاملOxidative stress, Nrf2 and keratin up-regulation associate with Mallory-Denk body formation in mouse erythropoietic protoporphyria.
UNLABELLED Mallory-Denk bodies (MDBs) are hepatocyte inclusions commonly seen in steatohepatitis. They are induced in mice by feeding 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) for 12 weeks, which also causes porphyrin accumulation. Erythropoietic protoporphyria (EPP) is caused by mutations in ferrochelatase (fch), and a fraction of EPP patients develop liver disease that is phenocopied in...
متن کاملMallory bodies in alcoholic and non-alcoholic liver disease contain a common antigenic determinant.
An immunohistochemical technique is described for the detection of Mallory bodies (MBs) in paraffin sections of liver tissue. This is based on proteolytic digestion of sections before exposure to an antiserum which recognises a unique antigenic determinant in MBs. With the use of this procedure it has been shown in alcoholic liver disease, primary biliary cirrhosis. Indian childhood cirrhosis, ...
