Family-based study of the association of the dopamine D2 receptor gene (DRD2) with habitual smoking.
A recent study showed an association between the dopamine D2 receptor gene (DRD2) and smoking. The purpose of this study was to determine if the familial transmission of smoking is linked to variation at the DRD2 locus in a genetically informative sample. Subjects were identified in alcohol treatment centers and their relatives were recruited for study. All subjects were interviewed to assess a...
متن کاملA family-based analysis of the association of the dopamine D2 receptor (DRD2) with alcoholism.
The possible association of the DRD2 locus, and in particular the Taql-A1 allele, with alcoholism remains controversial, in part because of differences in allele frequencies among populations. To avoid problems associated with differences in allele frequencies in different populations, we tested whether the DRD2 locus is associated with alcohol dependence in a large family-based sample. Neither...
متن کاملIncreased dopamine D2 receptor activity in the striatum alters the firing pattern of dopamine neurons in the ventral tegmental area.
There is strong evidence that the core deficits of schizophrenia result from dysfunction of the dopamine (DA) system, but details of this dysfunction remain unclear. We previously reported a model of transgenic mice that selectively and reversibly overexpress DA D2 receptors (D2Rs) in the striatum (D2R-OE mice). D2R-OE mice display deficits in cognition and motivation that are strikingly simila...
متن کاملVentral striatum binding of a dopamine D2/3 receptor agonist but not antagonist predicts normal body mass index.
BACKGROUND Positron emission tomography research has shown that dopamine D2/3 receptor (D2/3R) availability is negatively correlated with body mass index (BMI) in obese but not in healthy subjects. However, previous positron emission tomography studies have not looked specifically at the ventral striatum (VS), which plays an important role in motivation and feeding. Furthermore, these studies h...
متن کاملSodium ion modulates D2 receptor characteristics of dopamine agonist and antagonist binding sites in striatum and retina.
Sodium ion (Na(+)) influences binding of both dopamine agonists and antagonists to D(2) receptors in striatum and retina. Also, Na(+) markedly potentiates the loss of high-affinity agonist binding due to the GTP analogue p[NH]ppG. 2-Amino-6, 7-dihydroxy-1,2,3,4-tetrahydro[5,8-(3)H]naphthalene ([(3)H]ADTN) binds exclusively to an agonist conformation of D(2) receptor in both striatum and retina,...
