In The Quest To Stymie Time, Will Laboratory Data Stand Up In Man?

In this study, researchers developed a simple, non-invasive method to monitor circadian gene expression using whole hair root cultures, finding that elderly dementia patients' peripheral clocks still oscillate similarly to younger, healthier individuals, which suggests cellular senescence minimally affects some aspects of circadian rhythms.

This article reviews the concept of caloric restriction and its potential anti-aging effects, highlighting animal studies and a human experiment in Biosphere II, but notes significant challenges for its application in humans.

Human hair follicles have a unique metabolism that changes between growth stages and may contribute to baldness.

This study found that circadian clock genes are involved in regulating the hair growth cycle, suggesting a connection between daily rhythms and the longer hair follicle cycling process.

This study found that peripheral clock genes, particularly BMAL1 and Period1, modulate human hair follicle cycling, suggesting their potential as therapeutic targets for affecting hair growth.
