This review examines current understanding of hair graying and suggests it may be caused by depletion of melanocyte stem cells due to genotoxic stress or dysfunctional melanocytes from oxidative stress.

This study identified key mRNAs and lncRNAs, along with related pathways, that play potentially important roles in hair follicle development and cycling in cashmere goats.

This review discusses advances in molecular biology and genetics related to androgenetic alopecia and reports no new clinical results.

This study developed a method for extracting proteins from micro-sized human head hairs, facilitating proteomic analysis even with limited hair sample availability.

This study found that overexpression of the FA2H gene in cashmere goats' hair follicle cells may enhance hair proliferation and regulate genes affecting cashmere fineness.

This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

This study found that specific genetic changes in both coding and noncoding regions may have independently driven the evolution of hairlessness in various mammalian species through accelerated evolution.

This study identified key genes involved in hair follicle development in Merino sheep, offering insights for improving wool production and providing a basis for future breeding programs.

This study found that Lymphotoxin-beta primarily influences periderm differentiation, impacting epidermal and hair follicle differentiation at later stages.

This study analyzed RNA-seq data from various animal breeds and suggested that similar molecular mechanisms may underlie wool fineness in different sheep breeds. Researchers identified 32 candidate genes related to hair follicle regulation, providing insights for molecular breeding and evolutionary studies.

This review explores epidermolysis bullosa simplex subtypes caused by mutations in KRT5 or KRT14 and summarizes gene expression patterns and molecular mechanisms, without presenting new experimental results.

This study reveals that long non-coding RNAs influence cashmere fiber traits in goats by interacting with target genes involved in pathways affecting fiber diameter and color.

This study examined gene expression in cashmere goats and identified key pathways and molecular regulators that influence hair follicle growth stages and melatonin's role in promoting cashmere growth.

KAP9.2 and Hoxc13 genes are important for cashmere growth and vary in activity during different stages.

In this study, collagen scaffolds functionalized with heparin and growth factors significantly enhanced long-term skin regeneration and growth in a sheep model of fetal skin defect, suggesting potential for prenatal spina bifida treatment.

The researchers reported that autophagy, a lysosome-dependent degradation mechanism, plays a significant role in the cellular remodeling of keratinocyte differentiation in the skin, affecting the properties of the differentiation products by altering cellular components during this process.

In this study, researchers identified ten key genes involved in the periodic development of hair follicles in cashmere goats, highlighting the importance of the Wnt signaling pathway and cell cycle in this process.

This study found that Hetian sheep with higher wool density produce more and finer wool, with key genes potentially influencing their wool growth and density.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

This study shows that NIPP1 deficiency in mouse epidermis leads to hyperproliferation, hair loss, and chronic skin inflammation, which can be partially alleviated by dexamethasone treatment.

This study found that Tibetan cashmere goats have genetic adaptations that contribute to their finer cashmere, possibly enhancing their ability to withstand the cold climate of the Tibetan plateau, while identifying specific genes related to hair growth, pigmentation, and heart development.

In this study, researchers found that specific miRNAs may regulate cashmere fiber traits in goats by targeting genes related to hair follicle activities, with significant expression differences between breeds.

In Angora rabbits, overexpression of miR-129-5p was found to induce apoptosis and inhibit proliferation of dermal papilla cells, highlighting its role in hair follicle development by targeting HOXC13.

Among Merino × Southdown cross sheep, this study found that certain variants of the KRT81 gene were associated with differences in fleece weight, but not with staple length or fibre diameter traits.

In this proteomic analysis, the researchers found that transitioning from crimped to straight wool in Tan sheep is linked to significant changes in wool protein expression, revealing distinct patterns of keratins and keratin-associated proteins that could influence wool quality and economic value.

This review discusses the patterns and regulatory mechanisms of keratin expression in various biological conditions and reports no new experimental results.

In this study, fingertip regeneration in mice was associated with specific signaling pathways involving hair follicles and hedgehog signaling, with potential implications for improving human hand injury treatments.

This review reports on the effects of aging on hair characteristics such as pigmentation, growth, and structural properties across genders and ethnicities, highlighting the importance of scalp health and suggesting cosmetic solutions to improve the appearance of aged hair.
