Plasmacytoid dendritic cell‐derived IFN‐α promotes murine liver ischemia/reperfusion injury by induction of hepatocyte IRF‐1

Antonino Castellaneta, Osamu Yoshida, Shoko Kimura, Shinichiro Yokota, David A. Geller, Noriko Murase, Angus W. Thomson – 3 February 2014 – Plasmacytoid dendritic cells (pDC) constitute the body's principal source of type I interferon (IFN) and are comparatively abundant in the liver. Among various cytokines implicated in liver ischemia and reperfusion (I/R) injury, type I IFNs have been described recently as playing an essential role in its pathogenesis.

Gene expression signature for biliary atresia and a role for interleukin‐8 in pathogenesis of experimental disease

Kazuhiko Bessho, Reena Mourya, Pranavkumar Shivakumar, Stephanie Walters, John C. Magee, Marepalli Rao, Anil G. Jegga, Jorge A. Bezerra – 3 February 2014 – Biliary atresia (BA) is a progressive fibroinflammatory obstruction of extrahepatic bile ducts that presents as neonatal cholestasis. Due to the overlap in clinical, biochemical, and histological features with other causes of cholestasis, the diagnosis requires an intraoperative cholangiogram. Thus, we determined whether diseased livers express a gene expression signature unique to BA.

Long noncoding RNA in liver diseases

Kenji Takahashi, Irene Yan, Hiroaki Haga, Tushar Patel – 3 February 2014 – The identification of the presence of large RNA transcripts that do not code for proteins but that may have biological functions has provided an important new perspective in gene regulation. These long noncoding RNAs (lncRNAs) are being increasingly recognized to contribute to many biological processes through diverse mechanisms. The roles of these emerging genes are being recognized across kingdoms.
