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 found that the AtSfh1 protein in Arabidopsis is essential for phosphatidylinositol-4,5-bisphosphate signaling crucial to polarized root hair growth, utilizing both phosphatidylinositol and phosphatidylcholine-binding activities.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

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 study found that peripheral clock genes, particularly BMAL1 and Period1, modulate human hair follicle cycling, suggesting their potential as therapeutic targets for affecting hair growth.

This study identified nine novel KRTAP5 family genes associated with human hair formation, demonstrating preferential expression in hair roots and suggesting their role in hair development.

In this study, two novel clusters of keratin-associated protein genes on human chromosome 11 were analyzed, suggesting their products are crucial for hair formation due to preferential expression in hair roots.

In this study, researchers identified two new keratin-associated proteins, hKAP1.6 and hKAP1.7, in human hair follicles, contributing to understanding hair fiber differentiation.

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 case report describes two patients with trichothiodystrophy who exhibited a different pattern of hair protein composition changes, suggesting a subgroup of TTD characterized by partial loss of high-sulfur proteins without significant alteration in their amino acid composition.

This study identifies two new proteins, CCDC22 and CCDC93, essential for root and root hair growth in Arabidopsis, and demonstrates their genetic link to a VTI13-dependent vacuolar trafficking pathway.

This study found that in Arabidopsis seedlings, tonoplast intrinsic proteins are targeted to the vacuole via at least two pathways, including pathways with differing sensitivity to a chemical inhibitor that affect root hair growth and PIN2 targeting.

This study optimized the extraction process for abomasum protein from Tianshan red deer, identifying two proteins with anti-inflammatory and anti-tumor activities, suggesting they could be beneficial in foods and nutraceuticals.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

This study found that hydrophilic carbon dots (Lys-CA-CDs) induced bovine serum albumin to form more wormlike fibrils, while inhibiting hen egg white lysozyme from forming hair-like fibrils.

This study found that GALT5 and GALT2 are redundant enzymes essential for O-glycosylation of AGPs, with mutations leading to significant growth and development defects in plants.

This study found that biostimulant application in lettuce cultivation led to significant yield and phytochemical enhancements, with effects varying between green and red cultivars depending on the treatment method used.

This study found that the molecular structures of α-keratin and collagen in a 2,100-year-old female cadaver's hair and tendon were preserved, while fibrous molecule aggregations were altered.

This study found that applying the highest dose of biostimulant improved the fresh yield, leaf area, and ACO2 of hydroponically grown ‘Genovese’ basil, suggesting enhanced productivity with reduced fertilizer use.

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.
