Table 2 The frequency of methylation of any BstUI site within R1, in oesophageal cell lines. The estimated frequency of methylation at each BstUI site of R1 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.
