Firstly, the co-expression patterns (log2-scale) between TUG1 and β-catenin (CTNNB1) in TCGA Pan-Cancer (PANCAN) showed that the expression of TUG1 was positively related to the expression of β-catenin (Figure 3A), with a Pearson coefficient r = 0.1137 and P = 0.0189 (two tail, t-test) in 426 BUC samples. This evidence concerns the gene CTNNB1 and cancer.
