WebRestitution of [Na+]o during the course of the calcium response greatly accelerated the rate of decay of [Ca2+]i. It is concluded that in quiescent rat ventricular myocytes, a large part of the transient increase of cytoplasmic calcium associated with reversal of the driving force of the Na+/Ca(2+)-exchanger originates from SR.
Specific signals can trigger a sudden increase in the cytoplasmic Ca 2+ levels to 500–1,000 nM by opening channels in the ER or the plasma membrane.The most common signaling pathway that increases cytoplasmic calcium concentration is the phospholipase C (PLC) pathway..
