Abstract Title:
Genotoxic and Genoprotective Potential of Black Mulberry (Morus nigra) Fruit.
Abstract:
Black Mulberry (Morus nigra L.) belongs to Moraceae family. The present study evaluated the possible genotoxic and/or protective activities of black mulberry fruit juice (BMFJ), in vitro, using mitomycin C (MMC) as a positive control, by chromosomal aberrations and micronucleus assays. Human lymphocytes were treated with BMFJ concentrations alone (1/1, 1/2, 1/4, 1/8 dilutions), pretreatment (49h) (0.20μg/ml MMC+ 1/1 BMFJ, 0.20 μg/ml MMC+1/2 diluted BMFJ, 0.20 μg/ml MMC+1/4 diluted BMFJ, 0.20 μg/ml MMC+1/8 diluted BMFJ) and simultaneous-treatment (48h) (0.20 μg/ml MMC+ 1/1 BMFJ, 0.20 μg/ml MMC+1/2 diluted BMFJ, 0.20 μg/ml MMC+1/4 diluted BMFJ, 0.20 μg/ml MMC+1/8 diluted BMFJ). The in vitroresults demonstrated that BMFJ showed no genotoxicity, but it significantly decreased chromosomal aberration and micronucleus frequency induced by MMC. Our results showed that all concentrations of BMFJ revealed no genotoxicity but protective activity against genomic changes induced by anti-tumoragent MMC in human lymphocytes. Protective effects of BMFJ on MMC induced chromosomal damages most probably due to its free radical scavenging activity.
