Abstract
Polycystic ovary syndrome (PCOS) is a complex reproductive, endocrine, and metabolic disorder in reproductive-age women. In order to explore the active metabolites of brown adipose tissue (BAT) transplantation in improving the reproductive and metabolic phenotypes in a PCOS rat model, the metabolites in the recipient's BAT were explored using the liquid chromatography-mass spectrometry technique. In total, 9 upregulated and 13 downregulated metabolites were identified. They were roughly categorized into 12 distinct classes, mainly including glycerophosphoinositols, glycerophosphocholines, and sphingolipids. Ingenuity pathway analysis predicted that these differentially metabolites mainly target the PI3K/AKT, MAPK, and Wnt signaling pathways, which are closely associated with PCOS. Furthermore, one of these differential metabolites, sphingosine belonging to sphingolipids, was randomly selected for further experiments on a human granulosa-like tumor cell line (KGN). It significantly accelerated the apoptosis of KGN cells induced by dihydrotestosterone. Based on these findings, we speculated that metabolome changes are an important process for BAT transplantation in improving PCOS. It might be a novel therapeutic target for PCOS treatment.

Abstract
Dehydroepiandrosterone (DHEA), mostly present as its sulfated ester (DHEA-S), is an anabolic hormone that naturally declines with age. Furthermore, it is the most abundant androgen and estrogen precursor in humans. Low plasma levels of DHEA have been strongly associated with obesity, insulin resistance, dyslipidemia, and high blood pressure, increasing the risk of cardiovascular disease. In this respect, DHEA could be regarded as a promising agent against metabolic syndrome (MetS) in postmenopausal women, since several age-related metabolic diseases are reported during aging. There are plenty of experimental evidences showing beneficial effects after DHEA therapy on carbohydrate and lipid metabolism, as well as cardiovascular health. However, its potential as a therapeutic agent appears to attract controversy, due to the lack of effects on some symptoms related to MetS. In this review, we examine the available literature regarding the impact of DHEA therapy on adiposity, glucose metabolism, and the cardiovascular system in the postmenopausal period. Both clinical studies and in vitro and in vivo experimental models were selected, and where possible, the main cellular mechanisms involved in DHEA therapy were discussed. Schematic representation showing some of the general effects observed after administration DHEA therapy on target tissues of energy metabolism and the cardiovascular system. ↑ represents an increase, ↓ represents a decrease, - represents a worsening and ↔ represents no change after DHEA therapy.

Abstract
AIMS To evaluate the acute effect of dehydroepiandrosterone (DHEA) on monoamine oxidase (MAO) activity in the corpus striatum (CS) and the nucleus accumbens (NAc) in vivo and in vitro. MAIN METHODS Male Wistar rats received an i.p. injection of DHEA (30, 60 and 120mg/kg) and MAO activity was assayed by formation of 4-hydroxyquinoline 2h later. For in vitro studies, DHEA (100nM-1mM) was added to brain tissue homogenates to assay MAO activity. KEY FINDINGS DHEA significantly reduced (-24%) total MAO activity in the NAc (F=8.5, p<0.001), but not in the CS, at 120mg/kg dose. No significant difference was observed when MAO A and MAO B activities were independently analyzed. When assayed in vitro, total MAO, MAO A and MAO B activities were reduced by DHEA to 55.7, 28.2 and 54.4% in the NAc and to 71.9, 44.2 and 61.2% in the CS, respectively (IC(50) 4.7-56.1microM). SIGNIFICANCE An inhibitory effect of DHEA on MAO activity may be involved in the antidepressant and neuroprotective effects of the steroid. Since MAO inhibition reduces neurodegeneration in clinical trials for Parkinson's disease, our results suggest that DHEA may be useful to treat depression and to prevent neuronal death in this disorder.

