Johann Guillemot, Maryssa Canuel, Rachid Essalmani, Annik Prat, Nabil G. Seidah – 6 February 2013 – The first seven members of the proprotein convertase (PC) family activate protein precursors by cleavage after basic residues. While PC7 has no known specific substrates, it shows redundancy with other PCs. A genome‐wide association study suggested that circulating levels of shed human transferrin receptor 1 (hTfR1) are regulated by PC7. We thus examined whether hTfR1 constitutes a specific substrate for PC7.

Xi‐Dai Long, Jin‐Guang Yao, Zhi Zeng, Yun Ma, Xiao‐Ying Huang, Zhong‐Hua Wei, Min Liu, Jian‐Jun Zhang, Feng Xue, Bo Zhai, Qiang Xia – 6 February 2013 – X‐ray repair complementing group 4 (XRCC4) is very important in maintaining overall genome stability and may play an important role in carcinogenesis. We aimed to investigate the role of polymorphisms in the coding region of this gene in hepatocellular carcinoma (HCC) caused by aflatoxin B1 (AFB1).

Han Han, Dan Sun, Wenjuan Li, Hongxing Shen, Yahui Zhu, Chen Li, Yuxing Chen, Longfeng Lu, Wenhua Li, Jinxiang Zhang, Yuan Tian, Youjun Li – 6 February 2013 – c‐Myc (Myc) plays an important role in normal liver development and tumorigenesis. We show here that Myc is pathologically activated in and essential for promoting human hepatocellular carcinoma (HCC). Myc induces HCC through a novel, microRNA (miRNA)‐mediated feedback loop comprised of miR‐148a‐5p, miR‐363‐3p, and ubiquitin‐specific protease 28 (USP28).

Miriam B. Vos, Joel E. Lavine – 6 February 2013 – Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in adults and children. A number of genetic and environmental factors are known to predispose individuals to NAFLD. Certain dietary sugars, particularly fructose, are suspected to contribute to the development of NAFLD and its progression. The increasing quantity of fructose in the diet comes from sugar additives (most commonly sucrose and high fructose corn syrup) in beverages and processed foods.

Yun‐Yong Park, Sang‐Bae Kim, Hee Dong Han, Bo Hwa Sohn, Ji Hoon Kim, Jiyong Liang, Yiling Lu, Cristian Rodriguez‐Aguayo, Gabriel Lopez‐Berestein, Gordon B. Mills, Anil K. Sood, Ju‐Seog Lee – 6 February 2013 – Metabolic changes are common features of many cancer cells and are frequently associated with the clinical outcome of patients with various cancers, including hepatocellular carcinoma (HCC). Thus, aberrant metabolic pathways in cancer cells are attractive targets for cancer therapy.

R. Todd Stravitz, Regina Bowling, Robert L. Bradford, Nigel S. Key, Sam Glover, Leroy R. Thacker, Don A. Gabriel – 6 February 2013 – Microparticles (MPs), membrane fragments of 0.1‐1.0 μm, are derived from many cell types in response to systemic inflammation. Acute liver failure (ALF) is a prototypical syndrome of systemic inflammatory response syndrome (SIRS) associated with a procoagulant state. We hypothesized that patients with ALF develop increased procoagulant MPs in proportion to the severity of systemic complications and adverse outcome.
