This study identified a novel mutation and confirmed a previous mutation in the LIPH gene in a woman with autosomal recessive woolly hair, expanding the mutation spectrum for this condition.

This article reviews the role of LMNA gene mutations, particularly in Hutchinson–Gilford progeria syndrome, but does not report new experimental findings.

This study found two recurrent missense mutations in the hHb6 gene associated with monilethrix in families from Russia and Colombia, supporting their role in this hair disorder worldwide.

This study found that lipids are highly correlated with hair curvature while proteins are not, reporting the largest number of hair lipids and identifying novel proteins and chaperones relating to different hair types for the first time.

This article explores the potential applications of polyglutamic acid in cosmetics, discussing its benefits for skincare and haircare, but reports no new experimental results.

This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.

In this study, researchers conducted additional IHC staining on equine skin sections and found that collagen type III primarily labels the extracellular matrix, while anti-PDGFR-antibody staining highlights cells with long-shaped processes mainly arranged around hair follicles.

This study found that a unique transglutaminase in guinea pig hair-follicles, distinct from liver transglutaminase, likely plays a role in forming protein cross-links via ε(γ-glutamyl)lysine bonds.

This study found that acid regulation of the TRPV3 channel can inhibit its function from outside the cell while facilitating it from inside, providing insights into skin barrier and disorder mechanisms related to tissue acidosis.

In this study, the RADA-PRG hydrogel enhanced SKP proliferation, survival, and gene expression, effectively supporting hair follicle regeneration in mice.

This review discusses the molecular pathology of progeroid syndromes and reports no new results; the authors emphasize understanding these mechanisms to develop treatments and potentially improve quality of life for affected individuals.

This study found that COL17 deficiency in neonatal mice causes abnormal skin cell proliferation due to disrupted Wnt signaling, while replenishing or overexpressing COL17 can reverse this effect in both neonatal and aged skin.

In this study, researchers identified novel LMNA mutations in patients with atypical progeroid syndrome, revealing clinical features distinct from other similar disorders, but unrelated to mutant prelamin A accumulation.

This study found that the peptides RMYYY and VMYMI displayed stronger binding energy and more frequent interactions with HPGDS compared to the native inhibitor, suggesting potential as future therapeutic drugs.

This study found that improved protein extraction methods enhanced the resolution of hair proteins on gels, but differences in protein abundance between curly and straight Japanese women’s hair were minimal and unlikely to affect hair structure.

This study developed a rapid method to extract proteins from human hair, revealing phosphorylation on serine and threonine residues in alpha-keratins and matrix proteins.

This study developed a reliable RP-HPLC-DAD method, finding that amino acid concentrations in bleached hair decrease with higher hydrogen peroxide levels, notably affecting cystine.

This case study reports that a heterozygous missense GJA1 mutation, p.Gly138Ser, in a 2-year-old boy with oculodentodigital syndrome primarily resulted in syndactyly, fifth finger hypoplasia, and hypotrichosis, without neurological or craniofacial abnormalities.

This study demonstrated that a newly developed polypeptide-protein hydrogel with vascularization and antibacterial properties promoted tissue regeneration and hair follicle formation in infected wound healing.

This study identified a specific LIPH gene mutation (736T>A) as common in Japanese patients with autosomal recessive woolly hair/hypotrichosis, potentially indicating its role in the condition's manifestation within this population.

This study investigated the effects of a recombinant human collagen complex on hair growth, finding it enhanced survival and function of hair follicle stem cells and promoted hair growth in rat models, suggesting its potential for hair loss prevention and hair health maintenance.

This study found that a PGE2 matrix, when injected subcutaneously, increased the proportion of developing hair follicles and improved hair follicle stem cell markers in a mouse model of hair loss.

This study suggests that the amino acid composition of fibrous proteins in normal human hair is similar to that of stratum corneum proteins, particularly in cysteine and glycine content.

This chapter reviews Hutchinson–Gilford progeria syndrome as a model for studying aging but presents no new findings, covering its genetic basis, clinical features, and existing treatments.

This study found that Hairless (HR) and putrescine form a negative regulatory network that impacts epidermal homeostasis and hair follicle cycling, linked to the MYC superfamily's regulation of ODC expression.

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 reported that atelocollagen enhances collagen synthesis and reduces oxidative stress in aged skin by increasing glycine uptake through GlyT1, resulting in improved skin elasticity and collagen density in aged mice, with effects superior to glycine alone.

This study found that mutations in exon 3 of the hr gene are strongly associated with congenital hypotrichosis in Valle del Belice sheep, suggesting a potential genetic link to the disorder.

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.
