Analysis of PPARalpha deficient small intestines after a 24 hour fast. PPARalpha is a fatty acid-activated transcription factor. Results provide insight into transport function and phase I/II metabolism in the small intestine during fasting and the role of PPARalpha in the response to fasting.

(Submitter supplied) Background: The selective absorption of nutrients and other food constituents in the small intestine is mediated by a group of transport proteins and metabolic enzymes, often collectively called ‘intestinal barrier proteins’. An important receptor that mediates the effects of dietary lipids on gene expression is the peroxisome proliferator-activated receptor alpha (PPARα), which is abundantly expressed in enterocytes. more...

(Submitter supplied) Obesity and insulin resistance are two major risk factors underlying the metabolic syndrome. To gain more insight in the role of the small intestine in the etiology of these metabolic disorders, a microarray study was performed on small intestines (SI) of C57BL/6J mice that were fed a high fat diet mimicking the fatty acid composition of a Western-style human diet. The mice became obese and developed dietary fat-induced glucose intolerance. more...

Analysis of small intestines of male C57BL/6J rodents fed a powdered high-fat purified diet for up to 8 weeks. Diet contributes to obesity and insulin resistance (IR) development. Results provide insight into the molecular mechanisms underlying dietary fat-induced obesity and IR pathogenesis.

(Submitter supplied) 8 week-old male Hsd:ICR(CD-1) mice were fed ad libitum a standard chow (Harlan Teklad diet 2018S) and housed in groups of five. Animals were then divided into 3 pools (n=10) and sacrificed. The small intestine was extracted and divided into three sections, where the first 2-3 cm after the stomach comprised the duodenum, the middle third the jejunum, and the section before the ileo-ceco-colic junction comprised the ileum. more...

(Submitter supplied) The peroxisome proliferator-activated receptor alpha (PPARα) is a fatty acid-activated transcription factor that governs a variety of biological processes. Little is known about the role of PPARα in the small intestine. Since this organ is frequently exposed to high levels of PPARα ligands via the diet, we set out to characterize the function of PPARα in small intestine using functional genomics experiments and bioinformatics tools. more...

(Submitter supplied) Knowing the gene expression profiles of drug-metabolizing enzymes and transporters throughout gestation is important for understanding the mechanisms of pregnancy-induced changes in drug pharmacokinetics. In this study, we compared gene expression of drug-metabolizing enzymes and transporters in the maternal liver, kidney, small intestine, and placenta of pregnant mice throughout gestation by microarray analysis. more...

(Submitter supplied) Background: Studies in mice have shown that PPARα is an important regulator of lipid metabolism in liver and a key transcription factor involved in the adaptive response to fasting. However, much less is known about the role of PPARα in human liver. Here we set out to study the function of PPARα in human liver via analysis of whole genome gene regulation in human liver slices treated with the PPARα agonist Wy14643. more...

(Submitter supplied) Studies in mice have shown that PPARα is an important regulator of hepatic lipid metabolism and the acute phase response. However, little information is available on the role of PPARα in human liver. Here we set out to compare the function of PPARα in mouse and human hepatocytes via analysis of target gene regulation. Primary hepatocytes from 6 human and 6 mouse donors were treated with PPARα agonist Wy14643 and gene expression profiling was performed using Affymetrix GeneChips followed by a systems biology analysis. more...

(Submitter supplied) Background The gut is a major energy consumer, but a comprehensive overview of the adaptive response to fasting is lacking. Gene-expression profiling, pathway analysis, and immunohistochemistry were therefore carried out on mouse small intestine after 0, 12, 24, and 72 hours of fasting. Results Intestinal weight declined to 50% of control, but this loss of tissue mass was distributed proportionally among the gut’s structural components, so that the microarrays’ tissue base remained unaffected. more...
