title: [Application of Bisulfite Sequencing PCR in Detecting the Abnormal Methylation of Suppressor Gene of Wnt Signaling Pathway in Acute Promyelocytic Leukemia].
abstract: OBJECTIVE
  To detect the abnormal methylation of the CPG island in the suppressor gene promoter region of the Wnt signaling pathway in cell strain NB4 of the acute promyelocytic leukemia by using the bisulfite sequcucing PCR(BSP), to screan the hyper-methylated suppressor gene of the Wnt signaling pathway and to evaluatc the potency of BSP in the methylation study.
  
  
  METHODS
  The strain NB4 cells of the acute promyelocytic leukemia patients were used as the object, the mononuclear cells from 20 normal persons were used as the controls. The DNA was extracted and processed by bisulfite, the target sequences were amplified with PCR, then the abnormal methylation of the suppressor genes of the Wnt signaling pathway in the NB4 cells was analyzed by BSP, and the advantage and disadvantage of BSP were evaluated by comparison with the Methylation specific PCR and Pyrosequencing.
  
  
  RESULTS
  The methylated rate of suppressor genes of the Wnt signaling pathways in the NB4 cells detected by BSP was as follows: the gene WIF1 95.26%, the gene DKK3 86%, the gene SFRP1 81.67%, the gene SFRP2 95.71%, the gene SFRP4 85%, and the gene SFRP5 95%; while the methylations in the control group were respectively as follows: the gene WIF-1 1.5%, the gene DKK3 4.2%, the gene SFRP1 0%, the gene SFRP2 0.9%, the gene SFRP4 2.5%, and the gene SFRP5 1.75%. A more significant methylation happened in the suppressor genes promoter of the Wnt signaling pathway in the NB4 cells as compared with the control group.
  
  
  CONCLUSIONS
  Many hypermethylated suppressor genes are found in the Wnt signaling pathway of the acute promyelocytic leukemia NB4 cells, which may be served as one of the early diagnosis index and therapeutic target of the acute promyelocytic leukemia.
