Adolescent intermittent alcohol exposure produces strain-specific cross-sensitization to nicotine and other behavioral adaptations in adulthood in C57BL/6J and DBA/2J mice
Adolescent alcohol exposure is associated with lasting behavioral changes in humans and in mice. Prior work from our laboratory and others have demonstrated that C57BL/6J and DBA/2J mice differ in sensitivity to some effects of acute alcohol exposure during adolescence and adulthood. However, it is unknown if these strains differ in cognitive, anxiety-related, and addiction-related long-term consequences of adolescent intermittent alcohol exposure. This study examined the impact of a previously validated adolescent alcohol exposure paradigm (2–3 g/kg, i.p., every other day PND 30–44) in C57BL/6J and DBA/2J male and female mice on adult fear conditioning, anxiety-related behavior (elevated plus maze), and addiction-related phenotypes including nicotine sensitivity (hypothermia and locomotor depression) and alcohol sensitivity (loss of righting reflex; LORR). Both shared and strain-specific long-term consequences of adolescent alcohol exposure were found. Most notably, we found a strain-specific alcohol-induced increase in sensitivity to nicotine's hypothermic effects during adulthood in the DBA/2J strain but not in the C57BL/6J strain. Conversely, both strains demonstrated a robust increased latency to LORR during adulthood after adolescent alcohol exposure. Thus, we observed strain-dependent cross-sensitization to nicotine and strain-independent tolerance to alcohol due to adolescent alcohol exposure. Several strain and sex differences independent of adolescent alcohol treatment were also observed. These include increased sensitivity to nicotine-induced hypothermia in the C57BL/6J strain relative to the DBA/2J strain, in addition to DBA/2J mice showing more anxiety-like behaviors in the elevated plus maze relative to the C57BL/6J strain. Overall, these results suggest that adolescent alcohol exposure results in altered adult sensitivity to nicotine and alcohol with some phenotypes mediated by genetic background.
期刊介绍：
Pharmacology Biochemistry & Behavior publishes original reports in the areas of pharmacology and biochemistry in which the primary emphasis and theoretical context are behavioral. Contributions may involve clinical, preclinical, or basic research. Purely biochemical or toxicology studies will not be published. Papers describing the behavioral effects of novel drugs in models of psychiatric, neurological and cognitive disorders, and central pain must include a positive control unless the paper is on a disease where such a drug is not available yet. Papers focusing on physiological processes (e.g., peripheral pain mechanisms, body temperature regulation, seizure activity) are not accepted as we would like to retain the focus of Pharmacology Biochemistry & Behavior on behavior and its interaction with the biochemistry and neurochemistry of the central nervous system. Papers describing the effects of plant materials are generally not considered, unless the active ingredients are studied, the extraction method is well described, the doses tested are known, and clear and definite experimental evidence on the mechanism of action of the active ingredients is provided.
