MALAT1 regulates miR-124/foxq1 cascade expression in BTCC cells. The relative expression of MALAT1, miR-124, and foxq1 was examined using real-time PCR and western blot in T24 cells and BIU-87 cells. Data are shown as mean ± SEM. Real-time PCR analysis of MALAT1, miR-124, and foxq1 mRNA expression in T24 cells (A) and BIU-87 cells (B) transfacted with Control, MALAT1, respectively. Real-time PCR analysis of MALAT1, miR-124, and foxq1 mRNA expression in T24 cells (C) and BIU-87 cells (D) transfacted with Scramble, si-MALAT1, respectively. (E) Western blot analysis of foxq1 expression in T24 and BIU-87 cells both transfacted with Control, MALAT1+miR-124, respectively. (F) Western blot analysis of foxq1 expression in T24 and BIU-87 cells both transfacted with Scramble, si-miR-124+si-MALAT1, respectively. *P < 0.05.
