Potential therapeutic applications of phosphodiesterase inhibition in prostate cancer

Objective Phosphodiesterases (PDEs) play a role in controlling cyclic nucleotide action, including cyclic guanosine monophosphate (cGMP). Previous studies have ascribed a protective role of cGMP signaling on hypoxia-mediated cancer progression. Herein, we determine their potential role in hypoxia-mediated chemoresistance and immune escape.
