2004 JUL 1 - (NewsRx.com & NewsRx.net) -- Bikunin plus paclitaxel trims tumor burden and ascites in ovarian cancer models.
According to researchers in Japan, "our previous studies of intraperitoneal ovarian carcinoma in a mouse model demonstrated that bikunin gene transfection could prevent ascites formation and intraperitoneal disseminated metastasis. Although ascites was almost completely inhibited, tumor burden was variably reduced. Several reports have indicated that bikunin may be involved in tumor survival."
"In the present study, the effectiveness of exogenous bikunin and the biodistribution characteristics of [subscript]125I-bikunin were initially examined in a mouse model of human ovarian cancer HRA cells. The once-daily i.p. administration of bikunin significantly decreased progressive growth of HRA tumors and ascites formation in a dose-dependent manner," H. Kobayashi and colleagues, Hamamatsu University, School of Medicine reported.
"Maximal radioisotope tumor uptake peaked at 7.4% injected dose/g at 3 hr. Bikunin binding specificity was demonstrated by reduced tumor uptake after coinjection of excess nonradioactive bikunin. Bikunin was rapidly excreted renally. The bikunin therapy produced the significant inhibition in expression of the proteolysis (uPA and uPAR) and angiogenesis-related molecules (vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF))."
"The second purpose of our study was to optimize the ...
