Fig. 1

Cluster analysis of mean expression values for the up-regulated genes in AD (Br5–6) choroid plexus compared to healthy control choroid plexus (Br0–1). Cluster analysis was performed using GENE-E (version 3.0.204; analysis performed on 10/10/2015) with the “one minus Pearson correlation” and the “Average linkage method”. See also http://www.broadinstitute.org/cancer/software/GENE-E/. On the Y-axis gene names are shown, on the X-axis the individual samples. Blue and red colors indicate, respectively, relatively low and high numerical expression values. The dendograms at the top and the left side denote the (close) relationships between, respectively, the samples and the genes. Analysis parameter values are given below the figure. Both the AD and control samples cluster nicely together. Please use your PDF zoom function to evaluate details.
