Ca<sup>2+</sup> oscillations that depend on inositol-1,4,5-trisphosphate (IP<sub>3</sub>) have been ascribed to biphasic Ca<sup>2+</sup> regulation of the IP<sub>3</sub> receptor (IP<sub>3</sub>R) or feedback mechanisms controlling IP<sub>3</sub> levels in different cell types. IP<sub>3</sub> uncaging in hepatocytes elicits Ca<sup>2+</sup> transients that are often localized at the subcellular level and increase in magnitude with stimulus strength. However, this does not reproduce the broad base ...[more]
