Abstract:
OBJECTIVE:To analyze the polymorphisms of glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) gene exon 14, GPI-PLD activity of leucocyte in the peripheral blood,and the relationship in leukemia patients of Han nationality in Hunan.
METHODS:Both 96 leukemia patients and 96 healthy persons of Han nationality in Hunan were researched [including 48 acute non-lymphocytic leukaemia (ANLL) patients as group A, 31 acute lymphoblastic leukaemia (ALL) patients as group B, 12 chronic granulocytic leukaemia (CML) patients as group C, 5 chronic lymphocytic leukaemia (CLL) patients as group D]. The polymorphisms were analyzed by PCR-SSCP and sequencing;. and GPI-PLD activities were determined by GPI-anchored placental alkaline phosphatase (PLAP) as substrate and triton-X114 partioning.
RESULTS:There were four variations in the coverage of GPI-PLD gene exon 14 of leukemia patients and healthy persons. The codons of variation were: 1257 C-->T, 1298 T-->C, 1218 C-->A, 1257 C-->A. The total various frequency in leukemia patient and healthy person, which was determined by SSCP, was 28.12% and 20.83%. On the basis of the percentage of GPI-anchored PLAP conversion, the leucocyte GPI-PLD activities of the 96 leukemia patients were measured. Compared with the 96 healthy controls, the leukocyte GPI-PLD activites of ANLL and CLL patients were significantly increased; the acticities of ALL and CML patients were significantly reduced.
CONCLUSION:Leukocyte GPI-PLD gene in the peripheral blood, which belongs to healthy persons and leukemia patients of Han nationality in Hunan, is polymorphism. The leukocyte GPI-PLD activities in the four groups are remarkable.
