New mutations in hair keratin genes can change hair structure and cause monilethrix, with nail issues more common in certain gene mutations.

The research identified a gene in sheep important for wool quality, which could help improve wool traits.

HOXC13 is crucial for regulating hair keratin genes in hair follicles.

Calcium reduces involucrin in rat hair bulbs but doesn't affect filaggrin and Kdap.

Thyroid hormones affect hair follicle stem cells by promoting differentiation and reducing growth.

The KRTAP36-2 gene in sheep affects wool yield.

Reptiles have genes similar to hair proteins, suggesting hair's genetic origins predate mammals.

Recombinant collagen with nicotinamide boosts hair growth and health.

Human and bovine hair follicles have distinct cytokeratins specific to hair-forming cells.

Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.

Certain mutations in the PADI3 gene may increase the risk of developing a type of scarring hair loss common in women of African descent.

Human hair keratins were cataloged, showing their roles in hair differentiation stages.

Genetically modified sheep with more β-catenin grew more wool without changing the wool's length or thickness.

A new protein linked to hair strength was identified, aiding in understanding brittle hair conditions.

Electrical epilation damages hair follicles and surrounding skin, likely preventing hair regrowth.

Genes related to keratin, skin cell differentiation, and immune functions are key in hedgehog skin and spine development.

The study found that certain genes are important for hedgehog skin appendage development and immunity, with spines possibly evolving for protection and infection resistance.

Nestin is found in hair follicle progenitor cells, linking them to neural stem cells.

Nestin-expressing progenitor cells become outer root sheath keratinocytes.

IRS-specific genes in Tan sheep hair follicles peak at birth and may affect wool crimp.

The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.

Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.

Noggin promotes skin tumors by activating Wnt and Shh pathways.

Keratin from human hair helps nerves heal faster.

Rushton's hyaline bodies form from hair keratin and blood substances.

Keratin expression reflects cell organization and differentiation, not causes it.

Human hair keratins K85 and K35 create unique filament patterns important for early hair formation.

Keratin proteins are crucial for hair growth and structure.

The research found that people's hair proteins vary, especially by ethnicity and body part, which could help identify individuals in forensic science.

The research found that people's hair proteins vary by individual and body part, with some differences between ethnic groups, which could help in forensics.
