It has been reported that Gal‐3 silencing in cultured human tongue cancer cells led to a decrease in MMP‐9 protein levels52 and interestingly, we found here that MMP‐9 was reduced in SKOV3 treated with Pect‐MCP and both MMP‐2 and ‐9 were strongly decreased in the presence of Pect‐MCP + PTX. This evidence concerns the gene MMP9 and tongue cancer.
