EGCG nanoparticles had proapoptotic and antiangiogenetic effects on 22Rr1 cells [306], inhibited tumour growth in PC-3 cells [307], induced apoptosis and reduced viability of DU-145 cells [308], and inhibited tumour growth and secretion of PSA by increase of Bax, induction of poly (ADP-ribose) polymerases cleavage, and activation of caspases and apoptosis [309,310]. Here, KLK3 is linked to neoplasm.
