In this study, we demonstrate 67LR activated the peculiar apoptotic signalling eNOS/NO/ cGMP/protein kinase Cδ (PKCδ) pathway. Furthermore, we show the upregulation of cGMP is rate-determining process of this cell death pathway. We demonstrate cancer overexpressed negative regulator of cGMP, PDE5 attenuates the cGMP-dependent cell death induced by EGCG. Vardenafil, one of the PDE5 selective inhibitors used for treating erectile dysfunction potentiates anti-cancer effect of EGCG. These results demonstrate that cGMP elevation caused by targeting the overexpressed 67LR and PDE5 in cancer cells may be a useful approach for cancer-specific chemotherapy.
