Figure 2. CX-4945 inhibits TGF-β1-induced migration and invasion.

Figure 2

The effect of CX-4945 on the TGF-β1-induced migration and invasion of A549 cells was evaluated using IncuCyte software (A) and Boyden chambers (B), respectively. The red and white dashed line (A) represent the wounded area and the edge of migrated cells, respectively. Values (% RWD; Relative Wound Density) represent mean ± SD of triplicate samples and reported images are representatives of triplicate experiments. The effect of CX-4945 on the TGF-β1-induced activation of MMP-2/9 was evaluated using gelatin zymography (C), while its effect on TGF-β1-induced MMP-2/9 transcription was evaluated using real-time PCR (D). The effect of CX-4945 on the TGF-β1-induced activation of molecules such as FAK, Src, and paxillin was evaluated using Western blot analysis (E). Briefly, proteins were prepared in serum-deprived A549 cells treated with TGF-β1 (5 ng/ml) alone or in combination with CX-4945 in serum-free media for 48 h. Actin was used as a loading control. The relative, normalized ratio between phosphorylated protein and the protein itself was presented.
