Figure 1From: DNA methylation of the RIZ1 tumor suppressor gene plays an important role in the tumorigenesis of cervical cancer (a) RIZ1 mRNA in cervical cancer cell lines relative to normal tissues (n = 12). RIZ1 mRNA expression was absent in 2 of 4 cervical cancer cell lines. (b) RIZ1 mRNA expression in normal tissues(N) and match tumor tissues(T). RIZ1 mRNA expression in cervical cancer tissues was significantly lower than that in normal tissues(P < 0.05). (c) Reactivation of RIZ1 expression by inhibitor of DNA methylation in SiHa cells.Back to article page
