Sanyal, Dae Joong Kang, Masoumeh Sikaroodi, Patrick M Gillevet – 29 March 2015 – Altered gut microbiome is associated with systemic inflammation and cirrhosis decompensation. However, the correlation of the oral microbiome with inflammation in cirrhosis is unclear. Our aim was to evaluate the oral microbiome in cirrhosis and compare with stool microbiome.

Kuang‐Hsiang Chuang, Christa L. Whitney‐Miller, Chin‐Yi Chu, Zhongren Zhou, M. Katherine Dokus, Shannon Schmit, Christopher T. Barry – 29 March 2015 – Vascular invasion provides a direct route for tumor metastasis. The degree to which microRNA (miRNA) expression plays a role in tumor vascular invasion is unclear. Here, we report that miR‐494 is up‐regulated in human hepatocellular carcinoma (HCC) tumors with vascular invasion and can promote HCC cell invasiveness by gene inactivation of multiple invasion‐suppressor miRNAs.

The transmembrane 6 superfamily member 2 (TM6SF2) gene E167K variant increases liver fat and risk of progressive steatohepatitis by interfering with lipoprotein secretion.

Sharon E. Hopcraft, Matthew J. Evans – 29 March 2015 – Hepatitis C virus (HCV) cell entry is a complex, multistep process requiring numerous host cell factors, including the tight junction protein claudin‐1 (CLDN1). It is not known whether CLDN1 and the HCV glycoproteins physically interact. Therefore, the focus of this work was to study genetic interactions between CLDN1 and HCV. We used CRISPR technology to generate CLDN1 knockout (KO) Huh‐7.5 cells, which could not be infected by genotype 2a Jc1 HCV unless CLDN1 expression was restored.
