Research provides new insights into longevity

Scientists are always looking for ways to improve longevity, allowing people to not only live longer but enjoy life longer. While a recent study did not end with scientists discovering a new secret to an extended lifespan, it did have an interesting result that advanced longevity research.

The study, from The University of Texas Health Science Center San Antonio, challenged previously held beliefs that lacking a copy of a gene known as the IGF1 receptor, used in insulin signaling, could increase longevity.

The research concluded that eliminating one copy of the gene failed to increase the life span of male mice and only modestly increased the longevity of female mice.

"This demonstrates that reducing insulin signaling through the IGF1 pathway in mammals does not play the same role in aging that is observed in invertebrates," said Dr. Martin Adamo, professor of biochemistry at the school.

The study was released in the November 23 issue of the journal PLoS ONE and was conducted by Adamo along with Dr. Arlan Richardson, a University of Texas professor of cellular and structural biology.

Longevity is likely to be on the minds of senior citizens and aging baby boomers. When it comes to long-term financial security, a life insurance policy should be in place to protect the monetary future of the policyholder's loved ones and dependents.
