This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.

This study identifies six novel keratin genes from the chromosome 17q21.2 region, suggesting their association with hair follicles, while all 27 keratin genes in the domain have been characterized transcriptionally.

This study identified genes potentially involved in the development and differentiation of skin appendages in Atelerix albiventris, noting significant enrichment of immune-related genes in hair-type tissues.

In this study, researchers found that the cashmere hair growth cycle is divided into three periods and key genes like KAP and KRTAP are positively correlated with these cycles in cashmere goats.

This study provides evidence supporting a regulatory relationship between the transcriptional regulator Hoxc13 and Krtap16 genes, which are crucial for proper hair growth in mice.

This study identified a new ovine KRTAP21-1 gene variant in sheep, with wool yield affected by the variant, suggesting its potential as a genetic marker for improving wool production.

This article proposes an updated naming system for keratin-associated proteins and genes, aiming to improve data storage and retrieval by including species information and genetic variation.

This study found that polymorphisms in the KAP8.1 gene were significantly associated with cashmere weight, length, and guard hair length in Chinese Inner Mongolian Cashmere goats, but not with fibre diameter.

This study found that the promoter region of the sheep KRTAP11-1 gene drives specific transcriptional activity in wool follicles, suggesting it may regulate hair keratinocyte specificity.

In this study, the identification of a novel KAP gene in sheep, named KRTAP36-1, was associated with increased prickle factor in wool, suggesting its potential as a genetic marker for breeding purposes.

This study found that melatonin at 0.2 g/L for 72 hours most effectively enhances cashmere growth in Liaoning cashmere goats by upregulating the lncRNA MTC, which activates NF-kB signaling.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This review summarizes the anatomical and physiological aspects of human hair and its clinical significance, but does not report new research findings.

This study observed that the growth cycle of cashmere in Inner Mongolian cashmere goats consists of three phases, with genes KAP3–1, KRTAP 8–1, and KRTAP 24–1 closely correlating with this cycle.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

This study revealed that human keratin-associated protein genes are expressed in specific patterns in hair fiber regions and vary in size, with some variations distinct across different populations.
