This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

In this study, mycorrhizal fungal inoculation was associated with increased root-hair growth and enhanced drought tolerance in trifoliate orange by modulating auxin synthesis and transport under water stress conditions.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This article discusses the structure of the human type II 5 alpha-reductase gene and reports no new experimental results.

This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study found that human hair follicles express ATP-sensitive potassium channels, suggesting that minoxidil acts on these channels and that drugs targeting them may treat hair disorders.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This article discusses the potential genetic basis of central centrifugal cicatricial alopecia in women of African ancestry but does not provide new research results.

This study found that serum androgen levels in premenopausal women may be influenced by genetic variants of the androgen receptor and estrogen receptor β genes.

This study found that the retinoid all-trans retinoic acid induced a catagen-like stage in human scalp hair follicles, suggesting upregulation of TGF-beta2 as a contributing mechanism.

In this study, researchers identified a specific T cell receptor associated with carbamazepine-induced severe cutaneous adverse reactions, demonstrating its potential for therapeutic development in patients with the HLA-B*15:02 genotype.

In this study, specific versican expression was observed in the anagen phase of human hair follicles, suggesting its importance in maintaining normal hair growth.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

This study found that simultaneously inhibiting both KLK5 and KLK7 proteases completely rescued skin barrier defects in a mouse model of Netherton syndrome, suggesting both should be therapeutic targets.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study details the isolation and characterization of the human type II 5 alpha-reductase gene, which may play a role in male pseudohermaphroditism, prostate cancer, and benign prostatic hyperplasia.

This study found that the AR-E211 A allele is associated with a lower risk of both metastatic prostate cancer and androgenetic alopecia in an Australian population.

This study found that LGR5 is uniquely expressed in human corneal endothelial cells and maintains endothelial cell phenotypes while inhibiting mesenchymal transformation through the Wnt pathway.

This study identified that a deficiency in the palmitoyl transferase enzyme, due to a mutation in the Zdhhc13 gene, led to severe physiological abnormalities in mice, including skin, bone, and systemic amyloid issues.

This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.
