Cordycepin has been known to inhibit MMP expressions levels (Fig. 5) through the deactivation of AP-1 via the MAPK signaling pathway (Noh et al., 2010). A study demonstrated that cordycepin blocks TNF-α- induced MMP-9 expression by decreasing the DNA-binding activity of transcription factors, such as NF-κB and AP-1 (E.J. Lee et al., 2010; S.J. Lee et al., 201). Yet another study concluded that the combination of cisplatin and cordycepin might act as a potent inhibitor of peri- toneal tumor dissemination and VEGF expression (Cai et al., 2011). Furthermore, it has been suggested that cordycepin inhibits the migra- tion and invasion of LNCaP (human prostate carcinoma) cells by down regulating the activity of TJs (tight junctions) and MMPs
