This study revealed that heterozygous mice with the hairy ear mutation exhibited significant gene expression changes related to hair growth, such as upregulation of hair keratin and keratin-associated proteins, shedding light on the Hoxc gene cluster's role in this phenotype.

In this study, researchers assessed cortisol levels in wolves by comparing hair and fecal samples and found a significant correlation, indicating that hair cortisol accurately reflects systemic levels, but season and body region affect results.

Alpha-MSH affects mitochondrial function, and MC1R mutations may increase skin aging.

In this study, researchers characterized the retinal structure and function of the Oat^rhg mouse model of gyrate atrophy, finding localized atrophy without significant retina-wide functional impact, suggesting the model may be useful for testing new treatments using multimodal retinal imaging.

In this study on Arabidopsis, the researchers identified CIPK13 and CIPK18 as crucial genes for root hair growth, finding that deficiencies in these genes resulted in shorter root hairs and reduced growth rates due to altered calcium oscillations.

In a study conducted on mice, researchers observed that exposure to ionizing radiation led to significant metabolic imbalances, including dyslipidemia and disruptions in amino acid metabolism, with activated protein C providing partial protection by normalizing certain plasma metabolites and lipids.

This study is the first to report major spontaneous diseases in aging Julia Creek dunnarts, highlighting hormonal dysregulation and lymphoid neoplasia as common conditions in this endangered species.

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 found that in mouse pancreatic β-cells, the disruption of keratin filaments due to a specific mutation in keratin 18 resulted in altered GLUT2 localization, with less GLUT2 present on the plasma membrane compared to cells with normal keratin.

This study showed that the zinc finger protein GIS3 is important for root hair growth in Arabidopsis by regulating RHD2 and RHD4 genes, with application of ethylene and cytokinin helping restore root hair presence in mutated variants.

This article reviews the use of hair cortisol concentration as a biomarker to assess long-term stress in both animals and humans, but it reports no new experimental results.

This study found that mitochondrial dysfunction in the epidermis contributes to aging-related changes in hair follicles among mice, with aged mice showing reduced hair density and delayed regrowth, suggesting that maintaining mitochondrial function may help prevent age-related organ decline.

In this study, 25% of CCHCR1-deficient mice exposed to stress developed hair loss similar to human alopecia areata, suggesting CCHCR1 is a susceptibility gene for the disease.

This study found that spatial transcriptomics can reveal hidden inflammation patterns in atopic dermatitis by correlating epidermal and dermal gene expression levels, improving understanding of skin pathology.

In this study, the authors identified a role for hair follicles in regulating the formation and sympathetic innervation of arrector pili muscles, influencing hair follicle stem cell activity and potentially explaining hair loss associated with beta-blockers and androgenic alopecia.

Hox genes control hair follicle stem cell regeneration in different body regions.

This study suggests that the DORN1 receptor may play a role in eATP-induced changes in stomatal aperture in Arabidopsis thaliana, but not in the eADP signaling pathway.

This study found that neurosteroid withdrawal significantly increased hippocampal GABA-A receptor α4 subunit expression in female mice, confirming an association between neurosteroid withdrawal and altered receptor expression.

In this study, researchers observed distinct morphological differences in hair follicles of mutant mouse genotypes, influenced by the expression levels of keratin2-6g, which is essential for proper hair follicle development.

This article examines microscopic structural differences and pigment distribution in various rabbit hair colors and reports no clinical results.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This study found that stabilized beta-catenin is crucial for activating stem cell transition from quiescence to proliferation in hair follicles by influencing gene expression within the stem cell niche.

This study found that adipocytes play a crucial role in skin wound healing by facilitating fibroblast recruitment and dermal reconstruction during the healing process.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

This study found that hypertrophic chondrocytes at the fracture callus border may convert to osteoblasts, influenced by vasculature and pluripotency gene expression.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This study found that overexpression of PKCα in mouse epidermis increases expression of specific proinflammatory mediators and induces inflammation but does not significantly affect epidermal differentiation, proliferation, or tumor promotion with TPA.

In this study, the researchers found that alopecia in VDR null mice is likely due to issues with hair cycle initiation rather than defects in keratinocyte proliferation or differentiation.

This study found that postnatal treatment with recombinant EDA normalized adult teeth, improved sweating, and restored normal lacrimation in dogs with XLHED, suggesting its potential as a treatment for the condition.

In this study, researchers showed that the CAP1 gene regulates root hair growth in plants by modulating cytoplasmic ammonium levels and maintaining calcium gradients, highlighting its role in ammonium homeostasis.
