Researchers in Switzerland found a protein that alters the function of the mitochondria, the powerhouse of the cell. When the mitochondria no longer works or is depleted, the cell can no longer respirate and burn the nutrients coming into the cell. This slows the metabolism of the body. This protein is called pumilio RNA (PUM2). Aging causes the production of PUM2 to increase. High levels of PUM2 induce lower levels of another protein called mitochondrial fission factor (MFF). In turn, aging contributes to more unhealthy mitochondria in the body.

PUM2 can production can be reduced using gene-altering techniques. Besides reducing the signs of aging and increasing lifespan, lowering PUM2 will prevent the development of neuromuscular degenerative diseases.
