This study identified genetic differences between Australian White Sheep and Hu Sheep that may explain their distinct pelage types, with a focus on subcutaneous adiposity and immunoregulation. The findings suggest potential targets for breeding climate-resilient sheep, enhancing our understanding of heat tolerance in these breeds.

This study identified novel genetic variations in the KRTAP22-2 gene among eight sheep breeds but found no association between these genotypes and wool fibre traits, indicating possible species-specific differences compared to goats.

In this study, researchers found that the keratin-associated protein 36-1 gene (KRTAP36-1) allele C is linked to variations in mean fibre curvature of fine wool in Chinese Tan lambs, suggesting its role in their distinctive curly coat.

This study identified various non-coding RNAs (ncRNAs) and mRNAs differentially expressed in skin tissues of two coat types of Jinlan Cashmere Goats, suggesting potential regulatory networks that could inform precision breeding strategies to improve cashmere quality and yield.

This study found that in sheep, the microRNA oar-miR-377 regulates hair follicle development by targeting the SLC24A2 gene, and identified a genetic variation associated with wool quality, suggesting potential markers for breeding.

This study investigated circRNA expression in Zhongwei goat skin at different growth stages and found that certain circRNAs, such as circRNA8782 and circRNA3173, may play roles in regulating wool curvature by affecting signaling pathways and fibroblast proliferation.

In this study, researchers analyzed the skin proteome of Alpine Merino sheep to identify proteins and pathways related to wool fiber diameter, finding that cyclic adenosine monophosphate and certain signaling pathways may play a role in this trait.

This study found that EGF and KGF were expressed at different levels in the skin of Gansu alpine Merino sheep, suggesting these factors influence wool fineness.

This study found that chondroitin sulfate levels were higher than hyaluronic acid in skin and hair follicle samples, with the highest concentration observed in prekeratin of hair follicles and wool fibers.

This study identified a gene mutation in the LIPH gene associated with inherited hair loss and hair growth defects in certain populations, suggesting lipase H plays a role in hair development.

This review discusses keratin disorders and potential RNA interference therapeutics, reporting no new clinical findings but highlighting the promise of siRNA for future treatments.

In this study, researchers identified nine new sheep keratin genes, highlighting species-specific differences in the expression and compartmentalization of wool-related keratin genes compared to humans.

This research observed that sheep and rabbit KAP6 genes, expressed in hair follicle cells, have high sequence similarity and indicate conservation due to evolutionary selection pressures.

This study found that trichoscopy can diagnose genetic hair shaft abnormalities without plucking or cutting hair, by visualizing characteristic features in a single session.

This study found that zinc is primarily located in the tails of mature rat sperm, associated with -S-S-bonded structures, and suggests a possible similarity in zinc interactions between sperm keratin and hair proteins.

This paper discusses the use of dermatoscopy as a fast, noninvasive technique for diagnosing hair shaft disorders and reports no new results; the authors highlight its advantages over traditional microscopy methods.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

This review identifies genetic mutations associated with congenital hair loss disorders in Japanese populations, particularly highlighting common LIPH gene mutations linked to woolly hair/hypotrichosis, and reports no new clinical results.

This article reviews various hair abnormalities observable through trichoscopy in conditions like monilethrix, trichorrhexis nodosa, and ectodermal dysplasias, with no new clinical findings reported.

This review examines hair shaft disorders, reporting limited evidence for treatments like minoxidil and oral retinoids, and emphasizes gentle hair care and genetic counseling for managing congenital cases.

This letter discusses congenital triangular alopecia (TTA), a non-scarring hair loss condition often seen in children, without reporting new clinical findings.

This study found that lipid extraction increased water diffusion in wool and hair fibers; the effect was more pronounced in hair, indicating lipids are crucial for water permeability.

This review highlights the light microscopic features of various infectious and non-infectious hair conditions and reports no new clinical results.

The researchers reported that exposure to long days after short-day treatment induced a synchronized, out-of-season wool growth cycle in New Zealand Wiltshire sheep, similar to cycles induced in other species.

This review proposes a new approach for categorizing and diagnosing unruly hair forms, building on previous literature and clinical experience, without presenting new clinical results.

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.

This paper reviews the genetic aspects of hair disorders and suggests that understanding these genes could advance treatment and diagnosis; it reports no new experimental findings.

This study conducted de novo transcriptome sequencing in sheep skin, identifying and annotating numerous unigenes, which may aid in improving wool quality and understanding hair follicle development.

This review discusses the prognosis and treatment options for hair shaft disorders, finding no studies but suggesting some disorders improve with specific treatments like minoxidil and retinoids, while gentle hair care remains essential.
