Does Increasing Or Decreasing Camp Dilate Vessels? Unlike the heart, however, an increase in cAMP in vascular smooth muscle causes reduced contraction (i.e., relaxation). Does cyclic AMP causes vasodilation? Cyclic AMP and the mechanism of vasodilation have been reviewed by first discussing the enzymes involved (adenyl cyclase, cyclic nucleotide phosphodiesterases, cyclic AMP-dependent protein kinase) and
Does Increasing Camp Cause Smooth Muscle Relaxation? Unlike cardiac muscle, increased cAMP in smooth muscle causes relaxation. The reason for this is that cAMP normally inhibits myosin light chain kinase, the enzyme that is responsible for phosphorylating smooth muscle myosin and causing contraction. What happens when cAMP increases? Many different cell responses are mediated by
Can Calcium Release Stimulated Camp? The cAMP/PKA pathway promotes ryanodine receptor-mediated calcium induced calcium release, whereas cGMP and its downstream effector protein kinase G (PKG) reduces the ryanodine receptor-dependent mobilization of internal calcium stores (Ooashi et al., 2005; Tojima et al., 2009). Does calcium activate cAMP? Although cAMP can impact on Ca2 +-homeostasis at many
