NEMO Prevents Steatohepatitis and Hepatocellular Carcinoma by Inhibiting RIPK1 Kinase Activity-Mediated Hepatocyte Apoptosis.

IκB kinase/nuclear [corrected] factor κB (IKK/NF-κB) signaling exhibits important yet opposing functions in hepatocarcinogenesis. Mice lacking NEMO in liver parenchymal cells (LPC) spontaneously develop steatohepatitis and hepatocellular carcinoma (HCC) suggesting that NF-κB prevents liver disease and cancer. Here, we show that complete NF-κB inhibition by combined LPC-specific ablation of RelA, c-Rel, and RelB did not phenocopy NEMO deficiency, but constitutively active IKK2-mediated NF-κB activation prevented hepatocellular damage and HCC in NEMO(LPC-KO) mice.

Effects of Helicobacter pylori Eradication in Chronic Spontaneous Urticaria: Results from a Retrospective Cohort Study.

Background And Objective: Helicobacter pylori (Hp) infection has been hypothesised to play a major role in the pathogenesis of chronic spontaneous urticaria (CSU). Despite only weak evidence from Hp eradication studies, screening for Hp infection is still recommended in several CSU guidelines. The aim of this study was to investigate the effect of Hp eradication in combination with standard CSU treatment in Hp-positive compared with Hp-negative patients, applying the latest guidelines for both diseases.

Augmented renal vancomycin clearance in cancer patients: a case report and review of the literature.

Background: Bacterial infections are a major cause of morbidity and mortality in cancer patients. Particularly diagnostic and therapeutic procedures (e.g.

Vital staining of blood vessels and bile ducts with carboxyfluorescein diacetate succinimidyl ester: a novel tool for isolation of cholangiocytes.

Background And Aim: Current methods for visualization of the blood vasculature, biliary tree and for isolation of vital cholangiocytes are afflicted with a plethora of technical difficulties, especially in mice. In this project, we propose a novel, reliable and straightforward alternative technique for histological demonstration of blood- and biliary systems and derivation of vital cholangiocytes.

Methods: Intravital retrograde perfusion of bile ducts was performed in twenty wild type mice.

Neighbor of Punc E 11: expression pattern of the new hepatic stem/progenitor cell marker during murine liver development.

We have previously identified Neighbor of Punc E 11 (Nope) as a specific cell surface marker of stem/progenitor cells in the murine fetal liver that is also expressed in hepatocellular carcinoma. Here, we focus on the differential expression pattern of Nope during murine fetal and postnatal liver development as well as in a normal and regenerating adult liver including oval cell activation. In the fetal liver, Nope shows a constantly high expression level and is a useful surface marker for the identification of Dlk, E-cadherin, and CD133-positive hepatoblasts by flow cytometry.

Neighbor of Punc E11, a novel oncofetal marker for hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the 5th common malignancy worldwide, but established markers fail to detect up to one third of HCC. We have recently identified Neighbor of Punc E11 (Nope) as a surface marker for murine fetal liver stem cells. Similar to commonly used HCC markers such as α-Fetoprotein (Afp) and Glypican-3 (Gpc-3), we here establish Nope as an oncofetal marker of murine and human HCC and investigate its specific expression in hepatoma cell lines and primary HCC.
