1 PURPOSE: We identify whether tachyphylaxis and priapism effects of sildenafil are related to regulation of phosphodiesterase-5 (PDE-5) expression. Sildenafil Citrate phosphodiesterase 5A Homo sapiens
2 RESULTS: Up-regulation of PDE-5 was noted in CSMCs treated with 25 microM sildenafil for 7 days. Sildenafil Citrate phosphodiesterase 5A Homo sapiens
3 PDE-5 messenger RNA and protein levels were significantly increased in the 7-day sildenafil treated cultures. Sildenafil Citrate phosphodiesterase 5A Homo sapiens
