Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths worldwide. Researchers have observed expression of CB1 (24%) and CB2 (55%) in NSCLC patients. They have also shown that the treatment of NSCLC cell lines (A549 and SW-1573) with CB1/CB2- and CB2-specific agonists Win55,212-2 and JWH-015, respectively, significantly attenuated random as well as growth factor-directed in vitro chemotaxis and chemoinvasion in these cells.[6]
