research Alopecia in Harlequin Mutant Mice Is Associated with Reduced AIF Protein Levels and Expression of Retroviral Elements
Harlequin mutant mice have hair loss due to low AIF protein levels and retroviral element activity.
research Molecular Cloning and Expression Analysis of Prostaglandin E Receptor 2 Gene in Cashmere Goat (Capra hircus) Skin During Hair Follicle Development
The PTGER2 gene is highly active in Cashmere goat skin and its activity changes with the hair growth cycle.
research Advances in the Genetic Understanding of Hypohidrotic Ectodermal Dysplasia
Scientists now better understand the genetics of hypohidrotic ectodermal dysplasia, leading to more accurate diagnoses and potential new treatments.
research Stem Cells and Their Niches
The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research The Molecular Basis of Blood Diseases
The document praises a resource on hair growth disorders and recognizes a reference on blood diseases' molecular aspects as authoritative.
research Dimorphic Regulation of the MafB Gene by Sex Steroids in Hamsters (Mesocricetus Auratus)
Sex steroids affect the MafB gene differently in male and female hamsters.
research Functional Mapping of the Mouse Hairless Gene Promoter Region
Researchers found key regions in the mouse hairless gene that control its activity in skin and brain cells, affecting hair follicle function.
research Interleukin-1β Is Differentially Expressed by Human Dermal Papilla Cells in Response to PKC Activation and Is a Potent Inhibitor of Human Hair Follicle Growth in Organ Culture
IL-1β inhibits human hair follicle growth.
research Suppression of Vitamin D Receptor and Induction of Retinoid X Receptor Alpha Expression During Squamous Differentiation of Cultured Keratinocytes
As skin cells mature, vitamin D receptor levels decrease while retinoid X receptor α levels increase.
research Characterization, Genomic Organization, Expression, and Function of the mEphA1 Receptor Tyrosine Kinase
mEphA1 receptor tyrosine kinase is important for skin and hair development and may play a role in certain diseases.
research Metallothionein Expression During Wool Follicle Development in Fetal Sheep
Metallothionein likely helps in cell growth and development in wool follicles of fetal sheep.
research Conditional telomerase induction causes proliferation of hair follicle stem cells
The study demonstrated that conditional induction of TERT in mouse skin epithelium led to the proliferation of hair follicle stem cells and a transition from the resting phase to the active phase of the hair follicle cycle, resulting in robust hair growth. This effect was achieved through a novel mechanism independent of telomere synthesis, as it did not require the telomerase RNA component (TERC). The research utilized a transgenic mouse model with a tetracycline-regulated system to control TERT expression, showing that TERT activation in hair follicle epithelium consistently promoted the anagen phase with 100% penetrance in treated mice. The findings suggested that TERT could activate quiescent stem cells in the hair follicle bulge region, highlighting a non-canonical role for TERT beyond its traditional function in telomere maintenance.
research Induction of the Hair Growth Phase in Postnatal Mice by Localized Transient Expression of Sonic Hedgehog
Activating the Sonic hedgehog gene in mice can start the hair growth phase.
research A Mouse Model for the Basal Transcription and DNA Repair Syndrome Trichothiodystrophy
Researchers created a mouse with the same mutation as humans with trichothiodystrophy, showing similar symptoms and confirming the condition is due to defects in DNA repair and gene activity.
research Genetic Disorders and Defects in Vitamin D Action
Two rare genetic diseases cause severe rickets in children due to defects in vitamin D metabolism.
