Slug (Snai2) helps regulate hair growth timing in mice.

This review discusses the molecular and functional aspects of the nude gene in skin biology, providing insights into its role and evolutionary development, but reports no new results.

This study reported that genetic testing is crucial for accurately diagnosing hypotrichosis, especially in cases with subtle symptoms or coexisting severe atopic dermatitis, as demonstrated in a young girl with a DSG4 gene mutation.

This review discusses the potential of miRNA-mediated hair growth treatments for androgenetic alopecia by targeting DKK1 to modulate the Wnt/β-catenin signaling pathway and reports no new clinical findings.

In this comprehensive review, researchers examine the p63 gene's crucial role in skin development and pathology, highlighting its regulation of cell processes and its potential therapeutic implications for disorders like ectodermal dysplasia.

This study found that a nonsense mutation in the Cst6 gene of mice leads to severe skin and hair abnormalities, suggesting that cystatin M/E is crucial for epidermal function and viability.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.

This study found that overexpression of the lncRNA AC010789.1 in hair follicle stem cells may suppress androgen alopecia progression by modulating several molecular pathways, suggesting a potential new treatment strategy.

A specific gene mutation causes complete hair loss in an Irish Traveller family.

This study found that RNase L acts as a regeneration repressor gene in mammals, as seen in Rnasel-/- mice which showed increased regenerative capacity and elevated Wound Induced Hair Neogenesis through enhanced IL-36α signaling, suggesting a tradeoff between regeneration and immune regulation.

This study found that the dark pigmentation pattern in Dun Mongolian horses' "Bider marking" is closely associated with higher protein levels and specific localization of MITF and WNT3A, suggesting these are key factors in its formation.

This study presents two new mouse models using the CreER T2-loxP system to target and study melanocytic cells, with implications for melanoma research.

In this study, treatment with recombinant DKK2 was shown to significantly stimulate hair progenitor cell growth and enhance hair shaft elongation in ex vivo human hair follicle cultures by activating the Wnt/ẞ-catenin signaling pathway, suggesting a potential role for DKK2 in promoting hair growth.

This study found that selectively inactivating ribonucleotide excision repair in mouse epidermis leads to DNA damage, keratinocyte intraepithelial neoplasia, and squamous cell carcinoma, indicating a potential tumor-promoting mechanism related to compromised genome maintenance.

This study found that inhibiting the interaction between CXXC5 and Dishevelled could stimulate hair regrowth in mouse models by enhancing WNT/β-catenin signaling, suggesting a potential therapeutic strategy for hair loss involving compounds that block this interaction, such as interfering short peptides.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

In this study, transgenic mice expressing a truncated form of latent transforming growth factor-β-binding protein exhibited altered hair cycles due to increased active transforming growth factor-β, impacting keratinocyte proliferation and hair cycle phases.
