30 / 1000+ resultsresearch The Process of Cornification Evolved From the Initial Keratinization in the Epidermis and Epidermal Derivatives of Vertebrates: A New Synthesis and the Case of Sauropsids
Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.
research Perspectives on Hair Evolution Based on Some Comparative Studies on Vertebrate Cornification
Hair in mammals likely evolved from glandular structures, not scales.
research TRPV3 Ion Channel: From Gene to Pharmacology
The TRPV3 ion channel is important for skin and hair health and could be a target for treating skin conditions.
research Review: Evolution and diversification of corneous beta‐proteins, the characteristic epidermal proteins of reptiles and birds
Corneous beta-proteins evolved uniquely in reptiles and birds, forming scales, claws, beaks, and feathers.
research Reptile scale paradigm: Evo-Devo, pattern formation and regeneration
Reptile scales help us understand the evolution of skin features like hair and feathers.
research 5α-Reductase underscores the development of pectoral fin breeding tubercles in zebrafish
The development of breeding tubercles in male zebrafish relies on a specific enzyme that processes hormones.
research Morroniside regulates hair growth and cycle transition via activation of the Wnt/β-catenin signaling pathway
Morroniside may help hair grow and stay in its growth phase by affecting certain cell signals.
research Genomic and anatomical comparisons of skin support independent adaptation to life in water by cetaceans and hippos
research Comprehensive molecular and cellular studies suggest avian scutate scales are secondarily derived from feathers, and more distant from reptilian scales
Bird scales evolved from feathers, not reptile scales.
research Sarcoidosis in Polo Ponies: Case Study of Argentine-Cross Breeds
Argentine-cross polo ponies commonly develop sarcoid tumors with distinct types and histopathological features.
research Molecular and Cellular Characterization of Avian Reticulate Scales Implies the Evo–Devo Novelty of Skin Appendages in Foot Sole
Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.
research The Story of the Finest Armor: Developmental Aspects of Reptile Skin
Reptile skin protects and prevents water loss, helping them adapt to land.
research Fish Cell Spheroids, a Promising In Vitro Model to Mimic In Vivo Research: A Review
Fish cell spheroids are a promising tool for replicating real-life conditions in research.
research A new family of Acarines belonging to the suborder Sarcoptiformes parasitic in the hair follicles of Primates
Two new mite species were found in a monkey's hair follicles, leading to a new genus and family proposal.
research Terrestrial vertebrates have two keratin gene clusters; striking differences in teleost fish
Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.
research Extensive Ichthyosiform Sarcoidosis in a Patient With Juvenile Rheumatoid Arthritis
Systemic corticosteroids can cause unusual skin issues in people with juvenile rheumatoid arthritis.
research Evolution of hard proteins in the sauropsid integument in relation to the cornification of skin derivatives in amniotes
Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.
research Evo Devo of the Vertebrates Integument
The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.
research 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 remarks on the evolution of the integumental scale armour
Pangolin scales evolved for protection, hardening with age, due to keratin gene diversification.
research Cloning, computational analysis and expression profiling of steroid 5 alpha-reductase 1 (SRD5A1) gene during reproductive phases and ovatide stimulation in endangered catfish, Clarias magur
The research identified and described a gene important for hormone conversion in endangered catfish, which varies in activity during different reproductive stages and after hormone treatment.
research Skin Appendage Proteins of Tetrapods: Building Blocks of Claws, Feathers, Hair and Other Cornified Epithelial Structures
Understanding proteins in skin structures like claws and hair is crucial for future research.
research The regeneration of caudal epidermal specializations inLygodactylus picturatus keniensis (gekkonidae, Lacertilia)
Lizards can regrow their tail scales with the same structure, distribution, and gender-specific features as the original ones, and this unique ability is not seen in adult mammals.
research Structural and Immunocytochemical Characterization of Keratinization in Vertebrate Epidermis and Epidermal Derivatives
Vertebrate skin evolved to be more specialized and complex, especially in land animals.
research Cornified Epithelial Teeth of Jawless Vertebrates Contain Proteins Similar to Keratin-Associated Proteins of Mammalian Skin Appendages
Jawless vertebrates have teeth proteins similar to those in mammalian hair and nails.

Ichthyoses are skin disorders causing scales, with treatment depending on type and severity.
research Recent advances in neuropeptide-related omics and gene editing: Spotlight on NPY and somatostatin and their roles in growth and food intake of fish
New tools show that in fish, NPY increases feeding and somatostatin decreases it.
