This study demonstrated that novel curcumin analogs CMC2.24, CMC2.23, and CMC2.5 were more effective and less toxic than parent curcumin in inhibiting melanin production in normally pigmented human melanocytes, suggesting potential for skin depigmentation therapies.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This study demonstrated that the biomimetic peptide PTP20 may help preserve hair pigmentation and reduce greying by enhancing melanocyte function and increasing melanin production in human hair follicles.

Some Greek melanoma patients have gene mutations linked to increased cancer risk, a new color feature helps diagnose melanoma, the incidence of a skin condition in the Netherlands is rare, and a gene possibly affects male-pattern baldness.

Immune cells boost stem cell activity in hairy moles, causing more hair growth.

This study found that in mice, the epidermal microenvironment reverses the oncogenic effects of GNAQQ209L in melanocytes, inhibiting their survival and proliferation through paracrine signals.

The document concludes that dermatology training and grading scales need to better represent dark-skinned individuals to improve diagnosis and assessment of skin conditions.

This study found that non-pigmented hair follicles have significantly lower expression of nucleotide excision repair genes, which may be associated with reduced melanin production capacity in these follicles.

This article discusses the interactions between keratinocytes and melanocytes in maintaining epidermal and hair follicle homeostasis, without reporting new experimental results.

This study found that betamethasone increased tyrosinase activity and melanin content in amelanotic melanocytes from human hair follicles, suggesting a potential mechanism for glucocorticoid treatment in vitiligo.

This study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

This study observed that different vitiligo lesions display varying repigmentation patterns, which are associated with the extent of depigmentation, sun exposure, lesion stage, and type of therapy used.

This study found that rice bran ash extract and orthosilicic acid both increased melanin synthesis and related protein expression in melanocytes, suggesting potential therapeutic use for melanin deficiency.

This article reviews drug-induced pigmentation and reports no new clinical findings, highlighting difficulty in confirming drug associations due to factors like delayed onset and polypharmacy.

This article discusses the role of neurohormones and neuropeptides in hair follicle pigmentation and outlines promising neuroendocrinological strategies to address greying and damage, but reports no new clinical results.

In this case study, a 25-year-old female with premature hair graying achieved over 90% conversion of gray hair to black hair after 5 months of treatment with a topical peptide solution and hair supplements.

This article reviews the diverse regulatory roles of alpha-melanocyte-stimulating hormone in skin biology, highlighting its potential involvement in maintaining tissue homeostasis and protecting against inflammation-induced DNA damage but reports no new clinical findings.

This study observed that nevus melanocytes do not exhibit signs of senescence, suggesting that their growth arrest is due to cell interactions and not directly caused by BRAF activation.

This study reported that a bioderived melanoidin/tannic acid nanocomplex forms a durable, antioxidant-active coating on hair fibers, providing enhanced UV protection and improving tensile resilience by suppressing oxidative stress and activating endogenous antioxidant pathways.

Vitamin B12 deficiency can cause skin darkening and white hair, but it's reversible.

This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

In this study, lower serum adiponectin levels and altered lipid profiles were observed in patients with periorbital melanosis, suggesting an association with metabolic syndrome.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

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 review summarizes current melasma treatments, emphasizing the need for tailored, long-term management strategies that integrate photoprotection and address various pathogenic mechanisms.

This study found that stem cell factor combined with fibronectin and type IV collagen promotes migration of amelanotic melanocytes, which may help explain their movement during vitiligo repigmentation.

This review summarizes the characteristics of the peri-malignant melanoma stroma, indicating its potential role in early dermal metastatic migration and increased metastasis risk.
