In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

Slug (Snai2) helps regulate hair growth timing in mice.

This study found that in bovine skin, leptin and its receptor are expressed in the epidermis and hair follicles, suggesting a role in epidermis growth and hair follicle cycling through paracrine and autocrine mechanisms.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

This study found that anthralin and mechlorethamine were the most effective therapies among those tested in AA-affected rodent models, providing a basis for further analysis of their mechanisms in Alopecia Areata.

This study introduced a new in vivo angiogenesis assay using Gelfoam implanted in ND-GFP transgenic mice to efficiently identify angiogenesis stimulators and inhibitors through GFP visualization.

This study found that the promoter region of the sheep KRTAP11-1 gene drives specific transcriptional activity in wool follicles, suggesting it may regulate hair keratinocyte specificity.

This study found that patients with active severe alopecia areata exhibited decreased CD200 expression on T and B lymphocytes, which may be linked to an imbalance in Th1/Th2 immune equilibrium.

This essay discusses the role of the nail in mammalian digit tip regeneration and explores whether nail stem cells are solely responsible for this regenerative ability, with no new results presented.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study demonstrated that keratin K124 is specific to equine hoof lamellar tissue and established monoclonal antibodies that can specifically recognize K124 without cross-reacting with other tissues.

This study concluded that the expression of clock genes, specifically BMAL1, in hair follicles is linked to circadian rhythm, and BMAL1 regulates hair growth.

This case report presents the first evidence of significant antigen presenting cells around hair follicles in a patient with alopecia due to active systemic lupus erythematosus.

This study found that exposure to 12-O-tetradecanoyl-phorbol-13-acetate in mouse skin caused changes in claudin expression and localization, indicating disruption and eventual recovery of the epidermal barrier.

In this study, researchers found that androgenetic alopecia is associated with increased gene expression related to inflammation, stress, and fibrosis, particularly affecting the hair follicle stem cells and showing similarities to diseases like psoriasis.

This study found that Sox9 was variably expressed in most canine skin neoplasms, particularly in those originating from the hair follicle's bulge region, suggesting its potential as a stem cell marker.

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 found that menopausal status and hormone therapy significantly affect the histology and gene expression of the introitus, with post-menopausal women showing notable tissue remodeling associated with vaginal atrophy.

This study investigated how keratinocytes in the skin respond to different iron levels and found they play a significant role in regulating iron homeostasis by storing iron, affecting epidermal differentiation, and influencing inflammation-related gene expression in mice.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

In this study, microarray and proteomic analyses indicated that genes involved in immune response, receptor binding, and growth factor activity might influence wool fibre diameter in sheep.

This article describes a method using the CUBIC protocol to clarify and visualize molecular and cellular interactions in mouse skin biopsies at single cell resolution, but does not provide new biological findings.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

This study suggests that inducible transgenic mice showing hair follicle changes similar to telogen effluvium in humans might serve as a useful model for understanding this type of hair loss.

This study found that platelet-rich fibrin lysates modulate chemokine expression, reducing inflammation in oral squamous carcinoma cells, but increasing expression in primary oral epithelial cells.

In this study, researchers developed a predictive model for the onset of alopecia areata by analyzing six datasets to identify key feature genes and employing various machine learning algorithms, ultimately finding the XGBoost model most effective for clinical application.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

In this study, researchers found that the SLICK1 allele in cattle may alter local immune regulation, hair growth, and tissue remodeling, as indicated by differential gene expression pathways associated with immune and inflammatory responses in slick vs. nonslick Holsteins.

This genome-wide association study identified several genetic markers, including specific SNPs and HLA genotypes, associated with alopecia areata susceptibility in the Taiwanese population, highlighting key pathways involved in immune response and offering insights into the genetic origins of this autoimmune condition.
