Unlike Orai1, Orai3 expression is significantly enhanced in bronchial biopsies after treatment with cisplatin, which shifts the Orai1:Orai3 expression ratio in favor of Orai3, enhances SOCE, and is associated with the expression of cancer stem cells markers, Nanog and SOX-2, most likely mediated by a mechanism dependent on the activation of the PI3K/AKT pathway [51]. This evidence concerns the gene ORAI3 and cancer.
