被撤回的出版物: LncRNA MT1JP functions as a tumor suppressor via regulating miR-214-3p expression in bladder cancer (Retracted article. See vol. 237, pg. 2592, 2022)

Growing evidence suggested that the long noncoding RNAs (lncRNAs) regulate several pathophysiological processes in tumorigenesis and may be new biomarkers for tumor therapy. In this study, we studied the expression and role of lncRNA MT1JP in the development of bladder cancer. We demonstrated that the expression of MT1JP was downregulated in bladder tumor samples and cell lines. Ectopic expression of MT1JP suppressed cell proliferation, cycle, and invasion in bladder cancer. In addition, our result suggested that miR-214-3p overexpression decreased the luciferase activity of wild-type MT1JP but not mutated-type MT1JP and elevated expression of MT1JP decreased miR-214-3p expression in the bladder cancer cell. Furthermore, we indicated that the expression of miR-214-3p was upregulated in bladder tumor samples and cell lines. Ectopic expression of miR-214-3p promoted cell proliferation, cycle, and invasion in bladder cancer. MT1JP suppressed cell proliferation, cycle, and invasion via negative modulation of miR-214-3p in bladder cancer. These data suggested that lncRNA MT1JP acts a tumor suppressor gene in bladder cancer progression, considering MT1JP as a new therapeutic target in bladder cancer.
