Dopa-testotoxicosis: disruptive hypersexuality in hypogonadal men with prolactinomas treated with dopamine agonists De Sousa SMC, Chapman IM, Falhammar H, Torpy DJ EBM Reviews - Cochrane Central Register of Controlled Trials Endocrine. 55(2):618-624, 2017. [Journal: Article] AN: CN-01327741 NEW Dopamine agonists are the first line of therapy for prolactinomas, with high rates of biochemical control and tumour shrinkage. Toxicity is considered to be low and manageable by switching of agents and dose reduction. Dopamine agonist-induced impulse control disorders are well Page 2 described in the neurology setting, but further data are required regarding this toxicity in prolactinoma patients. We performed a multicenter retrospective cohort study of eight men with prolactinomas and associated central hypogonadism. The eight men had no prior history of psychiatric disease, but each developed disruptive hypersexuality whilst on dopamine agonist therapy at various doses. Cabergoline, bromocriptine and quinagolide were all implicated. Hypersexuality had manifold consequences, including relationship discord, financial loss, reduced work performance, and illicit activity. We hypothesise that this phenomenon is due to synergy between reward pathway stimulation by dopamine agonists, together with rapid restoration of the eugonadal state after prolonged hypogonadism. We refer here to this distinct drug toxicity as 'dopa-testotoxicosis'. Given the profound impact in these patients and their families, cessation of dopamine agonists should be considered in men who develop hypersexuality, and pituitary surgery may be required to facilitate this. Awareness of this distinct impulse control disorder should enable further research into the prevalence, natural history and management of dopa- testotoxicosis. The condition is likely under-reported due to the highly personal nature of the symptoms and we suggest a simple written questionnaire to screen for hypersexuality and other behavioural symptoms within the first six months of dopamine agonist treatment.

Expression of hypothalamic-pituitary-gonadal axis-related hormone receptors in low-grade serous ovarian cancer (LGSC) Feng Z, Wen H, Ju X, Bi R, Chen X, Yang W, Wu X EBM Reviews - Cochrane Central Register of Controlled Trials Journal of ovarian research. 10(1) (no pagination):2017. [Journal: Article] AN: CN-01327789 NEW Background: The aim of our study was to investigate the clinical features and expression levels of hypothalamic-pituitary-gonadal axis-related hormone receptors in low-grade serous ovarian Page 3 cancer (LGSC). Methods: We retrospectively investigated the clinical features of 26 consecutive patients with LGSC who underwent primary staging or debulking surgery between April 2005 and June 2013 in our center; concomitant primary high-grade serous ovarian cancer (HGSC) patients were randomly selected at a 2:1 ratio for comparison. Tissue microarrays were constructed from the LGSC and HGSC specimens, and the expression levels of six hormone receptors in the hypothalamic pituitary-gonadal axis were analyzed by immunohistochemistry. Results: The median (range) age of patients with LGSC was 54 (27-77) years. According to the FIGO staging system, the cases were distributed as follows: stage I, 6 (23.1%); stage II, 0 (0%); stage III, 19 (73.1%); and stage IV, 1 (3.8%). The 2-year and 5-year overall survival rates for LGSC were 91.8% and 67.5%, respectively. The expression levels of the hormone receptors were as follows: ER, 80.8%; PR, 34.6%; AR, 53.8%; FSHR, 84.0%; LHR, 65.4%; and GnRHR, 100%. Hormone receptor-positive patients had a better prognosis compared with hormone receptor-negative patients, but the difference was not significant. Conclusions: Our study presented a higher overall survival rate and distinctive hormone receptor expression levels of LGSC patients compared with the HGSC cohort. Patients with positive hormone receptor expression tended to have a better prognosis than the corresponding hormone receptor negative patients. Copyright (C) 2017 The Author(s). Institution X.

Dopa-testotoxicosis: a novel drug toxicity of dopamine agonists in male prolactinoma patients De Sousa SMC, Chapman IM, Falhammar H, Torpy DJ EBM Reviews - Cochrane Central Register of Controlled Trials Clinical endocrinology. Conference: endocrine society of australia annual scientific meeting. 2016. Australia. Conference start: 20160821. Conference end: 20160824 Vol.86, pp.18, 2017. [Journal: Conference Abstract] AN: CN-01334018 NEW Background: Impulse control disorders (ICD) including gambling, hypersexuality, compulsive shopping and binge eating have recently been recognised as side effects of dopamine agonists Page 4 (DAs). The vast majority has been described in the treatment of Parkinson's disease and restless legs syndrome where pathological gambling is the predominant DA-associated ICD (1). Little is known about the nature of ICDs in the prolactinoma setting where endocrine factors, specifically testosterone fluctuations, may influence behaviour (2). Methods: We performed a multicenter retrospective cohort study of eight men who developed hypersexuality following initiation of DA therapy for prolactinomas. Results: The men had no prior history of psychiatric disease, but each developed disruptive hypersexuality with manifold consequences, including relationship discord, financial loss, reduced work performance, and illicit activity. Two men also developed pathological gambling. Cabergoline, bromocriptine and quinagolide were all implicated. The onset of hypersexuality ranged from days to years after DA commencement. Some men notably had normal pre-treatment testosterone levels, however these values were in the lower half of the reference range and rose into the upper half with DA initiation suggesting they had relative hypogonadism at baseline. Six men received no androgen replacement and increases in testosterone were solely attributable to DA therapy. Prolactin and testosterone consistently improved to be close or within the reference range by the time of symptom onset. Symptoms were reversible with DA cessation. Conclusions:

