MicroRNA‐206 prevents the pathogenesis of hepatocellular carcinoma by modulating expression of met proto‐oncogene and cyclin‐dependent kinase 6 in mice

Heng Wu, Junyan Tao, Xiaolei Li, Tianpeng Zhang, Lei Zhao, Yao Wang, Lei Zhang, Jun Xiong, Zhi Zeng, Na Zhan, Clifford J. Steer, Li Che, Mingjie Dong, Xiaomei Wang, Junqi Niu, Zhuoyu Li, Guiqing Yan, Xin Chen, Guisheng Song – 17 July 2017 – Hepatocellular carcinoma (HCC) is one of the most lethal cancers worldwide, and therapeutic agents for this malignancy are lacking. MicroRNAs play critical roles in carcinogenesis and present tremendous therapeutic potential.

USP18 protects against hepatic steatosis and insulin resistance through its deubiquitinating activity

Shimin An, Ling‐Ping Zhao, Li‐Jun Shen, Siyuan Wang, Kuo Zhang, Yu Qi, Jilin Zheng, Xiao‐Jing Zhang, Xue‐Yong Zhu, Rong Bao, Ling Yang, Yue‐Xin Lu, Zhi‐Gang She, Yi‐Da Tang – 17 July 2017 – Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis, impaired insulin sensitivity, and chronic low‐grade inflammation. However, the pathogenic mechanism of NAFLD is poorly understood, which hinders the exploration of possible treatments.

Ribavirin suppresses hepatic lipogenesis through inosine monophosphate dehydrogenase inhibition: Involvement of adenosine monophosphate‐activated protein kinase‐related kinases and retinoid X receptor α

Shinya Satoh, Kyoko Mori, Daichi Onomura, Youki Ueda, Hiromichi Dansako, Masao Honda, Shuichi Kaneko, Masanori Ikeda, Nobuyuki Kato – 13 July 2017 – Ribavirin (RBV) has been widely used as an antiviral reagent, specifically for patients with chronic hepatitis C. We previously demonstrated that adenosine kinase, which monophosphorylates RBV into the metabolically active form, is a key determinant for RBV sensitivity against hepatitis C virus RNA replication. However, the precise mechanism of RBV action and whether RBV affects cellular metabolism remain unclear.

Increased ethanol‐inducible cytochrome P450‐2E1 and cytochrome P450 isoforms in exosomes of alcohol‐exposed rodents and patients with alcoholism through oxidative and endoplasmic reticulum stress

Young‐Eun Cho, Esteban Mezey, James P. Hardwick, Norman Salem, Dahn L. Clemens, Byoung‐Joon Song – 13 July 2017 – This study investigated the role of ethanol‐inducible cytochrome P450‐2E1 (CYP2E1) in enhancing CYP2E1 and other P450 proteins in extracellular vesicles (EVs) from alcohol‐exposed rodents and human patients with alcoholism and their effects on oxidative hepatocyte injury. Female Fischer rats and wild‐type or Cyp2e1‐null mice were exposed to three oral doses of binge ethanol or dextrose control at 12‐hour intervals.

Iron‐related markers are associated with infection after liver transplantation

Jennifer K. L. Chow, Tomas Ganz, Robin Ruthazer, Mary Ann Simpson, Elizabeth A. Pomfret, Fredric D. Gordon, Mark E. Westerman, David R. Snydman – 13 July 2017 – Though serum iron has been known to be associated with an increased risk of infection, hepcidin, the major regulator of iron metabolism, has never been systematically explored in this setting. Finding early biomarkers of infection, such as hepcidin, could help identify patients in whom early empiric antimicrobial therapy would be beneficial.
