Abstract:
Elevated expression of Yes-associated protein (YAP1) is associated with ovarian cancer. Bioinformatics analysis showed a relationship between miR-194 and YAP1. Our study intends to assess whether miR-194 regulates YAP1 expression and affects the proliferation of ovarian cancer cells and CDDP resistance. CDDP-resistant cell line A2780/CDDP was established and the expression of miR-194 and YAP1 in parental A2780 cells and normal ovarian epithelial IOSE80 cells were compared. A2780/CDDP cells were separated into miR-NC group and miR-194 mimic group followed by analysis of miR-194 and YAP1 express

Abstract:
Purpose: The purpose of this study was to evaluate the role of miR-624-5p in ovarian cancer.Methods: MiR-624-5p expression in ovarian cancer {OC) cell lines and normal cells (NCs) was evaluated and compared the differential miR-624-5p in OC A2780 cells and cisplatin-resistant OC cell line (A2780/DDP). CCK-8 was used to evaluate changes in cell viability of the A2780 and A2780/DDP cell lines as well as silenced miR-624-5p. Western Blot examined the Stat3 and phosphorylated Pi3k. The binding between PDGFRA and miR-624-5p was predicted on Targetscan and verified through Luciferase Reporter Assay.

Abstract:
We investigated the effects of silver nanoparticle (AgNP) exposure in three ovarian cancer cell lines (A2780, SKOV3, and OVCAR3). We found that AgNPs were highly cytotoxic toward A2780 and SKOV3 cells but OVCAR3 cells were less sensitive to AgNPs. In agreement with the cytotoxicity data, AgNPs caused DNA damage in A2780 and SKOV3 cells, but not in OVCAR3 cells. A2780 and SKOV3 showed higher levels of basal reactive oxygen species (ROS) relative to OVCAR3 cells. AgNP exposure increased ROS levels in both A2780 and SKOV3 cells, but not in OVCAR3 cells. We found that the heterogeneous cytotoxicit

Abstract:
The overall five-year survival rate for late-stage patients of ovarian cancer is below 29% due to disease recurrence and drug resistance. Cancer stem cells (CSCs) are known as a major contributor to drug resistance and recurrence. Accordingly, therapies targeting ovarian CSCs are needed to overcome the limitations of present treatments. This study evaluated the effect of trimebutine maleate (TM) targeting ovarian CSCs, using A2780-SP cells acquired by a sphere culture of A2780 epithelial ovarian cancer cells. TM is indicated as a gastrointestinal motility modulator and is known to as a periphe

Abstract:
Ovarian cancer leads the worst prognosis among all types of gynecologic malignancies, and patients are often diagnosed at an advanced stage. Ovarian cancer also has a high rate of metastasis; however, the detailed mechanisms for ovarian cancer prone to metastasis remain unclear. In this study, we used continuous in vitro screening of the human ovarian cancer A2780 cell line to establish a cell line (A2780-M) which shows high invasiveness and motility. Compared to the parental cells, A2780-M cells express elevated protein levels of CD44, CD133, CD34, andβ-catenin. A2780-M cells are also more re

We found that gukulenin A suppressed tumor growth in A2780-bearing mice. Gukulenin A markedly inhibited cell viability in four ovarian cancer cell lines, including the A2780 cell line.

A Cisplatin-resistant subline of a Human Ovarian cancer cell line, A2780 CP also exhibits cross resistance to 60Co gamma-radiation. Cellular Glutathione (GSH) levels were measured by the Tietze Spectrophotometric method. GSH levels in A2780 CP cells were approximately three time that of the parental A2780 cells. In cells depleted of GSH by L-Buthionine Sulfoximine (BSO), Cisplatin-resistance was significantly decreased in both cell lines. BSO had no effect on the radiation resistance of either cell lines.

Abstract:
Inappropriate stimulation of mast cells can trigger allergies including asthma, allergic rhinitis and eczema which, combined, affect almost 30% of the population in western societies. Mast cell activation begins with aggregation of IgE receptors in response to antigen. This then triggers a series of reactions resulting in the tyrosine phosphorylation of Syk kinase, PKC activation and ultimately both degranulation and secretion of leukotrienes and cytokines. CRAC channels are expressed on mast cells, and are essential for IgE-mediated mast cell activation. Previous work in our laboratory has sh
