Cell cycle variations and DNA aneuploidy, were investigated in different phases of azoxymethane (AOM)-induced colon carcinogenesis in rats by flow cytometry. K-ras gene mutations (transitions Gright curved arrow A) were frequently detected in aberrant crypt foci (ACF) initial pre-neoplastic lesions. The fraction of cells in the G2M-phase of the cell cycle was higher in ACF compared to the normal mucosa of control rats. A similar modification of the cell cycle was found in adenomas and adenocarcinomas but, unexpectedly, also in morphologically normal mucosa from AOM-treated animals indicating that AOM treatment permanently modifies cell cycle control in rat colon mucosa. These alterations, however, were not associated with DNA aneuploidy as reported in human sporadic colorectal cancer, suggesting that tumour development in AOM-treated rats is less dependent on aneuploidy.
