CIAPIN1基因在白血病患者骨髓单个核细胞中表达的研究

本研究旨在检测CIAPIN1基因在白血病患者中的表达,探讨其在白血病中的作用。收集112例初治白血病患者的新鲜骨髓,用TRIzoL一步法提取细胞总RNA、合成cDNA、以β-actin为内参,应用实时定量PCR方法检测CIAPIN1mRNA的表达;实验中选择10例正常人的骨髓作为对照。结果表明:骨髓单个核细胞(MNC)中CIAPIN1mRNA在急性髓系白血病(AML)、急性淋巴细胞白血病(ALL)和慢性髓系白血病(CML)患者中的表达均高于正常人(p<0.05);在慢性淋巴细胞白血病(CLL)患者中的表达与正常人相比差异无统计学意义(p>0.05)。结论 :CIAPIN1基因在初治白血病患者MNC中表达升高,其表达上调在白血病的发病中可能有一定的作用。

Expression of CIAPIN1 gene in BMMNC of patients with leukemia

This study was aimed to investigate the expression level of C1APINI mRNA in leukemia patients and explore its significance in leukemias. The fresh bone marrow was collected from 112 newly diagnosed leukemia patients, the total RNA was extracted by means of TRIzoL, the eDNA was synthesized, the expression of CIAPIN1 mRNA was detected by real-time quantitative PCR using β-actin as internal reference; 10 normal healthy persons were selected as controls. The results showed that the expression of CIAPIN1 mRNA was statistically higher in acute myeloid leukemia （AML）, acute lymphocytic leukemia （ALL） and chronic phase chronic myeloid leukemia （CML） patients than that in normal persons （p 〈0.05）; but there was no statistical difference between chronic lymphocytic leukemia （CLL） and normal persons （p 〉 0.05 ）. It is concluded that the CIAPIN1 gene higher expresses in MNC of newly diagnosed leukemia patients, up-regulation of CIAPIN1 expression may play an important role in pathogenesis of leukemia.
