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.

D004127 Dimethylhydrazines Hydrazines substituted with two methyl groups in any position. Dimethylhydrazine
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
