Project description:Large White and Meishan pigs were either non-treated or injected with mammalian 1-24 ACTH (Immediate Synachten, Novartis France) at the dose of 250 µg per animal. Pigs were sacrificed either immediately after capture from their home cage (non-treated animals) or 1 hour following ACTH injection. Adrenal glands were immediately collected from pigs and frozen on dry ice and then stored at -80°C until RNA isolation. Keywords: stress response, adrenal, gene expression, pig

Project description:Clenbuterol-HCL can greatly reduce fat deposition and increase skeletal muscle growth at high dosages. In order to advance our understanding of the fundamental molecular mechanisms, Genechips were used to study the differential gene expression profiles of liver tissues among the pigs with/without Clenbuterol-HCL. Differentially expressed genes identified will be the candidates for further investigations on the molecular mechanisms involved in Clenbuterol-HCL of exerting repartition effects on adipose and skeletal muscle tissue. 4 Chinese mininature pigs were broken into 2 groups with each group having two full sib pigs with the same gender. For the following 8 weeks, test pigs were fed 25 mg/kg clenbuterol twice daily in their diets for 4 weeks and 50 mg/kg clenbuterol for another 4 weeks. The vehicle control pigs were administered in the same manner except that no clenbuterol was added in their diets. The liver expression profiles of 4 pigs were analyzed using Porcine Genome GeneChip. After hybridization, genechips were washed and stained in the Affymetrix Fluidics Station 400 and scanned by using Hewlett-Packard GeneArray Scanner G2500A.
Project description:To optimize the genome annotation, nine tissue and one pool RNA libraries (i.e. heart, liver, spleen, lung, kidney, muscle, fat, ovary, pool.) were constructed using the Illumina mRNA-spleeneq Prep Kit
