Effects of Dietary Vitamin B6 Restriction on Hepatic Gene Expression Profile of Non-Obese and Obese Mice.

Although vitamin B6 is contained in various foods, its deficiency is one of the most common micronutrient deficiencies worldwide. Furthermore, patients with obesity and cardiovascular disease are more likely to have suboptimal vitamin B6 status than healthy people. Therefore, we investigated the effects of dietary vitamin B6 restriction on hepatic gene expression and function in obese mice.

Maternal Consumption of a Low-Isoflavone Soy Protein Isolate Diet Accelerates Chemically Induced Hepatic Carcinogenesis in Male Rat Offspring.

It has been reported that maternal nutrition determines the offspring's susceptibility to chronic diseases including cancer. Here, we investigated the effects of maternal diets differing in protein source on diethylnitrosamine (DEN)-induced hepatocarcinogenesis in adult rat offspring. Dams were fed a casein (CAS) diet or a low-isoflavone soy protein isolate (SPI) diet for two weeks before mating and throughout pregnancy and lactation.

Maternal Consumption of Low-Isoflavone Soy Protein Isolate Confers the Increased Predisposition to Alcoholic Liver Injury in Adult Rat Offspring.

Offspring of female rats fed either a casein (CAS) diet or a low-isoflavone soy protein isolate (SPI) diet were compared in an animal model of chronic ethanol consumption to investigate whether maternal diet regulates the adaptive responses of offspring to postnatal ethanol exposure and potentially affects the development of liver disease in later life. Female rats were fed either a CAS or an SPI diet before mating, and during pregnancy and lactation. Male offspring from the same litter were pair-fed either a control or ethanol diet for six weeks (CAS/CON, CAS/EtOH, SPI/CON, and SPI/EtOH groups).

Different Effects of Maternal Low-Isoflavone Soy Protein and Genistein Consumption on Hepatic Lipid Metabolism of 21-Day-Old Male Rat Offspring.

Amino acid composition and isoflavone are alleged contributors to the beneficial effects of soy protein isolate (SPI) on lipid metabolism. Therefore, we investigated the contributing component(s) of SPI in a maternal diet to the regulation of lipid metabolism in offspring. We also determined serum parameters in dams to investigate specific maternal cues that might be responsible for this regulation.

Altered lipid metabolism in rat offspring of dams fed a low-protein diet containing soy protein isolate.

Aims: Substantial studies have reported that maternal protein restriction may induce later development of cardiovascular disease in offspring by impairing antioxidant system and lipid metabolism. Because a unique amino acid composition of soy protein isolate has been shown to provide health benefits, including hypolipidemic effects, we investigated effects of maternal low-protein diet composed of low-isoflavone soy protein isolate (SPI) on oxidative stress and lipid metabolism in offspring.

Main Methods: Sprague-Dawley dams were fed 20% or 10% SPI diet throughout pregnancy and lactation.

Maternal consumption of low-isoflavone soy protein isolate alters hepatic gene expression and liver development in rat offspring.

In utero environment is known to affect fetal development. Especially, the distinct fetal programming of carcinogenesis was reported in offspring exposed to maternal diets containing soy protein isolate (SPI) or genistein. Therefore, we investigated whether maternal consumption of low-isoflavone SPI or genistein alters hepatic gene expression and liver development in rat offspring.

Inhibitory effects of Doenjang, Korean traditional fermented soybean paste, on oxidative stress and inflammation in adipose tissue of mice fed a high-fat diet.

Background/objectives: Doenjang, Korean traditional fermented soybean paste has been reported to have an anti-obesity effect. Because adipose tissue is considered a major source of inflammatory signals, we investigated the protective effects of Doenjang and steamed soybean on oxidative stress and inflammation in adipose tissue of diet-induced obese mice.

Materials/methods: Male C57BL/6J mice were fed a low fat diet (LF), a high-fat diet (HF), or a high-fat containing Doenjang diet (DJ) or a high-fat containing steamed soybean diet (SS) for 11 weeks.

Dietary Supplementation of Genistein Alleviates Liver Inflammation and Fibrosis Mediated by a Methionine-Choline-Deficient Diet in db/db Mice.

Nonalcoholic fatty liver disease is a complex disorder which includes simple steatosis, steatohepatitis, fibrosis and ultimately cirrhosis. Previous studies have reported that genistein, a soy phytoestrogen, attenuates steatohepatitis induced in obese and type 2 diabetic models. Here we investigated the effect of dietary genistein supplementation (0.

Betaine Alleviates Hypertriglycemia and Tau Hyperphosphorylation in db/db Mice.

Betaine supplementation has been shown to alleviate altered glucose and lipid metabolism in mice fed a high-fat diet or a high-sucrose diet. We investigated the beneficial effects of betaine in diabetic db/db mice. Alleviation of endoplasmic reticulum (ER) and oxidative stress was also examined in the livers and brains of db/db mice fed a betaine-supplemented diet.

Protective effect of Pinus koraiensis needle water extract against oxidative stress in HepG2 cells and obese mice.

Needles of pine species are rich in polyphenols, which may exert beneficial effects on human health. The present study was conducted to evaluate the in vitro and in vivo antioxidant effects of Pinus koraiensis needle water extracts (PKW). HepG2 cells were pretreated with various concentrations of PKW (from 10(-3) to 1 mg/mL) and oxidative stress was induced by tert-butyl hydroperoxide (t-BOOH).
