Regulation of Notch pathway in MM cells treated by GANT61 with different treatment times. mRNA expressions of Notch pathway-related factors (including Notch1, Jagged1, Jagged2, Hes1) after treated by 10 μmol/L GANT61 with different treatment times (0, 18, 24, 36 h) in RPMI-8226 cells (a). Protein expressions of Notch pathway-related factors (including Notch1, Jagged1, Jagged2, Hes1) after treated by 10 μmol/L GANT61 with different treatment times (0, 18, 24, 36 h) in RPMI-8226 cells (b, c). mRNA expressions of Notch pathway-related factors (including Notch1, Jagged1, Jagged2, Hes1) after treated by 10 μmol/L GANT61 with different treatment times (0, 18, 24, 36 h) in U 266 cells (d). Protein expressions of Notch pathway-related factors (including Notch1, Jagged1, Jagged2, Hes1) after treated by 10 μmol/L GANT61 with different treatment times (0, 18, 24, 36 h) in U266 cells (e, f). Comparison between two groups was determined by t-test. P value < 0.05 was considered significant. *P < 0.05; **P < 0.01; ***P < 0.001. MM, multiple myeloma.
