EMSLR and urinary bladder carcinoma: We also evaluated the expression pattern of lncRNA BCCE4 based on an in‐house dataset, TCGA database, and cell lines (SV‐HUC‐1, EJ, and J82), and the results showed increased lncRNA BCCE4 expression levels in bladder cancer tissues, patients with high‐grade tumors and bladder cancer cells (Figure 2G–I; and Figure S8A, Supporting Information).
