Human microRNA-125a-5p (miR-125a) is expressed in most tissues where it downregulates the expression of membrane receptors or intracellular transductors of mitogenic signals, thus limiting cell proliferation. Expression of this miRNA generally increases with cell differentiation whereas it is downregulated in several types of tumors, such as breast, lung, ovarian, gastric, colon, and cervical cancers, neuroblastoma, medulloblastoma, glioblastoma, and retinoblastoma. In this study, we focused on hepatocellular carcinoma and used real-time quantitative PCR to measure miR-125a expression in 55 tumor biopsies and in matched adjacent non-tumor liver tissues...

The phosphoinositide 3-kinase/AKT signaling pathway negatively regulates follicle activation via the forkhead box O (FOXO) transcription factor in rodents. FOXO3 knockout mice exhibit global activation of primordial follicles leading to early depletion of ovarian follicles and subsequent infertility. Whether a similar mechanism for follicle activation exists in the primate ovary is unclear. In the current study, protein localization of FOXO1, 3 and 4 as well as their upstream regulator, AKT/p-AKT, were examined in rhesus macaque ovaries of 3 developmental stages: fetal, prepubertal and adult...

Post-menopause hyperandrogenism is a condition that needs careful evaluation. Aromatase inhibitors (AI), which are important in the management of positive estrogen breast cancer, and chronic kidney disease (CKD) can puzzle the evaluation of this condition. A postmenopause female with type-2 diabetes and advanced CKD was attended due to progressive virilization, which has started after the introduction of an AI for breast cancer 5 years earlier. Clinical and radiological investigation has confirmed a pure Leydig cell tumor as source of hyperandrogenism...

Ovarian cancer is most lethal among all gynecologic malignancies. Paclitaxel (PTX) is well used chemotherapeutic regimen for cancer control; however its undesired toxicity has been always a matter of concern for clinicians. Here we used the graphene oxide coated nanotised apigenin (GO-NA) as chemo sensitizing agent to enhance the efficacy of paclitaxel to overcome the limitations of chemotherapy. GO and GO-Apigenin was prepared by modified Hummers method and the nanoparticles were characterized by dynamic light scattering and transmission electron microscopy Human ovarian adenocarcinomas (SKOV-3) cells was treated by DMSO, Group I (Control)-McCoy's 5A Medium, Group II-Paclitaxel (5nM) alone, Group III- Nanotised Apigenin (GO-NA-10μM) Group IV- Paclitaxel (5nM) + GO-NA (10μM)...

Ovarian cancer (OC) is the seventh most commonly diagnosed cancer among women in the world and the tenth most common in China. Epithelial OC is the most predominant pathologic subtype, with five major histotypes that differ in origination, pathogenesis, molecular alterations, risk factors, and prognosis. Genetic susceptibility is manifested by rare inherited mutations with high to moderate penetrance. Genome-wide association studies have additionally identified 29 common susceptibility alleles for OC, including 14 subtype-specific alleles...

Ovarian cancer accounts for the major part of the mortality attributable to female reproductive system malignant tumors worldwide. Recently, the incidence of ovarian cancer has been increasing annually, and there remains a lack of suitable treatment methods that can significantly improve the 5-year survival rates of patients. Therefore, it is necessary to identify more effective treatments for ovarian cancer. It is established that microRNAs (miRNAs) have important roles in the diagnosis and treatment of ovarian cancer and a specific miRNA, miR-762, can promote the development of a variety of tumors...

Despite standard treatment, about 70% of ovarian cancer will recur. Cancer stem cells (CSCs) have been implicated in the drug-resistance mechanism. Several drug resistance mechanisms have been proposed, and among these, autophagy plays a crucial role for the maintenance and tumorigenicity of CSCs. Compared to their differentiated counterparts, CSCs have been demonstrated to display a significantly higher level of autophagy flux. Moreover, mitophagy, a specific type of autophagy that selectively degrades excessive or damaged mitochondria, is shown to contribute to cancer progression and recurrence in several types of tumors...

Background: Adjuvant chemotherapy is a required treatment for most patients with epithelial ovarian cancer (EOC) or peritoneal cancer. However, it has many adverse events which may affect oncologic outcomes. Active hexose correlated compound (AHCC) has been reported to be an immunoenhancer to decrease adverse events of chemotherapy. Materials and Methods: Patients were randomized and allocated to receive either AHCC three grams/day (500mg/ capsule) or placebo. These drugs were administrated as two capsules orally three times a day throughout six cycles of chemotherapy...

The degree of peritoneal dissemination and chemotherapy-resistant tumors is related to the prognosis in patients with advanced-stage ovarian cancer. The epithelial-mesenchymal-transition (EMT) is a multifaceted pathological program that endows cancer cells with the ability to invade and disseminate. CD24 is frequently overexpressed in various human cancers and is correlated with a poor prognosis. We herein examined the functions of CD24 in human ovarian cancer cell lines and evaluated how it contributes to the molecular mechanism underlying the regeneration of cancer stem-like cells (CSCs) through the EMT mechanism in ovarian carcinoma...

Hydrogen sulfide (H2S), the third gasotransmitter, plays important roles in cancer biological processes. As endogenous H2S exerts pro-cancer functions, inhibition of its production in cancer cells may provide a new cancer treatment strategy and be achieved via regulation of the function of cystathionine β-synthase (CBS), one of the main metabolic enzymes synthesizing H2S. This enzyme plays important roles in the development and progression of colon and ovarian cancer, primarily regulating mitochondrial bioenergetics and accelerating cell cycle progression...

Annexin A2 is a member of the Annexin family that acts as a Ca2+-dependent phospholipid and membrane binding protein, which is associated with the survival and spread of multiple neoplasms. However, the function of Annexin A2 in ovarian cancer progression remains unclear. In this study, we aimed to investigate the role and underlying molecular mechanism of Annexin A2 in cell proliferation and invasion in ovarian cancer. We found that the mRNA expression of Annexin A2 was upregulated in ovarian cancer tissues and cell lines...

Cell-free microRNAs (miRNAs) have become one of the novel promising diagnostic and prognostic biomarkers for various diseases recently. Blood serum and plasma along with urine are the most common sources of clinically well, almost noninvasively available samples containing various types of miRNAs. Here, we present a protocol for a small-scale study investigating expression of several candidate miRNAs. Small-scale experiments may be worth investigating in cases where no information is available on miRNAs expression in particular diseases, for validation of previously published miRNAs with promising diagnostic potential, particularly in situations where follow-up study is aimed at validating miRNAs coming from array or NGS experiments, or where funding for these large-scale experiments is not available...

Ovarian cancer is the seventh most common cancer in women and the most lethal gynecological cancer, causing over 151,000 deaths worldwide each year. Dysregulated production of endocrine hormones, known to have pluripotent effects on cell function through the activation of receptor signaling pathways, is believed to be a high-risk factor for ovarian cancer. An increasing body of evidence suggests that endocrine G protein-coupled receptors (GPCRs) are involved in the progression and metastasis of ovarian neoplasms...
