title: Modulation of chemical carcinogenesis in rats by alkyl lysophospholipids.
abstract: The influence of 1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine (ET-18-OCH3) and 1-hexadecylmercapto-2-methoxymethyl-rac-propyl-3-phosphocholine (TLP, BM41.440) on methylnitrosourea (MNU)-induced rat mammary carcinomas and of ET-18-OCH3 on 7,12-dimethylbenzanthracene (DMBA)-induced leukemias was investigated. Both agents effectively delayed MNU-induced mammary tumor formation at high, cytotoxic dosages but TLP had no influence at low "immunomodulatory" doses. ET-18-OCH3 also significantly protected against leukemia development in DMBA-treated Long-Evans rats.
