MicroRNA‐191 acts as a tumor promoter by modulating the TET1–p53 pathway in intrahepatic cholangiocarcinoma

Hao Li, Zun‐Qiang Zhou, Zhang‐Ru Yang, Da‐Nian Tong, Jiao Guan, Bao‐Jie Shi, Jia Nie, Xian‐Ting Ding, Bin Li, Guang‐Wen Zhou, Zheng‐Yun Zhang – 14 February 2017 – Current treatment of intrahepatic cholangiocarcinoma (ICC) remains ineffective because knowledge of ICC carcinogenesis is unclear. Increasing evidence suggests that microRNAs (miRNAs), including miR‐191, play an important role in tumorigenesis; but expression and biological functions of miR‐191 in ICC remain to be established. This study investigated the functions and underlying mechanisms of miR‐191 in ICC.

Left ventricular systolic function is associated with sympathetic nervous activity and markers of inflammation in cirrhosis

Raquel Yotti, Cristina Ripoll, Yolanda Benito, Maria Vega Catalina, Jaime Elízaga, Diego Rincón, Francisco Fernández‐Avilés, Javier Bermejo, Rafael Bañares – 13 February 2017 – An accurate evaluation of cardiac function in patients with cirrhosis remains a challenge. We used robust echocardiographic indices to characterize left ventricular (LV) systolic function and its relationship to activation of the sympathetic nervous system and inflammation in 59 patients with cirrhosis and 59 age‐matched controls.

Liver fibrosis scores predict liver disease mortality in the United States population

Aynur Unalp‐Arida, Constance E. Ruhl – 13 February 2017 – Fatty liver disease is common in the United States and worldwide due to changing lifestyles and can progress to fibrosis and cirrhosis contributing to premature death. We examined whether liver fibrosis scores were associated with increased overall and disease‐specific mortality in a United States population–based prospective survey with up to 23 years of linked‐mortality data. Data were analyzed from 14,841 viral hepatitis–negative adult participants in the third National Health and Nutrition Examination Survey, 1988‐1994.

Ammonia lowering reverses sarcopenia of cirrhosis by restoring skeletal muscle proteostasis

Avinash Kumar, Gangarao Davuluri, Rafaella Nascimento e Silva, Marielle P.K.J. Engelen, Gabrie A.M. Ten Have, Richard Prayson, Nicolaas E.P. Deutz, Srinivasan Dasarathy – 13 February 2017 – Sarcopenia or skeletal muscle loss is a frequent, potentially reversible complication in cirrhosis that adversely affects clinical outcomes. Hyperammonemia is a consistent abnormality in cirrhosis that results in impaired skeletal muscle protein synthesis and breakdown (proteostasis).
