Effects of 5 μM 5-aza-2'-deoxycytidine (Aza) on in vitro cultured primary parathyroid carcinoma cells (PC1). A, APC/GAPDH mRNA expression ratio as determined by real-time quantitative RT-PCR analysis. B, Western blotting analysis of APC. Coomassie blue-stained filter is shown as loading control. C, cell viability. D, apoptosis. Camptothecin at 0.1 μg/ml was used as positive control.
