Human testisin, a serine protease, is highly expressed in ovarian cancer and premeiotic spermatocytes with relatively little expression in other normal tissues. We first showed that testisin was localized on the surface of cultured tumor cells as a glycosyl-phosphatidylinositol-linked protein. We next explored the biological function of testisin in malignant transformation through manipulation ...

We examined the production and utilization of interleukin 6 (IL-6), a multifunctional cytokine with diverse biological effects, by both ovarian cancer cell lines and primary ovarian tumor cultures. We have found that epithelial ovarian cancer cell lines (CAOV-3, OVCAR-3, and SKOV-3) constitutively produce varying amounts of IL-6. This molecule is biologically active as determined by the prolife...

background: chemo-immunotherapy is one of the new achievements for treatment of cancer, by which the success of anti-cancer therapy can be increased. in vitro studies have been shown that arteether (are) induces apoptosis in tumor cells, but not in normal cells. objective: to investigate the cytotoxic and immunomodulatory properties of arteether in-vivo and in-vitro. methods: in this study, we ...

Vasohibin-1 (VASH1) is a negative feedback regulator of angiogenesis, the first to be discovered, and was identified in vascular endothelial growth factor (VEGF)-stimulated vascular endothelial cells. Vasohibin-1 inhibits abnormal vascularization induced by various angiogenic factors including fibroblast growth factor and platelet-derived growth factor (PDGF), in addition to VEGF. By focusing o...

BACKGROUND Ovarian adenocarcinoma is not generally discovered in patients until there has been widespread intraperitoneal dissemination, which is why ovarian cancer is the deadliest gynecologic malignancy. Though incompletely understood, the mechanism of peritoneal metastasis relies on primary tumor cells being able to detach themselves from the tumor, escape normal apoptotic pathways while fre...

background: gbm is the most common and malignant astrocity tumor and it is persistent to common treatment so, these patients have a very low survival. several researchers around the world, including iran, have been investigated gbm-cell line in vitro. however in vivo studies have not been fulfilled. methods : as standard cell line (u-87mg) derived from human gbm and total gbm tumor derived from...

Ovarian cancer causes more deaths than any other cancer of the female reproductive system. The vitamin D receptor (VDR) is weakly to moderately expressed in normal ovarian cell, but is more strongly expressed in ovarian cancer line and tumor tissue. In vitro studies have reported that vitamin D administration inhibits cell growth and induces apoptosis in a dose dependent manner in both animal a...

PURPOSE We looked at the value of three preclinical cancer models, the in vitro human cell line, the human xenograft, and the murine allograft, to examine whether they are reliable in predicting clinical utility. EXPERIMENTAL DESIGN Thirty-one cytotoxic cancer drugs were selected. Literature was searched for drug activity in Phase II trials, human xenograft, and mouse allografts in breast, no...

Previous studies have demonstrated that the presence of Hox transcript antisense intergenic RNA (HOTAIR) is correlated with poor survival in several types of cancer, including breast cancer, and promotes tumor metastasis. Currently, little is known regarding the correlation between HOTAIR and chemoresistance in cancer. The current study aimed to investigate the role of HOTAIR in epithelial ovar...

Ovarian carcinoma is one of the most common and lethal malignancies in the world. Replication factor C (RFC) plays an important role in DNA replication, DNA damage repair, and checkpoint control during cell cycle progression in all eukaryotes. Our previous study found that one unit of RFC complex, RFC3, is over-expressed in ovarian tumor tissues. However, its role in the development of ovarian ...
