there is a continuing need to identify new agents that are active in ovarian cancer. etoposide is a derivative of the plant alkaloid epipodophyllotoxin. the availability of etoposide in oral preparation allows prolonged administration by the oral route. in this study, activity and toxicity of etoposide in women with recurrent ovarian cancer are described from a case series of women with recurre...

PURPOSE The metabolism of cancerous cells is in many ways different than in healthy cells. In ovarian cancer, cells exhibit activity of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), which participate in metabolism of many biological substances. The aim of this study was to compare the metabolism of ovarian cancer cells, ovarian cysts and normal ovarian cells by measurement of A...

objective: this study aimed to evaluate the incidence of apoptosis in vitrified and non-vitrified human ovarian tissue by the use of morphological analysis and apoptosis assay techniques. methods: we obtained human ovarian tissue biopsies from 30 women who underwent elective caesarean sections. tissues were transported to the laboratory in pre-warmed, equilibrated leibovitz l-15 medium within 2...

background: aqueous extract of winter cherry ( physalis alkekengi l; family of solanaceae) fruits (wcf) has long been recommended for fertility control by herbalists in iran. the effect of this extract on lowering serum progesterone levels has been reported previously.   objective: to study the effects of wcf extract on the activities of ovarian 3β-hydroxysteroid dehydrogenase (3β-hsd) responsi...

Background: Aqueous extract of winter cherry (Physalis alkekengi L; family of Solanaceae) fruits (WCF) has long been recommended for fertility control by herbalists in Iran. The effect of this extract on lowering serum progesterone levels has been reported previously. Objective: To study the effects of WCF extract on the activities of ovarian 3β-hydroxysteroid dehydrogenase (3β-HSD) responsible...

Background: It seems that Vinca. herbacea has an anti-tumor effect. Here, the immunotherapeutic effect of this compound is assessed against human ovarian cancer (SKOV3) cells because of the high incidence of this tumor in women. Materials and Methods: The cytotoxic activity of V. herbacea extract against human ovarian cancer (SKOV3) cells was determined by MTT assay. The apoptosis-inducing pote...

Objective: Aldehyde dehydrogenase (ALDH) enzymatic activity identifies ovarian cancer stem-like cells. We investigated the antineoplastic activity of the ALDH inhibitor Disulfiram on bulk ovarian cancer cells and CD133+/ALDH+ cancer stem-like cells. Study Design: Ovarian cancer cell lines, human ovarian surface epithelial cells, and mesenchymal stem cells were treated with increasing concentrat...

Epithelial ovarian cancer (EOC) is the leading cause of death for gynecological cancer. Most patients are not diagnosed until the cancer is at an advanced stage with poor prognosis. Notch1 signaling pathway plays an oncogenic role in EOC. There have been few studies on enzymatic activity of γ-secretase and the mechanism of how γ-secretase inhibitor works on cancer cell. Here, we show that Jagge...
