Environmental conditions during the perinatal period influence metabolic and developmental processes in mammals and avian species, which could impact pre- and postnatal survival and development. The current study investigated the effect of eggshell temperature (EST) on glucose metabolism in broiler chicken embryos. Broiler eggs were incubated at a high (38.9°C) or normal (37.8°C) EST from day 1...
Impaired mitochondrial function has been implicated in the pathogenesis of type 2 diabetes, heart failure, and neurodegeneration as well as during aging. Studies with the PGC-1 transcriptional coactivators have demonstrated that these factors are central components of the regulatory network that controls mitochondrial function in mammalian cells. Here we describe a genome-wide coactivation assa...
To determine the effect of increased glycogen stores on hepatic carbohydrate metabolism, 15 nondiabetic volunteers were studied before and after 4 d of progressive overfeeding. Glucose production and gluconeogenesis were assessed with [2-3H] glucose and [6-14C] glucose (Study I, n = 6) or [3-3H] glucose and [U-14C]-alanine (Study II, n = 9) and substrate oxidation was determined by indirect cal...
The metabolic function of the liver changes sequentially during early life in mammals to adapt to the marked changes in nutritional environment. Accordingly, hepatic fatty acid β-oxidation is activated after birth to produce energy from breast milk lipids. However, how it is induced during the neonatal period is poorly understood. Here we show DNA demethylation and increased mRNA expression of ...
Mitochondria integrate metabolic networks for maintaining bioenergetic requirements. Deregulation of mitochondrial metabolic networks can lead to mitochondrial dysfunction, which is a common hallmark of many diseases. Reversible post-translational protein acetylation modifications are emerging as critical regulators of mitochondrial function and form a direct link between metabolism and protein...
BACKGROUND Two major risk factors for the onset of fatty liver disease are excessive alcohol intake and obesity, the latter being associated with non-alcoholic fatty liver disease (NAFLD). The aim of this study was to examine the effects of black rice extract (BRE) on hepatic steatosis and insulin resistance in high-fat diet-fed mice, providing a model of NAFLD. METHODS Twenty-four mice were ...
BACKGROUND Hepatic microvesicular steatosis is a clinical manifestation seen in a number of liver diseases. Although the role of mitochondrial beta-oxidation in the development of the disease has been well studied, information on lipid peroxidative damage in liver subcellular organelles is scarce. The present study looked at oxidative stress in hepatic peroxisomes and microsomes in microvesicul...
This study investigated the effect of tucum-do-cerrado consumption in the oxidative status of iron-supplemented rats. Four groups of rats were treated: Control (AIN-93G), Tuc (AIN-93G added of tucum-do-cerrado), Fe (AIN-93G iron-enriched), or TucFe (AIN-93G with tucum-do-cerrado and iron-enriched) diet, for 30 days. Iron-enriched diet increased serum, liver, spleen, and intestine iron levels; t...
Exercise training and regular physical activity increase oxidation of fat. Enhanced oxidation of fat is important for preventing lifestyle diseases such as hypertension and obesity. The aim of the present study in rats was to determine whether intake of dietary soya protein and exercise training have an additive effect on the activity and mRNA expression of enzymes involved in skeletal muscle f...
Mice fed diets containing trans 10, cis 12 (t10, c12)-conjugated linoleic acid (CLA) develop fatty livers and the role of the hepatic fatty acid oxidation enzymes in this development is not well defined. We examined the effects of dietary cis 9, trans 11-CLA (c9, t11-CLA) and t10, c12-CLA on the expression of hepatic genes for fatty acid metabolism. Female mice, 8 weeks old, (six animals per gr...
