This review reports that natural compounds show promise in slowing skin photoaging by targeting cellular pathways in keratinocytes and fibroblasts. However, comprehensive clinical studies are needed to verify their efficacy and safety.

This study found that suppressing Jagged1 in epidermal stem cells disrupted Notch signaling and resulted in poor-quality wound healing, suggesting a potential therapeutic target for improving wound repair.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

This study found that glucose metabolism supports hair inductive gene expression and hair shaft elongation in dermal papilla cells, suggesting potential applications for in vitro hair follicle generation.

Europe strengthened medicine regulations, increased protection against counterfeit drugs, and made it tougher to challenge comparative advertising, while also focusing on patent law enforcement and updating plant protection rules.

In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

This study observed that selectively activating activin in the epidermis of mice enhanced reepithelialization during wound healing without altering the quality of the healed wound.

This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

In this study, researchers found that microRNAs and specific target genes, such as MiR-195 and genes like CHP1, SMAD2, FZD6, and SIAH1, play significant roles in regulating hair follicle initiation in cashmere goats.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This study used computational modeling to identify key genes and miRs involved in cardiac aging, finding a strong relationship supported by literature and some experimental validation in aged mouse hearts.

This computational study developed a regulatory model linking key genes and miRNAs to cardiac senescence, validated by connecting 94% of these elements to existing cardiac aging research.

This study found that stimulating the olfactory receptor OR2AT4 in human hair follicles with a synthetic sandalwood odorant promotes hair growth ex vivo by decreasing apoptosis and increasing IGF-1 production.

In this study, miR-218-5p was found to enhance hair shaft growth and positively regulate the Wnt signaling pathway by targeting SFRP2 during skin and hair follicle development.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This review highlights REV7's crucial roles in maintaining genome stability, its implication in several cancers, and its association with poor prognoses and treatment resistance, while also noting that REV7 suppression may improve chemotherapy sensitivity.

This review synthesizes both traditional and emerging molecular mechanisms of tissue remodeling across different organs, aiming to establish a theoretical basis for precision interventions in pathological conditions, according to the authors.

This study found that the natural product Shi-Bi-Man significantly promoted hair regeneration in cynomolgus monkeys, increasing hair follicle number and activation by boosting specific protein markers and interactions in Laminin-related pathways.

This study found that type 2 immunity, especially involving ILC2 cells, helps maintain skin homeostasis by regulating the proliferation and community stability of hair follicle epithelial cells in the presence of Demodex mites.

In this study, SFRP1 expression was found to be upregulated in hair follicles from men with androgenetic alopecia, with the transcription factor FOXC1 playing a significant role in its regulation.
