Discovery & development of small molecule allosteric modulators of glycoprotein hormone receptors

open access: yesFrontiers in Endocrinology, 2015
Glycoprotein hormones, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and thyroid stimulating hormone (TSH) are heterodimeric proteins with a common subunit and hormone-specific subunit.

Luteinizing hormone concentrations in healthy horses and horses with trigeminal-mediated headshaking over an 8-hour period. [PDF]

open access: yes, 2019
BackgroundTrigeminal-mediated headshaking results from a low threshold for firing of the trigeminal nerve. A seasonal component has been implicated in onset of clinical signs, which occur during the spring and summer months.

Further characterization of adult sheep ovarian stem cells and their involvement in neo-oogenesis and follicle assembly

open access: yesJournal of Ovarian Research, 2018
Background Stem cells in the ovary comprise of two distinct populations including very small embryonic-like stem cells (VSELs) and slightly bigger progenitors termed ovarian stem cells (OSCs).

The spatiotemporal expression pattern of the bone morphogenetic protein family in rat ovary cell types during the estrous cycle. [PDF]

open access: yes, 2003
In the mammalian ovary, great interest in the expression and function of the bone morphogenetic protein (BMP) family has been recently generated from evidence of their critical role in determining folliculogenesis and female fertility.

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]

open access: yes, 2015
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Ontogeny of the specificity of gonadotropin receptors and gene expression in carp

open access: yesEndocrine Connections, 2019
The pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are the principle endocrine drivers of reproductive processes in the gonads of jawed vertebrates.

Novas perspectivas no diagnóstico do hipogonadismo pediátrico masculino: a importância do AMH como marcador de células de Sertoli [PDF]

open access: yes, 2011
Sertoli cells are the most active cell population in the testis during infancy and childhood. In these periods of life, hypogonadism can only be evidenced without stimulation tests, if Sertoli cell function is assessed.

Thyroxine-binding globulin: investigation of microheterogeneity [PDF]

open access: yes, 1981
Preparations of T4-binding globulin (TBG) from human serum was performed using only two affinity chromatography steps. Purity of the protein was demonstrated by a single band in overloaded disc and sodium dodecyl sulfate electrophoresis, equimolar ...

Mapping the follicle-stimulating hormone-induced signalling networks

open access: yesFrontiers in Endocrinology, 2011
Follicle-stimulating hormone (FSH) is a central regulator of male and female reproductive function. Over the last decade, there has been a growing perception of the complexity associated with FSH-induced cellular signalling.

A Novel Hypothesis: A Role for Follicle Stimulating Hormone in Abdominal Aortic Aneurysm Development in Postmenopausal Women

open access: yesFrontiers in Endocrinology, 2021
An abdominal aortic aneurysm (AAA) is a dilatation of the abdominal aorta, which can potentially be fatal due to exsanguination following rupture. Although AAA is less prevalent in women, women with AAA have a more severe AAA progression compared to men ...
