Epigenetic silence of ankyrin‐repeat–containing, SH3‐domain–containing, and proline‐rich‐region– containing protein 1 (ASPP1) and ASPP2 genes promotes tumor growth in hepatitis B virus–positive hepatocellular carcinoma

Jian Zhao, Guobin Wu, Fangfang Bu, Bin Lu, Anmin Liang, Lei Cao, Xin Tong, Xin Lu, Mengchao Wu, Yajun Guo – 23 December 2009 – The ankyrin‐repeat–containing, SH3‐domain–containing, and proline‐rich‐region–containing protein (ASPP) family of proteins regulates apoptosis through interaction with p53 and its family members. This study evaluated the epigenetic regulation of ASPP1 and ASPP2 in hepatitis B virus (HBV)‐positive hepatocellular carcinoma (HCC) and explores the effects of down‐regulation of ASPP1 and ASPP2 on the development of HCC.

Nonalcoholic fatty liver disease after liver transplantation for cryptogenic cirrhosis or nonalcoholic fatty liver disease

Kanthi Yalamanchili, Sherif Saadeh, Göran B. Klintmalm, Linda W. Jennings, Gary L. Davis – 16 December 2009 – Nonalcoholic steatohepatitis (NASH) may account for many cases of cryptogenic cirrhosis. If so, then steatosis might recur after liver transplantation. Two thousand fifty‐two patients underwent primary liver transplantation for chronic liver disease between 1986 and 2004. Serial liver biopsy samples were assessed for steatosis and fibrosis. Two hundred fifty‐seven patients (12%) had a pretransplant diagnosis of cryptogenic cirrhosis (239) or NASH (18).

Rapamycin and tacrolimus differentially modulate acute graft‐versus‐host disease in rats after liver transplantation

Guodong Xu, Linyan Wang, Wei Chen, Fei Xue, Xueli Bai, Liang Liang, Xuning Shen, Mangli Zhang, Dajing Xia, Tingbo Liang – 16 December 2009 – Acute graft‐versus‐host disease (aGVHD) is a serious complication of liver transplantation (LTx); it occurs in 1% to 2% of liver allograft recipients. The condition has a poor prognosis and poses major diagnostic and therapeutic challenges. A rat model of aGVHD after LTx has been developed, and a relative decrease in regulatory T (Treg) cells has been shown to be associated with this model.

Gender‐specific differences associated with living donor liver transplantation: A review study

Hanna C. Hermann, Burghard F. Klapp, Gerhard Danzer, Christina Papachristou – 16 December 2009 – Living donor liver transplantation (LDLT) has developed into an important therapeutic option for liver diseases. For living donor kidney transplantation (LDKT), gender‐specific differences have been observed among both donors (two‐thirds being women and one‐third being men) and recipients (two‐thirds being men and one‐third being women). The aim of this study was to determine whether there is a gender disparity for LDLT.

Modified pediatric end‐stage liver disease scoring system and pediatric liver transplantation in Brazil

Joao Seda Neto, Eduardo Carone, Renata P. S. Pugliese, Eduardo A. Fonseca, Gilda Porta, Irene Miura, Vera B. Danesi, Teresa C. Guimaraes, Andre L. Godoy, Adriana Porta, Rodrigo Vincenzi, Francisco Carnevale Filho, Mario Kondo, Paulo Chapchap – 15 December 2009 – The Pediatric End‐Stage Liver Disease (PELD) scoring system is a formula developed to provide a continuous numerical assessment of the risk of death in order to allocate livers to children in need of transplantation. The PELD scoring system was introduced in Brazil in July 2006.

The histogenesis of regenerative nodules in human liver cirrhosis

Wey‐Ran Lin, Siew‐Na Lim, Stuart A. C. McDonald, Trevor Graham, Victoria L. Wright, Claire L. Peplow, Adam Humphries, Hemant M. Kocher, Nicholas A. Wright, Amar P. Dhillon, Malcolm R. Alison – 30 November 2009 – Here, we investigate the clonality and cells of origin of regenerative nodules in human liver cirrhosis using mitochondrial DNA (mtDNA) mutations as markers of clonal expansion. Mutated cells are identified phenotypically by deficiency in the entirely mtDNA encoded cytochrome c oxidase (CCO) enzyme by histochemical and immunohistochemical methods.
