Premature ovarian failure (POF) is an ovarian defect characterized by the premature depletion of ovarian follicles in individuals <40 years old, and is a major cause of infertility in females. Genetic factors are considered to be responsible for the development of POF, however, the exact pathogenesis remains to be elucidated in the majority of cases. In the present study, the single nucleotide ...

Follicle-stimulating hormone receptor (FSHR) is a leucine-rich repeat containing class A G-protein coupled receptor belonging to the subfamily of glycoprotein hormone receptors (GPHRs), which includes luteinizing hormone/choriogonadotropin receptor (LH/CGR) and thyroid-stimulating hormone receptor. Its cognate ligand, follicle-stimulating hormone binds to, and activates FSHR expressed on the su...

Stem cell factor (SCF) is essential for the development of primordial follicles. By using cultured ovaries from neonatal rats, the effect of SCF on early follicular development was investigated. Steroidogenesis is a hallmark of follicular development. Expressions of three key protein factors in steroidogenesis, SF-1, StAR, and P450arom, were investigated using immunohistochemistry and in situ h...

Innate immunity is an ancient defense system used by both vertebrates and invertebrates. Previously characterized innate immune responses in plants and animals are triggered by detection of pathogens using specific receptors, which typically use a leucine-rich repeat (LRR) domain to bind molecular patterns associated with infection. The nematode Caenorhabditis elegans uses defense pathways cons...

The study aimed to investigate the effects of FSH and eCG on the ovarian and follicular development, expression levels of FSHR and caspase-9 of ovaries in vivo. One hundred and five prepuberty mice were allocated into FSH-1, FSH-2, FSH-3, eCG-1, eCG-2, eCG-3 groups and control group (CG). Mice in FSH-1, FSH-2 and FSH-3 were intramuscularly injected with 5, 10 and 20 IU FSH twice (on day 0 and 4...

Chemotherapy is an important treatment for ovarian cancer. However, conventional chemotherapy has inevitable drawbacks due to side effects from nonspecific biodistribution of the chemotherapeutic drugs. To solve such problem, targeted delivery approaches were developed. The targeted delivery approaches combine drug carriers with the targeting system and can preferentially bring drugs to the tar...

BACKGROUND Bisphenol-A (BPA) is one of the widespread industrial compounds, which has adverse effects on animal and human health. The study was aimed to explore the effects of Crassostrea gigas extracts (CGE) in alleviating ovarian functional disorders of female rats with exposure to BPA and the underlying possible mechanism. MATERIALS AND METHODS Eighteen four-week-old female Sprague-Dawley ...

BACKGROUND Clomiphene citrate (CC) response in anovulatory women is difficult to predict and patient-tailored treatment would benefit patient care and time-management. The objective of this study was to evaluate the role of the follicle-stimulating hormone receptor (FSHR) Ser680Ser-polymorphism as a predictor for CC response. METHODS In this retrospective study, 193 patients, diagnosed with p...

Nanovehicles are promising delivery systems for various vaccines. Nevertheless, different biophysicochemical properties of nanoparticles (NPs), dominating their in vitro and in vivo performances for vaccination, remain unclear. We attempted to elucidate the effects of NPs and their pH-sensitivity on in vitro and in vivo efficacy of resulting prophylactic nanovaccines containing a contraceptive ...
