This study found that KRTAP2 proteins predominantly express in the hair shaft cortex of humans, interact with hair keratins, and play crucial roles in hair shaft keratinization.

In this study, cisplatin was found to induce cell death in human hair follicle cells through hydroxyl radical generation and Bcl-2 down-regulation, suggesting potential strategies for preventing chemotherapy-induced alopecia.

Injecting lentiviral vectors into early gestation mice effectively targets skin stem cells for potential gene therapy.

This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

This study identified two key pentapeptide quasi-repeats in human keratin-associated proteins, which are similar to motifs found in sheep wool.

In this study, chemical treatments during permanent hair straightening were found to randomize proteins in the cortex, aiding in the reconnection of disulfide bonds during oxidation.

This study found that monoclonal antibodies can identify specific immunological characteristics of hair fibrous proteins, with some antibodies reacting only with hair proteins and others showing broader activity with skin and epithelial cells.

This study suggests that activating retinoic acid signalling can inhibit Wnt signalling and induce regression in certain skin tumors, providing potential therapeutic strategies for tumor regression.

This study found that disulfide bonds in keratin increase its strength and toughness, with some loss of α-helical structure under load, highlighting their role in trichocyte α-keratin's mechanical properties.

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

This study reports that AS101 induced hair growth in mice and suggests potential for treating chemotherapy-induced alopecia in humans, which was observed in case report studies with three adolescents.

A mutation in the KRT25 gene causes a rare hair disorder with thin, woolly hair.

In this study, the combination of keratin-gelatin from poultry feathers promoted early acceptance and viability of full-thickness skin mesh grafts in experimental dogs compared to other treatments.

This study details how very long human hair naturally ages, showing cuticle wear and internal fiber changes that may inform new hair care product designs.

This study found that only eumenorrheic polycystic ovary syndrome patients showed a temporal coupling between kisspeptin and luteinizing hormone pulsatile secretions.

This study found that 1,25-dihydroxyvitamin D3/VDR inhibits β-catenin's role in keratinocyte proliferation but enhances its role in hair follicle differentiation.

This study found that careful light microscopy using fluid-mounted hair improves detection of the pili annulati phenotype, which varies widely in expression and affects hair fragility.

In this study, minoxidil sulfate was found to relax norepinephrine-induced contractions in rabbit mesenteric arteries, possibly by acting as a K+ channel agonist, but it did not relax K+-induced contractions.

This study found that curcumin encapsulated in liposomes enhanced photodynamic therapy's effectiveness against skin cancer cells while reducing toxicity to normal human keratinocytes.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

This study found that although progerin expression in mouse skin causes significant nuclear shape changes in keratinocytes, it does not result in alopecia or common skin abnormalities seen in human Hutchinson–Gilford progeria syndrome.

In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

This study found that dimethylarsinic acid significantly accelerates skin tumor development in hair follicle-targeted K6/ODC transgenic mice.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

The researchers reported that stress-induced keratins in human skin are expressed at lower levels than those in healthy skin and are co-regulated with genes involved in differentiation, inflammation, and immunity, rather than replacing keratins of normal differentiation or indicating cell proliferation.

Keratin peptides can change hair shape gently without harsh chemicals.

This study observed that increasing the γ-kerateine content in meta-kerateine materials led to reduced elasticity, solidity, and hydrolytic stability, and decreased hepatocyte attachment support.
