Current status of treatment for malignant ovarian sex cord-stromal tumors.

Malignant ovarian sex cord-stromal tumors belong to a specific type of ovarian epithelial carcinoma, and their prognosis is related to the kind of pathology. Unlike epithelial ovarian cancer, most malignant ovarian sex cord-stromal tumors are low-grade malignant and have a good prognosis. Still, they have a tendency to recur in the long term, and the mortality rate of patients after recurrence is high.

GC-MS-based untargeted plasma metabolomics identifies a 2-biomarker panel for possible diagnosis of precancerous cervical intraepithelial neoplasia stages from cervical cancer.

Cervical cancer (CC) remains a major health concern globally, much of the brunt of which is experienced by the low- and middle-income countries where screening in terms of cytology and DNA genotyping for the high-risk oncogenic subtypes of the human papilloma virus (hr-HPV) is either inadequate or performed rather late. In this study, we aimed to determine biomarkers or panels of biomarkers that are capable of diagnosing the precancerous cervical intraepithelial neoplasia (CIN) stages from healthy and CC patients via untargeted gas chromatography-mass spectrometry-based metabolomics. Various cross-comparisons were conducted from which differential metabolites were identified.

Label-free single-particle imaging approach for ultra-rapid detection of pathogenic bacteria in clinical samples.

Rapid detection of pathogenic bacteria within a few minutes is the key to control infectious disease. However, rapid detection of pathogenic bacteria in clinical samples is quite a challenging task due to the complex matrix, as well as the low abundance of bacteria in real samples. Herein, we employ a label-free single-particle imaging approach to address this challenge.

Autotransplantation of the ovarian cortex after in-vitro activation for infertility treatment: a shortened procedure.

Study Question: Is it possible to establish a new in-vitro activation (IVA) protocol for infertility treatment?

Summary Answer: A new IVA procedure is an efficient and easily performed approach for infertility treatment of patients with diminished ovarian reserve (DOR).

What Is Known Already: IVA of primordial follicles with or without stimulators has been developed to treat patients with primary ovarian insufficiency (POI) successfully. However, the efficiency of the procedure is still very low.

Long non-coding RNA SNHG25 promotes epithelial ovarian cancer progression by up-regulating COMP.

Long non-coding RNAs (lncRNAs) play a pivotal role in the genesis and development of cancer. The role and molecular mechanisms of SNHG25 in epithelial ovarian cancer (EOC) have not been investigated. In the present study, we showed that SNHG25 expression was up-regulated in EOC tissues relative to normal ovarian tissues.

The protective effects of rapamycin pretreatment on ovarian damage during ovarian tissue cryopreservation and transplantation.

Ovarian tissue cryopreservation and transplantation (OCT) has been sufficiently proven effective and feasible to preserve fertility for women especially for prepubertal girls suffering from cancer with radiotherapy and chemotherapy. However, grafts' survival, significant follicle loss and a delay of revascularization during OCT still need to be resolved no matter what kind of cryopreserved method being used. Different from previous reports about additives treatment on recipient after ovarian transplantation, we here report a new vitrification protocol with pretreatment of rapamycin, an inhibitor of the mTOR signaling pathway.

Wilms' tumor 1 () promotes ovarian cancer progression by regulating E-cadherin and ERK1/2 signaling.

Wilms' tumor 1 () is reported to play an important role in tumor invasion and metastasis, two hallmarks of ovarian cancer (OC) that influence treatment efficacy and prognosis. However, the specific roles and underlying mechanisms of in OC have not been fully understood. Here, we investigated the potential function and signaling pathways of in OC cells.

Role of potassium channels in female reproductive system.

Potassium channels are widely expressed in most types of cells in living organisms and regulate the functions of a variety of organs, including kidneys, neurons, cardiovascular organs, and pancreas among others. However, the functional roles of potassium channels in the reproductive system is less understood. This mini-review provides information about the localization and functions of potassium channels in the female reproductive system.

Decreased microRNA-125b-5p disrupts follicle steroidogenesis through targeting PAK3/ERK1/2 signalling in mouse preantral follicles.

Background: Hyperandrogenism is one of the major characteristics of polycystic ovary syndrome (PCOS). Abnormal miR-125b-5p expression has been documented in multiple diseases, but whether miR-125b-5p is associated with aberrant steroidogenesis in preantral follicles remains unknown.

Methods: Steriod hormone concentrations and miR-125b-5p expression were measured in clinical serum samples from PCOS patients.

HucMSC-Derived Exosomes Mitigate the Age-Related Retardation of Fertility in Female Mice.

In mammals, resting primordial follicles serve as the ovarian reserve. The decline in ovarian function with aging is characterized by a gradual decrease in both the quantity and quality of the oocytes residing within the primordial follicles. Many reports show that mesenchymal stem cells have the ability to recover ovarian function in premature ovarian insufficiency (POI) or natural aging animal models; however, the underlying mechanism remains unclear.

Knocking down of LINC01220 inhibits proliferation and induces apoptosis of endometrial carcinoma through silencing MAPK11.

Endometrial carcinoma (EC) still threatens the health of women. Thus, to explore how long intergenic non-protein coding RNA 01220 regulates the development of EC. Whole genome expression profile data of EC and paracancerous tissues in TCGA database were downloaded.

Perfluorooctanoic acid stimulates ovarian cancer cell migration, invasion via ERK/NF-κB/MMP-2/-9 pathway.

As widely used in consumer products, perfluorooctanoic acid (PFOA) has become a common environmental pollutant, which has been detected in human serum and associated with cancers. Our previous study showed that PFOA is a carcinogen that promotes endometrial cancer cell migration and invasion through activation of ERK/mTOR signaling. Here, we showed that PFOA (≥100 nM) treatment also stimulated A2780 ovarian cancer cell invasion and migration, which correlated with increased matrix metalloproteinases MMP-2/-9 expression, important proteases associated with tumor invasion and migration.
