Death-associated protein kinase 1 (DAPK1), a proapoptotic serine/threonine kinase, is a candidate tumor suppressor gene. We studied the methylation status of the promoter region of the DAPK1 gene and the expression of the
DAPK1 protein
in 78 bone marrow samples from untreated patients with
myelodysplastic syndrome
(
MDS
) by PCR and Western blot analysis. Hypermethylation of DAPK1 was present in 42.3% (33 of 78) of
MDS
specimens and was significantly correlated with the loss of DAPK1 mRNA and protein expression (p < 0.01). There were no significant differences in methylation frequency among subgroup of
MDS
. DAPK1 hypermethylation in
MDS
was associated with the presence of cytogenetic abnormalities in the bone marrow at the time of the initial diagnosis. A higher frequency of DAPK1 hypermethylation was found in the unfavorable cytogenetic risk group (12 of 21 cases; 57.1%) compared to the favorable cytogenetic risk group (5 of 20 cases; 25.0%, p = 0.0368). These findings suggest that suppression of DAPK1 expression by DNA methylation may play a substantial role in the development of
MDS
