June 2018 in “Proceedings of the National Academy of Sciences of the United States of America” This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.
April 2018 in “Journal of Investigative Dermatology” This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.
This study found that activation of delta-opioid receptors in keratinocytes may delay the expression of the PER2 gene, suggesting a possible link to cancer development through circadian rhythm disruption.

February 2016 in “Science Translational Medicine” 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.

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.
