| Popis: | We examined the methylation status of the third exon of the MYC oncogene in 39 patients with B-cell malignancies. DNA was digested with MspI plus EcoRI or HpaII plus EcoRI and hybridised with a probe specific for the third exon of MYC. Thirty four patients showed complete methylation of the CCGG site. Four patients, one with chronic B-cell leukaemia and one with pro-lymphocytic leukaemia (PLL) and two with B-cell lymphoma showed partial hypomethylation of the CCGG site, while another patient with PLL showed complete hypomethylation of the CCGG site. These results suggest that hypomethylation of the MYC oncogene is infrequent in B-cell tumours but may be involved in the development of some cases of B-cell malignancies. |
