1. Obesity care: more urgent than ever
ABSTRACT Deleterious effects of free fatty acids, FFAs, on insulin sensitivity are observed in vivo studies in humans. Mechanisms include impaired insulin signaling, oxidative stress, inflammation, and mitochondrial dysfunction, but the effects on insulin secretion are less well known. Our aim was to review the relationship of increased FFAs with insulin res

2. Effect of free fatty acids on insulin secretion, insulin sensitivity and incretin effect – a narrative review
ABSTRACT Deleterious effects of free fatty acids, FFAs, on insulin sensitivity are observed in vivo studies in humans. Mechanisms include impaired insulin signaling, oxidative stress, inflammation, and mitochondrial dysfunction, but the effects on insulin secretion are less well known.

3. Biochemical and Molecular Mechanisms of Glucose Uptake Stimulated by Physical Exercise in Insulin Resistance State: Role of Inflammation
Resumo A obesidade associada à inflamação sistêmica induz resistência à insulina (RI), com consequente hiperglicemia crônica. Este processo envolve o aumento na liberação de citocinas pró-inflamatórias, ativação da enzima c-Jun N-terminal cinase (JNK), do fator nuclear kappa-B (NF-κB) e dos receptores do tipo Toll 4 (TLR4). Dentre as ferramenta

4. Identification of novel mutations of Insulin Receptor Substrate 1 (IRS1) in tumor samples of non-small cell lung cancer (NSCLC): Implications for aberrant insulin signaling in development of cancer
Abstract Lung cancer is the leading cause of cancer-related death, and NSCLC constitutes nearly 85%–90% of all cases. The IRS proteins function as adaptors and transmit signals from multiple receptors. Upon binding of insulin to the insulin receptor (IR), IRS1 is phosphorylated at several YXXM motifs creating docking sites for the binding of PI3Kp85, which

5. Insulin Substrate Receptor (IRS) proteins in normal and malignant hematopoiesis
The insulin receptor substrate (IRS) proteins are a family of cytoplasmic proteins that integrate and coordinate the transmission of signals from the extracellular to the intracellular environment via transmembrane receptors, thus regulating cell growth, metabolism, survival and proliferation. The PI3K/AKT/mTOR and MAPK signaling pathways are the best-charac

6. Dipyrone in association with atropine inhibits the effect on gastric emptying induced by hypoglycemia in rats
Atropine (AT) and dipyrone (Dp) induce a delay of gastric emptying (GE) of liquids in rats by inhibiting muscarinic receptors and activating β2-adrenergic receptors, respectively. The objective of the present study was to determine the effects of pretreatment with AT and Dp, given alone or in combination, on the effect of hypoglycemia in the liquid GE in ra

7. The role of melatonin in diabetes: therapeutic implications
Melatonin referred as the hormone of darkness is mainly secreted by pineal gland, its levels being elevated during night and low during the day. The effects of melatonin on insulin secretion are mediated through the melatonin receptors (MT1 and MT2). It decreases insulin secretion by inhibiting cAMP and cGMP pathways but activates the phospholipaseC/IP3 path

8. Prevalence of the rs1801282 single nucleotide polymorphism of the PPARG gene in patients with metabolic syndrome
Objective This study aimed to get the genotypic and allelic frequencies of rs1801282 in 179 volunteer donors and 154 patients with Metabolic syndrome (MetS) in Brasilia, Brazil and also examine the association with anthropometric, biochemical and hemodynamic variables in the latter group. MetS comprises a group of diseases resulting from insulin resistance,

9. Papel anti-inflamatório da adiponectina e da interleucina-10 em modelos clínico e experimental de obesidade. / Role anti-inflammatory of adiponectin and interleukin-10 in obesity model clinical and experimental
Objetivo: Verificar os efeitos anti-inflamatórios da adiponectina e da interleucina 10 em modelos clínico e experimental de obesidade. O estudo foi dividido em duas etapas: clínico com adolescentes obesos submetidos à terapia de redução de peso interdisciplinar por 1 ano; e experimental in vitro, com adipócitos 3T3-L1. No estudo clínico, foram sujeit

10. Resposta à angiotensina II em artérias mesentéricas de resistência na obesidade: participação das MAPKs. / Differential participation of MAPKs in angiotensin II-induced contraction in obesity.
A angiotensina II (AngII) pode ativar as vias de sinalização das proteínas quinases ativadas por mitógenos (MAPKs). Investigamos o papel da obesidade e das MAPKs na resposta à AngII em ratos obesos por injeção de glutamato monossódico (Ob). Artérias mesentéricas de resistência com endotélio intacto e não as artérias sem endotélio, isoladas de

11. Dieta hiperlipídica e envelhecimento modificam a sensibilidade à insulina e a expressão das proteinas relacionadas à via intracelular da insulina em hipotálamo de camundongos fêmeas. / High-fat diet and aging impair insulin sensibility and intracellular insulin signaling proteins in hypothalamus of female mice.
Em machos, tanto o envelhecimento quanto a obesidade induzida por dieta hiperlipídica (DHL) apresentam defeitos na ação insulínica, no entanto há carência de informações sobre fêmeas. Avaliamos a sensibilidade à insulina, tolerância à glicose, o padrão estral e a expressão de proteínas da via insulínica em hipotálamo e músculo de fêmeas C5

12. Vias de sinalização intracelular envolvidas no efeito proliferativo de relaxina em células de sertoli / Intracelular signaling pathways involved in the proliferative effect of relaxin in rat Sertoli cells
Relaxin is an insulin-related peptide that activates the G-protein coupled receptor RXFP1. Although relaxin plays an important role in female reproduction its physiological role in the male reproductive system is still unclear. We have previously demonstrated that relaxin and RXFP1 are expressed in testis (FILONZI et al., 2007; CARDOSO et al., 2010). Both re
