Anti-angiogenic activity of curcumin and effects of curcumin on angiogenic biomarkers, cycloxygenase (COX)-2 and vascular endothelial growth factor (VEGF) levels were investigated. One day after hepatocellular carcinoma cell (HepG2) cells (30 microl of 2 x 10(6) cells) were inoculated onto the upper layer of the skin-fold chamber (HepG2-group, n = 15),(More)
Antiangiogenic activity of curcumin on the tumor neogenesis was investigated by evaluating the density of neocapillaries induced by Hepatocellular carcinoma cells (HepG2) in mice, using intravital fluorescence videomicroscopy. Male BALB/c nude mice (20-25 g) were used, and a dorsal skin-fold chamber was implanted. HepG2 (30 microl of 2 x 10(6) cells) were(More)
The loss of cytochrome P450 (CYP) -dependent activity continues to be a problem in the use of cultured hepatocytes in xenobiotic toxicity studies. It has been reported that the inclusion of pyruvate and various hormones in the culture medium improves the maintenance of various hepatic functions, including that of CYP2C11 mRNA expression. We have studied(More)
Tumor angiogenesis is an important process for several kinds of tumor, especially, during its angiogenic switch. The present study was aimed to investigate the dynamical process of tumor neocapillarization in Hepatocellular carcinoma cells implanted nude mice model. Male BALB/c nude mice (20-25 g) were used. After the implantation of a dorsal skin-fold(More)
