Vaccines targeting preS1 domain overcome immune tolerance in hepatitis B virus carrier mice

Yingjie Bian, Zheng Zhang, Zhichen Sun, Juanjuan Zhao, Danming Zhu, Yang Wang, Sherry Fu, Jingya Guo, Longchao Liu, Lishan Su, Fu‐Sheng Wang, Yang‐Xin Fu, Hua Peng – 26 April 2017 – Strong tolerance to hepatitis B virus (HBV) surface antigens limits the therapeutic effect of the conventional hepatitis B surface antigen (HBsAg) vaccination in both preclinical animal models and patients with chronic hepatitis B (CHB) infection. In contrast, we observed that clinical CHB patients presented less immune tolerance to the preS1 domain of HBV large surface antigen.

Polo‐like‐kinase 1 is a proviral host factor for hepatitis B virus replication

Ahmed Diab, Adrien Foca, Floriane Fusil, Thomas Lahlali, Pascal Jalaguier, Fouzia Amirache, Lia N'Guyen, Nathalie Isorce, François‐Loïc Cosset, Fabien Zoulim, Ourania Andrisani, David Durantel – 26 April 2017 – Chronic hepatitis B virus (HBV) infection is a major risk factor for hepatocellular carcinoma (HCC) and current treatments for chronic hepatitis B and HCC are suboptimal. Herein, we identified cellular serine/threonine Polo‐like‐kinase 1 (PLK1) as a positive effector of HBV replication.

SIRT1/HSF1/HSP pathway is essential for exenatide‐alleviated, lipid‐induced hepatic endoplasmic reticulum stress

Xiaobin Zheng, Fen Xu, Hua Liang, Huanyi Cao, Mengyin Cai, Wen Xu, Jianping Weng – 25 April 2017 – Recent studies have indicated that lipid‐induced endoplasmic reticulum (ER) stress is a major contributor to the progression of hepatic steatosis. Exenatide (exendin‐4), a glucagon‐like peptide‐1 receptor agonist, is known to improve hepatic steatosis, with accumulating evidence. In this study, we investigated whether exenatide could alleviate lipid‐induced hepatic ER stress through mammal sirtuin 1 (SIRT1) and illustrated the detailed mechanisms.

Protein disulfide isomerase inhibition synergistically enhances the efficacy of sorafenib for hepatocellular carcinoma

Jae‐Kyung Won, Su Jong Yu, Chae Young Hwang, Sung‐Hwan Cho, Sang‐Min Park, Kwangsoo Kim, Won‐Mook Choi, Hyeki Cho, Eun Ju Cho, Jeong‐Hoon Lee, Kyung Bun Lee, Yoon Jun Kim, Kyung‐Suk Suh, Ja‐June Jang, Chung Yong Kim, Jung‐Hwan Yoon, Kwang‐Hyun Cho – 25 April 2017 – Sorafenib is the only approved targeted drug for hepatocellular carcinoma (HCC), but its effect on patients' survival gain is limited and varies over a wide range depending on pathogenetic conditions.

Sirtuin 3 acts as a negative regulator of autophagy dictating hepatocyte susceptibility to lipotoxicity

Songtao Li, Xiaobing Dou, Hua Ning, Qing Song, Wei Wei, Ximei Zhang, Chen Shen, Jiaxin Li, Changhao Sun, Zhenyuan Song – 24 April 2017 – Lipotoxicity induced by saturated fatty acids (SFAs) plays a central role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD); however, the exact mechanisms remain to be fully elucidated. Sirtuin 3 (SIRT3) is a nicotinamide adenine dinucleotide–dependent deacetylase located primarily inside mitochondria.
