BACKGROUND: Vitamin is a well-known co-factor for many metabolic processes and its roles in fertility and follicular growth have been studied. Vitamin supplementation is frequently achieved by daily ingestion in the form of a complex capsule. However, the role of single and complex vitamins in in vitro maturation of murine follicles is not fully elucidated. METHODS: In this study, we evaluated the effects of two forms of vitamins. Pure L-ascorbic acid, and multi-vitamin (vitamin C+vitamin B complex) was treated at two different concentrations (50 and 100 µg/ml), to pre-puberty murine follicles during in vitro maturation. To determine the specific stage of growth that is affected by treatment with vitamins, the vitamins were treated from day 0, 4, 9, and 13. Growth of each follicle was assessed by measuring diameters of whole expanded area and of the granulosa cells. Expression of follicular and oocyte growth-related genes and the effect of vitamin on the viability of follicles was assessed using senescence associated β-galactosidase staining. RESULTS: Treatment with vitamins promoted the in vitro growth of murine follicles and the upregulated the expression of granulosa cell- and oocyte-specific genes such as BMP15, Fsh receptor, and GDF9. The proliferation of the granulosa cells was enhanced by the treatment of vitamin. Fifty µg/ml concentration vitamin showed greater effects compared to higher concentration. The viability of in vitro grown follicles was also significantly improved in vitamin-treated follicles. The effects of single L-ascorbic acid and complex vitamin were not significantly different to those of day 4 and day 9 follicles. Vitamins promoted murine follicle development in vitro with different effects on specific growth stage. CONCLUSION: Supplementation of vitamins during in vitro maturation of murine follicles is an efficient strategy for in vitro expansion of follicular cells. These results could be customized to the sophisticated culture of follicles retrieved from aged or cancer-survived female that contain smaller number of follicles with reduced potential to develop into mature follicles.

Going back to basics prior to mentioning the use of antipsychotics in patients with pain, the International Association for the Study of Pain (IASP) definition of pain can be summarized as an unpleasant experience, composed of sensory experience caused by actual tissue damage and/or emotional experience caused by potential tissue damage. Less used than antidepressants, antipsychotics have also been used for treating this unpleasant experience as adjuvant analgesics without sufficient evidence from research. Because recently developed atypical antipsychotics reduce the adverse reactions of extrapyramidal symptoms, such as acute dystonia, pseudo-parkinsonism, akathisia, and tardive dyskinesia caused by typical antipsychotics, they are expected to be used more frequently in various painful conditions, while increasing the risk of metabolic syndromes (weight gain, diabetes, and dyslipidemia). Various antipsychotics have different neurotransmitter receptor affinities for dopamine (D), 5-hydroxytryptamine (5-HT), adrenergic (α), histamine (H), and muscarinic (M) receptors. Atypical antipsychotics antagonize transient, weak D₂ receptor bindings with strong binding to the 5-HT(2A) receptor, while typical antipsychotics block long-lasting, tight D₂ receptor binding. On the contrary, antidepressants in the field of pain management also block the reuptake of similar receptors, mainly on the 5-HT and, next, on the norepinephrine, but rarely on the D receptors. Antipsychotics have been used for treating positive symptoms, such as delusion, hallucination, disorganized thought and behavior, perception disturbance, and inappropriate emotion, rather than the negative, cognitive, and affective symptoms of psychosis. Therefore, an antipsychotic may be prescribed in pain patients with positive symptoms of psychosis during or after controlling all sensory components.

The luteinizing hormone-releasing hormone/androgen receptor (LHRH/AR) pathway is a promising treatment target in a subgroup of female patients with triple-negative breast cancer (TNBC). However, very little is known about the efficacy of this strategy in male patients with TNBC. In this report, we describe a male patient with AR-positive TNBC who was successfully treated using an LHRH agonist after pretreatment with several lines of chemotherapy and achieved a durable response. We also review the existing evidence supporting LHRH- and AR-targeted therapy for this rare disease.

Methylphenidate (MPH) is the most preferred drug for treatment of the attention deficit hyperactivity disorder (ADHD). Here, we aimed to discuss the possible effects and mechanisms of MPH on precocious puberty (PP) via a case series with seven children who had normal body mass index. In this case series we evaluated seven children with ADHD, who had received MPH for at least 6 months (0.5 mg/kg/dose three times a day, maximum 60 mg) and admitted to Department of Pediatric Endocrinology with PP symptoms. The mean age was 8.16 years. Basal hormonal levels (luteinizing hormone [LH], follicle stimulating hormone, and estrogen/testosterone) were within normal range. Results of LH-releasing hormone stimulation tests demonstrated central pubertal responses. Glutamine, dopamine and noradrenaline are most important excitatory neurotransmitters that have a role at the beginning of puberty. The effect of MPH, cumulating dopamine and noradrenaline in the synaptic gap could be associated with the acceleration of puberty with the excitatory effect of dopamine’s gonadotropin-releasing hormone (GnRH) release, excitatory effect of noradrenaline’s GnRH release and the disappearance of GnRH receptor expression suppressor effect on prolactin disinhibitory effect.

