Objective To investigate the association between two polymorphisms of follicle stimulating hormone receptor （FSHR） gene and polycystic ovary syndrome （PCOS） susceptibility. Methods Case-control studies on relationship of Thr307Ala and Asn680Ser polymorphisms in FSHR gene and PCOS susceptibility were searched from PubMed, ISI web of knowledge, EBSCO, and China National Knowledge Infrastructure （CNKI） databases up to March 21, 2013. The pooled odds ratio （OR） and 95% confidence interval （CO were calculated using fixed- or random-effect model based on heterogeneity test in 5 genotype models analyses. Results A total of 11 studies were included in the Meta-analysis. The random-effect analysis showed Asn680Ser was significantly associated with the reduced susceptibility to PCOS with dominant model （Asn/Asn＋Asn/Ser vs. Ser/Ser, OR=0.83, 95% CI： 0.69-1.00）, recessive model （Asn/Asn vs. Asn/Ser＋ Ser/Ser, OR=0.84, 95% CI： 0.72-0.98）, homozygote comparison （Ash/Ash vs. Ser/Ser, 0R=0.79, 95% CI： 0.63-0.98）, and the allele contrast （Asn vs. Ser, OR=0.87, 95% CI： 0.79-0.97） respectively（P=0.02, I2=56.0%）, being protective factors for PCOS. However, no significant associations were found between Thr307Ala and PCOS. Conclusion There might be a significant association between Asn680Ser polymorphism and PCOS.

Fluoride Exposure,Follicle Stimulating Hormone Receptor Gene Polymorphism and Hypothalamus-pituitary-ovarian Axis Hormones in Chinese Women

The effects of fluoride exposure on thefunctions of reproductive and endocrine systemshave attracted widespread attention in academiccircle nowadays. However, it is unclear whether thegene-environment interaction may modify thesecretion and activity of hypothalamus-pituitary-ovarian （HPO） axis hormones. Thus, the aim of thisstudy was to explore the influence of fluorideexposure and follicle stimulating hormone receptor（FSHR） gene polymorphism on reproductivehormones in Chinese women. A cross sectionalstudy was conducted in seven villages of HenanProvince, China during 2010-2011. A total of 679women aged 18-48 years were recruited throughcluster sampling and divided into three groups, i.e.endemic fluorosis group （EFG）, defluoridationproject group （DFPG）, and control group （CG） basedon the local fluoride concentration in drinkingwater. The serum levels of gonadotropin releasinghormone （GnRH）, follicle stimulating hormone（FSH）, luteinizing hormone （LH）, and estradiol （E2）were determined respectively and the FSHRpolymorphism was detected by real time PCR assay.The results provided the preliminary evidenceindicating the gene-environment interaction onHPO axishormones in women.

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

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. This study introduces a method for the preparation and purification of human FSHR 57-amino acid protein （FSHR-57aa） as well as determination of its immunogenicity and antifertility effect. A recombinant pET-28a（＋）-FSHR-57aa plasmid was constructed and expressed in Escherichia coil strain BL21 StarTM （DE3） and the FSHR-57aa protein was separated and collected by cutting the gel and recovering activity by efficient refolding dialysis. The protein was identified by Western blot and high-performance liquid chromatography analysis with a band of nearly 7 kDa and a purity of 97.4%. Male monkeys were immunized with rhFSHR-57aa protein and a gradual rising of specific serum IgG antibody was found which reached a plateau on day 112 （16 weeks） after the first immunization. After mating of one male with three female monkeys, the pregnancy rate of those mated with males immunized against FSHR-57aa was significantly decreased while the serum hormone levels of testosterone and estradiol were not disturbed in the control or the FSHR-57aa groups. By evaluating pathological changes in testicular histology, we found that the blood-testis barrier remained intact, in spite of some small damage to Sertoli cells. In conclusion, our study demonstrates that the rhFSHR-57aa protein might be a feasible male contraceptive which could affect sperm production without disturbing hormone levels.

