This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

In this study, a combined regimen of an oral supplement with Pinus pinaster, Grape seed extract, vitamins, and minerals, plus high SPF sunscreen, significantly improved mild-to-moderate facial melasma in 30 women over 84 days, reducing pigmentation and enhancing cosmetic appearance with no reported adverse effects.

This study found that the pituitary gland is crucial for normal pelage color cycles in weasels, with certain hormones influencing regrowth of pigmented or white hair after molting.

This case report details the diagnosis of monilethrix in a 4-year-old boy, characterized by brittle hair and specific dermoscopic findings, and highlights the condition's hereditary nature and management through avoiding mechanical hair damage.

This study found that 18 mg melatonin implants did not significantly prevent recurrence of canine flank alopecia compared to placebo in dogs, though the treatment was well-tolerated, with no evidence of improved efficacy.

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

ACTH promotes hair growth in mink, but α-MSH does not.

This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

This study found that m6A-circHECA enhances the differentiation of stem cells into hair follicle lineages in cashmere goats by sequestering miR-449a-5p, boosting LEF1 gene expression, and activating the Wnt/β-catenin pathway.

This study explored using 3D models derived from reflectance confocal microscopy to better understand and differentiate melanoma on sun-damaged skin, suggesting enhanced diagnostic possibilities.

Recognizing minor skin lesions can help identify serious cancer syndromes.

In this study, a hair tonic containing black fungus extract was shown to have antifungal activity against Malassezia furfur, with the 70% extract concentration providing the strongest effect.

This study suggests that m6A-circHECA may influence the physiology of cashmere goats' SHFs both through miRNA pathways and interactions with target proteins, with promoter methylation potentially inhibiting its gene expression.

In an animal study, researchers found that a hair tonic containing a 1:1 ratio of kelor and rambutan leaf extracts led to similar hair growth in rabbits compared to a minoxidil control, with average hair lengths of 3 cm versus 2.025 cm, respectively.

This study found that α-melanocyte-stimulating hormone may modulate inflammation in skin connective tissue by inhibiting proinflammatory effects in fibroblasts.

This report documented the first known case of Malassezia slooffiae-associated dermatitis identified in a goat through diagnostic work-up, including histology and DNA sequencing.

Monilethrix involves multiple genes affecting hair structure, including DSG4 mutations.

This study reported that 39.7% of Amargosa voles had mite-associated lesions, which may severely impact their health and fitness.

This study suggests that different melanocyte subpopulations in hair follicles have varying patterns of apoptosis and survival during the catagen phase, which may inform models for modulating melanocyte behavior in vivo.

This study found that exogenous melatonin binds to the nuclear receptor RORα in Inner Mongolia cashmere goats, stimulating secondary hair follicle development and promoting villus growth.

This study identified significant differences in the fungal gut microbiota between melanoma and vitiligo patients compared to healthy controls and observed varying bacterial abundances associated with melanoma histopathology and vitiligo clinical parameters.

This study identified novel mutations in the DSG4 gene in a Japanese patient with monilethrix, affecting protein interactions that may disrupt hair shaft structure.

This study found that a more liberal intake of restricted amino acids in patients with methylmalonic acidemia resulted in improved growth and fewer illness episodes.

This study found that mycophenolate mofetil can enhance skin pigmentation in vitiligo models by activating the WNT signaling pathway and increasing melanin-related gene expression.

This article discusses mouse genetic studies to explore factors influencing melanogenesis, highlighting pH and cysteine's roles, and proposes a hypothesis for human hair color diversity; it reports no new results.

This research reports a new autosomal recessive mutation in mice, 'lanceolate hair', causing generalized alopecia and hair shaft abnormalities, which may serve as a model for Netherton's syndrome in humans.

The authors observed that the patterned melanoderma on the hairless scalp of fair-skinned Caucasian men with androgenic alopecia resembled similar patterns seen on facial skin.

This study found that α-melanocyte-stimulating hormone increased melanin production in hair follicles of moulting Siberian hamsters, whereas [8-arginine]-vasotocin inhibited melanin production without affecting tyrosinase activity.
