Intergenerational Effects Of Nicotine In An Animal Model Of Paternal Nicotine Exposure, Markus Parzival Vallaster Aug 2017

Intergenerational Effects Of Nicotine In An Animal Model Of Paternal Nicotine Exposure, Markus Parzival Vallaster

GSBS Dissertations and Theses

Environmental conditions imposed onto organisms during certain phases of their life cycles such as embryogenesis or puberty can not only impact the organisms’ own health, but also affect subsequent generations. The underlying mechanisms causing intergenerational phenotypes are not encoded in the genome, but the result of reversible epigenetic modifications. This work investigates in a mouse model the impact of paternal nicotine exposure on the next generation regarding addictive behavior modulation, metabolic changes, and molecular mechanisms. It provides evidence that male offspring from nicotine-exposed fathers (NIC offspring) is more resistant to lethal doses of nicotine. This phenotype is gender-specific and depends ...
