The combined treatment of curcumin and paclitaxel significantly suppressed the paclitaxel-mediated NF-κB expression and its regulatory genes COX-2, matrix metallopeptidase 9 (MMP-9), VEGF, and intercellular adhesion molecule 1 (ICAM-1), thus promoting the anti-proliferative and anti-metastatic behaviour in breast cancer cells [68,152]. Here, MMP9 is linked to breast cancer.
