Figure 5From: Human mammary cancer progression model recapitulates methylation events associated with breast premalignancyDNA methylation correlates with reduced gene expression. Quantitative RT-PCR for (a) RASSF1A; (b) SFRP1; and (c) MGMT. Methylation status as evaluated by MSP is indicated as follows: Unmethylated (U), partially methylated (U/M), or methylated (M). For SFRP1, the U/M labels refer to the methylation status of the CpG island that extends into exon 1.Back to article page
