Abstract: Tobacco addiction affects millions throughout the world, and kills up to 50% of its users according to the World Health Organization. Nicotine is the primary compound in tobacco that has been associated with the addictive properties of this drug. Nicotine is known to adversely affect the offspring of mothers exposed to nicotine during gestation. Although the receptors for nicotine are known, the genetic, cellular and molecular mechanisms that mediate nicotine's effects on development are not well understood. Drosophila melanogaster is a great and proven model system to identify genes and novel mechanisms for drugs of abuse. My lab has developed a Drosophila model for the effects of developmental nicotine exposure. Developmental nicotine exposure has specific effects on Drosophila development and behavior that are similar to those reported in mammals, including humans. The conservation in receptors and neurotransmitters that mediate the effects of nicotine make this organism a suitable model system to elucidate novel mechanisms for nicotine’s effects.
