Hierarchical clustering of miRNA expression in CSF, blood, and tissue RNA was
analyzed using CSF-miRNA TLDA. Cq values of each array were normalized by global
mean method. Hierarchical clustering of expression patterns was determined by
Pearson’s distance-average linkage. The heatmap indicated that miRNA
patterns of CSF were relatively similar to that of the choroid plexus, the organ
that generates CSF. CSF, blood, hippocampus, and cerebellum samples are marked
in the same colors
