We generated transgenic mice specifically targeting expression of mutant dominant negative human PPAR gamma (P467L) to vascular smooth muscle using a smooth muscle-specific promoter (smooth muscle myosin heavy chain or SMMHC). Thoracic aortas were isolated from male transgenic mice and corresponding non-transgenic littermate controls. Total RNA was prepared using conventional methods and quality was assessed using the Bioanalyzer 2100 (Agilent Technologies). For the microarray hybridizations, 2 samples from control mice and 3 samples from transgenic mice were used. Each sample was an independent biological replicate generated by pooling total RNA from 6-8 separate mouse aortas. All procedures were conducted at the University of Iowa DNA Core facility using standard Affymetrix protocols. In brief, approximately 3-5 ug of total RNA was used as input to a one-step amplification procedure to generate biotin-labeled RNA fragments for hybridization to the Affymetrix Mouse Genome 430 2.0 array.
