摘    要:在Southern印迹法分析的基础上用PCR方法分析了27例小儿急性白血病细胞的免疫球蛋白重链基因VDJ区的变化。6例未分化型白血病中5例有V_H-D_H-J_H基因扩增带,提示已定向B系。13例B系来源的白血病细胞中9例发生VDJ完全重排,4例B系来源和1例未分化型白血病PCR无阳性扩增带而Southern印迹法有重排带。1例普通型白血病PCR有阳性扩增带而Southern印迹法呈胚系。在14例阳性病例中有1例出现二条扩增带呈双克隆性。1例T细胞性白血病和7例非淋系白血病均为阴性与southern印迹法结果一致,对2例未分化型,2例普遍型白血病进行顺序分析,发现它们的重排格局各不相同。

关 键 词:免疫球蛋白重链基因VDJ区,小儿急性白血病,聚合酶链反应,基因重组和序列

Abstract:ased on Southern Blot ailalysis we investigated the structure of the V_H DJ_H joining regionin 27 childhood acute leukemia patients by polymerase chain reaction(PCR). The result showed:(1)The amplified bands were found in five of 6 acute undifferentiated leukemia,(2) Nine of 13B-ALL had VDJ rearrangement,the rest 4 cases were negitive in PCR but.positive in SouthernBlot.(3)One case was positive in PCR but negitive in Southern Blot.(4)Two amplified bandwere found in one of 14 positive cases of PCR, which,suggested that this might be biclonality.(5)Seven of no lymphocytic leukemia and one of T-ALL showed negitive agreed with the re-sults of Southern Blot. (6)The sequences were analyzed in the leukemic DNA from 2 of acuteundifferentiated leukemia and 2 of prepre-B acute leukemia. The data indicated that they mighthave different rearrangement patterns.
Keywords:Immunoglobulin heavy chain geneVDJ region Childhood acute leukemia PCR Gene rearrangements and.sequences
