research The transcriptional landscape of seasonal coat colour moult in the snowshoe hare
Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.
research Function and underlying mechanisms of seasonal colour moulting in mammals and birds: what keeps them changing in a warming world?
Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.
research Environmental Influences on the Hair Follicle
Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.
research Responses of hair follicle gene expression to the cold season and growth promotion technology in Angus and Brahman cattle
Angus cattle grow faster and are more feed-efficient than Brahman, especially with growth-promoting systems, and gene expression changes with cold and treatments.
research Symmetrical alopecia in the dog
The conclusion is that a systematic approach is key for treating symmetrical alopecia in dogs, but treatment may not always be necessary.
research Hair coat characteristics in Friesian heifers in the Netherlands and Kenya : experimental data and a review of literature
Friesian heifers take about 18 months to adapt to Kenya's climate, with hair changes not strongly linked to weight gain.
research The Effect of the Season, the Maintenance System and the Addition of Polyunsaturated Fatty Acids on Selected Biological and Physicochemical Features of Rabbit Fur
Outdoor living and omega-3 supplements improve rabbit fur quality.
research Hormonal control of pelage cycles in the short tailed weasel (Mustela erminea bangsi)
The pituitary gland controls seasonal fur color changes in weasels.
research Hair Color, Molt, and Testis Size in Male, Short-Tailed Weasels Treated with Melatonin
Melatonin causes weasels to grow white fur and become reproductively inactive.
research Temporary Relocation during Rest Periods: Relocation Stress and Other Factors Influence Hair Cortisol Concentrations in Horses
Moving horses to new places can increase their stress levels, as shown by higher stress hormone in their hair.
research Seasonal Moulting in Adult Male Raccoon Dog (Nyctereutes procyonoides)
Adult male raccoon dogs shed their winter fur in spring and grow new fur for winter in autumn.
research Androgen receptors are only present in mesenchyme-derived dermal papilla cells of red deer (Cervus elaphus) neck follicles when raised androgens induce a mane in the breeding season
Red deer only have androgen receptors in neck hair cells for mane growth during breeding season.
research MELATONIN
Melatonin may help with sleep issues, depression, and cancer, but more research is needed.
research Module-based complexity formation: periodic patterning in feathers and hairs
The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.
research Physiological Regeneration of Skin Appendages and Implications for Regenerative Medicine
The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.
research Possible relationships between the physical conditions of cattle and the occurrence of structural modifications of their coat hair
Vitamin A deficiency changes cattle hair structure, while pregnancy may improve it, suggesting hair can indicate cattle health.
research An integrative view of mammalian seasonal neuroendocrinology
The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.
research Hair Follicle Development of Rex Rabbits Is Regulated Seasonally by Wnt10b/β-Catenin, TGFβ-BMP, IGF1, and EGF Signaling Pathways
Winter provides the best fur quality for Rex rabbits due to seasonal changes in specific signaling pathways.
research Studies of normal moult and of artifically induced regeneration of pelage in peromyscus
Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.
research Les hormones sexuelles et la peau : questionnaire à l'attention des vétérinaires praticiens. Mise à jour bibliographique et synthèse
Sex hormones affect dog skin conditions, but more data is needed.
research Study of seed hair growth in Populus tomentosa, an important character of female floral bud development
Poplar seed hairs grow from the placenta at the ovary base, with endoreduplication playing a key role in their development, and share similar cellulose synthesis processes with cotton fibers.
research Morpho‐regulation in diverse chicken feather formation: Integrating branching modules and sex hormone‐dependent morpho‐regulatory modules
Sex hormones, especially estradiol, can change chicken feather shapes and colors.
research The Retinoic-Acid-Related Orphan Receptor Alpha May Be Highly Involved in the Regulation of Seasonal Hair Molting
RORA plays a key role in controlling seasonal hair molting by affecting hair follicle cell activity.
research The Role of PPARβ/δ-Related Lipid Metabolism in High-Altitude Adaptation of Yak Coat Based on Proteomics and Metabolomics
PPARβ/δ helps yaks adapt to high altitudes by regulating lipid metabolism in their coats.
research Effects of Seasonality and Pregnancy on Hair Loss and Regrowth in Rhesus Macaques
Hair loss peaks in spring and regrowth in late summer, with pregnant females losing the most hair.
research The seasonal development dynamics of the yak hair cycle transcriptome
Yak hair growth is influenced by genes and hormones, helping them adapt to alpine environments.
research Comparative study on seasonal hair follicle cycling by analysis of the transcriptomes from cashmere and milk goats
Cashmere and milk goats have different hair growth cycles and gene expressions, which could help improve wool production.
research Noninflammatory, Nonpruritic Alopecia of Horses
Some horses lose hair without inflammation or itching due to various conditions, and while mainly a cosmetic issue, diagnosis requires examination and biopsies, and breeding is not advised if it's hereditary.
research Hereditary, Congenital, and Acquired Alopecias
The conclusion is that different types of hair loss in dogs and cats can be cosmetic or serious, and affected animals should not be bred.
