Figure 4. Effects of DIM and Herceptin on miR-200 family.

Figure 4

(A) Comparative expression analysis of miR-200 in SKBR3 and MDA-MB-468 cells by real-time miRNA RT-PCR. (B and C) Relative expression analysis of miR-200 in SKBR3 and MDA-MB-468 cells treated with 15 µM DIM, 0.75 µg/ml Herceptin or their combinations for 24 h. (D) Effect of anti-miR-200s (anti-miR-200a+anti-miR-200b+anti-miR-200c) on cell proliferation of SKBR3 cells treated with 15 µM DIM and 0.75 µg/ml Herceptin for 72 hours, as measured by MTT assay. (E) Efficacy of anti-miR-200s transfections as well the effect of DIM plus Herceptin (15 µM DIM and 0.75 µg/ml Herceptin for 72 hours) on expression levels of anti-miR-200s (miR-200a/miR-200b/miR-200c) was evaluated by real time RT-PCR. (F) Effect of anti-miR-200s (anti-miR-200a+anti-miR-200b+anti-miR-200c) on expression of FoxM1 and pAkt in SKBR3 cells treated with 15 µM DIM and 0.75 µg/ml Herceptin for 72 hours, as determined by western blotting. The numbers represent percent of corresponding control normalized to β-actin levels. Her, Herceptin; anti-miR-200s, anti-miR-200a+anti-miR-200b+anti-miR-200c. *, P<0.05 and **, P<0.01 relative to control.
