Figure 4. Inhibition of cell proliferation and migration by dual treatment with SIP-SII and AZD4547. (A) Results of cell viability assays in RT112 and JMSU1 cells cultured with DMSO, 5.0 μM SIP-SII, 100 nM AZD4547, or SIP-SII and AZD4547 combined. Transwell migration assay results for RT112 (B) and JMSU1 (C) cells treated with DMSO, 5.0 μM SIP-SII, 100 nM AZD4547, or the combination of SIP-SII and AZD4547 for 24 h. Representative images at 200x magnification. Cell cycle analyses of RT112 (D) and JMSU1 (E) cells treated with DMSO, 5.0 μM SIP-SII, 100 nM AZD4547, or dual treatment with SIP-SII and AZD4547. Flow cytometry was performed 24 h post-treatment in PI-stained cells. JC-1 apoptosis assay results in RT112 (F) and JMSU1 (G) cells treated (24 h) with DMSO, 5.0 μM SIP-SII, 100 nM AZD4547, or the combination of SIP-SII and AZD4547. Data are mean ± SD (error bars) of three individual experiments. **P < 0.01 vs. DMSO; ##P < 0.01 vs. SIP-SII; ^^P < 0.01 vs. AZD4547; n = 3.
