i.e. AFB1, bioactivation of the carcinogenic mycotoxin to a toxic compound, although not acutely toxic at low concentrations, AFB1 had significant chronic effects, including protracted development, increased mortality, decreased pupation rate, and reduced pupal weight, sensitivity varies with developmental stage, whereas intermediate concentrations causes complete mortality in first instars, this same concentration has no detectable adverse effects on larvae encountering AFB1 in fifth instar. These compounds owe their toxicity to their ability to form irreversible adducts to nucleic acids with the concomitant inhibition of DNA replication and DNA-dependent transcription, mortality, overview |
