The K15 promoter effectively targets stem cells in the hair follicle bulge.

This review discusses the role of corticotropin-releasing hormone in human skin, focusing on its regulation, receptors, and functions, and highlights parallels with the hypothalamo-pituitary-adrenal axis; it reports no new research findings.

This study highlights the complex role of the vitamin D receptor in skin processes, where its disruption, along with calcium and co-regulator imbalances, could contribute to skin cancer development by altering skin differentiation and hair follicle cycling.

This study found that heterozygous mice overexpressing Claudin-6 experienced alterations in epidermal and hair follicle differentiation, leading to distinctive coat characteristics and a disrupted epidermal permeability barrier.

This study found that circadian clock genes are involved in regulating the hair growth cycle, suggesting a connection between daily rhythms and the longer hair follicle cycling process.

This study identified key genes and miRNAs involved in feather morphogenesis in Zhedong White geese, highlighting a negative correlation between FOXO3 and miR-144-y.

This study identified a new cytokeratin, mK6irs, specifically expressed in the inner root sheath of mouse hair follicles, distinguishing it as a member of the type II cytokeratin family.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study found that Runx3 deficiency in mice affects hair type and shape, suggesting it may regulate hair formation through interactions between dermal and epidermal layers.

This study found that ocu-miR-205 influences hair follicle density and signaling pathways in Rex rabbits by promoting dermal papilla cell apoptosis and altering hair follicle phases.

This study found that ICAM-1 expression in murine skin is developmentally regulated and crucial for skin and hair follicle remodeling beyond its recognized role in immune responses.

This study found that genes encoding mouse high-glycine/tyrosine proteins show distinct spatial and temporal expression patterns in hair follicles, suggesting diverse protein distribution during hair growth cycles.

This study observed that nutritional stress is likely responsible for changes in Merino sheep follicle morphology in Mediterranean environments, affecting staple strength and possibly requiring targeted management strategies.

In this study, researchers found that the FoxN1, FoxE1, and FoxI3 genes are likely involved in hair follicle growth and development in cashmere goat fetuses.

This review provides a comprehensive overview of apoptosis-related molecules in head development, highlighting caspases' roles and associated abnormalities in tissues like the brain, sensory organs, skin, and bones, without reporting new results.

This study found that EGR1 promotes the proliferation of dermal papilla cells, suggesting its close association with hair follicle growth and development.

This study reports that bilateral adrenalectomy and DOC treatment in mink significantly advanced the onset of summer fur growth compared to controls, indicating adrenal hormones may inhibit this process.

In this study, researchers investigated a regulatory network in cashmere goat embryos and found that fibroblast growth factor 10, alongside non-coding RNAs, significantly influences hair follicle cell proliferation, offering insights into the biology of hair follicles in cashmere goats.

This study identified a gene variant in the TRPV3 gene that may explain the suri alpaca phenotype, characterized by longer and less crimped fleece, suggesting this variant's involvement in the development of these hair characteristics compared to the huacaya phenotype.

This study introduces the concept of a "gut–brain–skin axis" where ingesting a specific Lactobacillus strain in mice may reduce stress-induced skin inflammation and hair growth inhibition.

This manuscript reviews the latest understanding of alopecia areata's pathogenesis, highlighting the roles of genetic, immunological, and environmental factors, with a focus on immune responses involving IFN-γ and cytotoxic CD8+ T-cells as key contributors to hair follicle inflammation and function disruption without follicle destruction.

This article reviews the pattern and progression of androgenic alopecia in men and women, but it does not present new clinical findings.

This study indicates that sheep prenatally androgenized with testosterone show wool fiber diameter changes that parallel the increased hair diameter in women with polycystic ovary syndrome.

Hair growth is cyclic and influenced mainly by local factors.

This study found that loss of the ACER1 gene in mice led to increased ceramide levels and progressive hair loss, highlighting ACER1's role in maintaining hair follicle stem cell homeostasis.

This study suggests that PDGFA and BMP2 play a role in the hair follicle cycle in cashmere goats, with PDGFA particularly involved in activating the growth phase.

This study in mutant mice found that Bmpr2 and Acvr2a are individually redundant, but together essential for normal hair follicle development, with their reduction causing rapid hair cycling and graying.

This review highlights that microRNAs (miRNAs) play crucial roles in hair follicle development and cycling in cashmere goats, detailing recent advances in understanding their regulatory functions and potential applications in improving cashmere fiber quality and diagnosing hair disorders.

This study found that JUNB enhances hair regeneration in mice by promoting dermal papilla cell proliferation through the Wnt signaling pathway, suggesting JUNB as a potential molecular target for improving cashmere quality and breeding in cashmere goats.
