Unlocking Brain Health Secrets: Can Calorie Restriction Slow Aging?

Researchers at the Buck Institute Uncover Potential Link Between Calorie Restriction and Brain Resilience

In the quest to decipher the mysteries of aging, researchers at the Buck Institute for Research on Aging have delved into the impact of calorie restriction on brain health. The study, recently published in Nature Communications, illuminates the role of a specific gene, suggesting a potential avenue to protect the brain from aging.

Delving into Brain Aging: As we age, cognitive functions such as memory and learning inevitably face a decline. Recognizing the impact of a healthy lifestyle on brain aging, including factors like physical activity and stress management, scientists are now exploring the intriguing connection between calorie restriction and preserving brain health.

The Caloric Intervention: The research, spearheaded by Dr. Lisa Ellerby, a professor at the Buck Institute for Research on Aging, focused on understanding the effects of calorie restriction on the aging brain. Dr. Ellerby explained that given the significance of dietary restriction in the aging process, particularly concerning the vulnerable nature of the brain during aging, investigating factors influenced by calorie restriction becomes pivotal.

The Key Gene: The study utilized fruit fly models and human cells to unravel how calorie restriction influences the aging process of the brain. Through a fruit fly model with various genetic strains exposed to either a normal or 10% nutrition diet, researchers pinpointed five genes, with one standing out—the “mustard” gene in fruit flies, linked to the oxidation resistance 1 (OXR1) gene in humans.

A Closer Look at OXR1: OXR1, known for its role in responding to oxidative stress, was found to impact the retromer, a cellular complex responsible for protein and lipid recycling. This revelation challenges prior assumptions about OXR1’s function, suggesting a potential association with the aging process.

Implications for the Future: Dr. Ellerby and her team foresee these findings paving the way for potential therapeutic targets to slow aging and mitigate age-related neurodegenerative diseases. Boosting OXR1 levels, either through genetic manipulation or identifying small molecules that enhance its expression, emerges as a potential avenue for future therapeutics.

Expert Perspectives: Dr. Clifford Segil, a neurologist at Providence Saint John’s Health Center, acknowledges the study’s contribution but calls for further exploration in more complex organisms than fruit flies. He emphasizes the need for collaboration between researchers studying dietary restriction and those examining injectable weight loss medications in humans to gather comprehensive clinical data.
