  • Title: Testing for the chemical induction of aneuploidy in the male mouse.
    Author: Brook JD, Chandley AC.
    Journal: Mutat Res; 1986 Apr; 164(2):117-25. PubMed ID: 3960041.
    Abstract:
    Dyad scores of metaphase II spermatocytes in the mouse have been used as an end point to assess the aneuploidy-inducing potential of three different chemicals; p-fluorophyalanine, phenylalanine and 6-mercaptopurine. The sensitivities of three different spermatogenic stages have been tested; pre-leptotene, zygotene and metaphase I. No effect was found at any treated stage for 6-mercaptopurine and phenylalanine. p-Fluorophenylalanine, when compared to control treatments, did, however, induce non-disjunction when applied at metaphase I. It also caused a delay to spermatogenesis when applied at this stage. The potential of mammalian test systems for the routine screening of chemicals as non-disjunction inducers, is discussed.
