Table 1 The frequency of methylation of any BstUI site within a region, in oesophageal cell lines. The estimated frequency of methylation of any BstUI site within R1, R2 or R3, in the oesophageal cancer cell lines treated without (-) or with (+) with 1 μM aza-dC, where Δ is the change in methylation frequency. The results are from a single, representative experiment.
