Scientists recently discovered an anti-aging hormone called Klotho. Now, a new study shows that this protein acts by increasing the cell's ability to detoxify harmful reactive oxygen species. The research appears as the "Paper of the Week" in the November 11 issue of the Journal of Biological Chemistry, an American Society for Biochemistry and Molecular Biology journal.

A newly discovered antiaging hormone has been found to work at least in part by increasing cells' ability to detoxify harmful reactive oxygen species.

WebMD takes a look at a recent study on the biochemistry of calorie restriction: "The results showed that mice that were fed 30% to 40% fewer calories produced more nitric oxide than those who followed an unrestricted diet. Calorie restriction also caused the mice to increase production of another chemical messenger that stimulated production of new mitochondria (the main energy source in cells) and increased oxygen consumption and expression of a protein previously shown to play a role in calo

A detectable decline in energy production by mitochondria -- the organelles that are the cell's furnace for energy production -- seems to be a key problem leading to insulin resistance, and thus to type 2 diabetes, according to studies by Howard Hughes Medical Institute researchers.

University of Florida professor Christiaan Leeuwenburgh wants you to get older. Leeuwenburgh, chief of UF's department of aging and geriatric research, said the average human life span could increase by up to 30 years with proper diet and exercise.

The organisation of a key cellular energy-producing enzyme has been revealed by a team of scientists from the Medical Research Council (MRC) Dunn Human Nutrition Unit in Cambridge, UK. The discovery has potential implications for understanding human ageing and is published in the current issue of the journal Science.

While medical science and a healthy lifestyle can help increase life expectancy, many aspects of aging and longevity are beyond our control. Published this week in the open-access journal PLoS Biology, Michael Eisen and colleagues shed light on these genetic factors by identifying sets of genes whose expression changes with age in human and chimp brains.
