Expression of lncRNAs CASC9 and HOTAIR in different HNSCC tissue sets. Boxplot representations of lncRNA expression measured by RT-qPCR (relative expression to geometric mean of reference genes SDHA and TBP) in sets DUS (a) and BN (b) and by RNA-Seq in set TCGA (c) (public data from the TCGA HNSCC cancer cohort obtained from the TANRIC database; expression as log2 RPMK). P-values for difference between control (N) and tumor (T) samples were calculated by Mann-Whitney U-test
