U.S. researchers have discovered a gene that suppresses tumor growth in melanoma, the deadliest form of skin cancer. In a new study, scientists at the National Institutes of Health found that one-quarter of human skin cancer tumors had mutations in genes that code for matrix metalloproteinase (MMP) enzymes. The researchers say their findings may pave the way for more individualized cancer treatment strategies where MMP and other key enzymes play a role in tumor growth and spread of the disease.
