research Ectodysplasin-A (EDA) Signaling Cross-Talk in Skeletogenesis
The EDA pathway plays a key role in bone development by interacting with other signaling pathways.
research Horn With Miliary Calcification in Squamous Cell Carcinoma
A unique case of skin cancer showed unusual calcification, possibly linked to calcium-binding proteins.
research remarks on the evolution of the integumental scale armour
Pangolin scales evolved for protection, hardening with age, due to keratin gene diversification.
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 A highly resistant structure between the cuticle and the cortex of human hair. II . CARB , a penetration barrier
CARB is a strong barrier in human hair that prevents dye penetration.

A rare calcium deposit condition was found on a man's scalp.
research Steatocystoma
research Epithelial barrier function: assembly and structural features of the cornified cell envelope
The cornified cell envelope forms a protective barrier in skin and hair, using specific proteins and lipids to maintain effectiveness.
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.
