Figure 1 Methylation analysis of Igf2 DMR2 in normal and HCV related cirrhosis livers. A: Exon-intron structure of Igf2 gene. Exons are shown as numbered boxes (plain are coding). The 254bp fragment of Igf2 DMR2 amplified for methylation analysis is enlarged below. Vertical lines indicate CpG positions. B: DHLPLC chromatograms of PCR products from normal liver samples. Twenty-two out of 25 are superimposable, and this major profile was used to assess hypermethylated profiles (ie more methylated than normal liver). C and D: DHPLC chromatograms of PCR products from HCV-related cirrhosis. Among 94 samples, 13 (C) and 17 (D) samples show respectively hypomethylated and hypermethylated profiles.
