Transcription profiling of effect of chronic ethanol consumption on Rattus norvegicus pancreas

ABSTRACT: Male Wistar rats weighing 90-120 g were acclimatized for one week and fed standard laboratory chow, at which time the animals were divided into two groups. Animals were then pair-fed for 8 weeks a regular laboratory chow and water âad libitumâ or Lieber-DeCarli diet (36% calories from ethanol). Control animals received the iso-caloric amount of dextrose to replace ethanol. After 8 weeks of differential feeding rats were euthanized, the pancreas immediately dissected and stored at -80?C until RNA isolation. RNA expression was analyzed using Affymetrix RAE230A gene chips Experiment Overall Design: pancreas from 3 rats feed control diets and 3 rats feed ethanol diets were analyzed

<h4>Objectives</h4>Long-term ethanol consumption does not cause acute pancreatitis but rather sensitizes the pancreas to subsequent insults. The mechanisms responsible for this sensitization are unknown. To determine whether alterations in pancreatic gene expression might participate in ethanol-mediated sensitization, we performed gene-profiling analysis.<h4>Methods</h4>Animals were fed ethanol-containing Lieber-DeCarli or control diet (pair-fed). After 8 weeks, pancreatic RNA expression was ana ...[more]

Alcohol Consumption Effects During the Inflammatory Stage of Fracture Healing in Rat Bones

Project description:Sprague-Dawley rats were placed on an ethanol-containing or pair-fed Lieber and DeCarli diets for 4 wks prior to surgical fracture. Following insertion of a medullary pin, a closed mid-diaphyseal fracture was induced using a Bonnarens and Einhorn fracture device. At 3 days post-fracture, the region of the fracture calluses were harvested from the right hind-limb. RNA was extracted and microarray analysis was conducted against the entire rat genome to study the effects of alcohol-consumption on the fracture healing. The experiments were on four rat subjects, i.e., pair-fed rats with subsequent surgical fracture or no surgical fracture, and alcohol-fed rats with subsequent surgical fracture or no surgical fracture. Each rat subject described above has three replicates so 6 kinds of pairing can be made and each pairing has a dye-swap replicate (thus, a total 12 array experiments). The focus of this study is on the pair-fed fracture subject vs. alcohol-fed fracture subject.

Exogenous miRNA expression profiling in serum of pig and rat fed with different diets

Project description:We performed carefully designed and controlled animal feeding studies. We devided 9 adult rats in three group and each group fed with one type of diets in 28 days: rice, potatoes and chow. We fed piglets in triplicate either with cow milk or let them feed from sows milk for 4 weeks followed by 7 weeks of maize diet. Based on the small RNA sequencing data from 9 rat and 6 pig serum samples, we detected no transfer of plant miRNAs into rat blood, or bovine milk sequences into piglet blood.

Dysregulation of miRNA regulatory networks by chronic ethanol consumption impairs liver regeneration

Project description:In this study, we elucidated the role of miRNA dysregulation in liver regeneration after partial hepatectomy (PHx) in chronic ethanol-treated rats. Male Sprague-Dawley rats were fed a liquid diet containing 36% of total calories derived from ethanol for 5 weeks; corresponding pair-fed calorie-matched controls were fed diets in which ethanol calories were replaced by carbohydrate. After 5 weeks, locked nucleic acid (LNA)-modified oligo antisense to miR-21 (AM21, Exiqon) was used to inhibit miRNA in vivo, and rats were subjected to 70% PHx. Liver samples were collected at 6 h, 24 h and 72 h after the surgery. The excised liver samples at t=0 served as within-animal controls.NanoString rat miRNA panel was used to obtain miRNA expression profile from 48 liver samples.

