This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

This review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This genome-wide association study identified 20 genetic signals at 15 risk loci related to severe acne, revealing new insights into its genetic predisposition, particularly affecting skin structure and maintenance.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This study identified several compounds from traditional Chinese medicines that may inhibit prostaglandin D2 synthase, potentially providing promising candidates for treating androgenic alopecia with minimal adverse skin reactions.

This review discusses how the p53 tumor suppressor gene helps maintain adult tissue homeostasis by promoting the removal of DNA-damaged cells, with implications for treating age-related diseases and p53-deficient cancers; it reports no new results.

Acne is significantly influenced by genetics, and understanding its genetic basis could lead to better, targeted treatments.

This article reviews potential causes and treatments for sensitive skin and reports no new clinical results; the authors emphasize neurogenic inflammation and cosmetic choices as key factors in managing the condition.

This article discusses the advances in understanding wound-induced hair follicle neogenesis (WIHN) and highlights the roles of specific signaling pathways and cellular plasticity, noting no clinical results but suggesting potential areas for further research.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.
