This study suggests that melanoma tumor cells exhibit intrinsic plasticity, challenging the applicability of the cancer stem cell model to this malignancy.

This review discusses the impact of melatonin and its metabolites on skin aging, summarizing how they may serve as "aging neutralizers" through their anti-oxidative and anti-inflammatory properties, but reports no new clinical results.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This study found that female Holdobaggy goslings have higher melanin content in their dorsal plumage than males, suggesting that initial plumage color can be used for sex identification.

This study reveals that long non-coding RNAs influence cashmere fiber traits in goats by interacting with target genes involved in pathways affecting fiber diameter and color.

This study used single-cell techniques and lineage tracing to reveal that integrin α6 expression in neural crest cells can differentiate them into Schwann cells, melanocytes, and fibroblasts in skin, identifying integrin α6 as a potential marker for these derivatives.

This study examined aging hair follicle stem cells in mice and found that inflammation reduction in dermal white adipose tissue can stimulate regenerative behavior, highlighting its role in hair follicle aging.

This review examines the genetic factors influencing coat color in horses and donkeys, highlighting key genes like MC1R, TYR, MITF, ASIP, and KIT, and discusses implications for selective breeding and the relationship between coat color and specific equine diseases.

This review found that current forensic DNA phenotyping panels for biogeographical ancestry and visible traits face significant limitations due to inconsistencies in terminology, genetic understanding, and genotyping technologies, highlighting the need for harmonization and further research.

In this study, researchers identified key genes such as EDNRB2, GPNMB, TRPM1, TYR, and DCT that regulate melanin deposition in the breast muscles of black-boned chickens, contributing to their unique pigmentation during embryonic development.

Genetic studies on hair traits can improve understanding of health and disease.

This review discusses the role of zebrafish as a model for studying human hereditary pigmentary disorders and reports no new experimental results, emphasizing their genetic similarities and the genetic tools available.

This study found a significant overlap between gene expression signatures of alopecia areata and certain chronic inflammatory skin disorders, suggesting shared biological processes may drive their co-occurrence and providing a foundation for future research into distinct comorbid subtypes.

This study found that integrating machine learning enhances the predictive accuracy of forensic DNA phenotyping from low template DNA, achieving high accuracy for traits like eye color, although challenges remain for admixed populations and complex traits.

This review outlines evidence-based strategies for diagnosing pediatric hypopigmented disorders and emphasizes distinguishing vitiligo from self-limiting conditions through a systematic clinical approach; no new results are reported.

This review discusses forensic DNA phenotyping and its potential applications, particularly for human identification in Latin American populations, but notes challenges due to genetic diversity and reports no new results.

This study examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

This review explored the causes of hair graying and evaluated how plant-derived extracts and phytochemicals might alleviate it, noting that certain compounds showed potential in enhancing melanocyte function, reducing oxidative stress, and influencing stress-related pathways based on experimental evidence.

This review highlights the diverse roles of melanocytes in pigmentation, immunity, and hearing among other functions, their involvement in disorders, and their emerging potential in regenerative medicine, including applications in disease modeling and therapy development using advanced technologies.

This paper discusses forensic DNA phenotyping, emphasizing its ability to infer visible traits from biological samples without reference samples, but notes ethical and legal concerns related to its use.

In this study, two unrelated Honduran patients with Sjögren-Larsson syndrome had the same genetic mutation but displayed different disease severities, suggesting that factors beyond the ALDH3A2 mutation influence clinical outcome.

This case report highlights the use of microarray analysis to identify cryptic chromosomal rearrangements in a young woman with intellectual disability and multiple congenital anomalies.
