Moreover, oncogenic BRAF mutation was shown to down-regulate PDE5A through the RAS/RAF/MEK/ERK signaling, and PDE5A down-regulation can stimulate a dramatic increase in melanoma cell contractility and invasion despite causing a slight decrease in proliferation.8,11 Among 10 BRAF-mutant cell lines, Arozarena et al did not find down-regulated PDE5A messenger RNA or protein expression in the 501mel cell line, in which sildenafil use induced invasion. In contrast, they did not observe increased invasion of A375 or WM266.4 cells by sildenafil, whereas both were BRAF mutated and had suppressed PDE5A expression.8 These data suggest that either RAS/RAF activation or sildenafil can inhibit PDE5A activity. Sildenafil could act in the MEK/ERK downstream, acting similarly with one signal induced by RAS/RAF activation, and the effect of sildenafil on melanoma may not involve the RAS/RAF mutations/activation.8 Whether the presence of both RAS/RAF mutations/activation and PDE5A inhibitors could trigger a synergistic or antagonistic effect remains to be investigated.have or have had heart problems such as a heart attack, irregular heartbeat, angina, chest pain, narrowing of the aortic valve or heart failure
