We surveyed lymphomas to determine the range of expression of the mantle cell lymphoma-associated SOX11 transcription factor and its relation to cyclin D1.
On hundred and seventy-two specimens were immunostained for the SOX11 N and C termini. Cyclin D1 was detected by immunohistochemistry and quantitative reverse transcriptase polymerase chain reaction; in situ hybridization for t(11;14) was applied when needed.
Nuclear SOX11 was strongly expressed in most B and T-lymphoblastic leukemia/lymphomas and half of childhood Burkitt's lymphomas, but only weakly expressed in some hairy cell leukemias. Chronic lymphocytic leukemia/lymphoma, marginal zone, follicular and diffuse large B-cell lymphomas were negative for SOX11, as were all cases of intermediate Burkitt's lymphomas/diffuse large B-cell lymphoma, myeloma, Hodgkin's lymphomas and mature T-cell and NK/T-cell lymphomas.
In addition to mantle cell lymphoma, SOX11 is strongly expressed only in lymphoblastic malignancies and Burkitt's lymphomas. Its expression is independent of cyclin D1 (except for weak expression in hairy cell leukemias) and unlikely to be due to translocations in lymphoid neoplasia.
我们调查了淋巴瘤,以确定套细胞淋巴瘤相关的 SOX11 转录因子的表达范围及其与 cyclin D1 的关系。
对 172 个标本进行了 SOX11 N 端和 C 端的免疫染色。通过免疫组织化学和定量逆转录聚合酶链反应检测 cyclin D1;当需要时应用 t(11;14)原位杂交。
核 SOX11 在大多数 B 和 T 淋巴母细胞白血病/淋巴瘤和一半的儿童伯基特淋巴瘤中强烈表达,但在一些毛细胞白血病中表达较弱。慢性淋巴细胞白血病/淋巴瘤、边缘区、滤泡性和弥漫性大 B 细胞淋巴瘤均无 SOX11 表达,中间伯基特淋巴瘤/弥漫性大 B 细胞淋巴瘤、骨髓瘤、霍奇金淋巴瘤以及成熟 T 细胞和 NK/T 细胞淋巴瘤也均无 SOX11 表达。
除了套细胞淋巴瘤外,SOX11 仅在淋巴母细胞性恶性肿瘤和伯基特淋巴瘤中强烈表达。其表达独立于 cyclin D1(除了在毛细胞白血病中表达较弱),不太可能是由于淋巴肿瘤中的易位所致。
