Exercise dependent gene regulation in cartilage

ABSTRACT: Objective. Exercise is crucial for maintaining cartilage integrity and providing prophylaxis against the onset of osteoarthritis (OA). Here we systematically examined the exercise driven transcriptional activation/repression of genes from healthy articular cartilage to dissect the metabolic pathways responsible for its potential benefits. Methods. Healthy Sprague-Dawley rats were either not exercised (control) or subjected to daily exercise (low intensity treadmill walking) for 2, 5, or 15 days. Subsequently, articular cartilage from distal femoral heads was harvested, RNA extracted and the transcriptome-wide regulation of gene expression analyzed by Affymetrix microarray chips. Kyoto Encyclopedia of Genes and Genome (KEGG) database was used to identify the metabolic pathways regulated by
