Interleukin-4 protects from chemotherapy-induced peripheral neuropathy in mice modal via the stimulation of IL-4/STAT6 signaling

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the possible role of IL-4 signaling pathway in vincristine-induced peripheral neuropathy. Methods: The mouse model of vincristine-induced peripheral neuropathy and interleukin (IL)-4 knockout mice were utilized to investigate the possible role of IL-4 signaling pathwa...

Effect of physical exercise on the renal structures of ovariectomized female LDL knockout mice

Int. j. morphol; 36 (1), 2018
SUMMARY: The reduction of ovarian function and a decrease in estrogen levels marked by menopause are related to increased susceptibility to develop dyslipidemia. These alterations in the lipid profile can have consequences in renal tissue and generate injuries that may progress to renal failure. The prac...

Moderate Continuous Aerobic Exercise Training Improves Cardiomyocyte Contractility in Β1 Adrenergic Receptor Knockout Mice

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: The lack of cardiac β1-adrenergic receptors (β1-AR) negatively affects the regulation of both cardiac inotropy and lusitropy, leading, in the long term, to heart failure (HF). Moderate-intensity aerobic exercise (MCAE) is recommended as an adjunctive therapy for patients w...

Soy milk versus simvastatin for preventing atherosclerosis and left ventricle remodeling in LDL receptor knockout mice

Braz. j. med. biol. res; 50 (3), 2017
Functional food intake has been highlighted as a strategy for the prevention of cardiovascular diseases by reducing risk factors. In this study, we compared the effects of oral treatment with soy milk and simvastatin on dyslipidemia, left ventricle remodeling and atherosclerotic lesion of LDL receptor kn...

Astragalus polysaccharides improve cardiomyopathy in STZ-induced diabetic mice and heterozygous (SOD2+/-) knockout mice

Braz. j. med. biol. res; 50 (8), 2017
Oxidative stress plays an important role in the development of diabetic cardiomyopathy. In the present study, we determined whether the effect of astragalus polysaccharides (APS) on diabetic cardiomyopathy was associated with its impact on oxidative stress. Streptozotocin (STZ)-induced diabetic mice and ...

Different engagement of TLR2 and TLR4 in Porphyromonas gingivalis vs. ligature-induced periodontal bone loss

Abstract This study was conducted to investigate the roles of different Toll-like receptor (TLR) signaling in Porphyromonas gingivalis (P. gingivalis)-induced and ligature-induced experimental periodontal bone resorption in mice. Wild-type (WT), TLR2 knockout (KO), TLR4KO, and TLR2&4 KO mice with C57...

Effect of chronic ingestion of wine on the glycemic, lipid and body weight homeostasis in mice

ABCD (São Paulo, Impr.); 29 (3), 2016
ABSTRACT Background: The health benefits associated with moderate wine consumption, as with ethanol and phenolic compounds, include different mechanisms still little understandable. Aim: Evaluate glycemic and weight variations, and the deposit of triglycerides, cholesterol and liver glycogen with red ...

Densidad asimétrica neuronal inter-hemisférica de la corteza insular en ratones FMR1 knock-out

Int. j. morphol; 32 (4), 2014
El síndrome X frágil en los seres humanos es causado por una mutación en el gen FMR1 y se asocia con grave retraso mental, hiperactividad y ansiedad. Hemos comparado ratones FMR1-KO con ratones Control en la densidad neuronal de la corteza insular, área del cerebro asociada con el procesamiento del d...

Estudos de características farmacológicas e de parâmetros de desenvolvimento e reproduçäo em camundongos transgênicos

1. - Estudo de Aspectos Farmacológicos do Ducto Deferente de camundongos Knockout Adra 2a-/-.Nossos resultados mostraram que a neurotransmissão no ducto deferente de camundongos knockout Adra2a-/-(que tiveram seus a2A-adrenoceptores deletados) foi afetada, com indicações de menor atividade do mecanis...

Patologia molecular do receptor de sulfoniluréia (SUR1)
Molecular pathology of sulfonylurea receptor (SUR1)

O receptor de sulfoniluréia (SUR1) é uma subunidade dos canais de potássio ATP-dependentes expressos nas células beta pancreáticas. O papel deste receptor nos mecanismos de secreçäo da insulina foi bem demonstrado após a descriçäo de que mutaçöes no seu gene codificador säo responsáveis pel...
