Figure 5. WP1066 combined DDP could inhibit the expression of miR-21 and its target genes.

Figure 5

ISH was used to determine the expression of miR-21 in treated OSCC cells; and Western blot was used to detect the expression of its target genes. (a) In Tca8113 and Tca8113/DDP cells, WP1066 combined with DDP treatment could inhibit MMP2/9, Bcl-2, mTOR, Ki67 expression, while in DDP + WP1066 treated group, Caspase-3 expression was upregulated. (b) In Tca8113 and Tca8113/DDP cells, WP1066 combined with DDP treatment could induce the expression of miR-21 (Red signal labeled by Cy3, cell nuclei was labeled by DAPI). IL-6 treatment could inhibit the expression of miR-21. (Bar = 20 μm) (c) In Tca8113 and Tca8113/DDP cells, DDP + WP1066 treatment could induce the expression of PTEN, TIMP3 and PDCD4. While IL-6 treatment could inhibit their expression in both cell lines. The gels were cropped, but those gels were run under the same experimental condition.
