This study found that subcutaneous adipose tissue-derived extracellular vesicles (AT-EVs) protect skin from photodamage by enhancing fibroblast proliferation and reducing oxidative stress compared to those from adipose-derived stem cells.

This study found that one month of diabetes altered neuroactive steroid levels and associated mechanisms in the hippocampus and cerebral cortex of an experimental rat model.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

An elderly man with skin amyloidosis and abnormal blood proteins was monitored without finding widespread disease after 18 months.

In this study, a specific SNP in the A2M gene of Murrah buffaloes was significantly associated with increased fat production and higher fat and protein percentages in milk.

This study suggests that the expression of VLCFA biosynthesis genes is suppressed in skin hyperplasia and cancer, which could influence keratinocyte function.

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.

In this study, Allium hookeri extract increased viability and size of dermal papilla cell spheroids and reduced oxidative stress effects, potentially promoting hair growth by regulating specific protein signaling pathways in human cells.

This study found that human trichohyalin has a unique protein sequence potentially contributing to at least three important functions in hair follicle and epidermal cells.

This study achieved successful cloning of the ovine keratin associated protein 6-1 gene, which may facilitate future research on transgenic animals and hair follicle gene regulation.

This study identified that the ND1 gene sequence of the Asian black bear's Sichuan subspecies shares high similarity with those of other bear species, raccoons, and Ailurus fulgens.

This study reports that a 190,000 molecular weight protein, identified as trichohyalin, may play a matrix role in the development of inner root sheaths in hair follicles.

This case report describes a rare instance where a child with nonketotic hyperglycinemia developed an acrodermatitis enteropathica-like eruption, likely due to combined zinc and branched chain amino acid deficiencies.

The researchers reported that PPARβ/δ may influence the yak hair follicle cycle by modulating lipid metabolism in dermal papilla cells, with varying expression during different hair growth phases, affecting both lipid content and cell proliferation.

This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.

This study found that an injectable hydrogel, SF-g-SDA, outperformed commercial Tegaderm™ in healing wounds, promoting collagen deposition, and enhancing neovascularization in animal models.

A woman's skin symptoms led to a diagnosis of systemic AL amyloidosis, but she died from sepsis shortly after.

This study found that the expression of laminin-511 and -332 was significantly increased in psoriasis skin lesions and may influence keratinocyte proliferation and apoptosis, suggesting a previously overlooked role in the disease's pathogenesis.

This study suggests that epidermal turnover could be a regulated mechanism of iron excretion, with systemic iron levels influencing keratinocyte behavior and differentiation markers in the skin.

This study found that EDA and EDAR are expressed throughout cashmere goat fetal development and play a critical role in hair follicle formation by influencing gene expression in fibroblasts and epithelial cells.

This study found that the expressions of CDK inhibitors p21waf1/cip1 and p27kip1 were higher during the anagen phase compared to telogen, suggesting a role in follicular epithelial cell differentiation.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

In this study, Sper-12/siRNA nanoparticles effectively suppressed abnormal AR protein levels, promoted hair follicle proliferation, and alleviated hair loss symptoms in androgenetic alopecia model mice, providing a promising delivery platform for siRNA-based therapeutics.

This book chapter discusses the mechanisms and prevention of selenium toxicity in livestock and reports no new experimental results; it emphasizes reducing selenium in the human food chain through animal products.

This review discusses the hierarchical structure and chemical properties of hair fibers and offers insights for chemists and biochemists, but reports no new experimental findings.

Keratin structure changes during keratinization, but the exact model remains uncertain.

This review discusses the diagnosis and management of acquired haemophilia and reports no new findings; the authors highlight the importance of early diagnosis to reduce mortality.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

This chapter reviews the chemistry of keratin fibers, which are essential for understanding the structural stability and functionality of mammalian hair and other similar biological materials.

The document concludes that significant investment in agricultural innovation is necessary to achieve global food security and nutrition.
