Publication Status journal_article Publication Status Term Source REF The MGED Ontology Experiment Description Endurance training accelerated development of right ventricular dysfunction and arrhythmias in plakoglobin+/- mice. Histology and electron microscopy did not identify right ventricular abnormalities. To identify differences in the transcriptional response to training gene expression profiling was performed. Experiment Overall Design: Gene expressson analyses were performed in 5 pairs of plakoglobin (+/-) mice and their wildtype littermates. Four pairs of trained mice and one pair of old untrained mice were studied. Training induced expression of several hypertrophy associated genes such as ANP but no differences between the trained plakoglobin (+/-) mice and wt mice was seen.

Swimming duration was continously increased from 5 minutes to 90 minutes daily (6 times per week) swimming. Mice were stimulated to swim as sonn as they began floating to maximize activity in the water. untrained TRIzol Reagent (Invitrogen), standard protocol The amplification and labeling of the RNA samples were carried out according to the manufacturer's instructions (Affymetrix, Santa Clara, CA). Briefly, total RNA was quantified by UV-spectroscopy and its quality was checked by analysis on a LabChip (BioAnalyzer, AGILENT Technologies, Santa Clara, CA). In the presence of an oligo(dT)24 primer containing a T7 RNA polymerase promoter (TIBMOL Biol, Berlin, Germany) one to three micrograms of total RNA were used for the synthesis of double-stranded cDNA (SuperScript transcriptase, Life Technologies, Inc., Carlsbad, CA). Labeled complementary RNA (cRNA) was prepared from double-stranded cDNA by in vitro transcription using the GeneChip RNA transcript labeling kit (Affymetrix, Santa Clara, CA). After cleanup (Qiagen, Hilden, Germany), the biotin-labeled cRNA was fragmented by alkaline treatment [40 mmol/L Tris-acetate (pH 8.2), 100 mmol//L potassium acetate, and 50 mmol//L magnesium acetate] at 94°C for 35 minutes. 15 ug of each cRNA sample was hybridized for 16 hours at 45°C to rat expression Affymetrix RAE 230A GeneChip arrays. Following the hybridization arrays were washed and stained with streptavidin-phycoerythrin using a fluidics station in accordance with the Affymetrix protocol.
