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.
92 citations
,
September 2013 in “Journal of Investigative Dermatology” 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.
293 citations
,
November 2011 in “Nature” 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.
38 citations
,
August 2012 in “Biochemical and biophysical research communications” This study found that leukocytes and beard hair follicle cells have an endogenous circadian clock, with PER1 and PER3 expression possibly serving as biomarkers for assessing individual biological clock traits.
