Abstract
AIM: Long noncoding RNAs serve critical regulatory functions highly specific for a tissue and its developmental stage. Antisense long ncRNA (AS-lncRNA) methylation changes in acute lymphoblastic leukemia (ALL) versus normal pre-B-cell lymphoblasts were evaluated to identify potential differential methylation in this group of genes. MATERIALS & METHODS: The methylome of ALL and normal lymphoblasts was examined by the methylated CpG island recovery assay followed by NGS. CONCLUSION: The potential effect of trans regulation by AS-lncRNA through DNA/RNA binding is significant as sequence alignment analysis of the 25 most differentially methylated AS-lncRNAs revealed 368 genes containing highly similar sequences with a median nucleotide identity of 90.8% and binding span of 122 base pairs. Regulation of biological processes and anatomical structure development were over represented. ALL classification schemes based on AS-lncRNA methylation can provide new insights into its pathogenesis and treatment.
