据报道,基因内外显子重排(IERs)的表达在正常细胞和癌细胞中都被检测到。然而,这些重排发生特异性肿瘤,包括恶性淋巴瘤的报道很少。在本研究中,我们利用高分辨率单核苷酸多态性阵列检测了非霍奇金B细胞淋巴瘤(B- nhl)细胞系kpuma - uh1中10个基因(NBPF8、SOBP、AUTS2、RAB21、SPATA13、ABCC4、WDR7、PHLPP1、nfatc1和maged1)的IERs,并利用逆转录聚合酶链反应在基因组基因内获益的外显子内进行测序分析。其中,涉及sobp (6q21)外显子2和3和auts2 (7q11.22)外显子2 - 4的ier是肿瘤特异性的分子病变,在B-NHL样本中经常检测到。这些ier构成了B-NHL的新的遗传改变,可能与肿瘤发生有关,并可作为遗传生物学标记。
Expression of intragenic exon rearrangements (IERs) has reportedly been detected in both normal and cancer cells. However, there have been few reports of occurrence of these rearrangements specific to neoplasms including malignant lymphoma. In this study, we detected IERs of ten genes (NBPF8,SOBP,AUTS2,RAB21,SPATA13,ABCC4,WDR7,PHLPP1,NFATC1andMAGED1) in non-Hodgkin B cell lymphoma (B-NHL) cell line KPUM-UH1 using a high-resolution single nucleotide polymorphism array and reverse transcription polymerase chain reaction using reversely directed divergent primers within exons involved in genomic intragenic gains followed by sequencing analysis. Among them, the IERs involved inSOBP(6q21) exon 2 and 3 andAUTS2(7q11.22) exon 2–4 were the molecular lesions specific to tumors and were frequently detected in B-NHL samples. These IERs constitute novel genetic alterations of B-NHL, which might be associated with tumorigenesis and be useful as genetic biological markers.
