Real-time PCR data are shown as fold change (±SEM) relative to mean Sham values. In TAC mice, propranolol treatment caused a significant increase of cell cycle gene expression including both genes associated with cell proliferation and those known to negatively regulate cell cycle progression. For each group, individual data points expressed as 2−ΔCt[2 −(Ctgene target−Ctgapdh)] were used for statistical analysis (Schmittgen and Livak, 2008).
