Global DNA methylation and hydroxymethylation according to cytogenetic risk groups a 5-methylcytosine (5-mCyt) and b 5-hydroxymethylcytosine (5-hmCyt) were determined by ELISA in purified B cells from 15 healthy controls and 60 untreated chronic lymphocytic leukemia (CLL) patients classified according to their cytogenetic risk group. ELISA results are expressed as indexes using a DNA reference sample for normalization (see “Materials and methods” section). The means and statistical differences were indicated when Dunn’s correction test was statistically significant (p < 0.05)
