Activation of IP3R in atrial cardiomyocytes leads to generation of cytosolic cAMP

E. C. Akerman, M. J. Read, S. J. Bose, A. Koschinski, R. A. Capel, Y.-C. Chao, M. Folkmanaite, S. Hester, R. Fischer, T. Ayagama, S. D. Broadbent, R. Ahamed, J. N. Simon, D. A. Terrar, M. Zaccolo, R.-A. B. Burton

This study shows that IP3R activation in atrial myocytes increases cAMP, which can be inhibited by IP3R blockers, but ventricular myocytes show cAMP increases independent of IP3R.

Cross-talk between cAMP and Ca2+ signalling in cardiac pacemaker cells involves IP3-evoked Ca2+ release and stimulation of adenylyl cyclase 1

S. J. Bose, M. Read, R. A. Capel, E. Akerman, T. Ayagama, A. Russell, D. A. Terrar, M. Zaccolo, R. A. B. Burton

This study investigates the role of AC1 in atrial pacemaker activity response to β-adrenergic stimulation and IP3R calcium release in mouse and guinea pig atrial tissues.

cAMP signalling is required for the actions of IP3 on Ca2+-transients in cardiac atria and beating rate in sino-atrial node

R. A. Capel, T. Collins, S. J. Bose, S. Rajasundaram, T. Ayagama, M. Zaccolo, R. A. Burton, D. A. Terrar

The paper investigates the interaction between IP3 and cAMP signaling in cardiac atria and sino-atrial node, showing that IP3 enhances Ca2+ transients and beating rate through AC activation.