Cloning and Transcriptional Activity of Follicle-Stimulating Hormone Receptor Promoter in the Jintang Black Goat

[ Objective] To clone follicle-stimulating hormone receptor （FSHR） promoter in the Jintang black goat, study its transcriptional activity, and provide a basis for alternative splicing of FSHR gene. [Method] The total DNA were extracted from the womb of Jintang black goat, and one pair of primers were designed for amplification of FSHR promoter fragments, then the sequences and homology were analyzed. The FSHR promoter fragment was inserted into the pcFSHRB1 expression vector to substitute the CMV promoter and construct the pcFSHRB2 expression vector. The pcFSHRB1 and pcFSHRB2 expression vectors were transformed into HEK293 cells, respectively. Then these cells were collected after 24 and 48 h treatment with 2 mlU/ml follicle-stimulating hormone （FSH）, and the cAMP levels were detected. [Result] The FSHR promoter sequence of Jin- tang black goat had 34.2% homology to that of chicken and 41.6% to that of rat, respectively. The transcription initial site of FSHR was at -576 bp and its upstream sequences contained two TATA-boxes, four CAAT-boxes, one E-box and one Wl-box. After treating for 24 and 48 h, the cAMP levels of pcFSHRB2 were respectively 299.581 3 and 125.528 1 pmol/L; and that of pcFSHRB1 were respectively 120.057 1 and 109.940 7 pmoVL. [Conclusion] The FSHR promoter of Jintang black goat is a typical type 2 eukaryotic promoter, and it is also a strong promoter.

Quantification of Porcine Follicle-stimulating Hormone Receptor Messenger Ribonucleic Acid by Reverse Transcription competitive Polymerase Chain Reaction

An easy and reliable method was developed for construction and quantification of competitive templates, which shared the same sequence as the amplified target DNA except for a 20 bp insertion in the middle by recombinant polymerase chain reaction (PCR). Among the advantages of competitive PCR is that any predictable or unpredictable variable that affects amplification has the same effect on both target and competitor species and that the final ratio of amplified products reflects exactly the initial targets. The utilization of a thermostable reverse transcriptase in the RT step was proposed to overcome the problem of the efficiency of target cDNA synthesis. In addition, to obtain reliable measurements, it was recommended to perform four PCR with amounts of competitive template flanking the concentration of the target mRNA.

Effects of Antisense Oligodeoxynucleotide to Follicle-stimulating Hormone Receptor on the Cell Proliferation and Apoptosis in Cells Derived from Human Ovarian Mucinous Cystadenocarcinoma in Vitro

The human ovarian mucinous cystadenocarcinoma （hOMC） cells were co-cultured with antisense oligodeoxynucleotide （antisense ODN）, nonsense ODN, and follicle-stimulating hormone （FSH） at different concentrations for the purpose of observing the effects of antisense ODN to FSH receptor （FSHR） on the proliferation and apoptosis of cultured hOMC cells in vitro. The inhibitory rates of growth were measured by using MTT method on the 2nd, 4th, 6th, 8th and 10th days after the interference of antisense ODN, nonsense ODN, and FSH, respectively. The apoptotic rates and the cell cycles were determined by means of flow cytometry, the apoptosis indexes were detected by using TUNEL, and the expression of caspase-3 was measured by using SP immunohistochemistry. Compared with that in the control group, the proliferative activity of hOMC cells was increased obviously in FSH groups （P〈0.05 or P〈0.01）, decreased distinctly in antisense ODN groups （P〈0.05 or P〈0.01）, and unchanged in nonsense ODN groups, respectively. Meanwhile, antisense ODN could significantly antagonize the FSH-promoted cell proliferative activity （P〈0.01）. Compared with those in the control group, the apoptotic rates and the expression of caspase-3 were dramatically increased in the mid- and high-dose antisense ODN groups （P〈0.05 or P〈0.01）, while the number of cells in G1/G0 phase was significantly decreased and that in S phase distinctly increased （P〈0.01）, There was no change in nonsense ODN groups （P〉0.05）, It was suggested that FSH may improve the development of hOMC cells, However, antisense ODN could inhibit proliferative activity and the FSH-promoted proliferative activity in hOMC cells, at the same time, antisense ODN could inhibit hOMC cell growth by inducing apoptosis.

