research Proteomic tools for the investigation of human hair structural proteins and evidence of weakness sites on hair keratin coil segments
Hair proteins have weak spots in their α-helical segments.
research Facial Hair Restoration
Facial hair restoration is generally successful and satisfying for patients when done with quality techniques and realistic expectations.
research Body composition changes and inhibition of fat development in vivo implicates androgen in regulation of stem cell lineage allocation
Androgen is important in controlling stem cell differentiation, reducing fat development, and increasing lean mass.
research Hair problems in women
Hair problems are common and distressing for women, but increasing knowledge of treatments offers hope.
research Studying SARS-CoV-2 infectivity and therapeutic responses with complex organoids
Organoids can help study COVID-19 and develop treatments, but face challenges like instability and limited renewal.
research Convergent Evolution of Cysteine-Rich Keratins in Hard Skin Appendages of Terrestrial Vertebrates
Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.
research Increased lactate dehydrogenase activity is dispensable in squamous carcinoma cells of origin
High lactate dehydrogenase activity is not necessary for the growth of squamous cell carcinoma.
research Dietary glucoraphanin prevents the onset of psychosis in the adult offspring after maternal immune activation
Eating glucoraphanin can help prevent psychosis in offspring whose mothers had immune system activation.
research Periorbital facial rejuvenation; applied anatomy and pre-operative assessment
Good preoperative assessment is crucial for safe and effective eyelid and brow cosmetic surgery.
research Madarosis: A marker of many Maladies
Losing eyelashes or eyebrows can be a sign of many different health problems and needs a careful approach to treat effectively.
research Human TSC2-null fibroblast-like cells induce hair follicle neogenesis and hamartoma morphogenesis
Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.
research Mapping the molecular and structural specialization of the skin basement membrane for inter-tissue interactions
The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.
research Systematic Analysis of Non-coding RNAs Involved in the Angora Rabbit (Oryctolagus cuniculus) Hair Follicle Cycle by RNA Sequencing
Non-coding RNAs play key roles in the hair growth cycle of Angora rabbits.
research CD98hc (SLC3A2) regulation of skin homeostasis wanes with age
CD98hc's role in skin health decreases with age.
research Over-expression of thymosin beta4 promotes abnormal tooth development and stimulation of hair growth
Too much thymosin beta4 causes weird teeth and more hair growth in mice.
research Graded levels of pyridoxine in the rat diet during gestation and the physical and neuromotor development of offspring
Not enough vitamin B6 in pregnant rats' diets caused poor development and health in their babies.
research STIMULATING EFFECT OF ADRENALECTOMY ON HAIR GROWTH AND MELANIN DEPOSITION IN BLACK RATS FED DIETS ADEQUATE AND DEFICIENT IN THE FILTRATE FACTORS OF VITAMIN B1
Adrenalectomy boosts hair growth and melanin in black rats, even with vitamin B¹ deficiency.
research Prognosis and Management of Congenital Hair Shaft Disorders with Fragility—Part I
Some congenital hair disorders improve in childhood or with treatments like minoxidil and retinoids, while others like Netherton syndrome and trichothiodystrophy have a poor prognosis.
research Oncogenic senescence: a multi-functional perspective
Cellular senescence has both cancer-blocking and cancer-promoting effects, and targeting senescent cells may improve health and lifespan.
research Characterization and Chromosomal Localization of Human Hair-Specific Keratin Genes and Comparative Expression During the Hair Growth Cycle
Two specific hair keratin genes are active during hair growth and decline as hair transitions to rest.
research Characterization of X-Linked SNP genotypic variation in globally distributed human populations
The research concluded that selection significantly shaped the genetic variation of the X chromosome, with certain regions affected by past selective events.
research Foot shock stress prolongs the telogen stage of the spontaneous hair cycle in a non‐depilated mouse model
Stress in mice delays hair growth and treatments blocking substance P can partly reverse this effect.
research Glucocorticoid Receptor Mutants Demonstrate Increased Motility Inside the Nucleus of Living Cells: Time of Fluorescence Recovery After Photobleaching (FRAP) Is an Integrated Measure of Receptor Function
Certain defective glucocorticoid receptor mutants move faster inside cell nuclei and work less effectively.
research miR-22 promotes stem cell traits via activating Wnt/β-catenin signaling in cutaneous squamous cell carcinoma
miR-22 helps skin cancer grow and spread by activating specific cell signals.
research Structure of human steroid 5α-reductase 2 with the anti-androgen drug finasteride
Finasteride irreversibly affects human steroid 5α-reductase 2, providing insight into its catalytic mechanism and disease-related mutations.
research Alopecia areata patients show deficiency of FOXP3+CD39+ T regulatory cells and clonotypic restriction of Treg TCRβ-chain, which highlights the immunopathological aspect of the disease
Patients with Alopecia areata have fewer specific immune cells that normally regulate the immune system, which may contribute to the condition.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Ectodysplasin research—Where to next?
Future research on ectodysplasin should explore its role in diseases, stem cells, and evolution, and continue developing treatments for genetic disorders like hypohidrotic ectodermal dysplasia.
