One gene in the heart synthesizes four peptide hormones, i.e., long-acting natriuretic peptide, vessel dilator, kaliuretic peptide and atrial natriuretic peptide. These four peptides decrease up to 97% of human pancreatic, breast, colon, ovarian, kidney and prostate adenocarcinomas as well as glioblastomas of the brain, small-cell and squamous cell lung carcinoma cells in cell culture. When infused subcutaneously for 28 days with weekly fresh hormones at 3 nM min -1 kg -1 body weight in athymic mice, they eliminate up to 80% of the human pancreatic adenocarcinomas, 2/3rds of human breast adenocarcinomas, and up to 86% of human small-cell lung cancers with treated mice living a normal lifespan. These cancers never reoccur in the primary site in the lifespan of the mice. Their mechanisms(s) of action in cancer cells includes a 95% inhibition of Ras, 96% inhibition of ERK 1/2 kinases, and 98% inhibition of MEK 1/2 kinases. Mitogens such as epidermal growth factor which stimulate Ras and ERK 1/2 kinases have their effects completely blocked by these cardiac hormones. The cardiac hormones do inhibit ERK 1/2 kinases in healthy cells. In addition to inhibiting the Ras-MEK 1/2-ERK 1/2 kinase cascade, they enter the nucleus as shown by Immunocytochemical techniques where they inhibit DNA synthesis.
