Epithelial ovarian cancer remains the most common type of malignant tumor of the female reproductive system worldwide. Routine surgery and chemotherapy are the best treatments available for patients with ovarian cancer; however, almost 40% of ovarian cancer cases are intractable, with poor 5-year survival rates. MicroRNAs (miRNA) are endogenous small non-coding RNA molecules that function in transcriptional and post-transcriptional regulation of gene expression in various cellular processes. Recent studies demonstrated that microRNA (miR)-124 was downregulated in numerous types of tumors; however, the function and mechanism underlying miR-124 in epithelial ovarian cancer remain unclear...

(1) Background: Epithelial ovarian cancer (EOC) is the most lethal cancer of the female reproductive system. In an earlier study, we identified multiple genes as hypermethylated in tumors of patients with poor prognosis. The most promising combination of markers to predict a patient's outcome was CaMKIINα and RUNX3. Aim of this study was to functionally validate the importance of both genes. (2) Methods: IC50 measurements, cell cycle distribution-, proliferation, and migration experiments were conducted after transgene overexpression in two EOC cell lines...

The mucosal tissues of the gut and female reproductive tract (FRT) are susceptible to pathogen infections including bacteria, viruses, and parasites, and are also the targets for immune disorders such as Crohn's disease, inflammatory bowel disease (IBD), and many types of cancers. However, the role of the mucosal immune cells to control these diseases is largely unknown. The limited availability of human mucosal biopsy tissue and the low number of cells that can be isolated from these tissues hampers the characterization of the phenotype and function of human mucosal immune cell subsets...

Cervical cancer is one of the most common malignant carcinomas in the female reproductive system. Long non-coding RNAs (lncRNAs) have been verified to participate in the tumorigenesis of cervical cancer. In present study, we investigate the role of lncRNA XLOC_008466 in the occurrence and progression of cervical cancer. Results showed that XLOC_008466 expression was up-regulated in cervical cancer tissue and cells compared to normal controls. In vitro functional experiments, CCK-8 assay and colony formation assay showed that XLOC_008466 knockdown suppressed the proliferation of cervical cancer cells...

Endometrial cancer (EC) is the most common cancer of the female reproductive tract in developed Countries. At the moment, no effective screening system is available. Here, we evaluate the diagnostic performance of a serum metabolomic signature. Two enrollments were carried out: one constituted of 168 subjects: 88 with EC and 80 healthy women, was used for building the classification models. The second (used to establish the performance of the classification algorithm) was constituted of 120 subjects: 30 with EC, 30 with ovarian cancer, 10 with benign endometrial disease and 50 healthy controls...

Breast cancer is the most commonly diagnosed malignancy in women around the globe. It is also the world's first cause of female deaths from cancer. With the introduction of screening programs in most developed countries, more and more cases of this cancer are diagnosed at local or localized stages, enabling radical treatment to be successful. At the same time, systemic treatment of early breast cancer is one of the most complex issues in clinical oncology. Because of the many prognostic factors that need to be taken into account when considering eligibility for treatment such as age, reproductive status (before or after menopause), type of cancer and severity of the disease, it is impossible to establish clear standards of conduct for many clinical situations...

Ensuring quality of life for increasing numbers of women surviving cancer has become a key challenge. Patients need to be counseled on potential fertility loss resulting from gonadotoxic treatments, and referred to fertility specialists to discuss existing options and available results. Areas covered: Fertility preservation options have existed for over twenty years. The proposed fertility preservation approach depends on patient age, the urgency of required chemotherapy, and psychosocial factors such as financial concerns, especially in countries where techniques are not covered by social security...

BACKGROUND: Estrogens, as the main female steroid hormones have multiple proven effects on reproductive and non- reproductive systems. Expression of ERα and ERβ, two dominant estrogen receptors, in peripheral blood mononuclear cells in certain B-cell malignancies and the existence of estrogens receptors on mitochondria is open to question that estrogen likely has an impact on the cancerous lymphocytes life span. Acute lymphoblastic leukemia (ALL) is the frequent pediatric malignity which is recurrent and hardly curable in many cases...

A sperm-driven micromotor is presented as a targeted drug delivery system, which is appealing to potentially treat diseases in the female reproductive tract. This system is demonstrated to be an efficient drug delivery vehicle by first loading a motile sperm cell with doxorubicin hydrochloride (DOX-HCl, an anticancer drug), then guiding it, using a synthetic magnetic harness, to an in vitro cultured tumor spheroid, and finally delivering the drug locally once the sperm cell is free by an integrated mechanical release mechanism...

Adult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically...

Cervical cancer is one of the most common malignancies of the female reproductive system. Therefore, it is critical to investigate the molecular mechanisms involved in the development and progression of cervical cancer. In this study, we stimulated cervical cancer cells with 5-aza-2'-deoxycytidine (5-Aza-dC) and found that this treatment inhibited cell proliferation and induced apoptosis; additionally, methylation of p16 and O-6-methylguanine-DNA methyltransferase (MGMT) was reversed, although their expression was suppressed...

BACKGROUND: Cervical cancer is one of the most common malignant tumours of the female reproductive system, ranking second only to breast cancer in morbidity worldwide. Essential features of the progression of cervical cancer are invasion and metastasis, which are closely related to disease prognosis and mortality rate. At the present time there is no effective method to evaluate cancer invasion and metastasis before surgery. Here we report our study on molecular changes in biopsy tissue for the prognostic evaluation of cancer invasion and metastasis...

Endometrial cancer (EC) is the most common familiar gynecologic malignant tumor identified in the female reproductive system and has been increasing yearly. In this study, we will identify the surface markers and stem cell markers related with cancer stem cells (CSCs) of EC. Tissue samples were obtained from endometrial cancer patients during surgical procedures. Single cells were isolated from the tissues for culturing, transfection into nude mice, and histopathology analysis. RT-PCR demonstrated that the cultured cells strongly expressed stemness-related genes, such as c-Myc, Sox-2, Nanog, Oct 4A, ABCG2, BMI-1, CK-18, Nestin and β-actin...

Epidemiologic studies have previously suggested that premenopausal females have reduced incidence of cardiovascular disease (CVD) when compared to age-matched males, and the incidence and severity of CVD increases postmenopause. The lower incidence of cardiovascular disease in women during reproductive age is attributed at least in part to estrogen (E2). E2 binds to the traditional E2 receptors (ERs), estrogen receptor alpha (ERα), and estrogen receptor beta (ERβ), as well as the more recently identified G-protein-coupled ER (GPR30), and can exert both genomic and non-genomic actions...

Health of the reproductive organs is essential for formation and production of high quality and hygienic eggs. It is of importance to review the structures and functions of female reproductive system for better understanding of the mechanism by which the eggs are formed. The unique functions of ovarian cells for follicular growth and differentiation as well as steroidogenesis and oocyte maturation are regulated by gonadotropins and gonadal steroids. The oviduct is responsible for egg formation, while the unique function to store sperms for a prolonged period takes place in the specific tissue of this organ...

Aging intersects with reproductive senescence in women by promoting a systemic low-grade chronic inflammation that predisposes women to several diseases including ovarian cancer (OC). OC risk at menopause is significantly modified by parity records during prior fertile life. To date, the combined effects of age and parity on the systemic inflammation markers that are particularly relevant to OC initiation and progression at menopause remain largely unknown. Herein, we profiled a panel of circulating cytokines in multiparous versus virgin C57BL/6 female mice at peri-estropausal age and investigated how cytokine levels were modulated by intraperitoneal tumor induction in a syngeneic immunocompetent OC mouse model...
