Methylation Status of SOCS1 and SOCS3 Genes in Patients with Acute Lymphoid Leukemia
Abstract
Background: Acute Lymphoid Leukemia (ALL) is the leading childhood cancer with a high mortality and
morbidity. Studies have suggested an association of epigenetic transformations with prognosis, recurrence
and immunophenotypes of ALL. SOCS1 and SOCS3 are tumor suppressors inhibiting JAK/STAT signaling
pathway and the resultant aberrant cell proliferation.
Method: We aimed to assess the association between methylation status and ALL, using bone marrow and
peripheral blood samples. 18 patients with ALL and 13 children with no malignancies were included. Using
Bisulfite conversion, quantitative multiplex methylation-specific PCR and 2 -∆∆Ct formula, the methylated
DNA in the promoters of SOCS1 and SOCS3 were measured.
Results: ALL patients had higher mean methylation in SOCS1 promoter and lower mean methylation in
SOCS3 promoter, compared to the control group. However, neither of these mean differences were statistically
significant.
Conclusion: This finding can set the foundation for further large-sample studies with the use of healthy
children as a control group to strengthen the hypothetical association of the methylation status of SOCS1
and SOCS3 with ALL.
