   • PKA
   • Signal transduction

2. protein kinase G(English)

   • sildenafil raises myocardial PKG activity through inhibited breakdown of cyclic guanosine monophosphate. Biopsy specimens demonstrate reduced activity concentrations that is correlated with increased passive myocyte stiffness. Low PKG activity favors hypertrophy development and increases resting tension because of hypophosphorylation of titin
