A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

With 1/8 deaths due to a substance of abuse worldwide, addiction is a public health priority, but its pathophysiology remains poorly understood. Genetic modifications of nAChR α5 subunit alter nicotine and cocaine self-administration in rodents (Besson, Forget et Maskos – NISC), and variants in this gene have repeatedly been associated with nicotine, cocaine and alcohol addiction in Humans. We aimed to extend these findings with a series of genotype/phenotype association studies in 491 Caucasian outpatients with severe addictions, considering the nicotinic pathway from a genome-wide DNA microarray. We focused on phenotypes corresponding to rodent self-administration stages. Early relapse of cocaine addiction was associated to a variant in the chaperone protein gene RIC-3 and the polymorphism rs16969968 to more cigarettes smoked/day (both corrected p < 0.05). We will extend this collaboration through a translational research program submitted to the ANR.
