t(11;14)(q13;q32) 是一种与某些慢性 B 细胞淋巴细胞恶性肿瘤相关的反复易位;假定的原癌基因 BCL1 位于染色体带 11q13,可能参与易位过程。为了确定 BCL1 重排是否与特定的淋巴瘤亚型相关,我们使用 BCL1 探针通过 Southern blot 分析对 131 个 B 细胞非霍奇金淋巴瘤样本进行了分析。在 25 例中间淋巴细胞淋巴瘤 (ILL) 病例中,有 9 例 (36%) 发生了 BCL1 位点重排;在 8 例弥漫性小裂细胞淋巴瘤病例中,有 1 例发生了 BCL1 基因座重排;在 12 例弥漫性混合细胞淋巴瘤病例中,有 1 例发生了 BCL1 基因座重排;在 21 例弥漫性大细胞淋巴瘤病例中,有 1 例发生了 BCL1 基因座重排。相比之下,在分析的 46 例滤泡性淋巴瘤中,从未发现 BCL1 发生重排。 BCL2 基因在所有 ILL 中均处于种系构型。 Southern 印迹与 JH、Cμ 和 BCL1 探针的顺序杂交仅在 ILL 病例中鉴定出共迁移片段,这表明在所有其他病例中,BCL1 的重排不是由 t(11;14) 易位引起的,或者 14 号染色体上的断裂发生在 JH 或 Cμ 区域之外。这些结果表明,BCL1 基因座的重排可能与 ILL 密切相关,并可被视为该淋巴瘤亚型的基因型标记。
The t(11;14)(q13;q32) is a recurring translocation associated with some chronic B‐cell lymphocytic malignancies; the putative protooncogene BCL1, located at the chromosome band 11q13, can be involved during the translocation process. In order to determine if BCL1 rearrangement is associated with a particular subtype of lymphoma, we analysed 131 B‐cell non‐Hodgkin's lymphoma samples by Southern blot analysis, using a BCL1 probe. The BCL1 locus was rearranged in 9 out of 25 (36%) cases of intermediate lymphocytic cell lymphomas (ILL), in 1 out of 8 cases of diffuse small cleaved cell lymphoma, in 1 out of 12 cases of diffuse mixed cell lymphoma, and in 1 out of 21 cases of diffuse large cell lymphoma. In contrast, BCL1 was never found rearranged in any of the 46 follicular lymphomas analysed. The BCL2 gene was in germ‐line configuration in all ILL. Sequential hybridization of Southern blots with JH, Cμ, and BCL1 probes identified comigrating fragments in only one case of ILL, which suggests that, in all the other cases, either the rearrangement of BCL1 did not result from a t(11;14) translocation or the break on chromosome 14 occurred outside the JH or Cμ regions. These results indicate that rearrangement of the BCL1 locus may be closely associated with ILL and could be considered as a genotypic marker of this lymphoma subtype.
