Use of the phosphodiesterase 5 (PDE5) blocker sildenafil (Viagra) has been linked to an increased risk of melanoma. In a recent study we discovered a growth-promoting cGMP pathway in melanoma cells. cGMP degradation via PDE5 acts as a brake on this pathway. Inhibition of PDE5 releases this brake, providing a mechanism for the promelanoma effects of sildenafil.
磷酸二酯酶5(PDE5)阻滞剂西地那非(伟哥)的使用与黑色素瘤风险增加有关。在最近的一项研究中,我们在黑色素瘤细胞中发现了一条促进生长的环磷酸鸟苷(cGMP)信号通路。通过PDE5进行的cGMP降解对该信号通路起到制动作用。抑制PDE5可解除这种制动,这为西地那非的促黑色素瘤作用提供了一种机制。
