This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This study found that supplementing pregnant and lactating mice with high dietary copper improved survival and physical traits in mice carrying the crinkled mutation, suggesting copper's role in modulating gene expression.

Melatonin affects when and how goat hair follicle genes turn on and off during growth cycles.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

Melatonin affects when and how goat hair follicle genes turn on and off during growth cycles.

This review discusses three decades of progress in feather development, regeneration, and evolution, with no new experimental results; it highlights feathers' potential as a model for morphogenesis studies.

This study found that inducing Atoh1 expression in transgenic mice is sufficient to generate new Merkel cells in the epidermis, with variations by skin location, developmental age, and hair cycle stage.

In this study, researchers observed that African spiny mice, Acomys cahirinus, are capable of regenerating skeletal muscle in dermal wound sites, unlike common mice, Mus musculus.

This study suggests that Merkel cell polyomavirus T antigen-positive cells resembling Merkel cell carcinoma may originate from epithelial cells in human hair follicles, potentially informing future transgenic mouse models for this cancer.

This review provides an overview of Hox genes, focusing on their evolutionary history, genomic organization, and roles in development, but reports no new study results.

This study identified novel genetic variants related to rare skin and hair disorders, expanding the understanding of conditions like COLED, EV, and monilethrix, including a newly discovered type I keratin gene, KRT31, as a cause for monilethrix.

This study examined two cases of bubble hair deformity using light and electron microscopy, suggesting that trauma to the hair shaft may contribute to this condition.

This report presents a case of hereditary elliptocytosis in a 37-year-old woman with iron deficiency anemia, identifying a high percentage of elliptocytes in her blood after treatment.

This study reported that using photomnemonics facilitated accurate histopathologic interpretation of horizontal scalp sections in distinguishing between nonscarring and scarring alopecias by dermatopathologists and residents in a validation test.

In this study, researchers observed that twins with a novel de novo nonsense variant in HRAS exhibited distinctive features, including neuropsychiatric symptoms, potentially indicating a wider clinical spectrum for conditions known as RASopathies.

In this study, a novel heterozygous transition mutation in the KRT86 gene was identified, which may be pathogenic for monilethrix in a Chinese family.

This review outlines the role of mechanical forces in the development of sensory organs like eyes and ears, emphasizing insights from recent animal studies and microfabricated organoid systems; it presents no new experimental results.

This study found that overexpression of a mutated ornithine decarboxylase transgene in mice led to complete hair loss, which could be prevented or reversed with an ODC inhibitor.

This study identified that spermidine-mediated activation of eIF5A by hypusination plays a significant role in Arabidopsis thaliana growth, flowering time, stress adaptation, and development, including changing root and aerial architecture.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

This study compiled an archive of 684 genes associated with monogenic hair disorders, identifying previously unrecognized components of Hippo signaling and proposing a new biologically-grounded disease taxonomy.

This study found significant inconsistencies in coat color terminology for the Sicilian Mastiff, revealing greater phenotypic diversity through photography and genetic analyses than recognized in breed registry data.

This study identified key genes and pathways involved in the growth and development of forest musk deer hair follicles, providing insights into molecular regulation and laying groundwork for future research on related diseases.

This study identified specific keratin-associated protein genes that are highly expressed in different varieties and sexes of Angora goats, providing insights for improving mohair development through targeted breeding strategies.

This study highlights a case of trichotillomania with trichophagia in a 7-year-old girl, illustrating the medical complications and need for awareness and collaborative management of this condition, often misdiagnosed due to stigma.

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 found that the microRNAs oar-miR-23b and oar-miR-133 inhibit the proliferation and migration of sheep dermal fibroblasts, impacting the development of hair follicles in superfine wool sheep by targeting the genes TGFβ2 and NOTCH1.

Monilethrix is a rare, inherited condition causing fragile hair and hair loss, with no cure but some treatments may help.
