Abstract
We recently unraveled a finely tuned oncogenic mechanism in which genetic and tumor microenvironment alterations act together on a crucial calcium signaling pathway. This pathway involves an interconnected equilibrium of calcium channels functioning like a binary star system in which ORAI1 homomers and ORAI1/3 heteromers are two companion stars under the influence of each other that orbit around the cancer hallmarks of apoptosis resistance and enhanced proliferation.
