摘要
为了研究白血病患者体内是否有NUP98 HOXA、NUP98 HOXB、NUP98 HOXC、NUP98 HOXD融合基因 ,提取了骨髓中单个核细胞总RNA ,用甲醛变性电泳检测其完整性 ;反转录合成cDNA第一链并设计了 17对引物 ,以巢式PCR法 (nested PCR )扩增NUP98 HOXA融合基因 ;一步法扩增NUP98 HOXB、NUP98 HOXC和NUP98 HOXD融合基因 ,4 12bpGAPDH作为内参照引物 ,2 %琼脂糖凝胶电泳判断PCR结果。结果表明 :所提RNA完整 ,反转录后PCR扩增每个样本中均有内参照GAPDH的表达 ,但是未发现有NUP98 HOXA、NUP98 HOXB、NUP98 HOXC、NUP98 HOXD融合基因。结论 :在本研究所取新疆白血病人群中没有检测到NUP98 HOXA、NUP98 HOXB、NUP98 HOXC和NUP98 HOXD融合基因。
To investigate whether there are NUP98-HOXA,NUP98-HOXB,NUP98-HOXC,NUP98-HOXD fusion genes in leukemia patients in Xinjiang, cellular total RNA was extracted from the bone marrow mononuclear cells, the formaldehyde-agarose gel electrophoresis was used to judge whether RNA was intact, the 17 RT-PCR primers were designed to amplify the predicted fusion junctions and 412 bp GAPDH was used as an internal control, NUP98-HOXA fusion genes were amplified by nested-PCR following reverse transcription. One-step PCR was performed to amplify the other predicted fusion genes. The results showed that RNA was proved to be intact and expression of GAPDH was found in every sample. However, no predicted fusion transcripts were detected in leukemia patients. In conclusion, no NUP98-HOX fusion genes were detected in the samples from Xinjiang.
