Research
60-90 / 1000+ resultsresearch Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
research Hair Keratins and Hair Follicle–Specific Epithelial Keratins
Hair and follicle keratins differ in structure and expression, especially in cysteine content.
research Regulation of hard α-keratin mechanics via control of intermediate filament hydration: matrix squeeze revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research Hair keratin pattern in human hair follicles grown in vitro
Human hair follicles grown in vitro maintain normal keratin patterns and structure.
research Identification of the Ovine Keratin-Associated Protein 26-1 Gene and Its Association with Variation in Wool Traits
Selecting specific KRTAP26-1 gene variants can improve wool quality in sheep.
research Immunohistochemical demonstration of keratins in the epidermal layers of the Malayan pangolin (Manis javanica), with remarks on the evolution of the integumental scale armour
Keratins in Malayan pangolins vary by region, suggesting scales evolved from the tail towards the head.
research Structural features and sites of expression of a new murine 65 kD and 48 kD hair-related keratin pair, associated with a special type of parakeratotic epithelial differentiation
A new pair of mouse keratins, 65 kD and 48 kD, are found in specific skin areas and are linked to a unique skin differentiation type.
research A Splice Site Mutation in the Gene of the Human Type I Hair Keratin hHa1 Results in the Expression of a Tailless Keratin Isoform
A genetic mutation in the hHa1 gene creates a smaller, but still functional, hair protein without causing hair problems.
research Expression patterns of hair and epithelial keratins and transcription factors HOXC13, LEF1, and β‐catenin in a malignant pilomatricoma: a histological and immunohistochemical study
The malignant pilomatricoma showed strong epithelial keratin expression, suggesting it may not calcify.
research Identification of somatic and germline mosaicism for a keratin 5 mutation in epidermolysis bullosa simplex in a family of which the proband was previously regarded as a sporadic case
The keratin 5 mutation in a family with epidermolysis bullosa simplex was due to mosaicism, not a new mutation.
research Monilethrix: a keratin hHb6 mutation is co‐dominant with variable expression
A keratin hHb6 mutation causes a hair disorder with varying severity, influenced by other factors.
research Comparative genomics analyses of alpha-keratins reveal insights into evolutionary adaptation of marine mammals
Marine mammals lost many α-keratin genes, aiding their adaptation to aquatic life by becoming hairless.
research Induction of Hard Keratin Expression in Non-Nail-Matrical Keratinocytes by Nail-Matrical Fibroblasts through Epithelial-Mesenchymal Interactions
Nail-matrical fibroblasts can make non-nail cells produce hard keratin, useful for nail repair.
research Nucleation and growth of macrofibrils in trichocyte (hard-α) keratins
Sheet formation is key to macrofibril structure differences in wool.
research Hair keratin KRT81 is expressed in normal and breast cancer cells and contributes to their invasiveness
The hair keratin gene KRT81 is found in both normal and breast cancer cells and helps them invade surrounding tissues.
research The Proteins of Normal and Aberrant Hair Keratins
Hair is mostly made of three protein types: helical, high-sulfur, and high-tyrosine.
research Structural changes in trichocyte keratin intermediate filaments during keratinization
Keratin structure changes during keratinization, but the exact model remains uncertain.
