Subject with Duchenne Muscular Dystrophy, prior to treatment. Messenger RNA isolated from a gastrocnemius muscle needle biopsy was linearly amplified (two rounds) and biotin-labeled using the protocol of Baugh, et al (Baugh, L. R., Hill, A. A., Brown, E. L., and Hunter, C. P. Quantitative analysis of mRNA amplification by in vitro transcription. Nucleic Acids Res 29(5), E29. 2001). Labeled RNA was hybridized to array using Affymetrix' protocol. Keywords = muscle Keywords = Duchenne muscular dystrophy Keywords = oxandrolone Keywords = androgen
