While we observed neither significant differential expression of TUG1 in UC cell lines (S2 Fig), nor in sample set 1 (Fig 1 left),nor a significant correlation between TUG1 expression and either tumour grade or stage (S3 Fig, Tables 1 and 2), TUG1 was significantly increased in the set 2 TCGA cohort (p = 0.001, Fig 1 right). Here, TUG1 is linked to neoplasm.
