Abstract

Effect of the active tumor promoter, TPA, on the induction of hair follicular growth and possible neoplasia was studied histologically in normal nd precancerous mouse skin. Biweekly application of TPA resulted in nevoid proliferation of hair follicles, decreased the latent period of tumor induction, and increased the number of carcinomas of hair follicular origin in mice pretreated with MCA. The experimental tumor induction data was compared with human adnexal tumors of hair follicular origin. Similar types of animal and human lesions could be attributed to the promoter effect alone or to the dual influence of a carcinogen and promoter.

摘要

在正常和癌前小鼠皮肤中,通过组织学方法研究了活性肿瘤启动子佛波酯(TPA)对毛囊生长诱导及可能的肿瘤形成的影响。每两周应用一次TPA导致毛囊出现痣样增生,缩短了肿瘤诱导的潜伏期,并增加了经甲基胆蒽(MCA)预处理的小鼠毛囊源性癌的数量。将实验性肿瘤诱导数据与人类毛囊源性附属器肿瘤进行了比较。相似类型的动物和人类病变可能仅归因于启动子效应,或归因于致癌物和启动子的双重影响。
