In addition, the antimetastatic activity of this compound in murine B16F10 melanoma cells has been demonstrated to be mediated by suppression of signal transducer and activator of transcription 3 (STAT3) phosphorylation and downregulation of STAT3 target genes MMP-2, MMP-9, VEGF, and Twist1, known to be involved in the metastatic behavior of cancer cells (186). Here, STAT3 is linked to melanoma.
