Endogenous signal transducer and activator of transcription 3 is required for the protection of hepatocytes against warm ischemia/reperfusion injury

Lucy Xi Lou, Tadahiro Uemura, Haresh Mani, Chen Yang, Weiyi Li, Zakiyah Kadry, Samuel Shao‐Min Zhang – 9 July 2013 – Warm ischemia/reperfusion (I/R) is a common clinical problem during liver transplantation and liver resection. Warm ischemia also occurs during trauma and shock. However, there is still no safe and promising strategy for protecting the liver from I/R injury. Signal transducer and activator of transcription 3 (STAT3) is a major immediate response molecule for protecting cell survival.

Segment 4 architecture and proposed parenchyma‐wise technique for Ex vivo graft procurement and implantation

Ramadan M. Gharbawy, Bakr M. Nour – 9 July 2013 – A parenchyma‐wise technique for the ex vivo procurement of segment 4 (S4) grafts, based on the detailed architecture of the segment, is proposed. Eighteen normal, fresh livers from adult cadavers were injected differentially with colored latex; dissection casts were prepared; and the intricate architecture of S4 was studied.

The insulin receptor translocates to the nucleus to regulate cell proliferation in liver

Maria J. Amaya, André G. Oliveira, Erika S. Guimarães, Marisa C.F. Casteluber, Sandhra M. Carvalho, Lidia M. Andrade, Mauro C.X. Pinto, Albert Mennone, Cleida A. Oliveira, Rodrigo R. Resende, Gustavo B. Menezes, Michael H. Nathanson, M. Fatima Leite – 9 July 2013 – Insulin's metabolic effects in the liver are widely appreciated, but insulin's ability to act as a hepatic mitogen is less well understood.

Organized proteomic heterogeneity in colorectal cancer liver metastases and implications for therapies

Andrei Turtoi, Arnaud Blomme, Delphine Debois, Joan Somja, David Delvaux, Georgios Patsos, Emmanuel Valentin, Olivier Peulen, Eugène Nzaramba Mutijima, Edwin Pauw, Philippe Delvenne, Olivier Detry, Vincent Castronovo – 6 July 2013 – Tumor heterogeneity is a major obstacle for developing effective anticancer treatments. Recent studies have pointed to large stochastic genetic heterogeneity within cancer lesions, where no pattern seems to exist that would enable a more structured targeted therapy approach.

Hepatic cannabinoid‐1 receptors mediate diet‐induced insulin resistance by increasing de novo synthesis of long‐chain ceramides

Resat Cinar, Grzegorz Godlewski, Jie Liu, Joseph Tam, Tony Jourdan, Bani Mukhopadhyay, Judith Harvey‐White, George Kunos – 6 July 2013 – Obesity is associated with increased activity of two lipid signaling systems (endocannabinoids [ECs] and ceramides), with both being implicated in insulin resistance. Cannabinoid‐1 receptor (CB1R) antagonists reverse obesity and insulin resistance, but have psychiatric side effects.

Free cholesterol accumulation in hepatic stellate cells: Mechanism of liver fibrosis aggravation in nonalcoholic steatohepatitis in mice

Kengo Tomita, Toshiaki Teratani, Takahiro Suzuki, Motonori Shimizu, Hirokazu Sato, Kazuyuki Narimatsu, Yoshikiyo Okada, Chie Kurihara, Rie Irie, Hirokazu Yokoyama, Katsuyoshi Shimamura, Shingo Usui, Hirotoshi Ebinuma, Hidetsugu Saito, Chikako Watanabe, Shunsuke Komoto, Atsushi Kawaguchi, Shigeaki Nagao, Kazuo Sugiyama, Ryota Hokari, Takanori Kanai, Soichiro Miura, Toshifumi Hibi – 6 July 2013 – Although nonalcoholic steatohepatitis (NASH) is associated with hypercholesterolemia, the underlying mechanisms of this association have not been clarified.
