The protein had the same antigenicity as IgG, and the change of the protein had the same tendency as SHP-2, which was higher in canceration groups than in uncanceration groups and control groups in thymus cells, but there weren't significant change in bone marrow cells;⑧ The change law of the expression of SHP-1 and SHP-2 during γ-ray induced malignant transformation in BEAS-2B cell is that the expression of SHP-1 was increased synchronistically with malignant transformation of cell, and the expression of SHP-2 didn't have significant correlation with malignant transformation of cell.

癌变组胸腺细胞中SHP-2 mRNA编码PTPase催化区的700～1096bp间可能出现甲基化；⑦癌变组的胸腺细胞中存在一相对分子质量约为55×10〓的蛋白质，它与IgG具有相同的抗原性，其表达量的变化趋势与SHP-2的蛋白表达变化趋势基本一致，即在胸腺细胞中明显高于对照组及未癌变组，但在骨髓细胞中对照组高于癌变组；⑧SHP-1、SHP-2在γ射线诱发的BEAS-2B细胞恶性转化过程的变化规律：SHP-1蛋白表达量的升高与细胞的恶性转化在时间上基本一致，而SHP-2蛋白表达量与恶性转化无明显关系。
