Researchers have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. The circadian factors, including the principal circadian hormone melatonin, can attenuate the prenatal effects of cocaine.
