We further determined the relations of TUG1 expression with knosp grade and tumor size, and the outcomes indicated that the higher knosp grade suggested a higher expression of TUG1 in PA tissue (Fig. 1C) and the larger tumors had a higher expression of TUG1 (Fig. 1D), while TUG1 expression was not changed with age and gender (Fig. 1E, F). Here, TUG1 is linked to neoplasm.
