In this study, LHX2 and SOX9 were found to mark distinct epithelial progenitor cell populations within human hair follicles, suggesting roles in maintaining the hair follicle epithelium.

In this study, electrical stimuli at low voltage and frequency settings promoted hair growth in vitro and in rabbit models, possibly by activating pathways like Wnt/β-catenin.

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.

In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

This study found that monilethrix in three unrelated European families is linked to the type II keratin gene cluster on chromosome 12q13, with no evidence of defects in type I keratins.

This case study reports that an infant with maple syrup urine disease developed acrodermatitis dysmetabolica due to low isoleucine levels, and increasing the isoleucine dose improved the condition.

This study found that MAP-2 is intensely expressed in the companion layer of the hair follicle, suggesting its potential importance to follicle integrity and possible involvement in some types of alopecia.

In this study, a missense mutation in the MAP2 gene was found to be associated with reduced hair follicle density, leading to the hairless phenotype in pigs.

This study suggests that the MAPK/ERK signaling pathway plays a role in the regulation of cell proliferation, apoptosis, and cycling in rat urethral plate fibroblasts affected by finasteride-induced hypospadias.

This study demonstrated that lactate dehydrogenase activity is notably high in quiescent hair follicle stem cells within mouse skin using a specific enzymatic activity assay.

This study found that Euph E and Euri A showed strong anti-inflammatory activity and modulated cytokine and immune functions in macrophages, related to specific signaling pathways.

In this study, around 1% of proteins in skin fibroblasts significantly changed in response to reductive stress, affecting collagens and MAPK signaling pathways.
