It remains unclear whether physical activity is associated with epithelial ovarian cancer risk. We therefore examined the association between recreational physical activity and risk of ovarian cancer in a national population-based case-control study in Australia. We also systematically reviewed all the available evidence linking physical activity with ovarian cancer to provide the best summary ...
P-glycoprotein (P-gp) expression and DNA topoisomerase (Topo) II are important variables in multidrug resistant tumor cell lines. The aim of this study was to evaluate P-gp expression and Topo I and II activity in benign and malignant epithelial ovarian tumors. P-gp expression was analyzed immunohistochemically in cryostat sections of fresh tumor specimens. In the same specimens Topo I and II a...
Background & Aim: Diabetes mellitus increases oxidative stress and results in the weakening of the antioxidant defense system. Leaves of mangrove (Avicennia marina) which have not been studied enough are rich in antioxidant compounds. This study was conducted to determine the effect of aqueous extract of mangrove leaves (Avicennia marina) on the antioxidant enzyme activities of ovarian tissue i...
PURPOSE ARHI expression is lost or markedly down-regulated in the majority of ovarian cancers. The mechanism by which ARHI is down-regulated in ovarian cancers is still not clear. Our previous reports indicated that ARHI promoter activity was reduced in ovarian cancer cells, due in part to the effects of negative regulatory transcription factor(s). EXPERIMENTAL DESIGN AND RESULTS We now show ...
AIM To investigate the correlation between oncoprotein Bmi-1 and telomerase activity in ovarian cancer tissues. METHODS SP immunohistochemistry was adopted to detect the expression of Bmi-1 protein in tissues of 47 ovarian epithelial cancer cases. Modified telomeric repeat amplification protocol (TRAP, silver staining technique) was used to detect the telomerase activity. RESULTS While in 8...

Lysophosphatidic acid (LPA) mediates pleomorphic effects on multiple cell lineages, including an increased proliferative response of ovarian cancer cells both in vitro and in vivo, at least in part through the novel expression of LPA receptors. Thus, LPA hydrolysis is necessary to limit the duration of LPA's action on multiple cell types, including ovarian cancer cells. We determined the princi...