Abstract
It has been shown that the steroid dehydroepiandrosterone (DHEA) interacts with dopamine (DA) and serotonin (5-HT) neurotransmitter systems, which are involved in the pathophysiology of neurological and psychiatric diseases such as Parkinson's disease as well as mood and psychotic disorders. To explore if DHEA modulates DA and 5-HT metabolism we analyzed the content of both neurotransmitters and their metabolites in the rat corpus striatum (CS) and nucleus accumbens (NAc) 2 h after steroid administration (30, 60 and 120 mg/kg i.p.). DHEA treatment significantly reduced DA turnover (up to 33%) in the CS, but increased 5-HT turnover (up to 76%) in both regions. Those effects could be relevant to mood and neurodegenerative disorders.

Abstract
Dehydroepiandrosterone (DHEA) is synthesized in the brain and several studies have shown that this steroid is a modulator of synaptic transmission. The effect of DHEA, and its sulfate ester DHEAS, on glutamate and GABA neurotransmission has been extensively studied but some effects on other neurotransmitter systems, such as dopamine, serotonin and nitric oxide, have also been reported. This review summarizes studies showing the effect of DHEA and DHEAS on neurotransmitter systems at different levels (metabolism, release, reuptake, receptor activation), as well as the activation of voltage-gated ion channels and calcium homeostasis, showing the variety of effects that these steroids exert on those systems, allowing the discussion of its mechanisms of action and its relevance to psychiatric disorders.

Abstract
X-linked adrenoleukodystrophy (X-ALD) is a neurodegenerative disease caused by mutations in the ABCD1 gene, which encodes a peroxisomal ABC transporter, ALDP, supposed to participate in the transport of very long chain fatty acids (VLCFA). The adrenoleukodystrophy-related protein (ALDRP), which is encoded by the ABCD2 gene, is the closest homolog of ALDP and is considered as a potential therapeutic target since functional redundancy has been demonstrated between the two proteins. Pharmacological induction of Abcd2 by fibrates through the activation of PPARalpha has been demonstrated in rodent liver. DHEA, the most abundant steroid in human, is described as a PPARalpha activator and also as a prohormone able to mediate induction of several genes. Here, we explored the in vitro and in vivo effects of DHEA on the expression of peroxisomal ABC transporters. We show that Abcd2 and Abcd3 but not Abcd4 are induced in primary culture of rat hepatocytes by DHEA-S. We also demonstrate that Abcd2 and Abcd3 but not Abcd4 are inducible by an 11-day treatment with DHEA in the liver of male rodents but not in brain, testes and adrenals. Finally and contrary to Abcd3, we show that the mechanism of induction of Abcd2 is independent of PPARalpha.

Abstract
In response to lipopolysaccharide (LPS), macrophages secrete cytokines that transmit a message to the brain and induce sickness behavior. Because dehydroepiandrosterone (DHEA) and its sulfated ester (DHEA-S) reportedly improve mental health and modulate cytokine production, we hypothesized that DHEA-S administration would inhibit LPS-induced sickness behavior. Mice were provided drinking water with 0% or 0.01% DHEA-S for 2 weeks and then injected intraperitoneally with saline or LPS (1 microg). Sickness behavior was quantified using a social investigation paradigm, and DHEA-S in plasma and brain was determined at the study's end. DHEA-S did not affect water intake, food intake, or body weight during the 2-week period. As anticipated, LPS depressed social behavior. The maximum depression was observed 2 h postinjection, after which social investigation steadily increased until returning to baseline level at 8 h. DHEA-S did not mitigate the effects of LPS on social behavior even though DHEA-S in plasma and brain was increased 150- and 6-fold, respectively, in mice given DHEA-S. In a separate study, mice were given DHEA-S for 3 months and then challenged with LPS. Consistent with the first study, LPS reduced social behavior irrespective of DHEA-S treatment. However, 3 months administration of DHEA-S reduced the depression from baseline after injection of saline or LPS. DHEA-S in plasma and brain for mice given DHEA-S for 3 months was similar to that observed after 2 weeks. Collectively, these results suggest that DHEA-S has neuromodulatory effects but is ineffective at ameliorating LPS-induced sickness behavior.

