From: In Vitro Effects of Beta-2 Agonists on Skeletal Muscle Differentiation, Hypertrophy, and Atrophy
Dose-dependent effect of clenbuterol on mRNA expression of atrophic genes. Atrophic genes mRNA expression of atrogin-1 (A), MuRF1 (B), and cathepsin L (C) by qPCR in terminally differentiated myotubes grown in presence of 10-4 M, 10-5 M, 10-6 M, 10-7 M, or 10-8 M clenbuterol or in presence of vehicle alone. Bars represent mean ± SD of 3 different independent experiments; statistical significance was analyzed between beta-2 agonists treated versus untreated cells. **P < 0.001.
