Effect of nandrolone on cell cycle. (A) Cell cycle analysis of HepG2 nandrolone treated cells (ND) using ModFit software (Verity Software House). Histogram plots were shown on the right. Data, expressed as percentage of total events analyzed, are the means ± SD of three independent experiments; **P < 0.01; ***P < 0.005. PI: propidium iodide. (B) Protein expression levels of key regulators of cell cycle progression, Cyclin D1, Cyclin E, Cdk1/2, p21 and p53, assayed by Western blotting in untreated and 80 μM nandrolone-treated cells for 72 h. Upper panel: a representative cropped immunoblot. Full-length blots are presented in Supplementary Fig. S1. Bottom bar histogram: densitometry analysis normalized to β-actin as means ± SEM of three independent experiment; **P < 0.01; ***P < 0.001. A.U.: arbitrary unit.
