Neurons are genetically programmed to have long lives

When our neurons — the principal cells of the brain — die, so do we. Most neurons are created during embryonic development and have no “backup” after birth. Researchers have generally believed that their survival is determined nearly extrinsically, or by outside forces, such as the tissues and cells that neurons supply with […]

Gene-controlling mechanisms play key role in cancer progression

As cancer cells evolve, many of their genes become overactive while others are turned down. These genetic changes can help tumors grow out of control and become more aggressive, adapt to changing conditions, and eventually lead the tumor to metastasize and spread elsewhere in the body. MIT and Harvard University […]
