Figure 4From: 125I seed irradiation induces up-regulation of the genes associated with apoptosis and cell cycle arrest and inhibits growth of gastric cancer xenograftsQuantitative RT-PCR validation for differential genes in microarrays. (A) Relative mRNA expression of 6 selected genes in microarrays (B) Validation of relative mRNA expression of selected genes with qRT-PCR. The significance of the varieties between the control group (solid bar) and 125I treatment group (hollow bar) was analyzed through student’s t-t test. (☆: P < 0.05).Back to article page
