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 discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This study found that transgenic mice expressing a mutant CYLD protein lacking deubiquitinase function showed signs of premature aging and spontaneous tumor development, likely due to over-activation of specific molecular pathways and chronic inflammation.

This study concluded that the expression of clock genes, specifically BMAL1, in hair follicles is linked to circadian rhythm, and BMAL1 regulates hair growth.

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.

This study observed that deleting PTEN in mouse facial motoneurons enhanced peripheral axon regeneration but also led to physiological changes and potential hyperplasia in older mice.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This review discusses the role of circadian rhythms in stem cell differentiation and tissue regeneration, emphasizing their impact on organ physiology and aging, but reports no new experimental results.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

In this review, the authors discussed how the circadian clock influences hair follicle regeneration by regulating metabolism, suggesting potential new targets for hair loss treatments.

This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.

In a study on mice, researchers found that exposure to artificial light environments causing circadian misalignment impaired hair growth by reducing the hair growth rate during the anagen phase, suggesting these light conditions as a potential risk factor for hair loss.

GNPTAB gene is crucial for normal hair color in humans and mice.

The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.

This review discusses the role of telomere length dynamics in hair follicle biology and reports no new clinical findings, emphasizing the need for further research in humans.

This pilot study suggests that a new preparation of platelet-rich plasma gel may improve symptoms and tissue regeneration in patients with en coup de sabre scleroderma, though further trials are needed to clarify its role.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.