Cloning and Expression Level Analysis of Melanocyte-stimulating Hormone Receptor 1 Gene(MC1R) in Alpacas with Different Coat Color

Specific primers for the MC1R gene of alpacas(GenBank EU1358800) were designed to amplify the cDNA sequence using RT-PCR to seek variation in the sequence and explore the relationship between the expression level of MC1R gene and alpaca coat color.The MC1R gene from white alpaca was cloned successfully and sequence analysis verified that the MC1R gene,encoding 317 amino acids,was 1081 bp in length.Compared with the existing sequence in GenBank,sequence identity was 99.9%and 7 mutations were found.Primers,designed from the sequence obtained,were used to assess the relative expression of MC1R in alpacas of different coat color using QRT-PCR and SPSS 13.0 software.Relative expression of MC1R in the skin of brown alpacas was 4.32 times higher than that in white alpacas after normalization with GAPDH(P【0.01),indicating that MC1R expression may be related to coat color of alpacas.

The Determination and Evaluation of the Biological Activities for the Commercialization of Recombinant Follicle-Stimulating Hormone in Vitro

Follicle-stimulating hormone (FSH) plays a central role in mammals reproduction, with the actions of FSH mediated by follicle-stimulating hormone receptors (FSHRs) on the surface of target cells. The purposes of this study were to determine and evaluate the biological activities for the commercialization of recombinant follicle-stimulating hormone (rFSH) in vitro through the cellular internalization using cloned 293T-FSHR cell lines as target. Using imaging approaches we have found here that a little fluorescent signal from the surface of the cell transferred to the cytoplasm and accumulated around the nucleus by endocytosis. Compared with the control groups, the commercialization of rFSH have not the significant differences of internalization, but the rFSH have promoted the internalization of the fluorescent, suggested that this detection system might as a protocol for the bioactivity of recombinant therapeutic proteins in vitro.

Association of Thr307Ala and Asn680Ser of Follicle-Stimulating Hormone Receptor Gene Polymorphisms with Gonadotropin Administration during Controlled Ovarian Hyperstimulation

Objective:This study is to investigate the effect of different single-nucleotide polymorphisms of follicle-stimulating hormone receptor(FSHR)gene on gonadotropin(Gn)administration dosage during controlled ovarian hyperstimulation(COH)protocol of in vitro fertilization and embryo transfer.Methods:This retrospective study included 184 Chinese infertile women in Center for Reproduction and Genetics of Suzhou Municipal Hospital from June 2012 to 2014.All of the enrolled patients were homogeneous in some basal characteristics,and they all met the eligibility criteria.Blood tests were conducted on day 3 of menstrual cycle or the day of human chorionic gonadotropin administration for hormonal profile analysis and DNA extraction.DNA sequencing was performed for polymorphism analysis.The participants were classified into threonine(Thr)/Thr,Thr/alanine(Ala),and Ala/Ala groups according to genotype at position 307,and asparagine/asparagine(Asn/Asn),Asn/serine(Ser),and Ser/Ser groups according to genotype at position 680.Logistic regression and correlation analyses were performed to identify the effect of these two polymorphisms on Gn consumption.Results:The frequency of Thr307Ala and Asn680Ser distribution was consistent with Hardy-Weinberg equilibrium(P>0.05).No significant difference was found in age,basal hormone levels for different genotype groups.Logistic regression analysis results revealed that patients with Ser680Ser genotype have a higher risk of requiring a high dose of Gn compared with patients with Asn680Asn genotype,while polymorphism of Thr307 Ala has no such effect.Conclusion:This study suggested that FSHR genotype Asn680Ser would be helpful in determining the dosage of Gn in COH;patients with Ser680Ser genotype may require higher dose of Gn.

