The epidermal growth factor receptor ligand amphiregulin participates in the development of mouse liver fibrosis

Maria J. Perugorria, M. Ujue Latasa, Alexandra Nicou, Hugo Cartagena‐Lirola, Josefa Castillo, Saioa Goñi, Umberto Vespasiani‐Gentilucci, Maria G. Zagami, Sophie Lotersztajn, Jesús Prieto, Carmen Berasain, Matias A. Avila – 26 September 2008 – The hepatic wound‐healing response to chronic noxious stimuli may lead to liver fibrosis, a condition characterized by excessive deposition of extracellular matrix. Fibrogenic cells, including hepatic stellate cells and myofibroblasts, are activated in response to a variety of cytokines, growth factors, and inflammatory mediators.

Altered hepatic triglyceride content after partial hepatectomy without impaired liver regeneration in multiple murine genetic models

Elizabeth P. Newberry, Susan M. Kennedy, Yan Xie, Jianyang Luo, Susan E. Stanley, Clay F. Semenkovich, Roseanne M. Crooke, Mark J. Graham, Nicholas O. Davidson – 26 September 2008 – Liver regeneration is impaired following partial hepatectomy (PH) in mice with genetic obesity and hepatic steatosis and also in wild‐type mice fed a high‐fat diet. These findings contrast with other data showing that liver regeneration is impaired in mice in which hepatic lipid accumulation is suppressed by either pharmacologic leptin administration or by disrupted glucocorticoid signaling.

Hepatocellular cancer arises from loss of transforming growth factor beta signaling adaptor protein embryonic liver fodrin through abnormal angiogenesis

Hye Jung Baek, Sung Chul Lim, Krit Kitisin, Wilma Jogunoori, Yi Tang, M. Blair Marshall, Bibhuti Mishra, Tae Hyun Kim, Kwan Ho Cho, Sang Soo Kim, Lopa Mishra – 26 September 2008 – We have previously demonstrated that 40%‐70% of elf+/− mice spontaneously develop hepatocellular cancer (HCC) within 15 months, revealing the importance of the transforming growth factor‐beta (TGF‐β) signaling pathway in suppressing tumorigenesis in the liver.
