Leptin and hypothalamic gene expression in early- and late-maturing Bos indicus Nellore heifers
Provedor de dados: 74
Autores: Vaiciunas,Aline; Coutinho,Luiz L.; Meirelles,Flávio V.; Pires,Alexandre V.; Silva,Luis Felipe P.
We investigated wether early-maturing or late-maturing Bos indicus Nellore heifers produced more leptin mRNA in adipose tissues and altered expression of hypothalamic genes related to leptin signaling. Six prepubertal and six pubertal heifers aged about 34 months and weighing 280 kg to 300 kg each were selected from a population of 100 Nellore heifers. Real-time PCR was used to quantify the expression of the leptin gene (LEP) in adipose tissues and the long isoform of the leptin receptor gene (Ob-Rb), the NK2 homeobox 1 hypothalamic marker gene NKX2-1, the suppressor of cytokine signaling 3 gene (SOCS-3), the neuropeptide Y genes (NPY) and the NPY G-protein coupled receptor genes NPY-Y1 and NPY-Y4 in the hypothalamus. Heifers attaining puberty earlier...

Economic Value of Selecting and Marketing Cattle by Leptin Genotype
Provedor de dados: 31
Autores: Lusk,   Jayson L.
Recent research has identified genetic diversity in the ability of animals to manufacture and recognize leptin, a protein that regulated appetite and weight. This paper determines the economic value of using information on leptin genotype to select and manage beef cattle. Results reveal that the economic value of using genotypic information to sort cattle by optimal endpoint is only about $2/head for steers and $1/head for heifers; however, the value of using genotypic information to optimally select and feed only certain genotypes is $23/head for steers and $28/head for heifers. The difference in per head profit between the best and worst performing genotype is over $28 on the date the cattle were actually marketed and increases to $60 if each genotype is...

Microcirculation in obesity: an unexplored domain
Provedor de dados: 42
Autores: Wiernsperger,Nicolas; Nivoit,Pierre; Bouskela,Eliete.
Obesity is traditionally linked to diabetes and cardiovascular diseases. Very recent experimental, clinical and epidemiological, sometimes provocative, data challenge this automaticity by showing that not the amount but the distribution of fat is the important determinant. Moderate abdominal fat accumulation may thus be more harmful than even consequent overweight. In view of the worldwide burden of obesity, factors leading to it in children and young adults must urgently be identified. Since obesity is a very complex cardiometabolic situation, this will require to focus investigations on uncomplicated obese subjects and adequate animal models. The recent discovery of intergenerational transmissions of obesity risk factors and also the key role played by...

The p. N103K mutation of leptin (LEP) gene and severe early onset obesity in Pakistan
Provedor de dados: 48
Autores: Shabana,; Hasnain,Shahida.
BACKGROUND: Obesity is a complex disorder and has been increasing globally at alarming rates including Pakistan. However, there is scarce research on understanding obesity genetics in Pakistan. Leptin is a hormone secreted by adipocytes in response to satiety and correlates with body weight. Any mutations in the LEP gene have an adverse effect on energy regulation pathway and lead to severe, early onset obesity. To date, only eight mutations have been described in the LEP gene of which p. N103K is one. METHODS: We aimed to analyze the prevalence of this mutation in Pakistani subjects. A total of 475 subjects were genotyped by PCR-RFLP analysis and their serum profiling was done. RESULTS: Results showed that this mutation was present only in one male child...

Secretory Patterns of Leptin and Luteinizing Hormone in Food-Restricted Young Female Sheep
Provedor de dados: 48
Autores: RECABARREN,SERGIO E; LOBOS,ALEJANDRO; TORRES,VERÓNICA; OYARZO,ROBERTO; SIR-PETERMANN,TERESA.
Leptin, the product of the ob gene, has been proposed as a metabolic signal that regulates the secretion of GnRH/LH. This may be critical during prepubertal development to synchronize information about energy stores and the secretion of GnRH/LH. This study aimed to assess the effect of food restriction on the episodic secretion of leptin and LH in young female sheep. Five 20-week-old prepubertal females were fed a low-level diet for 10 weeks to maintain the body weight. Control females of the same age received food ad libitum. Blood samples were collected at 10-min intervals for six hours at 20, 26, and 30 weeks of age, and plasma leptin, LH, insulin and cortisol concentrations were measured. In the control group, no changes were found in pulsatile LH...

