Experimental validation of DE lncRNAs. Upper part of panel displays the expression levels of the indicated lncRNAs in the TCGA analyses. The nonparametric Mann–Whitney test was applied due to the non-Gaussian expression distribution and p-value was assigned. Lower part of panel displays the experimental validation of these lncRNAs measured by qRT-PCR and calculated with 2−ΔΔCt method using RPL19 (Ribosomal Protein L19) as endogenous control. Experiments with three biological replicates were performed using two technical replicates for each sample. These results are representative of at least two independent experiments. Values are plotted as expression mean ± Standard Error of Mean (SEM). Unpaired two-tailed t-Test assigned the p-value.
