Protein plays three cancer-fighting roles
The tumor suppressor protein, p53, has three ways to protect cells from turning cancerous. A new study shows that p53 helps make microRNAs.

Credit: © Bettmann/Corbis Gene therapy moves forward Despite their promise, technologies to correct defective genes have been plagued by safety problems leading to unintended — and sometimes fatal — outcomes. But scientists are inching toward safer, more effective gene therapies that may one day treat a range of diseases, from psychiatric disorders to autoimmune diseases […]

2009 Science News of the Year: Genes & Cells
Cancer-fighting roles Scientists have discovered a new role in cancer protection for an already well-known tumor suppressor protein. The protein, called p53, protects cells from becoming cancerous by sensing stress and either shutting down cell division or triggering cell death. Researchers at the University of Tokyo and colleagues have discovered that p53 also plays a […]

For a lucky few, ‘dioxins’ might be heart healthy
Dioxins and their kin are notorious poisons. They work by turning on what many biologists had long assumed was a vestigial receptor with no natural beneficial role. But it now appears that in a small proportion of people, this receptor may confer heart benefits.
