The regulatory roles of calcium channels in tumors.

Calcium (Ca ²⁺ ) and its relevant transmembrane and intracellular calcium channels were previously thought to be chiefly associated with the regulation of cardiovascular and neuronal systems. Nowadays, an increasing evidence shows those calcium channels are also responsible for tumorigenesis and progression. However, the general underlying mechanisms and the involving signaling transduction pathways still remain unclear. Therefore, in this mini-review, we are mainly focusing on the linkage between calcium channels and major characteristics of tumors such as multi-drug resistance (MDR), metastasis, apoptosis, proliferation, evasion of immune surveillance, and the alterations of tumor microenvironment. We will shed light on the possible therapeutic approaches to counteract tumors regarding the intervention of calcium channel.
