August 2013 in “Journal of Investigative Dermatology” HPT axis hormones boost mitochondrial function and growth in hair follicles, potentially aiding hair health.
116 citations
,
May 2013 in “Proceedings of the National Academy of Sciences of the United States of America” 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.
1 citations
,
November 2012 in “European Journal of Cell Biology” The authors clarified data overlap and corrected a figure error, apologizing for any confusion.
221 citations
,
July 2012 in “Proceedings of the National Academy of Sciences of the United States of America” 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.
166 citations
,
August 2010 in “Proceedings of the National Academy of Sciences of the United States of America” This study reports a less invasive method for detecting human clock gene expression using hair follicle cells, which accurately reflects individual behavioral rhythms and suggests a time lag issue for rotating shift workers.
42 citations
,
July 2010 in “European Journal of Cell Biology” This study found that thyroid hormones T3 and T4 enhance keratin 15 promoter activity and stimulate CD200 expression in epithelial stem cells from human scalp hair follicles, affecting their growth and differentiation.
66 citations
,
June 2010 in “Experimental Dermatology” This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.
55 citations
,
March 2010 in “Aging” 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.