Role of sympathetic nervous system and neuropeptides in obesity hypertension
Provedor de dados: 56
Autores: Hall,J.E.; Brands,M.W.; Hildebrandt,D.A.; Kuo,J.; Fitzgerald,S.
Obesity is the most common cause of human essential hypertension in most industrialized countries. Although the precise mechanisms of obesity hypertension are not fully understood, considerable evidence suggests that excess renal sodium reabsorption and a hypertensive shift of pressure natriuresis play a major role. Sympathetic activation appears to mediate at least part of the obesity-induced sodium retention and hypertension since adrenergic blockade or renal denervation markedly attenuates these changes. Recent observations suggest that leptin and its multiple interactions with neuropeptides in the hypothalamus may link excess weight gain with increased sympathetic activity. Leptin is produced mainly in adipocytes and is believed to regulate energy...

Serum leptin concentration during puberty in healthy nonobese adolescents
Provedor de dados: 56
Autores: Brandão,C.M.A.; Lombardi,M.T.; Nishida,S.K.; Hauache,O.M.; Vieira,J.G.H.
Data obtained during the past five years have indicated that there are important age- and gender-based differences in the regulation and action of leptin in humans. To study the physiological changes of leptin during puberty in both sexes, and its relationship with body composition and sexual maturation, we measured leptin concentrations in 175 healthy adolescents (80 girls, 95 boys, 10-18 years of age), representing all pubertal stages. We excluded individuals with a body mass index (BMI) below the 5thor above the 95th percentile relative to age. Serum concentrations of leptin were determined by a monoclonal antibody-based immunofluorimetric assay, developed in our laboratory. Body composition was determined by dual-energy X-ray absorptiometry. Pubertal...

Leptin is not associated independently with hypertension in Japanese-Brazilian women
Provedor de dados: 56
Autores: Almeida-Pititto,B.; Gimeno,S.G.A.; Freire,R.D.; Ribeiro-Filho,F.F.; Ferreira,S.R.G.
We evaluated the relationship of leptin with hypertension adjusted for body mass index (BMI) and/or waist circumference in a population of Japanese-Brazilian women aged  &gt; or = 30 years with centrally distributed adiposity. After excluding diabetic subjects, the study subjects - who participated in a population-based study on the prevalence of metabolic syndrome - showed prevalence rates of obesity (BMI  &gt; or = 25 kg/m²) and central adiposity (waist  &gt; or = 80 cm) of 32.0 and 37.8%, respectively. The hypertensive group (N = 162) was older, had higher BMI (24.9 ± 4.2 vs 23.3 ± 3.4 kg/m², P &lt; 0.001), waist circumference (81.1 ± 10.1 vs 76.3 ± 8.2 cm, P &lt; 0.001) and insulin levels (8.0 ± 6.2 vs 7.1 ± 4.9 µU/mL, P &lt; 0.05) than the...

Behavioral changes induced by cocaine in mice are modified by a hyperlipidic diet or recombinant leptin
Provedor de dados: 56
Autores: Erhardt,E.; Zibetti,L.C.E.; Godinho,J.M.; Bacchieri,B.; Barros,H.M.T.
The objective of the present study was to determine if the acute behavioral effects of cocaine acutely administered intraperitoneally (ip) at doses of 5, 10 and 20 mg/kg on white male CF1 mice, 90 days of age, would be influenced by leptin acutely administered ip (at doses of 5, 10 and 20 µg/kg) or by endogenous leptin production enhanced by a high-fat diet. The acute behavioral effects of cocaine were evaluated in open-field, elevated plus-maze and forced swimming tests. Results were compared between a group of 80 mice consuming a balanced diet and a high-fat diet, and a group of 80 mice fed a commercially available rodent chow formula (Ralston Purina) but receiving recombinant leptin (rLeptin) or saline ip. Both the high-fat-fed and rLeptin-treated mice...

