We searched for genes differentially expressed in the frontal cortices of Alzheimer-type dementia (ATD) patients compared with those of non-ATD controls using DNA microarray and quantitative reverse transcription-polymerase chain reaction (RT-PCR) analyses. Here we show that the expression level of the autotaxin (also called lysophospholipase D or ecto-nucleotide pyrophosphatase/phosphodiesterase 2) gene was significantly Mater in ATD cortices than in non-ATD cortices. In both ATD and non-ATD groups, the expression levels were greater in patients with the apoE epsilon 3/epsilon 4 genotype than in patients with the apoE epsilon 3/epsilon 3 genotype, although the differences were not statistically significant. These observations suggest that expression of the autotaxin gene and cell signaling by lysophosphatidic acid may be involved in the pathology of ATD, and that this cell signaling pathway may be a potential target of treatments for ATD.
