A cell‐surface β‐hydroxylase is a biomarker and therapeutic target for hepatocellular carcinoma

Arihiro Aihara, Chiung‐Kuei Huang, Mark J. Olsen, Qiushi Lin, Waihong Chung, Qi Tang, Xiaoqun Dong, Jack R. Wands – 20 June 2014 – Hepatocellular carcinoma (HCC) has a poor prognosis as a result of widespread intra‐ and extrahepatic metastases. There is an urgent need to understand signaling cascades that promote disease progression. Aspartyl‐(asparaginyl)‐β‐hydroxylase (ASPH) is a cell‐surface enzyme that generates enhanced cell motility, migration, invasion, and metastatic spread in HCC. We hypothesize that inhibition of its enzymatic activity could have antitumor effects.

Timed regulation of P‐element‐induced wimpy testis–interacting RNA expression during rat liver regeneration

Ledda‐Columbano, Amedeo Columbano, Alessandro Weisz – 16 June 2014 – Small noncoding RNAs comprise a growing family of molecules that regulate key cellular processes, including messenger RNA (mRNA) degradation, translational repression, and transcriptional gene silencing.

Emerging roles of Notch signaling in liver disease

Fabian Geisler, Mario Strazzabosco – 16 June 2014 – This review critically discusses the most recent advances in the role of Notch signaling in liver development, homeostasis, and disease. It is now clear that the significance of Notch in determining mammalian cell fates and functions extends beyond development, and Notch is a major regular of organ homeostasis. Moreover, Notch signaling is reactivated upon injury and regulates the complex interactions between the distinct liver cell types involved in the repair process.
