research Adrenal Steroid Hormone Concentrations in Dogs with Hair Cycle Arrest (Alopecia X) Before and During Treatment with Melatonin and Mitotane
Melatonin and mitotane treatment led to hair re-growth in 62% of dogs with Alopecia X, but this was not always linked to normal hormone levels.
research A Primer for Studying Cell Cycle Dynamics of the Human Hair Follicle
The document concludes that understanding hair follicle cell cycles is crucial for hair growth and alopecia research, and recommends specific techniques and future research directions.
research Characterization of Cell Cycle Arrest and Terminal Differentiation in a Maximally Proliferative Human Epithelial Tissue: Lessons from the Human Hair Follicle Matrix
CIP/KIP proteins help stop cell division and support hair growth.
research A Simple Method Using Ex Vivo Culture of Hair Follicle Tissue to Investigate Intrinsic Circadian Characteristics in Humans
Researchers developed a way to study human body clocks using hair tissue, which works similarly in both healthy and dementia patients.
research Mouse Hair Cycle Expression Dynamics Modeled as Coupled Mesenchymal and Epithelial Oscillators
The study concluded that hair growth in mice is regulated by a stable interaction between skin cell types, and disrupting this can cause hair loss.
research Human Long-Term Deregulated Circadian Rhythm Alters Regenerative Properties of Skin and Hair Precursor Cells
Disrupted sleep patterns can harm skin and hair cell renewal, but melatonin might help.
research Liver Cirrhosis and Circadian Rhythm
Taking high doses of fluconazole for a long time can cause reversible hair loss.
research Identification of Telogen Markers Underscores That Telogen Is Far from a Quiescent Hair Cycle Phase
Telogen is an active phase with important biological processes, not a resting phase.
research Diurnal Preference Predicts Phase Differences in Expression of Human Peripheral Circadian Clock Genes
An individual's morning or evening preference can predict changes in their body clock gene expression.
research What Controls Hair Follicle Cycling?
The control system for hair growth cycles is not well understood and needs more research.
research Novel Insights Into the Pathways Regulating the Canine Hair Cycle and Their Deregulation in Alopecia X
The study concluded that similar pathways regulate hair growth in dogs and mice, and these pathways are disrupted in dogs with Alopecia X, affecting stem cells and hormone metabolism.
research An Integrative Analysis of the LncRNA-MiRNA-mRNA Competitive Endogenous RNA Network Reveals Potential Mechanisms in the Murine Hair Follicle Cycle
The research found new potential mechanisms in mouse hair growth by studying RNA interactions.
research Effect of Immunization Against Melatonin on Seasonal Fleece Growth in Feral Goats
Immunizing goats against melatonin can temporarily change their cashmere growth cycles and increase fleece production.
research Change in Hair Cycle and Hair Length in Nude Mice by Administration of Deuterium Oxide
Deuterium oxide extends the hair cycle duration in mice without changing hair structure.
research Whole-Genome Bisulfite Sequencing of Goat Skins Identifies Signatures Associated with Hair Cycling
DNA methylation changes are linked to hair growth cycles in goats.
research Cyclical Dermal Micro-Niche Switching Governs the Morphological Infradian Rhythm of Mouse Zigzag Hair
Mouse zigzag hair bends form due to a 3-day cycle of changes in hair progenitors and their environment.
research The Role of Melatonin in Neuroectodermal-Mesodermal Interactions: The Hair Follicle Synthesizes Melatonin and Expresses Functional Melatonin Receptors
Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.
research Effects of Maintaining Solstice Light and Temperature on Reproductive Activity, Coat Growth, Plasma Prolactin, and Melatonin in Goats
Goat reproductive activity and coat growth are affected by light and temperature, with temperature altering prolactin levels and hair growth, but not melatonin or estrus onset.
research The Human Hair Follicle, A Bistable Organ?
Human hair follicles switch between active and resting phases unpredictably.
research Aging in Hair Follicle Stem Cells and Niche Microenvironment
Aging in hair follicle stem cells leads to hair graying, thinning, and loss.
research Molecular Insights Into Chronotype and Time-of-Day Effects on Decision-Making
People's decision-making can be influenced by their internal biological clocks, as shown by gene expression, not just self-reported preferences for morning or evening.
research An Out-Of-Lab Trial: A Case Example For The Effect Of Intensive Exercise On Rhythms Of Human Clock Gene Expression
Intense exercise at night can delay the body's internal clock gene expression by 2 to 4 hours.
research The Melanocyte Photosensory System in Human Skin
Human skin's melanocytes respond to light by changing shape, producing pigments and hormones, which may affect sleep patterns.
research The Role of Sleep in Telogen Effluvium and Trichodynia: A Commentary in the Context of the Current Pandemic
Poor sleep during the pandemic may increase stress and worsen hair loss conditions.
research Anti-Aging Medicine for Hair
Early anti-aging hair treatments should focus on anti-inflammatory agents and promoting healthy hair growth cycles.
research The Cutaneous Serotoninergic/Melatoninergic System: Securing a Place Under the Sun
Human skin can make serotonin and melatonin, which help protect and maintain it.
research Timing of Expression of the Core Clock Gene Bmal1 Influences Its Effects on Aging and Survival
The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.
research A Guide to Studying Human Hair Follicle Cycling In Vivo
The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.
research Melatonin: A Cutaneous Perspective on Its Production, Metabolism, and Functions
