The calcium sensing receptor (CaSR) is a member of the largest family of cell surface receptors, the G protein-coupled receptors involved in calcium homeostasis. The role of the CaSR in neoplasia appears to be homeostatic; loss of normal CaSR-induced response to extracellular calcium is observed in cancers of the colon and ovary, while increased release of PTHrP is observed in cancers of the breast, prostate and Leydig cells. Currently CaSR can be considered as a molecule that can either promote or prevent tumor growth depending on the type of cancer. Therefore, recognition of the multifaceted role of CaSR in gliomas and other malignant tumors in general is fundamental to elucidating the mechanisms of tumor progression and the development of novel therapeutic agents. Emphasis should be placed on development of drug-targeting methods to modulate CaSR activity in cancer cells.Keywords: CaSR -GPCR -metastasis -PTHrP -homeostasis -cancer cells MINI-REVIEW Calcium Sensing Receptor Modulation for Cancer TherapyPuja Sarkar, Sudhir Kumar* and migration in tumor cells. Herein, we review the role of calcium sensing receptor (CaSR) in the development and metastasis of cancer and manipulation of the receptor for the treatment of cancers in the future.
