The DNA content of 1,2-dimethylhydrazine (DMH)-induced intestinal tumors of male Wistar rats was analyzed by using flow cytometry. All adenomas and carcinomas were DNA diploid. S-phase fractions of tumors showed no significant difference from those of normal mucosae. Histological evidence of adenoma-carcinoma sequence was observed in our series. The lack of DNA aneuploidy is one of the principal differences between the DMH model and human colorectal cancers.
采用流式细胞术分析了1,2 - 二甲基肼(DMH)诱导的雄性Wistar大鼠肠道肿瘤的DNA含量。所有腺瘤和癌均为DNA二倍体。肿瘤的S期分数与正常黏膜的S期分数无显著差异。在我们的系列研究中观察到了腺瘤 - 癌序列的组织学证据。缺乏DNA非整倍体是DMH模型与人类结直肠癌之间的主要差异之一。
