Altered intracellular Ca2 + signaling is a hallmark of cancer cells.
Several oncogenes and tumor suppressors act at the endoplasmic reticulum, the main intracellular Ca2 + store.
These proteins execute part of their functions through the modulation of intracellular Ca2 + homeostasis and dynamics.
Dysregulation of oncogenes and tumor suppressors favors oncogenic Ca2 + signaling, supporting cell survival and tolerance to cell death.
