The biologic effects of growth factors are dependent on cell adhesion, and a cross talk occurs between growth factors and adhesion complexes. The aim of the present study was to evaluate the influence of cell adhesion on the major intracellular signaling pathways elicited by platelet-derived growth factor (PDGF) in hepatic stellate cells (HSC). PDGF(More)
AIM To investigate the effects of troglitazone (TGZ), an anti-diabetic drug which activates peroxisome proliferator-activated receptor-gamma (PPAR-gamma), for liver tissue repair, and the development of ductular reaction, following common bile duct ligation (BDL) in rats. METHODS Rats were supplemented with TGZ (0.2% w/w in the pelleted food) for 1 wk(More)
Myristoylated alanine-rich protein kinase c substrate (MARCKS) has been suggested to be implicated in cell adhesion, secretion, motility and mitogenesis through regulation of the actin cytoskeletal structure. In the present study, a possible link between MARCKS and the platelet-derived growth factor (PDGF) signaling pathway was investigated in activated(More)
BACKGROUND Human hepatic stellate cells have been shown to be resistant to apoptotic stimuli. This is likely dependent on the activation of anti-apoptotic pathways upon transition of these cells to myofibroblast-like cells. In particular, previous studies have demonstrated an increased expression of the anti-apoptotic protein Bcl-2 and a decreased(More)
