Project description:In the normal mouse the pituitary gonadotrophins determine development, maturation and physiological regulation of the testis with follicle-stimulating hormone (FSH) activating the Sertoli cell and luteinising hormone (LH) the Leydig cell. To look at the potential interaction of cell types within the testis following hormone stimulation we have investigated the effect of rFSH on testicular gene expression in the hypogonadal (hpg) male mouse. Due to a deletion in the gene encoding gonadotrophin-releasing hormone (GnRH), FSH and LH levels are at the lower limit of detection in the circulation and mice remain in a pre-pubertal state throughout life unless given exogenous hormone. Here we have addressed important question of changes in the global gene expression profile of testicular tissue following hormone stimulation (rFSH) for 12, 24 and 72h following injections compared to control untreated hpg males of the same age. Experiment Overall Design: Adult 10 week old hpg males were injected sc with 8 I.U. of rFSH (Gonal F, Serono Pharmaceuticals) in 0.2ml of PBS (Sigma,UK) every 12 h for 12, 24 and 72 h. Mice were killed one hour after the last injection by cervical dislocation, testes dissected out, weighed and snap frozen in liquid nitrogen. Tissue was stored at -70oC until use. RNA was extracted using Qiagen RNeasy Lipid Tissue Mini kit (Qiagen, Valencia, CA) according to the manufacturerâs instructions and quantified on a NanoDrop ND-1000 (NanoDrop Wilmington, DE). RNA quality was checked using the Agilent bioanalyzer 2100 (Agilent, Santa Clara, CA). Testicular gene expression was examined in four individual mice at 12 and 72 h and 3 mice at 24h using high-density oligonucleotide mouse MOE430A arrays (Affymetrix, Santa Clara, CA), comparison was made with a group of 7 untreated hpg males of the same age.

Project description:Inter-organ communication is a major hallmark of health and is often orchestrated by hormones released by the anterior pituitary gland. Pituitary gonadotropes secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to regulate gonadal function and control fertility. Whether FSH and LH also act on organs other than the gonads is debated. Here, we found that gonadotrope depletion in adult female mice triggers profound hypogonadism, obesity, glucose intolerance, fatty liver, and bone loss. The absence of sex steroids precipitates these phenotypes, with the notable exception of fatty liver, which results from ovary-independent actions of FSH. We uncover paracrine FSH action on pituitary corticotropes as a novel mechanism to restrain the production of corticosterone and prevent hepatic steatosis. Our data demonstrate that functional communication of two distinct hormone-secreting cell populations in the pituitary regulates hepatic lipid metabolism.

Project description:Using recombinant DNA technologies, a new chimeric gene containing the coding sequences of the follicle stimulating hormone (FSH) β-subunit and the C-terminal peptide of the human chorionic gonadotrophin (hCG) β-subunit have been designed to generate a new gonadotrophin named corifollitrophin alfa. Corifollitrophin alfa has longer elimination half-life and a slower rate of absorption compared with FSH, which makes corifollitrophin alfa a long-acting hormone employed as a substitute of the recombinant FSH (recFSH) in the controlled ovarian stimulation (COS). The purpose of this study is to compare the gene expression profiles elicited by bioequivalent doses of corifollitrophin alfa or recFSH in primary cultures of human granulosa cells (hGCs). Both gonadotrophins exert their functions by binding FSH receptors (FSHRs), activating signaling pathways that increase the cyclic adenosine monophosphate (cAMP) intracellular content. Bioequivalence has been defined as the dose/duration of gonadotrophin treatment able to promote the same amount of intracellular cAMP. Primary cultured hGCs were treated with different doses of either gonadotrophin and the cAMP was measured after different incubation times to establish the bioequivalence. Results obtained by comparing the bioequivalent treatments, showed that corifollitrophin alfa is more effective than recFSH in inducing aromatase gene expression after 6 and 24 hours from the initial stimulation in agreement with its long-acting characteristic’s.

Project description:Background: Melatonin (MLT) supplementation has been shown to improve the quality of oocytes and embryos in vitro through its antioxidant mechanism. However, it is unclear whether endogenous MLT plays a role in oocyte quality control, casting doubt on the rationality of oral MLT in improving oocyte quality or fecundity. Methods:we measured the effects of PMSG on MLT synthesis in follicles, evaluated the effects of MLT on oocyte growth and quality in mice and goat, used RNA-seq to explore the mechanism underlying MLT’s effects on oocyte growth and quality, and generated SNAT-knockout mice to assess the effects of endogenous MLT on oocyte growth and quality. Lastly, we investigated the feasibility of short-term MLT intake to improve the fertility of older mice. Result: we revealed that the follicle-stimulating hormone induces the expression of intra-ovarian SNAT, resulting in increased levels of intra-ovarian MLT in mice. Administering MLT during the gonadotropin-dependent phase improved the oocyte size and quality in both mice and goat by enhancing nutrient accumulation and mitochondrial function. Deficiency of MLT in mice reduced oocyte size and weakened mitochondrial function. Furthermore, our findings demonstrate that short-term MLT intake during the gonadotropin phase improves the litter size of older mice. Conclusion: This study reveals that endogenous MLT is involved in determining oocyte quality as a target molecule of follicle-stimulating hormone, shedding light on its potential utilization in improving oocyte quality or rejuvenating aged mammalian oocytes.

Project description:Loss of ovarian function imparts increased susceptibility to obesity and metabolic disease. These effects are largely attributed to decreased estradiol (E2), but the role of increased follicle stimulating hormone (FSH) in modulating energy balance has not been fully investigated. Previous work that inhibited FSH activity in mice suggested this hormone may play a part in modulating body weight and energy expenditure after ovariectomy. We used an alternate approach to experimentally isolate the individual and combined contributions of FSH and E2 in mediating energy imbalance and changes in tissue-level metabolic health. Female Wistar rats were ovariectomized and given the GnRH antagonist degarelix to suppress FSH production. E2 and FSH were then added back individually and in combination for a period of 3 weeks. Energy balance, body mass composition, and transcriptomic profiles of individual tissues were obtained. In contrast to previous studies, ablation and replacement of FSH in our paradigm had no effect on body weight, body composition, food intake, or energy expenditure. We did, however, observe organ-specific effects of FSH that produced unique transcriptomic signatures of FSH in retroperitoneal white adipose tissue. These included reductions in biological processes related to lipogenesis and carbohydrate transport. Additionally, rats administered FSH had reduced liver triglyceride concentration (p<0.001), which correlated with FSH-induced changes at the transcriptomic level. While not appearing to modulate energy balance after loss of ovarian function in rats, FSH may still impart tissue-specific effects in the liver and white adipose tissue that might affect the metabolic health of those organs.
