Granulosa cell apoptosis in the ovarian follicle - a changing view [PDF]

, 2018
Recent studies challenge the previous view that apoptosis within the granulosa cells of the maturing ovarian follicle is a reflection of aging and consequently a marker for poor quality of the contained oocyte.

Small Molecule Follicle-Stimulating Hormone Receptor Agonists and Antagonists

Frontiers in Endocrinology, 2019
The follicle-stimulating hormone receptor (FSHR) has been targeted therapeutically for decades, due to its pivotal role in reproduction. To date, only purified and recombinant/biosimilar FSH have been used to target FSHR in assisted reproduction, with ...

AreFSHRpolymorphisms risk factors to premature ovarian insufficiency?

Gynecological Endocrinology, 2015
Premature ovarian insufficiency (POI) is an ovarian dysfunction characterized by increased FSH levels and amenorrhea before 40 years old. In recent years, the search for genetic causes of POI intensified and studies have been published relating the presence of mutations and polymorphisms in genes associated with development, recruitment and oocyte ...

Spermatogenesis and sertoli cell activity in mice lacking Sertoli cell receptors for follicle stimulating hormone and androgen [PDF]

, 2008
Spermatogenesis in the adult male depends on the action of FSH and androgen. Ablation of either hormone has deleterious effects on Sertoli cell function and the progression of germ cells through spermatogenesis.

The preparation and application of N-terminal 57 amino acid protein of the follicle-stimulating hormone receptor as a candidate male contraceptive vaccine

Asian Journal of Andrology, 2014
Follicle-stimulating hormone receptor (FSHR), which is expressed only on Sertoli cells and plays a key role in spermatogenesis, has been paid attention for its potential in male contraception vaccine research and development.

Characterization of gonadotropin receptors Fshr and Lhr in Japanese medaka, Oryzias latipes

General and Comparative Endocrinology, 2020
Reproduction in vertebrates is controlled by the brain-pituitary-gonad axis, where the two gonadotropins follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh) play vital parts by activating their cognate receptors in the gonads. The main purpose of this work was to study intra- and interspecies ligand promiscuity of teleost gonadotropin ...

Assessment of FSHR, AMH, and AMHRII variants in women with polycystic ovary syndrome [PDF]

Endocrine, 2014
Polycystic ovary syndrome (PCOS) is the most frequentendocrinopathy present in 6–15 % of reproductive-agewomen [1]. It is a heterogenous syndrome [2, 3] andaccording to the Rotterdam Criteria [4], PCOS is recog-nized in women who have two of three symptoms: chronicamenorrhea, clinical or biochemical hyperandrogenism andthe ovarian morphology of PCO in ...

Pathogen Response Genes Mediate Caenorhabditis elegans Innate Immunity

, 2012
Innate immunity is crucial in the response and defense against pathogens for invertebrates and vertebrates alike. The soil nematode Caenorhabditis elegans is a useful model to study the eukaryotic innate immune response to microbial pathogenesis.
