Ovarian cancer, especially epithelial ovarian cancer (EOC), which accounts for 90% of ovarian cancer, continues to be the leading cause of death among gynecological malignancies. However, the factors associated with its malignant biological behavior are still poorly understood. Accumulating evidence suggests that microRNAs (miRNAs), regulating diverse(More)
TRPC channels are Ca²⁺-permeable cationic channels controlling Ca²⁺ influx response to the activation of G protein-coupled receptors and protein tyrosine kinase pathways or the depletion of Ca²⁺ stores. Here we aimed to investigate whether TRPC can act as the potential therapeutic targets for ovarian cancer. The mRNAs of TRPC1, TRPC3, TRPC4 and TRPC6 were(More)
PURPOSE To investigate the influence of miR-21 down-regulation on cell proliferation, apoptosis, invasion and migration of ovarian papillary adenocarcinoma cell lines (OVCAR3). METHODS Short-hairpin RNA (shRNA), specifically targeting miR-21, was constructed and transfected into OVCAR3 cells using the pSIREN-RetroQ linear vector (pSIREN-miR-21). The(More)
Overwhelming evidence has demonstrated that the aberrant expression of the human trophoblast cell-surface antigen (TROP2) was associated with tumor aggressiveness and poor prognosis in a variety of human cancers, however the roles of TROP2 in cervical cancer have not been investigated. The purpose of our study was to elucidate the prognostic significance of(More)
OBJECTIVE The aims of this retrospective study by means of immunohistochemical staining were (1) to study the expression of c-ras, c-erbB-2, p53, and nm23 gene products in complete hydatidiform moles that progress to gestational trophoblastic tumor and in those that remit spontaneously after evacuation, and (2) to estimate the predictive value of the(More)
OBJECTIVE To evaluate the impact of ovarian preservation on overall survival in young women with early-stage endometrial cancer. DESIGN Retrospective and meta-analysis. SETTING Two medical centers. PATIENT(S) A total of 203 patients diagnosed with endometrial cancer (≤45 years) from 2000 until 2010. INTERVENTION(S) Patients who underwent(More)
The objective of this study was to illustrate the role of enhancer zeste homolog 2 (EZH2) overexpression in the proliferation, progression, and prognosis of cervical cancer. We detected EZH2 and Ki-67 expression levels using immunohistochemical (IHC) studies in 20 normal cervical tissues, 50 cervical intraepithelial neoplasia (including 25 low-grade(More)
The purpose of this study is to determine the methylation status of Transforming growth factor-beta-inducible gene-h3 (TGFBI) and its correlation with paclitaxel chemoresistance in ovarian cancer. The methylation status of TGFBI was examined in ovarian cancer and control groups by methylation-specific PCR (MSP) and bisulfite sequencing PCR (BSP). The TGFBI(More)
BACKGROUND Calcineurin B homologous protein isoform 2 (CHP2) was identified to be expressed in various malignant cell lines including ovarian cancer, but not in the normal tissue counterpart. The biological function of CHP2 related to cancer progression is still unknown. MATERIALS AND METHODS A CHP2-negative human epithelial ovarian cancer cell line(More)
Photothermal ablation (PTA) is a promising avenue in the area of cancer therapeutics that destroys tumor cells through conversion of near-infrared (NIR) laser light to heat. Hollow gold nanospheres (HGNs) are one of the few materials that are capable of converting light to heat and have been previously used for photothermal ablation studies. Selective(More)
