This study reported that recombinant human hair keratins, K37 and K81, showed higher purity and enhanced fibrin clot formation compared to traditional extracts, reducing bleeding time and blood loss in rat injury models.

In this study, researchers found that autophagy is crucial for maintaining the mature protein composition of hair shafts, with its disruption leading to increased levels of various proteins, suggesting potential diagnostic applications for detecting impaired autophagy through hair proteomic analysis.

This study found that genetic variants in the goat KRTAP22-2 gene are associated with the mean fiber diameter of cashmere in Longdong Cashmere goats, suggesting these variants could serve as molecular markers for improving cashmere traits.

Keratin-based hydrogels from human hair improve wound healing effectively.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

In this study, researchers identified five unique sequences of the ovine KAP13-3 gene, with potential implications for wool traits due to observed amino acid changes.

In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

KAP8.1 protein is crucial for hair structure and interacts with keratin 85.

In this study, researchers developed a simplified and reliable method to prepare human hair shaft samples, achieving over 75% protein extraction efficiency and improved keratin sequence coverage, with the approach showing high reproducibility across different labs and operators.