Influence of dexamethasone and weight loss on the regulation of serum leptin levels in obese individuals
Provedor de dados: 56
Autores: Lerario,D.D.G.; Ferreira,S.R.G.; Miranda,W.L.; Chacra,A.R.
The adipocyte hormone leptin is thought to serve as a signal to the central nervous system reflecting the status of fat stores. Serum leptin levels and adipocyte leptin messenger RNA levels are clearly increased in obesity. Nevertheless, the factors regulating leptin production are not fully understood. The aim of this study was to determine the effects of in vivo administration of the synthetic glucocorticoid dexamethasone and weight loss on serum leptin levels in two independent protocols. Twenty-five obese subjects were studied (18 women and 7 men, mean age 26.6 ± 6 years, BMI 31.1 ± 2.5 kg/m², %fat 40.3 ± 8.3) and compared at baseline to 22 healthy individuals. Serum levels of leptin, insulin, proinsulin and glucose were assessed at baseline and after...

Previous studies have reported on the glucose and lipid-lowering effects of ferulic acid (FA) but its anti-obesity potential has not yet been firmly established. This study investigated the possible anti-obesitogenic effects of FA in mice fed a high-fat diet (HFD) for 15 weeks. To assess the antiobesity potential of FA, 32 male Swiss mice, weighing 20–25 g (n=6–8 per group) were fed a normal diet (ND) or HFD, treated orally or not with either FA (10 mg/kg) or sibutramine (10 mg/kg) for 15 weeks and at the end of this period, the body weights of animals, visceral fat accumulation, plasma levels of glucose and insulin hormone, amylase and lipase activities, the satiety hormones ghrelin and leptin, and tumor necrosis factor-α (TNF-α) and monocyte...

Pivotal role of leptin in insulin effects
Provedor de dados: 56
Autores: Ceddia,R.B.; William Jr.,W.N.; Lima,F.B.; Carpinelli,A.R.; Curi,R.
The OB protein, also known as leptin, is secreted by adipose tissue, circulates in the blood, probably bound to a family of binding proteins, and acts on central neural networks regulating ingestive behavior and energy balance. The two forms of leptin receptors (long and short forms) have been identified in various peripheral tissues, a fact that makes them possible target sites for a direct action of leptin. It has been shown that the OB protein interferes with insulin secretion from pancreatic islets, reduces insulin-stimulated glucose transport in adipocytes, and increases glucose transport, glycogen synthesis and fatty acid oxidation in skeletal muscle. Under normoglycemic and normoinsulinemic conditions, leptin seems to shift the flux of metabolites...

Estradiol participates in the control of energy homeostasis, as demonstrated by an increase in food intake and in body weight gain after ovariectomy in rats. In the present study, female Wistar rats (200-230 g, N = 5-15 per group), with free access to chow, were individually housed in metabolic cages. We investigated food intake, body weight, plasma leptin levels, measured by specific radioimmunoassay, and the hypothalamic mRNA expression of orexigenic and anorexigenic neuropeptides, determined by real-time PCR, in ovariectomized rats with (OVX+E) and without (OVX) estradiol cypionate treatment (10 µg/kg body weight, sc, for 8 days). Hormonal and mRNA expression were determined at pre-feeding and 4 h after food intake. OVX+E rats showed lower food intake,...

