Tumor Suppressor Par-4

Par-4 is a tumor suppressor protein first discovered and identified in 1993 by Dr. Vivek Rangnekar’s laboratory in prostate cancer cells undergoing apoptosis.  Par-4 (later also known as PAWR) is a naturally occurring tumor suppressor. Studies have indicated that Par-4 selectively induces apoptosis in cancer cells while leaving normal, healthy, cells unaffected. Mechanisms contributing to the cancer-selective action of Par-4 have been associated with protein kinase A activation of intrace
