免疫球蛋白重链可变区 (VH) 基因在多发性骨髓瘤 (MM) 中的使用尚未有报道,尽管一些研究偶然发现了小群 MM 患者中 VH 基因的重排。我们使用基于逆转录酶-聚合酶链式反应的技术来分析 MM 中 VH 基因的使用。使用七个VH家族特异性引物和恒定区引物扩增骨髓cDNA后获得VH序列。成功鉴定了72名患者的VH序列。 VH家族使用频率按降序排列为VH3>VH4>VH1>VH5>VH2>VH6>VH7,并且对应于VH家族的功能种系复杂性。个别 VH 基因(VH1-69、VH3-9、VH3-23 和 VH3-30)在我们的 MM 患者队列中比例过高;一些 VH 基因 [VH3-49、VH3-53 和 VH4.21 (VH4-34)] 在正常循环 B 细胞、自身免疫性疾病和其他 B 细胞恶性肿瘤中重排频率增加,但在任何 MM 患者中均未检测到。与种系序列相比,每个 VH 序列内平均有 8.8%(范围为 2.7% 至 16.5%)的核苷酸有突变证据。基于这些结果,我们得出以下结论:(1) 与其他恶性和非恶性 B 细胞群相比,MM 中的 VH 基因使用是独特的,(2) 克隆删除功能的生理过程可去除具有重排 VH 基因 (VH4.21) 的克隆,这些克隆能够表达识别自身抗原的抗体,以及 (3) 完全缺乏 VH4.21 基因重排可能有助于部分解释 MM 中自身免疫现象的缺乏。 MM。
The immunoglobin heavy chain variable region (VH) gene usage in multiple myeloma (MM) has not been reported, although a few studies have incidentally identified the VH gene rearranged in small cohorts of MM patients. We used a reverse transcriptase-polymerase chain reaction based technique to analyze the VH gene usage in MM. The VH sequences were obtained after amplification of bone marrow cDNA using the seven VH family-specific and constant region primers. The VH sequences of 72 patients were successfully identified. The frequency of VH family usage in decreasing order was VH3>VH4>VH1>VH5>VH2>VH6>VH7 and corresponded to the functional germline complexity of the VH families. Individual VH genes (VH1-69, VH3-9, VH3-23, and VH3-30) were overrepresented in our cohort of MM patients; some VH genes [VH3-49, VH3-53, and VH4.21 (VH4-34)], which are rearranged with increased frequency in normal circulating B cells, autoimmune diseases, and other B-cell malignancies, were not detected in any MM patient. Compared with germline sequences, an average of 8.8% (range, 2.7% to 16.5%) of the nucleotides had evidence of mutation within each VH sequence. Based on these results, we conclude that (1) the VH gene usage in MM is unique compared with other malignant and nonmalignant B-cell populations, (2) the physiologic process of clonal deletion functions to remove clones that have rearranged VH genes (VH4.21) capable of expressing antibodies, which recognize self-antigens, and (3) the complete lack of VH4.21 gene rearrangement may help to partially explain the paucity of autoimmune phenomena in MM.