OBJECTIVE: To investigate the expression of androgen receptor (AR) and its correlation with disease status and survival outcome in uterine leiomyosarcoma with other hormone receptors. METHODS: The medical records and paraffin blocks of 42 patients were reviewed. The immunohistochemical expression of AR, estrogen receptor (ER), progesterone receptor (PR), gonadotropin releasing hormone (GnRH), and cytochrome P450, family 19, subfamily A, polypeptide 1 (CYP19A1) were assessed using tissue microarray. RESULTS: In total, AR expression was observed in 11 patients (26.2%). International Federation of Gynecology and Obstetrics (FIGO) stage and AR were independent factors for disease-free survival (DFS) in multivariate regression analysis (odds ratio [OR]=5.8; 95% confidence interval [CI]=1.2–28.4 and OR=0.2; 95% CI=0.05–0.90; p=0.029 and 0.032, respectively). There were no deaths in the AR expression group, whereas the 5-year overall survival (OS) was 54.8% in the no expression group (p=0.014). Co-expression of ER and/or PR with AR was associated with significantly better 5-year DFS and OS than those with negative AR (72.7% vs. 28.6% and 100% vs. 64.3%; p=0.020 and 0.036, respectively). AR may be an independent prognostic marker regardless of ER/PR. CONCLUSION: AR can be a potential prognostic biomarker in uterine leiomyosarcoma.

At present, there is no reliable in vitro assembled prepubertal testis-like biomimetic organ culture system designed to assess the functional effects of human gonadotropins on Sertoli and Leydig cells. Spermatogenesis is regulated by endocrine, paracrine, and juxtacrine factors (testicular cross-talk), mainly orchestrated by gonadotropins such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) that play a pivotal role by stimulating Leydig and Sertoli cells, respectively. The aim of our study was to set up an in vitro prepubertal porcine bioengineered construct as a new model for experimental studies on reassembled Sertoli and Leydig cells. We have evaluated Sertoli and Leydig cells obtained from 15- to 20-day-old neonatal pig testes in terms of purity and function. Subsequently, purified Sertoli and enriched Leydig cells were subjected to coincubation to obtain an in vitro prepubertal porcine testis-like culture system. We performed enzyme-linked immunosorbent assay (ELISA) for anti-Müllerian hormone (AMH), inhibin B, and testosterone secretion in the medium, and Real-Time PCR analysis of AMH, inhibin B, FSH-r, aromatase, LHr, and 3β-HSD mRNA expression levels. This in vitro testis-like system was highly responsive to the effects of human gonadotropins and testosterone. AMH mRNA expression and secretion declined, and inhibin-B increased, while FSH-receptor expression was downregulated upon FSH/LH exposure/treatment. Finally, the production of testosterone was increased selectively upon LH treatment. In summary, our proposed model could help to better determine the action of human gonadotropins on Sertoli and Leydig cells. The potential usefulness of the system for shedding light into male infertility-related issues is evident.

The aim of the study was to provide a descriptive analysis of familial male-limited precocious puberty (FMPP), which is a rare inherited disease caused by heterozygous constitutively activating mutations of the luteinizing hormone/choriogonadotropin receptor gene (LHCGR). The patient was a ten-month-old boy, presenting with penile enlargement, pubic hair formation, and spontaneous erections. Based on the clinical manifestations and laboratory data, including sexual characteristics, serum testosterone levels, GnRH stimulation test, and bone age, this boy was diagnosed with peripheral precocious puberty. Subsequently the precocious puberty-related genes were analyzed by direct DNA sequencing of amplified PCR products from the patient and his parents. Genetic analysis revealed a novel heterozygous missense mutation c.1732G>C (Asp578His) of the LHCGR gene exon11 in the patient, which had never been reported. His parents had no mutations. After combined treatment with aromatase inhibitor letrozole and anti-androgen spironolactone for six months, the patient's symptoms were controlled. The findings in this study expand the mutation spectrum of the LHCGR gene, and provide molecular evidence for the etiologic diagnosis as well as for the genetic counseling and prenatal diagnosis in the family.

OBJECTIVETo explore the genetic etiology for two Chinese families affected with hypergonadotropic amenorrhea and normal number of antral follicles.
METHODSPeripheral venous blood samples were collected from the families for the extraction of genomic DNA. Mutations of FSHR and LHCGR genes were screened using PCR and Sanger sequencing. Suspected pathogenic mutations were verified in other members of the families. Bioinformatics software and NCBI were used to analyze the pathogenicity of the mutations.
RESULTSTwo previously unreported homozygous mutations, c.419delA and c.1510C>T of the FSHR gene were found in the probands of family I and II, respectively. Pedigree and bioinformatics analysis suggested that both mutations were pathogenic. Literature review suggested that both families were affected with resistant ovary syndrome rather than premature ovarian failure.
CONCLUSIONTwo novel mutations of the FSHR gene have been identified, which have enriched the spectrum of FSHR gene mutations and provided a basis for genetic counseling and direction for reproduction.

OBJECTIVE: The aim of this study was to evaluate the effect of short-term use of selective progesterone receptor modulator (SPRM) or gonadotropin-releasing hormone (GnRH) agonist on uterine fibroid shrinkage among Korean women. METHODS: This retrospective study involved 101 women with symptomatic uterine fibroids who received ulipristal acetate (SPRM, n=51) and leuprolide acetate (GnRH agonist, n=50) for 3 months between November 2013 and February 2015. The fibroid volume was measured both before and after treatment using ultrasonography, computed tomography, and magnetic resonance imaging. The outcomes were compared between the SPRM and GnRH agonist groups. RESULTS: The median rate of fibroid volume reduction after SPRM treatment was 12.4% (IQR −14.5% to 40.5%) which was significantly lower than the reduction rate observed after GnRH agonist treatment (median 34.9%, IQR 14.7% to 48.6%, P=0.004). 19 of 51 (37.3%) patients with SPRM treatment did not show any response of volume shrinkage, while 7 of 50 (14.0%) women with GnRH agonist showed no response (P=0.007). CONCLUSION: Short-term SPRM treatment yields lower volume reduction than GnRH agonist treatment in Korean women with symptomatic fibroids. Further large-scale randomized trials are needed to confirm our findings.
