我比较相信国外做的研究:
Heterogeneity of bcl-2 expression in MALT lymphoma.
bcl-2在Malt淋巴瘤中的异质性的表达
Abstract 摘要
Bcl-2 protein expression was studied in a series of 58 MALT lymphomas using a monoclonal antibody which recognises this protein in routinely processed paraffin embedded tissue. Thirty-three of 58 cases showed heterogeneity for bcl-2 expression, 18 of 58 cases were bcl-2 positive and 7 of 58 were bcl-2 negative. High grade and low grade MALT lymphomas showed different patterns of staining. All 21 low grade tumours were positive for bcl-2, though in seven cases only a proportion of the neoplastic cells expressed this protein. In the 37 high grade tumours the majority of the neoplastic cells were negative with seven cases showing no reactivity at all. These findings give further support to the theory that MALT lymphomas differ in pathogenesis to nodal lymphomas and suggest that the good prognosis of MALT lymphomas may partly be explained by the fact that they maintain a normal pattern of bcl-2 expression.
用一种能够在日常处理的蜡块中识别这种蛋白的单克隆抗体对58例MALT淋巴瘤的bcl-2蛋白表达进行了研究。在58例淋巴瘤中,33例有不同程度的表达,18例是bcl-2阳性,7例阴性。高级别和低级别的MALT显示出了不同的染色结果。全部21个低级别的肿瘤都是bcl-2阳性,尽管其中有7例只有部分肿瘤细胞表达这种蛋白。37例高级别的肿瘤中绝大多数肿瘤细胞是阴性,有7例完全没有染色反应。这个发现进一步证实了关于MALT与结节型淋巴瘤发病机制不同的理论,并且提示MALT较好的预后也许可以用其维持了正常的bcl-2表达来解释。 |
