In this study, a clear pattern of selective sweep was observed for the SLC24A5 gene, with high linkage disequilibrium and low haplotype diversity, but no clear correlation with UV radiation intensity was found.

This study found that in sheep, the microRNA oar-miR-377 regulates hair follicle development by targeting the SLC24A2 gene, and identified a genetic variation associated with wool quality, suggesting potential markers for breeding.

In this study, researchers found that oar-miR-377 regulates secondary hair follicle development in sheep by downregulating the SLC24A2 gene, and a specific SNP in oar-miR-377 is significantly associated with wool fiber diameter variation in Chinese Merino sheep.

This study found that anagen stage protein homogenates and specific epitopes from melanogenesis proteins activated CD8 T cells, suggesting alopecia areata is an anagen-specific disease.

In this study of four Chinese goat breeds, black goats exhibited significantly higher melanin content, while Inner Mongolian cashmere goats had longer fiber lengths. These findings highlight genetic variations in coat color and fiber length, informing future breeding programs.

This study found that among men over 70, certain genetic variants associated with skin pigmentation affect serum PSA levels, with implications for how sun sensitivity and exposure may influence prostate cancer risk.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This study found that the EDAR 1540T/C genetic variant is significantly associated with hair thickness variation in Japanese populations, enhancing previously observed associations in Southeast Asian groups.

This study revealed that differential gene and protein expression in the "Yufen I" H line chicken breed is crucial for Columbian plumage coloration, particularly in the melanogenesis pathway.

This study found that serum calcium, serum ferritin, and vitamin D3 levels were lower in students with premature graying of hair compared to controls, suggesting a potential role in the condition.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This article discusses strategies for changing hair color by regulating target genes in hair follicles using advanced delivery systems, but it reports no new experimental findings.

This article discusses the use of forensic DNA phenotyping to infer physical characteristics from biological samples without a reference sample, aiding investigations but raising ethical and legal concerns.

DNA can predict physical traits like eye and hair color accurately, especially in Europeans, but predicting other traits and in diverse populations needs more research.

This systematic review and meta-analysis found 30 genetic loci associated with skin ageing phenotypes, noting shared biological pathways in aspects like pigmentation and wrinkling; researchers suggest further studies targeting the same SNP across populations could clarify these associations.

This review discusses existing forensic DNA phenotyping panels for biogeographical ancestry and externally visible characteristics and highlights major technical limitations, including terminology issues, genetic knowledge gaps, and technological debates; it reports no new results.

In this study, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

Forensic medicine is crucial for justice and needs continuous innovation and technology integration.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This study found that CD200-negative human hair follicle bulge cells have a higher hair-regenerative capability compared to CD200-positive cells, suggesting that reduced CD200 expression may enhance hair regeneration, providing insights for improving bulge cell-based hair restoration techniques.

This review highlights how the development of forensic DNA phenotyping systems like IrisPlex, HIrisPlex, and HIrisPlex-S has advanced criminal investigation by accurately predicting physical traits such as eye, hair, and skin color from DNA, thereby improving the precision and relevance of forensic applications.
