research Transgneic Endothelin 3 Regulates Murine Pigment Production and Coat Color
The gene Endothelin 3 makes mice's fur darker by increasing pigment cells and pigment levels.
research Melanocyte Subpopulation Turnover During the Human Hair Cycle: An Immunohistochemical Study
Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.
research AMPK Phosphorylates ZDHHC13 to Increase MC1R Activity and Suppress Melanomagenesis
AMPK activation may reduce melanoma risk in red-haired individuals.
research Hair Follicles as a Critical Model for Monitoring the Circadian Clock
Hair follicles could be used to noninvasively monitor our body's internal clock and help identify risks for related diseases.
research Molecular Regulation of Melanocyte Senescence
The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.
research Four days of simulated shift work reduces insulin sensitivity in humans
Working night shifts for four days can lower the body's ability to use insulin, which may increase the risk of type 2 diabetes.
research Coat Color in Intact and Neurointermediate Lobe-Grafted Agouti Mice: Effect of Dopamine Agonists and Antagonists
Dopamine affects coat color changes in agouti mice.
research An update on the pathophysiology of female pattern hair loss
Female pattern hair loss involves hair follicles shrinking, influenced by hormones like melatonin and prolactin.
research Transcriptomes reveal microRNAs and mRNAs in different photoperiods influencing cashmere growth in goat
Different amounts of daylight affect cashmere growth in goats by changing the activity of certain genes and molecules.
research TTNPB Promotes Human Pluripotent Stem Cell‐to‐Neural Stem Cell Transition via Modulation of Chromatin Accessibility and the S‐(5′‐adenosyl)‐L‐homocysteine/Choline Metabolic Network
TTNPB helps turn stem cells into neural stem cells, improving depression-like behaviors in rats.
research The muscarinic acetylcholine receptor in dermal papilla cells regulates hair growth
Muscarinic acetylcholine receptors help regulate and promote hair growth.
research The efficacy of subcutaneous slow‐release melatonin implants in the prevention of canine flank alopecia recurrence is uncertain: A double‐blind, randomized, placebo‐controlled study
Melatonin implants did not effectively prevent hair loss in dogs.
research Local Actions of Thyrotropin-Releasing Hormone Regulate Hair Color
