Abstract
Precipitation of Ehrlich ascites tumor cells (EATC) by centrifugation causes ATP secretion. ATP secretion is accompanied by an increase of calcium concentration in the cytosol and persists for a long time (minutes) after centrifugation during the storage of cells at a low temperature. During prolonged storage (for more than 1.5 h), the concentration of extracellular ATP decreases to the level of ∼100 nM due to termination of secretion and ATP hydrolysis by surface ATPases. The rate of ATP hydrolysis exponentially falls with the temperature decrease from 36 to 8°C. ARL67156, a selective inhibitor of E-NTPDase-1, effectively suppresses the extracellular ATP hydrolysis. The intensity of ATP secretion does not correlate with the calcium ions concentration in the cytosol and Ca2+ mobilization from endoplasmic reticulum but correlates with the intensity of Ca2+ influx into the cells. The temperature dependences of ATP secretion intensity and Ca2+ entry rate coincide.
