Objectives Ovarian cancer is one of the most lethal malignant tumors in women. Secreted phosphoprotein 1 (SPP1) plays an important role in some cancer types. Therefore, the role of SPP1 in ovarian cancer was determined and the potential mechanism was elucidated. Materials and methods The expression of SPP1 in ovarian cancer was determined by immunohistochemistry in ovarian cancer tissues and ...

Delphinidin is a member of the anthocyanidin family and is a natural pigment in red cabbage, berries, sweet potatoes and grapes. It possesses nutraceutical properties against various chronic diseases and types of cancer. However, little is known about its preventative effects on epithelial ovarian cancer, a disease that is associated with a low survival rate, a poor prognosis and a high rate of...

One emerging model for the development of drug-resistant tumors utilizes a pool of self-renewing malignant progenitors known as cancer stem cells (CSCs) or cancer-initiating cells (CICs). The purpose of this study was to propagate such CICs from the ovarian cancer cell line SKOV3. The SKOV3 sphere cells were selected using 40.0 micromol/l cisplatin and 10.0 micromol/l paclitaxel in serum-free c...

A large quantity of M2-polarized tumor-associated macrophages (TAMs) is present in the tissue, ascitic fluid and peritoneum of ovarian cancer patients. A thorough understanding of the roles of M2-TAM in the development of ovarian cancer may provide new insight into the treatment of this disease. The rapid advancement of omics techniques presents a great challenge to biologists to extract meanin...

Abstract This study evaluated the biological fabrication and characterization of zinc oxide nanoparticles (ZnONPs) using Nepeta cataria (NC) their anticancer activity against ovarian cancer cells (SKOV3). synthesized ZnONPs leaf extract N. through a method. The particles were characterized in several ways such as zeta potential, ultraviolet-visible (UV-Vis) spectrum, Fourier transform infrared ...

Hax-1 is a multifunctional protein, which is involved in diverse cellular signaling pathways including tumor cell survival and migration. We have shown previously that cell migration stimulated by the oncogenic G protein, G13, requires Hax-1 for the formation of a functional complex involving Gα13, Rac1, and cortactin. However, the role of Hax-1 in cancer cell migration or its role in Rac1-cort...

BACKGROUND Cationic polymers have been accepted as effective nonviral vectors for gene delivery with low immunogenicity unlike viral vectors. However, the lack of organ or cell specificity sometimes hampers their application and the modification of polymeric vectors has also shown successful improvements in achieving cell-specific targeting delivery and in promoting intracellular gene transfer ...

Caveolin-1 (Cav-1), a family of ubiquitously expressed oligomeric structural proteins in many mammalian cells, has been shown to be an effective regulator of tumorigenesis. Recent studies have indicated that Cav-1 can promote resistance to chemotherapy in a variety of tumors. However, the regulation of Cav-1 on chemoresistance in ovarian cancer is still unknown. In the present study, the mRNA a...

PURPOSE Stress has long been believed to influence carcinogenesis, but little is known about physiological mechanisms that may underlie these effects. We have recently observed lower levels of vascular endothelial growth factor (VEGF) in ovarian cancer patients with greater social support, whereas higher VEGF was found in patients with greater distress. The goal of this study was to examine pos...

Ovarian cancer is a highly prevalent cancer among women. Recent studies have indicated that microRNAs (miRs) may serve important roles in the pathogenesis of ovarian cancer. miR-519a was observed to be downregulated in tissue samples of patients with ovarian cancer; however, its role in ovarian cancer requires further investigation. The aim of the present study was to examine the role of miR-51...
