Figure 5From: Arsenic trioxide inhibits the proliferation of myeloma cell line through notch signaling pathwayATO regulated the level of PTEN mRNA expression in RPMI8226. Myeloma cell were treated with different concentrations ATO (0, 0.5, 5 and 10 μM) for 48 hours, PCR results showed that PTEN mRNA expression was increased in RPMI8226 cell.Back to article page