However, the role of kisspeptin signaling in testicular function is less clear. The testes are essential for male reproduction through their functions of spermatogenesis and steroidogenesis. Our review focused on the current literature investigating the distribution, regulation and effects of kisspeptin and its receptor (KISS1/KISS1R) within the testes of species studied to date. There is substantial evidence of localised KISS1/KISS1R expression and peptide distribution in the testes. However, variability is observed in the testicular cell types expressing KISS1/KISS1R. Evidence is presented for modulation of steroidogenesis and sperm function by kisspeptin signaling. However, the physiological importance of such effects, and whether these are paracrine or endocrine manifestations, remain unclear. Keywords: kisspeptin; kisspeptin receptor; spermatozoa; Leydig cells; Sertoli cells; testes; testosterone; LH; FSH; spermatogenesis 1. Introduction Kisspeptin is an established regulator of puberty onset [1,2], sexual maturation and adult reproductive activity [3].

Luteolin is one of the major bioactivity compositions in F. chrysanthemi Indici in JMT. There are some reports about pharmacokinetics of luteolin in extract of F. chrysanthemi and husks of peanut in normal rats, but it lacked pharmacokinetic information of luteolin residing in a Chinese herb compound prescription in hypertensive animal models. The present study aimed to develop a high-performance liquid chromatography with photodiode array detection (HPLC-DAD) method for determination of luteolin in rat plasma and for pharmacokinetic study after oral administration of JMT to spontaneous hypertensive rats (SHR) and normal Sprague Dawley (SD) rats. After oral administration of JMT to SHR and SD rats, respectively the content of luteolin in blood samples at different time points were determined by a reversed-phase high- performance liquid chromatography (RP-HPLC) coupled with liquid-liquid phase extraction.

  • Novel Mutations in ANOS1 and FGFR1 Genes Agnieszka Gach1* , Iwona Pinkier1, Maria Szarras-Czapnik2, Agata Sakowicz3 and Lucjusz Jakubowski1
    Gach et al. Reproductive Biology and Endocrinology (2020) 18:8 https://doi.org/10.1186/s12958-020-0568-6 RESEARCH Open Access Expanding the mutational spectrum of monogenic hypogonadotropic hypogonadism: novel mutations in ANOS1 and FGFR1 genes Agnieszka Gach1* , Iwona Pinkier1, Maria Szarras-Czapnik2, Agata Sakowicz3 and Lucjusz Jakubowski1 Abstract Background: Congenital hypogonadotropic hypogonadism (CHH) is a rare disease, triggered by defective GnRH secretion, that is usually diagnosed in late adolescence or early adulthood due to the lack of spontaneous pubertal development. To date more than 30 genes have been associated with CHH pathogenesis with X-linked recessive, autosomal dominant, autosomal recessive and oligogenic modes of inheritance. Defective sense of smell is present in about 50–60% of CHH patients and called Kallmann syndrome (KS), in contrast to patients with normal sense of smell referred to as normosmic CHH. ANOS1 and FGFR1 genes are all well established in the pathogenesis of CHH and have been extensively studied in many reported cohorts. Due to rarity and heterogenicity of the condition the mutational spectrum, even in classical CHH genes, have yet to be fully characterized. Methods: To address this issue we screened for ANOS1 and FGFR1 variants in a cohort of 47 unrelated CHH subjects using targeted panel sequencing. All potentially pathogenic variants have been validated with Sanger sequencing. Results: Sequencing revealed two ANOS1 and four FGFR1 mutations in six subjects, of which five are novel and one had been previously reported in CHH. Novel variants include a single base pair deletion c.313delT in exon 3 of ANOS1, three missense variants of FGFR1 predicted to result in the single amino acid substitutions c.331C > T (p.R111C), c.1964 T > C (p.L655P) and c.2167G > A (p.E723K) and a 15 bp deletion c.374_388delTGCCCGCAGACTCCG in exon 4 of FGFR1.

