In this study, researchers examined chicken feather follicle tissues from differently colored chickens and found that the genes SLC45A2 and GPNMB are involved in promoting melanin deposition, which enriches understanding of the genetic mechanisms affecting feather color.

This analysis reports that hepatitis B surface protein antigen exposure is associated with an increased risk of alopecia areata.

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.

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.

This preliminary study of Alopecia Areata identified limited expression of certain metabolic transporters and enzymes in hair follicle immune cells, providing early insight into their unique energy needs.

This review discusses the role of melanin synthesis in melanoma, focusing on how melanosomal pH might regulate melanin production, and reports no new results.

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.

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.

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 identified novel genetic associations with skin phenotypes such as age-spots, freckles, and hair characteristics in Japanese women, providing insights into the genetic basis of these traits.

This study identified the location of the genetic locus for the slick hair coat trait in cattle on bovine chromosome 20, which may contribute to heat tolerance.

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.

This review discusses genome-wide association studies in dermatology, noting that variants linked to risk for 10 skin complex diseases have been identified, with potential implications for diagnostics and management; it reports no new clinical results.

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 paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

This study investigated the genetic basis of coat color variation in cattle using skin transcriptome and whole-genome analyses, identifying the ASIP gene as a significant determinant that is differentially expressed and under strong positive selection in black and brown cattle breeds.

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.