Transcription profiling of rat liver to investigate ethanol induced hepatic gene expression changes during gestation

Project description:The specific role of nutritional status during gestation in exacerbating or mitigating fetal toxicity of ethanol (EtOH) remains unclear. We used an intragastric infusion model (Total enteral nutrition, TEN) to appropriately control for dietary EtOH consumption and caloric intake. Time impregnated female Sprague Dawley rats (250-300 g) were surgically cannulated with intragastric cannulae (on gestation day 4) and infused either control or EtOH-containing diets. Rats were fed 220 kcal/ kg3/4/d (NRC recommended caloric intake for gestation) or 160 kcal/ kg3/4/d (undernourished to 72% of control) diets containing either 12 g/kg/d EtOH or an isocaloric amount of carbohydrates from gestation days 6-15. Maternal hepatic gene expression profiles were assessed on GD15. The present data dissect specific effects of nutritional status during gestation and EtOH intake and the interaction thereof. The data reveal a highly significant interaction between undernutrition and EtOH consumption. Experiment Overall Design: Four groups of time impregnated female Sprague Dawley rats were utilized. Experiment Overall Design: Group 1: Control, TEN-220, control group fed normal (non-EtOH containing) diets at 220 kcal/ kg3/4/d. Experiment Overall Design: Group 2: Ethanol-220, EtOH-220 (EtOH group fed EtOH containing diets) at 12 g EtOH/kg/d diets at 220 kcal/ kg3/4/d. Experiment Overall Design: Group 3: Control-160, TEN-160, (undernourished control group fed normal (non-EtOH containing) diets at 160 kcal/ kg3/4/d. Experiment Overall Design: Group 4: Ethanol-160, EtOH-160, (undernourished rats fed EtOH containing diets) at 12 g EtOH/kg/d diets at 160 kcal/ kg3/4/d

Gene expression in the chronic ethanol-treated rat liver during liver regeneration

Project description:In this study, we analyzed the effects of chronic alcohol consumption on liver repair and regeneration after partial hepatectomy (PHx). Rats were fed a liquid diet containing 36% of total calories derived from ethanol for 5 weeks; corresponding pair-fed calorie-matched controls were fed diets in which ethanol calories were replaced either by carbohydrate or by fat. After 5 weeks, rats were subjected to 70% PHx and liver samples were collected at 1, 6 and 24h after the surgery. The excised liver samples at t=0 served as within-animal controls. We used Affymetrix Rat Gene 1.0 ST arrays to obtain global gene expression data from each liver sample (n=4 replicate rats, 72 arrays total).

Multi-tissue, selective PPARγ modulation of insulin sensitivity and metabolic pathways in obese rats

Project description:We characterized the insulin sensitivity and multi-tissue gene expression profiles of lean and insulin resistant, obese Zucker rats untreated or treated with one of four PPARγ ligands (pioglitazone, rosiglitazone, troglitazone, and AG035029). We analyzed the transcriptional profiles of adipose tissue, skeletal muscle, and liver from the rats and determined whether ligand insulin-sensitizing potency was related to ligand-induced alteration of functional pathways. Ligand treatments improved insulin sensitivity in obese rats, albeit to varying degrees. Male Zucker fatty (fa/fa) and lean (fa/+) rats (Charles River, Wilmington, MA) were received at 6 weeks of age. Fatty rats were weight-matched upon arrival and randomly divided into one of five experimental groups. The fatty rat groups varied by the type of chow they were fed - normal chow alone or with a PPARγ ligand admixture: normal chow (fatty control, FC), rosiglitazone-treated (Rosi), pioglitazone-treated (Pio), troglitazone-treated (Tro), or AG035029-treated (AG). Lean control (LC) rats were all fed normal chow. Rats groups were maintained on the diets for 21 days.

Analysis of the role of miR-21 in liver regeneration after partial hepatectomy (PHx) in chronic ethanol-treated rats through in vivo inhibition using LNAs

Project description:In this study, we analyzed the role of miR-21 in liver regeneration after partial hepatectomy (PHx) in chronic ethanol-treated rats. Male Sprague-Dawley rats were fed a liquid diet containing 36% of total calories derived from ethanol for 5 weeks; corresponding pair-fed calorie-matched controls were fed diets in which ethanol calories were replaced by carbohydrate. After 5 weeks, locked nucleic acid (LNA)-modified oligo antisense to miR-21 (AM21, Exiqon, Vedbaek, Denmark) was used to inhibit miRNA in vivo, and rats were subjected to 70% PHx. Liver samples were collected at 24h after the surgery. The excised liver samples at t=0 served as within-animal controls. Rat Gene 2.0 ST (Affymetrix, Santa Clara, CA) arrays were used to obtain global gene expression data from pooled liver samples (pools of 3 or 4 biological replicates/array, total 8 arrays).
