Figure 4: The hierarchical clustering of the differentially expressed lncRNAs (a) and mRNAs (b) in AD(n = 3/group) and control(n = 3/group) hippocampal tissues. (c) and (d) The quantitative real-time PCR (qRT-PCR) validated 4 randomly selected lncRNAs and mRNAs. The qRT-PCR results were consistent with the microarray data. (c) lncRNAS. (d) mRNAs.
