Project description:Reproductive efficiency is of significant importance in pork production for it has a great impact on economic success. Ovulation rate is an early component of reproduction efficiency of pigs, and it contributes to the upper limit of litter size. In this study, we used the newly developed recombinant pig follicle stimulating hormone (rpFSH) instead of traditional PMSG to increase ovulation rate of pigs in order to achieve higher litter size, for it was better at stimulating ovulation, and showed more cheaper and greener. However, relatively little is known about the underlying genetic bases and molecular mechanisms. Consequently, an experiment was carried out in ovaries of replacement gilts to screen the key genes and lncRNAs that affect the fecundity of pigs by RNA-seq technology. Twenty gilts were divided into two groups, including 10 rpFSH treatment pigs and 10 control animals. After slaughtering and collecting the phenotypic data, ovaries of five pigs in each group were selected for RNA-seq. Total RNA was extracted to construct the library and then sequence on an Illumina Hiseq 4000 system. A comprehensive analysis of mRNAs and long non-coding RNAs (lncRNAs) from 10 samples was performed with bioinformatics. The phenotypic data showed that rpFSH treatment groups had the higher (P < 0.01) ovarian weight and more mature follicles. The RNA-seq results showed that a total of 43,499 mRNAs and 21,703 lncRNAs were identified, including 21,300 novel lncRNAs and 403 known lncRNAs, of which 585 mRNAs and 398 lncRNAs (P < 0.05) were significantly differentially expressed (DE) between the two groups of rpFSH treatment group and controlled group. GO and KEGG annotation analysis indicated that the target genes of DE lncRNAs and DE mRNAs were related to prolactin receptor activity, mitophagy by induced vacuole formation, and meiotic spindle. Moreover, we found that NR5A2 (nuclear receptor subfamily 5, group A, member 2), a target gene of lncRNA MSTRG.3902.1, was involved in regulating follicular development, ovulation, and estrogen production. Our study provided a catalog of lncRNAs and mRNAs associated with ovulation of rpFSH treatment, and they deserve further study to deepen the understanding of biological processes in the regulation of ovaries of rpFSH treatment pigs.

Project description:FSH is considered as the most critical regulatory factor for follicle growth and development. It is widely acknowledged that exogenous administration of FSH can effectively stimulate ovulation.However, these techniques have several drawbacks such as high cost and detrimental effects on hormone balance and embryo implantation.Sulforaphane (SFN) is a naturally occurring compound that belongs to the isothiocyanate group, which is predominant in cruciferous vegetables.Our previous research demonstrated SFN could inhibit hypoxia-evoked apoptosis in porcine GCs. Intriguingly, SFN exhibits a biphasic dose-response, stimulating cell growth at low doses in various mammalian cells. Therefore,to investigate the functional implications of sulforaphane in the regulation of granulosa cell proliferation, we conducted a gene expression profiling analysis using RNA-seq data, comparing SFN to follicle stimulating hormone (FSH).

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:Gene expression analysis of porcine granulosa cells treated in virtro with sulforaphane or follicle stimulating hormone

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:Successful production of offspring in mammals is determined by the growth and apoptosis pathway, which is responsible for maintaining the balance between the estrous cycle. It is also believed that the development of the porcine ovary is regulated similarly; however, the molecular mechanism underlying differences in follicle development in the minipig and pig has yet to be elucidated. The present study aimed to identify developmental-associated genes differentially expressed in the minipig vs. pig.
