SPARC (secreted protein, acidic and rich in cysteine)--also known as osteonectin, BM-40, and 43K glycoprotein--is secreted by endothelial cells and fibroblasts in response to culture shock. SPARC has been found in association with tissues undergoing cell proliferation, migration, and extracellular matrix remodeling. We demonstrate that normal livers from(More)
BACKGROUND/AIMS The immunosuppressant FK506 is undergoing clinical trials in transplantation and autoimmune diseases. FK506 modulates several cytokines and exerts hepatoprotection in acute models. This study was initiated to determine whether FK506 would be beneficial as an antifibrogenic agent. METHODS Fibrosis was induced by carbon tetrachloride(More)
Fibronectin expression is of considerable importance in normal and fibrotic liver. Plasma fibronectin levels are correlated with good prognosis in liver failure, and cellular fibronectin plays a crucial role in fibrogenesis. In this study, we observed that the H4II rat hepatoma cell line does not express fibronectin. Furthermore, a recombinant vector (pFGH)(More)
TA1, a novel rat oncofetal cDNA, is the predicted homolog of the human lymphocyte activation gene E16. The encoded peptides share high homology with transport-associated and uncharacterized sequences in distant species, suggesting an important and conserved function in cellular homeostasis. Moderate steady-state levels of TA1 RNA were induced following(More)
The tyrosine kinase inhibitor imatinib is successfully used in the treatment of chronic myeloid leukemia, but the occurrence of resistance phenomena can significantly limit therapeutic impact. Imatinib shows synergistic effects with cisplatin, suggesting that the coadministration of different cytostatics might reestablish the efficacy of treatment. We(More)
