This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

In this study, researchers found that follicular and epidermal transglutaminases are biochemically and immunologically distinct, suggesting the possibility of selectively modifying hair or epidermal proteins.

This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

In this study, nucleotide sequence variation in the KRTAP13-3 gene was associated with changes in heterotypic hair fibre diameter variation in Chinese Tan sheep.

PTHrP is important for bone formation and may be targeted for osteoporosis treatment and longevity therapies.

This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

This study concluded that the frizzy mutation in mice is linked to a T to A transversion in Prss8 and is orthologous to the 'hairless' mutation in rats.

This study suggests that keratin peptide signatures in human hair shafts may potentially be used to distinguish gender and ethnicity, although further validation with larger samples is needed.

This study found that high levels of parathyroid hormone-related protein expression can result in the production of shorter hair shafts, likely through effects on angiogenesis.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This study suggests that longer GGN repeat polymorphisms in the androgen receptor gene are associated with polycystic ovary syndrome in women.

This study demonstrated that injecting reconstructed dermal papilla-like tissues in mice led to new hair growth, suggesting potential future applications in hair transplantation and baldness treatment.

This study found that both marine and bovine collagen peptides may help prevent hair loss by supporting epithelial hair follicle stem cell functions, with marine peptides maintaining hair in the growth phase and bovine peptides increasing stem cell presence in hair follicle regions.

This study found that Prss53-mutated rabbits exhibited curved hair and skeletal dyskinesia, suggesting a link between Prss53 loss and these traits, potentially involving disrupted calcium metabolism.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

This research suggests that defects in keratinocyte differentiation due to putrescine accumulation in SSAT transgenic mice lead to skin changes and hair loss, and reducing putrescine can promote hair regrowth.

Balanced protease activity is crucial for healthy skin and hair development.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

In this study, researchers identified gremilin-2 as a highly specific gene to the dermal sheath cup, suggesting it plays a key role in maintaining its properties.

This study suggests that epithelial-derived pop-up keratinocytes (ePUKs) may improve regenerative medicine applications due to their specific phenotype and increased expression of proteins involved in regulating cellular movement and wound healing.

This study found that the hHa1-t protein variant, caused by a genetic polymorphism in the hHa1 gene, forms functional keratin filaments despite lacking a complete nonhelical tail domain, explaining the absence of a pathological hair phenotype.

This study found that as few as 90 base pairs of the K5 promoter directed keratinocyte-preferred expression in stratified epithelia, especially in epidermis, hair follicles, and tongue, showing cell type specificity.

Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.

This research investigated the role of EphA1 in embryonic and adult tissues, generating mouse models suggesting potential links to skin and colon cancer, sepsis, and post-traumatic injury.

This study identified a germline variant in PLCD1 as a major risk allele for familial trichilemmal cysts, requiring a subsequent somatic mutation in the same allele for cyst formation.

This study suggests that some keratin-associated proteins with antecedents found in non-haired animals may have roles beyond hair characteristics, possibly contributing to the evolution of hair follicles.

This study found that a new formulation kit of Pielus Anti-hair loss lotion and shampoo, used daily for 90 days, was safe and effective in reducing hair loss and increasing hair strength and density among patients with telogen effluvium and/or androgenetic alopecia.

This study found that certain off-label topical therapies, including prostaglandin analogs and polyphenols, improved hair restoration in men with androgenetic alopecia over placebo in the short term, though long-term effects are unknown.