  • Antidepressant-Like Behavioral and Neurochemical Effects of the Citrus
    Available online at www.sciencedirect.com Life Sciences 82 (2008) 741–751 www.elsevier.com/locate/lifescie Antidepressant-like behavioral and neurochemical effects of the citrus-associated chemical apigenin ⁎ Li-Tao Yi, Jian-Mei Li, Yu-Cheng Li, Ying Pan, Qun Xu, Ling-Dong Kong State Key Laboratory of Pharmaceutical Biotechnology, School of Life Sciences, Nanjing University, Nanjing 210093, PR China Received 14 July 2007; accepted 16 January 2008 Abstract Apigenin is one type of bioflavonoid widely found in citrus fruits, which possesses a variety of pharmacological actions on the central nervous system. A previous study showed that acute intraperitoneal administration of apigenin had antidepressant-like effects in the forced swimming test (FST) in ddY mice. To better understand its pharmacological activity, we investigated the behavioral effects of chronic oral apigenin treatment in the FST in male ICR mice and male Wistar rats exposed to chronic mild stress (CMS). The effects of apigenin on central monoaminergic neurotransmitter systems, the hypothalamic–pituitary–adrenal (HPA) axis and platelet adenylyl cyclase activity were simultaneously examined in the CMS rats. Apigenin reduced immobility time in the mouse FST and reversed CMS-induced decrease in sucrose intake of rats. Apigenin also attenuated CMS-induced alterations in serotonin (5-HT), its metabolite 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA) levels and 5-HIAA/ 5-HT ratio in distinct rat brain regions. Moreover, apigenin reversed CMS-induced elevation in serum corticosterone concentrations and reduction in platelet adenylyl cyclase activity in rats. These results suggest that the antidepressant-like actions of oral apigenin treatment could be related to a combination of multiple biochemical effects, and might help to elucidate its mechanisms of action that are involved in normalization of stress- induced changes in brain monoamine levels, the HPA axis, and the platelet adenylyl cyclase activity.

Either insulin resistance or estrogen receptor (ER) defect is the initiator of pathologic processes and both of them may lead to breast cancer development. Primary insulin resistance induces hyperandrogenism and estrogen deficiency, but during these ongoing pathologic processes, ER defect also develops. Conversely, when estrogen resistance is the onset of hormonal and metabolic disturbances, initial counteraction is For personal use only. hyperestrogenism. Compensatory mechanisms improve the damaged reactivity of ERs; however, their failure leads to secondary insulin resistance. The final stage of both pathologic pathways is the breakdown of estrogen surveillance, leading to breast cancer development. Among pre- menopausal breast cancer cases, insulin resistance is the preponderant initiator of alterations with hyperandrogenism, which is reflected by the majority of studies suggesting a causal role of hyperandrogenism in breast cancer development. In the majority of postmenopausal cases, tumor development may also be initiated by insulin resistance, while hyperandrogenism is typi- cally coupled with elevated estrogen levels within the low postmenopausal hormone range.

While ovulation rate is the major determinant of 12 litter size in sheep, interactions among the conceptus, corpus luteum and endometrium are essential for 13 pregnancy success. Here, we performed a comparative transcriptome study by sequencing total mRNA from 14 corpus luteum (CL) collected during the preimplantation stage of pregnancy in Finnsheep, Texel and F1 15 crosses, and mapping the RNA-Seq reads to the latest Rambouillet reference genome. A total of 21,287 genes 16 were expressed in our dataset. Highly expressed autosomal genes in the CL were associated with biological 17 processes such as progesterone formation (STAR, CYP11A1, and HSD3B1) and embryo implantation (eg.

We hypothesized that serum and IT androstenedione (ADD) and IT dehydroepiandrosterone (DHEA) would be significantly suppressed by the adminis- tration of a GnRH antagonist and increased when stimulated by hCG, without a similar suppression of serum DHEA. Methods: We suppressed gonadotropins in 23 normal men with the GnRH antagonist acyline and randomly assigned them to one of four doses of hCG, 0, 15, 60, or 125 IU sc every other day for 10 d.

  • The Mechanism of Androgen Actions in PCOS Etiology
    medical sciences Review The Mechanism of Androgen Actions in PCOS Etiology Valentina Rodriguez Paris 1 and Michael J. Bertoldo 1,2,* 1 Fertility and Research Centre, School of Women’s and Children’s Health, University of New South Wales Sydney, NSW 2052, Australia 2 School of Medical Sciences, University of New South Wales Sydney, NSW 2052, Australia * Correspondence: [email protected] Received: 15 June 2019; Accepted: 20 August 2019; Published: 28 August 2019 Abstract: Polycystic ovary syndrome (PCOS) is the most common endocrine condition in reproductive-age women. By comprising reproductive, endocrine, metabolic and psychological features—the cause of PCOS is still unknown. Consequently, there is no cure, and management is persistently suboptimal as it depends on the ad hoc management of symptoms only. Recently it has been revealed that androgens have an important role in regulating female fertility. Androgen actions are facilitated via the androgen receptor (AR) and transgenic Ar knockout mouse models have established that AR-mediated androgen actions have a part in regulating female fertility and ovarian function. Considerable evidence from human and animal studies currently reinforces the hypothesis that androgens in excess, working via the AR, play a key role in the origins of polycystic ovary syndrome (PCOS). Identifying and confirming the locations of AR-mediated actions and the molecular mechanisms involved in the development of PCOS is critical to provide the knowledge required for the future development of innovative, mechanism-based interventions for the treatment of PCOS. This review summarises fundamental scientific discoveries that have improved our knowledge of androgen actions in PCOS etiology and how this may form the future development of effective methods to reduce symptoms in patients with PCOS.
