demonstrated that CIL‐102 reduced MMP‐9 expression and invasion and migration of K562 cells through simultaneous suppression of MMP‐9 genetic transcription and mRNA stability.44 Hwang et al45 proved that Kalopanaxsaponin A inhibited the invasiveness of oral cancer by reducing MMP‐9 mRNA stability and expression. Here, MMP9 is linked to lip and oral cavity carcinoma.
