In this study, the researchers reported that a newly developed PYGL inhibitor, HTPI, enhanced hair growth in an ex-vivo culture by reducing oxidative damage in hDPCs and inhibiting glycogen degradation in hORSCs, showing potential as a treatment for hair loss comparable to minoxidil.

This study created transgenic mouse models with the LMNA gene mutation common in Hutchinson-Gilford progeria syndrome, revealing skin and teeth abnormalities related to transgene expression levels.

A specific mutation in PA-PLA1α causes abnormal hair growth.

This study suggests that disruptions in the Ran system related to nuclear transport may be a key factor in the development of cellular issues in Hutchinson Gilford Progeria Syndrome.

This study reports that Ca 2+ binding alters the dynamics and surface properties of PKD-like domains in Clostridium histolyticum collagenases, enhancing their stability and potentially aiding in collagen-targeting vehicle development.

This review discusses the history, structure, and biological significance of keratins, including the crystal structure of a keratin helical segment, without reporting new experimental results.

New mutations in hair keratin genes cause the rare hair disorder monilethrix.

This study concluded that specific SNPs in the TRPS1 gene significantly alter its protein structure, affecting interactions and contributing to the development of congenital hypertrichosis.

This study found that the mammalian Hr protein can interact with the p53 pathway by binding to a specific p53 response element, influencing the regulation of genes involved in cell cycle control.

This study reported discovering a novel missense variant in a case of autosomal recessive woolly hair in a 31-year-old Chinese woman, which significantly reduced secretion of the encoded protein, likely leading to disease by impairing its hydrolytic function.

This study found that human trichohyalin has a unique protein sequence potentially contributing to at least three important functions in hair follicle and epidermal cells.

In this study, PP-PTKL exhibited antioxidant, anti-inflammatory, and pro-melanogenic effects in laboratory settings, suggesting its potential role in preventing or treating hair greying. Further animal and human studies are needed to verify these findings.

Hair follicles have unique proteins that vary by species and are influenced by nutrition.

This study suggests that increased amounts of less stable disulfide conformers in hair shafts may be linked to the brittleness observed in trichothiodystrophy.

This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.

This study suggests that human trichohyalin may function as a flexible rod linking keratin intermediate filaments and as a scaffold protein in hair follicle and epidermis cell envelopes.

The hair follicle's connective tissue is a key source of a certain collagen in human scalp skin.

This study found that the penta-peptide Gly-Pro-Ile-Gly-Ser increased the proportion of thick hair and improved baldness appearance in Japanese men with androgenetic alopecia.

This study investigated the effects of 10600nm CO2 dot laser and Nd: YAG laser on Wistar rats' skin, finding that CO2 laser treatment resulted in higher positive expression of MMP-1 and TIMP-1 compared to Nd: YAG laser, with statistically significant differences noted.

This study identified a novel heterozygous missense mutation in the hHb3 gene associated with monilethrix, highlighting its role in this hair disorder.

This study found that genes encoding mouse high-glycine/tyrosine proteins show distinct spatial and temporal expression patterns in hair follicles, suggesting diverse protein distribution during hair growth cycles.

This study suggests that low molecular weight fish collagen peptide may promote hair follicle growth and regeneration, improving overall hair quality in mouse models.

This study compared hydrolysed wheat protein, L-arginine, and hydrolysed collagen for their effectiveness in enhancing the tensile strength of heavily bleached hair.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

In this in silico study, researchers analyzed nonsynonymous SNPs in the LIPH gene linked to hypotrichosis and identified three potentially harmful variants (W108R, C246S, and H248N) out of 215 total, using sequence- and architecture-based bioinformatics techniques to differentiate between harmful and benign SNPs.
