This study observed that distinct subsets of Hoxd genes in murine vibrissae and chicken feather primordia are regulated by different lineage-specific enhancers, indicating evolutionary changes in chromatin topology contribute to transcriptional robustness.

This study found that the metabolic profile of finasteride in pigs closely matches that of humans, supporting the use of pigs for studying human drug metabolism.

Mouse Scube3 affects teeth, tongue, vibrissae, and eye development, but not facial structure or limb growth.

In this study, researchers examined the histological structure of wild boar skin from three anatomical regions and found it comprises three main layers: epidermis, dermis, and hypodermis, containing various cell types and structures such as hair follicles, sebaceous glands, and fat cells.

This study reported variable expression levels of TRα and CRABPII genes during the prenatal development of cashmere goats, contributing to an understanding of hair follicle formation in these animals.

This study identified two novel genes, pmg-1 and pmg-2, expressed in various skin and gland tissues and potentially involved in the differentiation of epithelial cells in epidermal appendages.

This study investigated the interdigital glands of moose, detailing their unique green hair coloration and the function of sebaceous and sweat glands, particularly during the rut period.

This study documented clinical cases of dermatophytosis in two free-ranging southern chamois in the Eastern Pyrenees, with Trichophyton mentagrophytes identified in both animals.

This case report describes a 9‐year‐old red panda with progressive hair loss linked to bilateral granulosa cell tumors, suggesting an underlying endocrine abnormality.

This study found that examining the microscopic and ultramicroscopic structures of donkey and horse hair can help differentiate between the species based on distinct differences in hair cuticle and brain substance patterns.

This study found that distinct low-threshold mechanoreceptors innervate different hair follicle types in mice, suggesting that these follicles serve as unique mechanosensory structures in touch perception.

This review outlines recent advances in stem cell and tissue engineering technologies in regenerative medicine and wildlife conservation, reporting no new clinical results.

This study found that D-peptide crosslinked MAP hydrogel accelerated material degradation in vivo but significantly enhanced skin regeneration, suggesting an adaptive immune response can drive regenerative healing even with rapid scaffold breakdown.

This review discusses the use of hair cortisol concentration as a marker for chronic stress and long-term cortisol secretion in animals, highlighting its benefits and the need for standardized sampling protocols.

In vitro, this study suggests that CRH may act as an autocrine hormone in human sebocytes, influencing lipid synthesis and potentially impacting skin disorders related to alterations in sebaceous lipid formation.

This review discusses case reports of autoimmune diseases following vaccination and the challenges of establishing a clear epidemiological connection, urging further investigation into vaccine-induced autoimmunity.

This review discusses how dehydroepiandrosterone (DHEA) may exert its biological effects through multiple receptors and reports no new clinical results.

This review discusses the complex effects of testosterone on the brain, emphasizing sex differences, and reports no clinical results; the authors highlight the inconsistencies in current study findings.

This study found that Demodex folliculorum and Demodex brevis mites can cause eyelid follicular and glandular changes, potentially contributing to ocular disease in humans.

This article discusses the role of androgens in metabolic and reproductive health and reports no new experimental results; the focus is on androgen receptor activation by testosterone and 5α-dihydrotestosterone.

This review discusses the relationship between skin microbiome changes and conditions such as ageing and skin disease, emphasizing the need for further research, but reports no new findings.

This study found that hair cortisol concentration in free-ranging brown bears is influenced by handling methods, body condition, and potentially both short- and long-term stressors.

This review discusses the commonly observed pathological findings in progeroid mouse models and highlights the importance of understanding mouse strain backgrounds and progeria-related phenotypes for accurate pathology data interpretation.

This review discusses the free hormone hypothesis for measuring "free" testosterone and critiques its theoretical basis and clinical application, noting it lacks critical empirical testing and has inconsistent utility in assessing androgen status.

This study found that alkylation of kerateine cysteine residues created a cell-compatible method for controlling hydrogel erosion rates and therapeutic agent release in keratin-based systems.

This review discusses the role of the enzyme Δ9-desaturase-1 in skin lipid regulation and whole-body energy balance in mice and reports no new experimental results.

This study found that lower salmon availability was associated with higher stress hormone levels in grizzly and black bears, influencing their physiological responses and competitive behaviors.

This study explored the expression and potential functions of long non-coding RNAs in the skin pigmentation of Koi carp, revealing their involvement in pigmentation and differentiation mechanisms.

This review discusses the advantages, applications, and current trends of dissolving microneedles for drug delivery across various therapeutic areas and reports no new clinical results.
