  • Title: [Aneuploidy detection by multi-color fluorescence in situ hybridization in mouse sperm].
    Author: Wang X, Schmid T, Adler ID.
    Journal: Yi Chuan Xue Bao; 1999; 26(2):112-8. PubMed ID: 10375860.
    Abstract:
    Multi-color fluorescence in situ hybridization (FISH) was employed to evaluate the frequency of aneuploid sperm in young adult mice after treated by 2-(4'-thiazolyl) benzimidazole or thiabendazole (TB). The animals were given TB (100 200 300 mg/kg) by oral incubation daily for 11 days, and sacrificed 22 days after the last treatment of TB. Three-chromosome FISH was applied to determine the frequencies of diploid, disomic and nullisomic sperm with DNA probes specific for the chromosomes X, Y and 8. The aneuploid frequencies were not significantly different between the sperm in 100 mg/kg group and solvent control. The frequencies aneuploid and diploid sperm in middle dose group were significantly higher than the solvent control (P < 0.001-0.05). There were no significant aneuploid frequency increases were found in 300 mg/kg group excepting the frequency of diploid sperm. It is conclude that TB is a potential germinal aneugen in mammalian, which may block the cleavage during the meiosis. Epididymal sperm aneuploidy can be reliably determined by sperm FISH analysis in mice.
