Studies using mice with beta4 nicotinic acetylcholine receptor (nAChR) subunit deficiency (beta4-/- mice) helped reveal the roles of this subunit in bradycardiac response to vagal stimulation, nicotine-induced seizure activity and anxiety. To identify genes that might be related to beta4-containing nAChRs activity, we compared the mRNA expression profiles of brains from beta4-/- and wild-type mice using Affymetrix U74Av2 microarray. Seventy-seven genes are significantly differentiated.
Genome-wide association studies are conducted of two human cohorts, one group demonstrating nicotine dependence and another successfully quitting smoking. Study shows that some genetic components associated with the ability to quit overlap while many do not overlap. To perform the study, DNA samples were obtained from NIH volunteers and the allelic frequencies of the samples were analyzed using Affymetrix array analysis. This gene set comprises 290 genes associated with nicotine dependence.

Striatum Gene Expression Correlates for LM_PS_INTVL1 measured in BXD RI Females obtained using GeneNetwork Striatum M430V2 (Apr05) RMA. The LM_PS_INTVL1 measures Activity in 30 second interval post 1st tone shock pairing under the domain Basal Behavior. The correlates were thresholded at a p-value of less than 0.001.

Genome-wide association studies are conducted of two human cohorts, one group demonstrating nicotine dependence and another successfully quitting smoking. Study shows that some genetic components associated with the ability to quit overlap while many do not overlap. To perform the study, DNA samples were obtained from NIH volunteers and the allelic frequencies of the samples were analyzed using Affymetrix array analysis. This is Table 1 aGenes that contain overlapping clusters of nominally positive SNPs in comparisons of nicotine-dependent individuals versus individuals who report use of <100 cigarettes in their lives (Hamer samples) as well as Liu/Drgon et al. and/or Beirut et al. comparisons.
