research Proteomic analysis of hair shaft and nail plate.
Hair and nail proteins, mainly keratins, are crucial for structure and can indicate health issues.
research Size Polymorphisms in the Human Ultrahigh Sulfur Hair Keratin-Associated Protein 4, KAP4, Gene Family
The study found that variations in hair protein genes are likely due to evolutionary deletions or duplications.
research A role for the Tgf-β/Bmp co-receptor Endoglin in the molecular oscillator that regulates the hair follicle cycle
Endoglin is crucial for proper hair growth cycles and stem cell activation in mice.
research Characterization of the proteins of guinea-pig hair and hair-follicle tissue
Guinea-pig hair and follicle proteins are mostly similar, but follicles have more group 2 proteins and fewer group 3 and 4 proteins.
research Hair and Nail Relationship
Hair and nails are similar keratin structures with different shapes and growth, affected by the same diseases and environmental factors.
research Study of seed hair growth in Populus tomentosa, an important character of female floral bud development
Poplar seed hairs grow from the placenta at the ovary base, with endoreduplication playing a key role in their development, and share similar cellulose synthesis processes with cotton fibers.
