Three different methodologies have been applied to microarray data
from brains of Alzheimer diagnosed patients and healthy patients
taken as control. A clear pattern of differential gene expression
results which can be regarded as a molecular signature of the
disease. The results show the complementarity of the different
methodologies, suggesting that a unified approach may help to
uncover complex genetic risk factors not currently discovered with
a single method. We also compare the set of genes in these
differential patterns with those already reported in the
literature.
