This case report describes a patient with mutations in both alleles of the vitamin D receptor who exhibited hair loss clinically indistinguishable from generalized atrichia with papules, suggesting a potential genetic pathway shared with the hairless gene.

This study found that supplementing Angora goats with whole field bean seeds postpartum did not prevent weight and body condition losses but was associated with improved mohair growth and kid weight gain, likely due to better nutrient partitioning towards lactation and hair growth.

This study found that Avicennia marina extract significantly inhibited 5α-reductase type 1 activity in human hair dermal papilla cells, suggesting its potential use for treating androgenic alopecia.

Oral 5-alpha reductase inhibitors do not increase breast cancer or benign breast disorder risk in women.

In this study, researchers found that AGD1 is crucial for membrane recruitment during root hair development in Arabidopsis thaliana, with its pleckstrin homology domain essential for targeting specific plasma membrane regions.

This study found that specific proteins associated with fiber structure, hair growth, and fatty acid synthesis, including the DSC2 gene, may influence wool and hair characteristics in sheep and goats.

This study found that alopecia areata patients had a higher serum CRP/albumin ratio compared to healthy controls, and this elevation was linked to disease severity, indicating its potential as an inflammatory marker.

Azathioprine may be an effective treatment for severe hair loss.

This meta-analysis suggests that the G allele of AR StuI polymorphism might be a potential risk factor for AGA, particularly in white populations.

Triamcinolone acetonide injections help regrow hair in alopecia areata patients.

This study suggests that androgen receptor CAG polymorphisms may not significantly influence androgenetic alopecia susceptibility in Korean men.

This study hypothesizes that the curling of hair may result from the contraction of the Arrector Pili Muscle, contributing to the diverse types of curly hair.

This phase 3 trial found that over 50% of adolescents with severe alopecia areata achieved successful hair regrowth after 52 weeks on baricitinib 4-mg, with no new safety concerns reported compared to existing safety profiles.

This study evaluated a chemically modified siRNA, AR-27 E-Chol, which effectively promoted hair regrowth and reduced androgen receptor gene expression in a DHT-induced mouse model of androgenetic alopecia, suggesting its potential as a novel therapeutic candidate.

In this study, researchers identified two significant genetic polymorphisms in the 3'-UTR of the HSP70 gene in Moa buffalo, which may play an important role in heat adaptation, providing insights for conservation and performance improvement in tropical climates.

This study found that baricitinib was effective in regrowing eyebrow and eyelash hair in patients with severe alopecia areata, with similar improvements observed in both clinician-reported and patient-reported measures.

In this study, both gel and microemulsion formulas containing waru leaves and Java Tamarind extracts were found to have similar in vivo hair growth activity in rabbits.

This study found that a combination of ciclosporin and Miglyol 812 was effective in treating sebaceous adenitis in rabbits, with significant improvement in skin condition and hair regrowth.

This study evaluated the potential toxicity of oral dihydroartemisinin in SD rats, finding that female rats experienced greater toxic effects than males, particularly at higher doses, but these effects were reversible after a 4-week recovery period.

In this study, no significant change in androgen receptor gene expression was found in females with recurrent spontaneous abortion, but a mutant genotype may offer some protection against the condition.

This study found that carbon and nitrogen isotope analysis of cattle hair reflects dietary and farm system differences, offering insights into cattle nutritional ecology and agroecosystem characteristics.

In this study, the researchers observed that Eda mRNA expression in goat skin peaks during the catagen phase of the hair cycle, suggesting its involvement in hair cycle regulation.

This study observed that intralesional Triamcinolone acetonide injections were generally safe and effective for alopecia areata, with most patients experiencing good hair growth responses, though side effects like pain and atrophy were noted.

This study reported that cognitive biopsy diagnosed prostate cancer in 44% of patients with at least one previous negative biopsy, with higher detection rates in lesions classified as PI-RADS 4 and 5.

In a mouse hair-growth model, this study found that the optimized compound 39 matched the efficacy of pyrilutamide for androgenic alopecia, with faster response and maintained safety, suggesting it as a promising topical AR antagonist with reduced systemic toxicity risk.

This study identified 2884 long non-coding RNAs (lncRNAs) associated with hair follicle cycling in yaks and highlighted sequence conservation with cashmere goats, suggesting potential pathways for hair growth regulation.

This study highlights the use of dermatoscopy as a valuable tool for diagnosing and monitoring alopecia areata, noting that specific hair shaft alterations such as exclamation-mark hairs and black dots are indicators of active disease, while vellus hairs signal early regrowth.

This study identified a new gene, mrp4, in mice, which suggests it may have a unique role in the growth and development of hair follicles in the ears and tails.

This study identified a new gene in sheep, KRTAP36-2, discovering variants associated with wool yield. Variations in this gene were linked to the efficiency of fleece conversion from greasy to clean, which may enhance wool production.

The researchers reported that keratin 33A is a structural protein specific to goat cashmere hair, with increased winter expression in high-cashmere-producing breeds.
