发表于《自然》的两篇新研究报告提供了似乎是无可辩驳的证据，表明，细胞粘连分子Ｅ－钙粘着蛋白在牵制癌症方面具有重要作用。其中一篇报告指出，Ｅ－钙粘着蛋白基因的突变导致了新西兰的家族型胃癌。另一篇报告给出了转基因小鼠的实验结果，用若干种方法使小鼠丧失Ｅ－... Two new studies published in Nature provided irrefutable evidence that cell adhesion molecule E-cadherin has an important role in pinpointing cancer. One of the reports pointed out that mutations in the E-cadherin gene led to New Zealand’s familial gastric cancer. Another report gives experimental results of transgenic mice, using several methods to make mice lose E-...
