However, downregulation of PAI-1 expression by miR-143 and -145 was also confirmed in other cancer cell lines, including H1299 (non-small cell lung carcinoma), HeLa (cervical cancer) and U251 (glioma cell line), thereby demonstrating that miR-143/-145-directed repression of PAI-1 is not restricted to bladder cancer (Supplementary Figure 2). The gene discussed is SERPINE1; the disease is urinary bladder cancer.
