Regulation of calcium signaling in lung cancer

Haihong Yang, Qi Zhang, Jianxing He, Wenju Lu

Lung cancer is the most common malignant tumor in the world. Calcium is a ubiquitous cellular signal, which is crucial in cancer. This re- view presents regulation of calcium signaling in lung cancer. Altered expression of specific Ca2+ channels and Ca2+-binding proteins are characterizing features of lung cancer, which regulate cell signaling pathway leading to cell proliferation or apoptosis. Chemoresistance is frequent in lung cancer. Altered endoplasmic reticulum Ca2+ homeostasis of lung cancer cell is correlated with drug resistance. Hypoxia has a vital role in tumor angiogenesis, metastasis, apoptosis. And Ca2+ channels are open induced by hypoxia with the increase of Ca2+ influx causing tumor growth.