High expression of follicle stimulating hormone receptor in testicular tissue of idiopathic azoospermic patients with severe spermatogenic defects

Background Follicle stimulating hormone is necessary for normal reproduction in men.The biochemical actions of follicle stimulating hormone result from binding to the follicle stimulating hormone receptor in the plasma membrane of Sertoli cells.Here,we investigated the expression of the follicle stimulating hormone receptor in different testicular histological phenotypes of patients with idiopathic azoospermia.Methods Fifty-seven cases of idiopathic azoospermia were classified into three groups according to the results of testicular biopsy：patients with hypospermatogenesis,patients with maturation arrest,and patients with Sertoli cell-only syndrome.Thirteen azoospermic patients identified by testicular biopsy as being capable of completing spermatogenesis acted as the control group.Immunohistochemistry and real-time quantitative reverse-transcriptase polymerase chain reaction were performed in each case,and the serum hormone level was also measured in all patients.Results The serum follicle stimulating hormone level in patients with Sertoli cell-only syndrome was significantly higher than in patients with hypospermatogenesis,maturation arrest,and complete spermatogenesis （P＜0.01）.The serum follicle stimulating hormone level in patients with maturation arrest was significantly higher than in patients with hypospermatogenesis and complete spermatogenesis （P＜0.05）.There was no difference in serum follicle stimulating hormone levels in patients with hypospermatogenesis and complete spermatogenesis.The follicle stimulating hormone receptor expression level of testicular samples with Sertoli cell-only syndrome was significantly higher than in those with hypospermatogenesis,maturation arrest,and complete spermatogenesis （P＜0.05）,but no significant difference was observed among hypospermatogenesis,maturation arrest,and complete spermatogenesis testicular samples.Conclusions Different serum follicle stimulating hormone levels and follicle stimulating hormone receptor expression were found in the different testicular histology phenotypes in azoospermic patients.Differential follicle stimulating hormone receptor expression in testicular tissue of patients with idiopathic azoospermia may be associated with the degree of spermatogenesis.

Predictors for partial suppression of spermatogenesis of hormonal male contraception

Aim： To analyze factors influencing the efficacy of hormonal suppression of spermatogenesis for male contraception. Methods： A nested case-control study was conducted, involving 43 subjects, who did not achieve azoospermia or severe oligozoospermia when given monthly injections of 500 mg testosterone undecanoate （TU）, defined as partial suppressors compared with 855 subjects who had suppressed spermatogenesis （complete suppressors）. Sperm density, serum testosterone, luteinizing hormone （LH） and follicle stimulating hormone （FSH） concentrations at the baseline and the suppression phase were compared between partial and complete suppressors. Polymorphisms of androgen receptor （AR） and three single nucleotide variants and their haplotypes of FSH receptor （FSHR） genes determined by polymerase chain reaction （PCR） and DNA sequencing technique were compared between 29 partial and 34 complete suppressors. Results： Baseline serum LH level was higher and serum LH as well as FSH level during the suppression phase was less suppressed in partial suppressors. Additionally, in a logistic regression analysis larger testis volume, higher serum FSH concentrations alone, or interaction of serum LH, FSH, testosterone and sperm concentrations were associated with degree of suppression. The distribution of polymorphisms of AR or FSH receptor genes did not differ between partial and complete suppressors. In cases with incomplete FSH suppression （FSH 〉 0.2 IU/L）, the chances of reaching azoospermia were 1.5 times higher in the subjects with more than 22 CAG triplet repeats. Conclusion： Partial suppression of spermatogenesis induced by 500 mg TU monthly injections is weakly influenced by hormonal and clinical features but not polymorphism in AR and FSHR genes.
