Inflammatory bowel disease (IBD) is a multifaceted and recurrent immune disorder that occurs in the gastrointestinal tract. Betaine is a natural compound that exerts beneficial anti-inflammatory effects. However, the role of betaine in protecting IBD is still unclear.

We have observed that BLF and main effective components morin and quercetin 3-O-rhamnoside pretreatment significantly inhibited LPS-stimulated inflammatory activation of RAW264.

Hepatoprotective effects of a purified polysaccharide (TOP-2) were evaluated by alcohol-induced liver injury model mice. The optimal UMAE parameters were indicated as below: ratio of water to raw material 28 mL/g, microwave power 114 W, extraction time 11 min.

Previous studies have indicated that HFD could disturb the immune system, leading to immunodeficiency and inflammation. Several mechanisms have been postulated to account for immunodeficiency associated with HFD, one being oxidative stress.
View Article and Find Full Text PDFObjective: This study investigated whether spleen oxidative stress induced by a high-fat diet (HFD) influences the expression of genes involved in B-cell activation, thus leading to B-cell-related immunosuppression.
Methods: Male C57BL/6 mice were randomly assigned to one of three groups with eight mice in each group. The control group consumed an ordinary diet (4.
Antioxidant lipoic acid (LA) has been reported to have a potential prophylactic effect on bone loss induced by high-fat diet (HFD). The aim of this work was to examine the hypothesis that LA decreases bone resorption-related gene expression and increases bone formation-related gene expression in HFD-fed mice, preventing a shift in the bone metabolism balance toward resorption. Male C57BL/6 mice were fed a normal diet, HFD, or HFD plus 0.

Methods: Male C57BL/6 mice were randomly assigned to one of four groups with eight mice in each group. The control group consumed an ordinary diet (4.
Objective: The present study examined impacts of dyslipidemic high-fat diet on the bone antioxidant system and bone metabolism in growing mice. Furthermore, the relationship was studied between them.
Methods: Male C57BL/6 mice (4 wk old) were fed with normal diet, high-fat diet (HFD), or HFD supplemented with 0.
Somatostatin plays an important role in glucose homeostasis. It is normally secreted in response to glucose and ATP generation is believed to be the key transduction signal of glucose-stimulated somatostatin secretion (GSSS). However, in the present study, in cultured rat gastric primary D-cells, GSSS was accompanied by increases in cellular reactive oxygen species (ROS).

The present study investigated the possible molecular mechanisms for the dyslipidemic HFD-induced bone loss through comparing femoral gene expression profiles in HFD-fed mice versus the normal diet-fed mice during the growth stage. We used Affymetrix 430A Gene Chips to identify the significant changes in expression of the genes involved in bone metabolism, lipid metabolism, and the related signal transduction pathways.
View Article and Find Full Text PDFOxidative stress plays an important role in overnutrition-induced metabolic syndrome. Somatostatin (SST) inhibits a wide variety of physiologic functions in the gastrointestinal tract, which may in turn control the levels of reactive oxygen species (ROS) derived from ingestion of macronutrients. In this study, the involvement of SST in the progression of metabolic syndrome in response to a high-fat diet (HFD) was investigated.
View Article and Find Full Text PDFA high fat diet (HFD) has long been linked to immune dysfunction, including diminished numbers or reactivity of lymphocytes, increased susceptibility to infection, inhibited lymphocytes function during antigen-specific responses and developed oxidative stress. Whereas the molecular mechanistic events associated with immune deficiency remain to be fully determined. Using the DNA microarray system, we analyzed the gene expression patterns of lymphocyte related signal transduction proteins in jejunum of C57BL/6 mice in order to gain insight on the possible molecular mechanism by which HFD induced oxidative stress effects on signal transduction of lymphocytes.
