“…,ATO markedly increased the resting Ca2+ ratio, amplitude/resting calcium, the maximal velocity of Ca2+ shortening and relaxation (+d[Ca2+]/dtmax and -d[Ca2+]/dtmax), time-to-50% peak [Ca2+] i and the decay rate of [Ca2+] i transients, suggesting that ATO leads to intracellular imbalance of calcium homeostasis.”
