Table 4: Statistical analysis of the results obtained by methylation assay performed on μ-protocadherin promoter region. The mean percentage of methylated CpG nucleotides, detected in all sample groups, were subjected to the paired Tukey HSD Test. This evaluation was carried out separately for CpG1 and CpG2 sequences, respectively presented in the upper and lower lane of each table row. CRC MUPCDH+ and -, CRC positive and negative for μ-protocadherin expression respectively.