Positive correlation of serum leptin with estradiol levels in patients with polycystic ovary syndrome
Provedor de dados: 56
Autores: Mendonça,H.C.; Montenegro Junior,R.M.; Foss,M.C.; Silva de Sá,M.F.; Ferriani,R.A.
Patients with polycystic ovary syndrome (PCOS) usually are obese, insulin resistant and hyperinsulinemic. The known association between leptin, obesity andinsulin action suggests that leptin may have a role in PCOS but this has only been addressed peripherally. This study was designed to assess the relationship between serum leptin and the anthropometric, metabolic and endocrine variables of obese (body mass index, BMI ³30 kg/m²) and non-obese (BMI &lt;30 kg/m²) PCOS patients. Twenty-eight PCOS patients and 24 control women subdivided into obese and non-obese groups were evaluated. Leptin, androgens, lipids, gonadotrophins and insulin-glucose response to the oral glucose tolerance test were measured by radioimmunoassay in all participants. The assays were...

Leptin is produced primarily by adipocytes. Although originally associated with the central regulation of satiety and energy metabolism, increasing evidence indicates that leptin may be an important mediator in cardiovascular pathophysiology. The aim of the present study was to investigate plasma leptin levels in patient with Chagas' heart disease and their relation to different forms of the disease. We studied 52 chagasic patients and 30 controls matched for age and body mass index. All subjects underwent anthropometric, leptin and N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements and were evaluated by echocardiography, 12-lead electrocardiogram (ECG), and chest X-ray.

Malnutrition during lactation as a metabolic imprinting factor inducing the feeding pattern of offspring rats when adults: The role of insulin and leptin
Provedor de dados: 56
Autores: Moura,A.S.; Franco de Sá,C.C.N.; Cruz,H.G.; Costa,C.L.
The aim of the present study was to determine the impact of malnutrition during early postnatal life and the feeding pattern of rat offspring when adults (2 months and 1 year old). In comparison with rats normally fed during lactation, we observed that adult offspring displayed a faster process of feeding reduction when a protein-free diet was offered. In addition, we studied the concentration of insulin and leptin in the lactating pups (10 days) and when these offspring became adult after the onset of a new feeding pattern induced by the protein-free diet. When the diet was changed at 60 days, the offspring malnourished during lactation displayed, after 3 days, a food intake reduction around 41.4 vs 14.2% of the control group. At 10 days of life, plasma...

Leptin and adiponectin in the female life course
Provedor de dados: 56
Autores: Lecke,S.B.; Morsch,D.M.; Spritzer,P.M.
Adipose tissue secretes a variety of adipokines, including leptin and adiponectin, which are involved in endocrine processes regulating glucose and fatty metabolism, energy expenditure, inflammatory response, immunity, cardiovascular function, and reproduction. The present article describes the fluctuations in circulating leptin and adiponectin as well as their patterns of secretion in women from birth to menopause. During pregnancy, leptin and adiponectin seem to act in an autocrine/paracrine fashion in the placenta and adipose tissue, playing a role in the maternal-fetal interface and contributing to glucose metabolism and fetal development. In newborns, adiponectin levels are two to three times higher than in adults. Full-term newborns have...

Provedor de dados: 60
Autores: Mohafez,Omar Mahmoud; Alhaider,Ibrahim Abdelrahman; Shehata,Tamer Mohamed; Mohamed,Maged Elsayed.
Obesity represents a major challenge to the pharmaceutical community due to the minimal availability of anti-obesity drugs and the drawbacks of current weight-loss agents. The study described herein presents lupine oil, in two pharmaceutical formulations, as a potential anti-obesity agent via its effect on different physiological, biochemical, and hormonal parameters. Rats were divided into two groups; one group was continued on a standard commercial rodent diet and served as the non-obese control. The other group was fed a high-fat diet for 7 weeks to prepare an obese rat model. Then, the obese rats were divided into groups to receive 100 mg/kg of the crude lupine oil or nanoemulsion for 10 or 20 days. Lupine oil showed a potent body weight-reducing...
