骨髓增生异常综合征病人外周血细胞胆碱酯酶相关细胞分裂控制子基因表达

Expression of the Cholinesterase-Related Cell Division Controller Gene in Peripheral Blood Cell from Patients with Myelodysplastic Syndrome

为探讨胆碱酯酶相关细胞分裂控制子 (cholinesterase relatedcelldivisioncontroller ,CHED)基因在骨髓增生异常综合征 (MDS)病人中的表达情况 ,利用半定量RT PCR技术观察 2 1例MDS病人外周血细胞CHED基因的相对表达率。结果表明 :MDS病人的CHED基因相对表达率明显高于正常对照组 (P <0 .0 1) ;85 .7%MDS病人的CHED基因相对表达率高于正常对照组平均值 ,其中 3例随后转变为急性白血病 ;61.9%MDS病人的CHED基因相对表达率高于正常对照组高限 ;3例CHED基因相对表达率低于正常对照组平均值的病人没有发生急性白血病变。结论提示 。

To investigate the expression of the cholinesterase-related cell division controller(CHED) gene in the patients with myelodysplastic syndrome(MDS), CHED gene expression was assayed by RT-PCR and its relative expression rate(RER) was determined by the semi-quantitative RT-PCR analysis in peripheral blood mononuclear cells from 21 patients with MDS, 12 normal individuals served as controls. Results showed that RER of CHED in the patients(2.69±0.76) was significantly higher than that in controls(1.12±0.51, P< 0.01), the RER out of 85.7% of the patients was higher than the mean value of the controls, in which three patients developed into acute leukemia; the RER out of 61.9% of the patients was higher than the upper limit of the mean value of the controls; three patients whose RER was lower than the mean value of the controls did not developed into leukemia. These findings suggested that the expression of CHED gene in patients with MDS was significantly higher than in controls.
