This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.

This review examines the roles of Hedgehog and Gli proteins in mouse embryonic mammary development and suggests that Gli3-repressor-mediated off-state of Hedgehog signaling determines mammary fate over hair follicle fate.

In this study, hair follicle germs containing vascular endothelial cells showed improved hair regeneration and morphogenesis-related gene expression in mice, suggesting a promising strategy for hair regenerative medicine.

This review examines the evolution of human skin pigmentation and its genetic basis, suggesting that variations might be due to a few interacting gene pairs, and reports no new research findings.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

This study found that recombinant human FGF9 expressed in Arabidopsis thaliana oil bodies significantly promoted the proliferation of NIH/3T3 cells.

This study found that levels of the protein MAGP-1, important for skin elasticity, decrease with aging and photoexposure, potentially contributing to skin fragility, sagging, and enlarged pores.

This study observed that dermal papilla cell aggregates showed increased viability and gene expression on softer 3D substrates, indicating the importance of substrate stiffness in cellular behavior.

This study reports a unique case of common variable immunodeficiency with autoimmunity linked to a heterozygous S250C variant in the autoimmune regulator gene, suggesting a potential molecular basis for this combination.

This review explores how androgen administration might help alleviate inflammation and mitochondrial impairment in traumatic brain injury but reports no new experimental findings, calling attention to the need for further investigation.

This review emphasizes the potential of repurposing topical L-thyroxine for skin ulcers and telogen effluvium and highlights the need for further exploration of its use in dermatology.

This study found that lncRNA-599547 positively regulates the expression of the Wnt10b gene by interacting with miR-15b-5p, enhancing the inductive property of dermal papilla cells in cashmere goats.

This study suggests that dietary vitamin A may influence alopecia development and progression, but the mechanisms remain unclear, highlighting the interplay between genetics and nutrition in these hair loss conditions.

This study identified key genes and pathways involved in the seasonal hair cycle regulation of yak, uncovering molecular mechanisms that may aid in understanding their adaptation to alpine environments.

This study reported that wound-resident mesenchymal cells can be reprogrammed to generate epithelial tissues, aiding in the closure of large, non-healing ulcers without signs of malignant transformation.

Buschke-Ollendorff syndrome is a rare genetic disorder causing skin and bone changes, with some cases also showing ADHD or developmental delays.

This study identified 674 differentially expressed proteins in the skin tissues of male and female Chinese merino sheep, suggesting gender-specific molecular mechanisms that may affect wool traits.

This study assessed pharmacogenomic variants and chemotherapy-related toxicity profiles in Tanzanian children with cancer, reporting notable genetic diversity that may influence toxicity but did not evaluate genotype-toxicity associations.

This study found that 3-hydroxypropionic acid improved the function of hair follicle cells under oxidative stress, suggesting potential as a treatment for stress-related hair loss.

In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.

Senescent melanocytes in nevus skin boost hair growth.

Staphylococcus epidermidis affects hair growth and metabolism, suggesting it could help manage hair growth issues.

This study identifies gene-regulatory networks related to genetic variants in skin and hair diseases, suggesting that dermal papilla cells are crucial in androgenetic alopecia.

This article highlights the prevalence of iron deficiency, with or without anemia, as a significant factor in diffuse nonscarring hair loss in women, particularly affecting certain groups such as menstruating women and vegetarians.

This study investigated the roles of long non-coding RNAs in mouse hair follicle stem cells, using sequencing to identify potential biomarkers and targets for treatments in both mice and humans.

This review discusses the pathogenesis and treatment approaches for non-scarring alopecia and acne, highlighting the role of genetic factors, androgens, and metabolic risks but reports no new clinical results.
