This study developed a biobased copolymer called SELP::KP, showing improved hair strength, elasticity, and conditioning properties while being a safer alternative to conventional chemical treatments, based on application to human hair in a laboratory setting.

In this study, keratin genes mHa1 and mHb4 were unable to form an extensive keratin network in one cell line, altering endogenous keratin distribution, but showed better integration in another cell line.

This review discusses the regenerative potential of polynucleotides and polydeoxyribonucleotides in aesthetic medicine, noting their benefits for skin texture, hydration, and patient satisfaction despite limited high-quality evidence.

This study found that early treatment with αCT1 in wound healing increased collagen synthesis and disorganization, potentially improving long-term scar appearance by altering early collagen matrix formation.

This review discusses how recent advancements in computational and lab-based methods have enhanced peptide drug discovery, noting the efficiency and cost benefits over traditional approaches and the potential for targeting difficult protein interactions, including protein degradation using proteolysis-targeting chimeras.

This issue information abstract introduces a collection of articles, including one on hair keratins' unique filament formation, without reporting new experimental findings itself.

This study suggests that while PTH rP initially seemed to shorten the hair cycle by transitioning hair follicles from anagen to catagen, more relevant models indicate it ultimately accelerates and stimulates hair growth.

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.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.

In this study, researchers purified and cloned rat peptidylarginine deiminase type III, demonstrating its activity and specific expression in the epidermis and hair follicles.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

This review examines genetic variation in the ovine KRTAP1.1 gene and its potential impact on wool quality, reporting no new findings but suggesting opportunities for developing gene markers for wool and pelt traits.

FOL-005 peptide may help treat excessive hair growth safely.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This study found that the N-terminal fragment of AIMP1 enhances hair growth and proliferation of hair follicle stem cells in mice, suggesting its potential as a therapeutic peptide for hair loss treatment.

This review compares DNA-derived biopolymers, PN and PDRN, in dermatology, emphasizing their distinct molecular characteristics and roles, and reports no new clinical results.

The research identified six functional hair keratin genes and four pseudogenes, providing insights into hair formation and gene organization.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This study found that a topical cream containing PTH (7–34) significantly stimulated hair growth in hairless mice.

This review discusses the complexity and genetic organization of human keratin gene clusters and addresses the ongoing need for an updated unified naming system; it reports no new clinical results.

This study identified a domain on human chromosome 21q22.1 containing various high glycine-tyrosine and high sulfur keratin-associated protein genes, revealing their diverse expression in hair-forming cells.

Matriptase is crucial for skin barrier, hair growth, and may contribute to skin cancer.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.

This study demonstrates that (9+2) topological patterns derived from fractal fiber sets exist, with nine total patterns and only two being independent or fundamental.

This study developed BroadAMP-GPT, a computational-experimental framework, to discover new antimicrobial peptides, identifying candidates effective against multidrug-resistant pathogens. Notably, AMP_S13 showed strong stability, low toxicity, and efficacy in infection models, highlighting the platform's potential in combating antimicrobial resistance.
