Epigenetic inactivation of the hsa-miR-203 in haematological malignancies.
Bottom Line: In CLL, hsa-miR-203 methylation was associated with a higher presenting Hb level (P = 0.033).In conclusion, miR-203, a tumour suppressor gene, was hypermethylated in a tumour-specific manner with gene silencing. hsa-miR-203 was more frequently hypermethylated in lymphoid than myeloid malignancies.In NHL, hsa-miR-203 methylation was associated with concomitant methylation of other tumour suppressor miRNAs.

Mentions: None of the eight normal control marrows showed aberrant methylation of hsa-miR-203 by MSP (Fig. 1A). The positive and negative controls showed the expected MSP results (normal DNA: U-MSP+/M-MSP–; methylated DNA: U-MSP–/M-MSP+).
