Variant in the glucokinase regulatory protein (GCKR) gene is associated with fatty liver in obese children and adolescents

Nicola Santoro, Clarence K. Zhang, Hongyu Zhao, Andrew J. Pakstis, Grace Kim, Romy Kursawe, Daniel J. Dykas, Allen E. Bale, Cosimo Giannini, Bridget Pierpont, Melissa M. Shaw, Leif Groop, Sonia Caprio – 22 November 2011 – Recently, the single nucleotide polymorphism (SNP) identified as rs1260326, in the glucokinase regulatory protein (GCKR), was associated with hypertriglyceridemia in adults.

Interleukin‐30: A novel antiinflammatory cytokine candidate for prevention and treatment of inflammatory cytokine‐induced liver injury

Denada Dibra, Jeffry Cutrera, Xueqing Xia, Bhaskar Kallakury, Lopa Mishra, Shulin Li – 22 November 2011 – The liver is the major metabolic organ and is subjected to constant attacks from chronic viral infection, uptake of therapeutic drugs, life behavior (alcoholic), and environmental contaminants, all of which result in chronic inflammation, fibrosis, and, ultimately, cancer. Therefore, there is an urgent need to discover effective therapeutic agents for the prevention and treatment of liver injury, the ideal drug being a naturally occurring biological inhibitor.

Thrombospondin‐1 is a novel negative regulator of liver regeneration after partial hepatectomy through transforming growth factor‐beta1 activation in mice

Hiromitsu Hayashi, Keiko Sakai, Hideo Baba, Takao Sakai – 22 November 2011 – The matricellular protein, thrombospondin‐1 (TSP‐1), is prominently expressed during tissue repair. TSP‐1 binds to matrix components, proteases, cytokines, and growth factors and activates intracellular signals through its multiple domains. TSP‐1 converts latent transforming growth factor‐beta1 (TGF‐β1) complexes into their biologically active form. TGF‐β plays significant roles in cell‐cycle regulation, modulation of differentiation, and induction of apoptosis.

Caveolin‐1 orchestrates the balance between glucose and lipid‐dependent energy metabolism: Implications for liver regeneration

Manuel Alejandro Fernández‐Rojo, Christina Restall, Charles Ferguson, Nick Martel, Sally Martin, Marta Bosch, Adam Kassan, Gary M. Leong, Sheree D. Martin, Sean L. McGee, George E.O. Muscat, Robin L. Anderson, Carlos Enrich, Albert Pol, Robert G. Parton – 22 November 2011 – Caveolin‐1 (CAV1) is a structural protein of caveolae involved in lipid homeostasis and endocytosis.

Protease‐activated receptor 2 promotes experimental liver fibrosis in mice and activates human hepatic stellate cells

Virginia Knight, Jorge Tchongue, Dinushka Lourensz, Peter Tipping, William Sievert – 16 November 2011 – Protease‐activated receptor (PAR) 2 is a G‐protein–coupled receptor that is activated after proteolytic cleavage by serine proteases, including mast cell tryptase and activated coagulation factors. PAR‐2 activation augments inflammatory and profibrotic pathways through the induction of genes encoding proinflammatory cytokines and extracellular matrix proteins. Thus, PAR‐2 represents an important interface linking coagulation and inflammation.

Homozygosity mapping identifies a bile acid biosynthetic defect in an adult with cirrhosis of unknown etiology

Vered Molho‐Pessach, Jonathan J. Rios, Chao Xing, Kenneth D.R. Setchell, Jonathan C. Cohen, Helen H. Hobbs – 16 November 2011 – The most common inborn error of bile acid metabolism is 3β‐hydroxy‐Δ5‐C27‐steroid oxidoreductase (3β‐HSD) deficiency, a disorder that usually presents in early childhood with hepatic dysfunction. Timely diagnosis of this disorder is crucial because it can be effectively treated with primary bile acid replacement. Here we describe a 24‐year‐old woman from Iran with cirrhosis of unknown etiology.

Family history of liver cancer and hepatocellular carcinoma

Federica Turati, Valeria Edefonti, Renato Talamini, Monica Ferraroni, Matteo Malvezzi, Francesca Bravi, Silvia Franceschi, Maurizio Montella, Jerry Polesel, Antonella Zucchetto, Carlo La Vecchia, Eva Negri, Adriano Decarli – 16 November 2011 – Familial clustering of hepatocellular carcinoma (HCC) has been frequently reported in eastern Asiatic countries, where hepatitis B infection is common. Little is known about the relationship between family history of liver cancer and HCC in Western populations.
