OBJECTIVE The effects of high-refined carbohydrate-containing diet (HC) on inflammatory parameters and metabolic disarrangement of adipose tissue are poorly understood. The aim of this study was to evaluate the timing and progression of metabolic and inflammatory dysfunction induced by HC diet in mice. DESIGN AND METHODS BALB/c mice were fed chow or HC(More)
Irinotecan is a useful chemotherapeutic for the treatment of various cancers. Irinotecan treatment is associated with mucositis, which clearly limits the use of the drug. Mechanisms that account for mucositis are only partially known. This study assessed mechanisms and the role of inflammasome activation in irinotecan-induced mucositis. Mucositis in mice(More)
UNLABELLED Drug-induced liver injury (DILI) is an important cause of acute liver failure, with limited therapeutic options. During DILI, oncotic necrosis with concomitant release and recognition of intracellular content amplifies liver inflammation and injury. Among these molecules, self-DNA has been widely shown to trigger inflammatory and autoimmune(More)
OBJECTIVE The role of platelet-activating factor (PAF) on diet-induced inflammatory and metabolic dysfunction is unknown. The effects of diet-induced metabolic and inflammatory dysfunction in mice with deletion of the PAF receptor (PAFR(-/-) ) were evaluated in this study. METHODS Wild-type and PAFR(-/-) mice were fed chow (WT-C and PAFR(-/-) -C) or(More)
OBJECTIVE Evaluate the effect of fenofibrate treatment on the expression of PPARα and oxidative enzymes in adipose tissue. MATERIALS/METHODS Wistar male rats were fed a balanced diet supplemented with 100mg.Kg-1 bw.day-1 fenofibrate (Sigma) during nine days. Plasma glucose, free fatty acids (FFA) leptin and insulin were determined. PPARα, ACO and CPT-1(More)
Hepatic diseases are comorbidities caused by obesity and are influenced by diet composition. The aim of this study was to evaluate the kinetics of metabolic and inflammatory liver dysfunction induced by a high-refined carbohydrate-containing (HC) diet and to determine how platelet-activating factor (PAF) modulates the liver lipid content of mice. BALB/c(More)
The aim of the present study was to evaluate the potential of calcium supplementation from Lithothamnium muelleri algae on metabolic and inflammatory parameters in mice with increased adiposity. Male mice were fed and divided during 8 weeks in: control (C), a high refined carbohydrate-containing diet (HC), HC diet supplemented with 1% of Lithothamnion(More)
The postprandial state is a period of metabolic fluxes, biosynthesis and oxidative metabolism. A considerable amount is known about the inflammatory response to the chronic consumption of fructose, but little is known about its effects in the postprandial state. The aim of the present study was to investigate the inflammatory effects of a single meal(More)
BACKGROUND Mucositis is one of the most relevant gastrointestinal inflammatory conditions in humans, generated by the use of chemotherapy drugs, such as 5-fluoracil (5-FU). 5-FU-induced mucositis affects 80% of patients undergoing oncological treatment causing mucosal gut dysfunctions and great discomfort. As current therapy drugs presents limitations in(More)
The inflammation induced by obesogenic diets is associated with deposition of fat in the liver. On the other hand, anti-inflammatory and immunosuppressive therapies may impact in body fat storage and in liver lipid dynamics. It is important to study specific inflammatory mediators in this context, since their role on hepatic damage is not fully clarified.(More)
