Figure 6: The methyltransferase inhibitor 5-Aza-dC reactivated both maspin and 14-3-3σ mRNA expression in chondrocytes and chondrosarcomas cell lines. The CS8E chondrosarcoma cell line and SNM83 normal chondrocyte cell line were exposed to 10 uM 5-Aza-dC. RNA was harvested after 48, 72, and 120 hours and subjected to RT-PCR for maspin and 14-3-3σ. GAPDH was used as loading control.
