Chronic Smoking and Alcoholism Change Expression of Selective Genes in the Human Prefrontal Cortex

Flatscher‐Bader, Traute, Wilce, Peter A.·2006·Alcoholism: Clinical and Experimental Research

Abstract

Background:Alcoholism is commonly associated with chronic smoking. A number of gene expression profiles of regions within the human mesocorticolimbic system have identified potential alcohol‐sensitive genes; however, the influence of smoking on these changes was not taken into account. This study addressed the impact of alcohol and smoking on the expression of 4 genes, previously identified as alcoholism‐sensitive, in the human prefrontal cortex (PFC). Methods:mRNA expression of apolipoprotein D, tissue inhibitor of the metalloproteinase 3, high‐affinity glial glutamate transporter and midkine, was measured in the PFC of alcoholic subjects and controls with and without smoking comorbidity using real‐time polymerase chain reaction. Results:The results show that alcohol affects transcription of some of these genes. Additionally, smoking has a marked influence on gene expression. Conclusion:This study emphasizes the need for careful case selection in future gene expression studies to delineate the adaptive molecular process associated with smoking and alcohol.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