Abstract
Dietary dehydroepiandrosterone (DHEA) inhibits the proliferation of syngeneic bone marrow cells (BMC) infused into lethally irradiated mice. Potential mechanisms for suppression of hematopoiesis were evaluated and the findings were as follows: (i) depletion of NK, T, B or macrophage cells failed to reverse suppression by DHEA; (ii) stem cell stimulation by erythropoietin, growth hormone, interleukin-2, Friend leukemia virus, or cyclophosphamide failed to reverse suppression; (iii) supplementation of fatty acids, mevalonate, or deoxyribonucleotides, which are dependent upon glucose-6-phosphate dehydrogenase function, did not enhance BMC growth in mice fed DHEA; (iv) DHEA downstream metabolites 4-androstenedione and 17beta-estradiol, as well as the synthetic steroid, 16alpha-chloroepiandrosterone (but not testosterone or 5-androstene-3beta,17beta-diol), also inhibited BMC growth. Tamoxifen antagonized the effects of 17beta-estradiol but not DHEA; (v) dietary DHEA causes hypothermia, but housing of DHEA-fed mice at 34 degrees C to maintain normal body temperature did not reverse suppression; (vi) DHEA leads to a decrease in food intake in rodents. Pair-feeding control diet to mice fed DHEA mimicked the effects of dietary DHEA; (vii) adrenalectomy and orchiectomy decrease the levels of stress and sex hormones, respectively. Neither procedure affected the ability of food restriction or DHEA feeding to inhibit hematopoiesis; (viii) growth of GR-3 NM pre-B leukemia cells in unirradiated mice was also suppressed by DHEA or food restriction. We conclude that DHEA, by reducing food intake in mice, inhibits bone marrow and leukemia cell growth. The precise mechanism(s) by which reduced food intake per se inhibits hematopoiesis is not known, but may involve an increased rate of cellular apoptosis.

Abstract
Hypothalamic neurotransmitter levels were compared between groups of Zucker rats. Animals were grouped by gender, phenotype and preference for dietary fat. Before sacrifice all animals consumed a standard rat chow diet and were fasted overnight. Five rats from each of eight groups were assayed. Hypothalamic regions (lateral, LH; ventromedial, VMH; paraventricular, PVN) and the raphe were isolated and analyzed for dopamine, norepinephrine, epinephrine, serotonin and 5-hydroxyindoleacetic acid. A factorial analysis of variance was used to compare the concentrations of these biogenic amines in the four regions across phenotypic, gender and fat preference profiles. No differences were demonstrated between groups based upon fat food preference. Epinephrine and 5-HIAA content varied between lean and obese animals but there were no differences in the content of serotonin, norepinephrine or dopamine. The results are consistent with the hypothesis that the obese animal eats more because it releases less of the satiety-inducing neurotransmitter serotonin in the hypothalamus.

Abstract
Dietary dehydroepiandrosterone (DHEA) reduces food intake in mice, and this response is under genetic control. Moreover, both food restriction and DHEA can prevent or ameliorate certain diseases and mediate other biological effects. Mice fed DHEA (0.45% w/w of food) and mice pair-fed to these mice (food restricted) for 8 weeks were tested for changes in body temperature. DHEA was more efficient than food restriction alone in causing hypothermia. DHEA injected intraperitoneally also induced hypothermia that reached a nadir at 1 to 2 hr, and slowly recovered by 20 to 24 hr. This effect was dose dependent (0.5-50 mg). Each mouse strain tested (four) was susceptible to this effect, suggesting that the genetics differ for induction of hypophagia and induction of hypothermia. Because serotonin and dopamine can regulate (decrease) body temperature, we treated mice with haloperidol (dopamine receptor antagonist), 5,7-dihydroxytryptamine (serotonin production inhibitor), or ritanserin (serotonin receptor antagonist) prior to injection of DHEA. All of these agents increased rather than decreased the hypothermic effects of DHEA. DHEA metabolites that are proximate (5-androstene-3beta, 17beta-diol and androstenedione) or further downstream (estradiol-17beta) were much less effective than DHEA in inducing hypothermia. However, the DHEA analog, 16alpha-chloroepiandrosterone, was as active as DHEA. Thus, DHEA administered parentally seems to act directly on temperature-regulating sites in the body. These results suggest that DHEA induces hypothermia independent of its ability to cause food restriction, to affect serotonin or dopamine functions, or to act via its downstream steroid metabolites.
