Fig. 4. NEAT1, PSPC1, NONO, and RBM14 expression in human liver tissue. Expression of total NEAT1 and its transcript variants (A) and the transcript variants of PSPC1 (B), NONO (C), and RBM14 (D) in human tumour and non-tumour tissue from a TCGA data set. The Fig. only shows the transcript variants with an average expression rate of log2(TPM + 0.001) > 0. Results of independent two-sample t-test or Mann-Whitney test: **: p ≤ 0.01; ***: p ≤ 0.001.
