research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research A Mouse Model for Conditional Expression of Activated β-Catenin in Epidermal Keratinocytes
Activated β-catenin affects hair growth and skin thickness, and changes are reversible.
research In situ tensile deformation characterization of human hair with atomic force microscopy
AFM helped show how hair changes under tension and the effects of damage and conditioner.
research Rapid mechanosensitive migration and dispersal of newly divided mesenchymal cells aid their recruitment into dermal condensates
Newly divided skin cells quickly move to join skin structures due to tissue tension and specific signals.
research Ornithine Decarboxylase Expression Leads to Translocation and Activation of Protein Kinase CK2 in Vivo
High ornithine decarboxylase levels may lead to hair loss and cancer by increasing CK2 activity in the nucleus.
research Minoxidil Sulfation in the Hair Follicle
Minoxidil helps hair growth by activating enzymes in hair follicles.
research Physiologic functions of PP2A: Lessons from genetically modified mice
Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.
research Basement Membrane Zone Remodeling During Appendageal Development in Human Fetal Skin. The Absence of Type VII Collagen is Associated with Gelatinase-A (MMP2) Activity
Type VII collagen absence helps skin development by allowing tissue remodeling.
research Collagenase IV plays an important role in regulating hair cycle by inducing VEGF, IGF-1, and TGF-β expression
Collagenase IV is crucial for hair growth by affecting key growth factors.
research Topological Distribution of Wound Stiffness Modulates Wound-Induced Hair Follicle Neogenesis
The stiffness of a wound affects hair growth during healing, with less stiff areas growing more hair.
research Androgen receptor transactivity is potentiated by TGF-β1 through Smad3 but checked by its coactivator Hic-5/ARA55 in balding dermal papilla cells
TGF-β1 increases androgen receptor activity in hair loss, but Hic-5/ARA55 can counter this effect.
research L-Ornithine ketoacid-transaminase assay in hair roots of homozygotes and heterozygotes for gyrate atrophy
research 507 Trial to investigate the role of ATP-sensitive potassium channels (KATPc) in dermal papilla cells (DPCs)
ATP-sensitive potassium channels are important for hair growth.
research Direct hair growth promoting effects of mycophenolic acid
Mycophenolic acid may help hair grow by activating pathways important for hair growth.
research Androgen regulation of a specific gene in hamster flank organs
Male hormones control a specific gene in hamster skin, with different hormones having varying effects.
research Overexpression of protein kinase C-α in the epidermis of transgenic mice results in striking alterations in phorbol ester-induced inflammation and COX-2, MIP-2 and TNF-α expression but not tumor promotion
Overexpressing PKCα in mice skin increases inflammation but doesn't affect tumor growth.
research Transient activation of β-catenin signalling in adult mouse epidermis is sufficient to induce new hair follicles but continuous activation is required to maintain hair follicle tumours
Temporary activation of β-catenin can create new hair follicles, but ongoing activation is needed to keep hair follicle tumors.
research Cellular Activity in the Dermis Surrounding the Hair Bulb in Alopecia Areata
Hair growth in alopecia areata is hindered due to impaired cell activity in the surrounding tissue.
research [Expressions and effects of autophagy-related genes in bleomycin-induced skin fibrosis of mice].
Activating autophagy might reverse skin fibrosis.
research Apoptosis and keratin intermediate filaments
research Human hair follicle stem cell differentiation into contractile smooth muscle cells is induced by transforming growth factor-β1 and platelet-derived growth factor BB
Human hair follicle stem cells can become smooth muscle cells using specific growth factors.
research Scanning Electrochemical Microscopy of Iontophoretic Transport in Hairless Mouse Skin. Analysis of the Relative Contributions of Diffusion, Migration, and Electroosmosis to Transport in Hair Follicles
Hair follicles significantly enhance electroosmotic transport during iontophoresis.
research Characterization of Primary Cilia and Intraflagellar Transport 20 in the Epidermis
Ift20 is essential for hair follicle function and skin cell movement.
research The protease corin regulates electrolyte homeostasis in eccrine sweat glands
Corin helps control salt and sweat release in sweat glands.
research Analysis of Gene Expression in Isolated Single Hair Follicles: An Approach Using Semiquantitative Reverse-Transcriptase—Polymerase Chain Reaction
Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.
research Comparison of minoxidil sulfotransferase activity between scalp hair, eyebrows, and eyelashes: Implication for minoxidil efficacy for off‐label use
Minoxidil is less effective on eyebrows and eyelashes than scalp hair because these areas have lower enzyme activity needed to activate the drug.
research Determination of rat 5α-reductase type 1 isozyme activity and its inhibition by novel steroidal oxazolines
New steroidal compounds moderately block an enzyme related to testosterone conversion, less effectively than finasteride.
research Expression Pattern of Cyclooxygenase-2 in Normal Rat Epidermis and Pilosebaceous Unit during Hair Cycle
COX-2 levels change during the hair cycle and affect skin and hair growth.
research Tenascin expression in normal human adult skin and skin appendage tumours
Tenascin is present in normal skin and certain skin tumors but not in sebaceous glands or their tumors.
