This study on Dorper sheep identified important genetic factors influencing hair follicle development, finding that expression patterns and genes like DBI, FZD3, and ZDHHC21 play a crucial role in wool shedding, which could help improve understanding of mammalian skin-related traits and human hair advancement.

This study found that flumethasone administration in Merino wethers led to variations in wool shedding and initial reductions in wool growth, with full recovery generally observed within 60 days post-treatment.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This study found that infused mouse epidermal growth factor induced wool follicle involution through a quasi-physiological process similar to catagen and a separate pathological action, resulting in fleece 'break' or shedding.

This study found that twice-daily intradermal injections of mouse epidermal growth factor in Merino sheep resulted in dose-dependent changes in wool follicles and fibres, including induction of catagen and subsequent regeneration.

This study found that STAT3 directly inhibits the sheep FST gene and cell proliferation, shedding light on the molecular mechanisms of hair follicle development and wool characteristics.

This study found that cyclophosphamide treatment in cashmere goats significantly increased cashmere yield by inducing shedding without affecting fiber length, with a 20 mg/kg body weight dose being optimal for hair removal and regrowth.

This study found that sheep wool follicles actively oxidize acetate and glucose, suggesting the involvement of the TCA cycle for compound synthesis and the potential role of the pentose phosphate pathway in ribose production for RNA and DNA.

This study found that concurrent administration of cycloleucine with ethionine prevented the weakening of wool fibers in sheep, whereas reduced glutathione did not have the same effect.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This study found that Super Merino sheep have a higher wool follicle density, finer fleece, and distinct gene expression compared to Small Tail Han sheep, which may inform future breeding and genetic interventions.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This study found that crossbred lambs fed liquid diets with reconstituted cow's milk initially grew wool without crimp, with crimp resuming two weeks post-weaning.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

This workshop review from the Australian Hair and Wool Research Society discusses findings in cutaneous biology and endocrinology but presents no new research results.

This study identified important lncRNAs and genes associated with cashmere shedding in goats and explored their regulatory interactions, providing insights into the molecular mechanisms that may underlie this phenomenon.

This study describes a staining technique that differentiates medullary from cortical keratin in sheep and goat hair using Ziehl-Neelsen's carbol-fuchsin in skin biopsy sections.

This article reviews the historical development of understanding the hair growth cycle, particularly anagen, catagen, and telogen phases, and reports no new clinical findings.

This study found that manipulating prolactin levels in New Zealand Wiltshire sheep induces wool follicle growth cycles, revealing gene expression changes that suggest roles for specific genes in follicle function.

In this study, researchers found that reducing FGF20 expression in dermal papilla cells of fine-wool sheep impedes the growth and differentiation of hair follicle stem cells, providing insights into wool trait improvement and regenerative medicine applications.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

A horse's sudden hair loss was caused by an allergic reaction to a coat conditioning powder.

In this study, researchers analyzed skin samples from Dorper sheep to identify 395 differentially expressed long non-coding RNAs (lncRNAs) linked to hair follicle growth phases, suggesting these lncRNAs may play a role in the regulation of hair shedding through pathways like estrogen and PI3K-Akt signaling.

Intermittent iron and nutritional supplements can help reduce hair loss.

This study reports that hair fibers degrade most in acidic sandy clay, while silicone oil treatment is effective for conserving various hair types and artifacts.

In this study, using light masks to extend photoperiod was effective for maintaining the summer coat in horses and accelerating shedding in outdoor horses, but timing was crucial for success.

In this study, ceruloplasmin and keratin 4 were identified as markers that differentiate between growing and resting phases in cashmere goat hair follicles, with keratin 4 being a potential marker for the onset of a new hair cycle.

This study identified specific genetic markers related to wool quality in Rambouillet sheep, which may aid breeders in making informed selection and breeding decisions for improved fine wool production.

In this study, researchers used the CRISPR/Cas9 system to edit the FGF5 gene in Dorper sheep, observing increased density and finer wool, along with changes in cortisol levels and antioxidant enzyme activity linked to hair follicle development.
