Dysregulation of the WNT Signaling Pathway Through Methylation of Wnt Inhibitory Factor 1 and Dickkopf-1 Genes among AML Patients at the Time of Diagnosis
Background: In acute myeloblastic leukemia, a large number of tumor suppressor genes are silenced through DNA methylation such as CDKN2B & p73. Wnt inhibitory factor 1 (WIF1) and Dickkopf-3 (DKK-1) are negative regulators of Wnt signaling pathway. In the present study, we evaluated the methylation status of WIF1 and DKK-1 genes in acute myeloblastic leukemia patients. Patients and Methods: ...
متن کاملExpression and aberrant promoter methylation of Wnt inhibitory factor-1 in human astrocytomas
BACKGROUND Wnt inhibitory factor-1(WIF-1) acts as a Wnt-antagonists and tumor suppressor, but hypermethylation of WIF-1 gene promoter and low expression activate Wnt signaling aberrantly and induce the development of various human tumors. With this work we intended to investigate the expression and promoter methylation status of WIF-1 gene in human astrocytomas. METHODS The tissue samples con...

متن کاملGene Expression Status and Methylation Pattern in Promoter of P15INK4b and P16INK4a in Cord Blood CD34+ Stem Cells
Objective(s): Stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including P15INK4b and P16INK4a genes. Epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure. Materials and Methods: The CD34 + cord blood s...
