This study describes a newly identified mite species, Demodex zalophi, found on captive sea lions and highlights its unique traits, including being the first of its kind described in marine mammals.

This study demonstrates that melanocyte stem cells can be a source of melanoma in a mouse model, resembling human melanoma in both heterogeneity and gene signatures.

In this study, researchers used single-cell RNA sequencing to define and locate three distinct cell states of melanocytes in mouse skin development, potentially aiding the understanding of abnormal melanocyte differentiation.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This study observed that fetal hair follicle melanocytes varied in morphology and development stages, with melanosomes undergoing degradation into irregular pigment particles within keratinocytes.

This study demonstrated that human iPSC-derived melanocytes, when transplanted into mice, can reconstitute pigmented hair follicles and integrate into normal tissue, suggesting their potential as a cellular therapy for depigmentation.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

This review explores the potential of microneedling as a drug delivery system for treating melasma, focusing on its mechanisms, safety, efficacy, and clinical advantages over conventional therapies like hydroquinone and lasers.

In this study, melatonin implants advanced and synchronized spring hair growth in goats by initiating fiber growth earlier than in untreated goats, with associated suppression of normal prolactin rise.

This article reviews how photoperiod, melatonin, and prolactin influence moult timing in mammals, focusing on cashmere goats, but reports no new experimental findings.

Alpha-MSH affects mitochondrial function, and MC1R mutations may increase skin aging.

This study suggests that BLMP-1 is important for timely molting and oscillatory gene expression in C. elegans, indicating a potentially conserved mechanism for rhythmic skin regeneration.

The study found that melatonin treatment in early postnatal cashmere goats increased both the quantity and quality of cashmere by promoting secondary hair follicle development and enhancing antioxidant enzyme activities.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This study found that both oral tranexamic acid and microneedling improve melasma treatment outcomes when added to standard therapy, with microneedling showing a more sustained remission.

This study found that ethyl acetate extract of Musa × pardisiaca L. leaves showed anticancer activity against cervical carcinoma and malignant melanoma in vitro.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

This study demonstrated that the FER/MLO signaling module regulates calcium dynamics and ROS accumulation in root hair growth, with the constitutively active MLO (faNTA) able to restore normal development and signaling in specific mutant genotypes, highlighting MLO15's role in root hair tip growth regulation.

This study found that gene expression patterns can effectively distinguish the cashmere growth cycle stages and highlight molecular pathways, suggesting melatonin's role in regulating cashmere growth in Inner Mongolian goats.

Advanced imaging techniques are crucial for accurately diagnosing Monilethrix, a rare hair disorder.

In this study, researchers found that exosomes derived from Pinctada martensii mucus can effectively inhibit melanin production in melanoma cells and zebrafish without adverse effects, potentially offering a promising therapeutic strategy for treating pigmentary disorders by modulating the NF-κB signaling pathway.

This study found that Malassezia pachydermatis was present on both lesion and healthy skin in a California sea lion, with significantly more colonies on the lesion site.

This review explores the multifaceted roles of melanocytes in skin biology, emphasizing their potential impact on future research to prevent and treat skin diseases, but reports no new experimental results.

This study investigated a spontaneous mutation in mice resulting in hair abnormalities and elevated IgE levels, which resembles human Netherton's syndrome and monilethrix.

This study identified a mutation hotspot in the caracul (Ca) locus of mice, implicating the mK6irs1/Krt2-6g gene in hair formation and potentially human hair and skin diseases.

This study found that myristoleic acid promotes dermal papilla cell proliferation and anagen signaling through autophagy, cell cycle progression, and activation of the Wnt/β-catenin and ERK pathways.

This study reports that lower levels of N-myc mRNA are observed when hair growth ceases in certain phases in mice, and attempts to create transgenic mice for further investigation resulted in high embryonic mortality.

This case report describes an adult female with concurrent mycosis fungoides and papillary dermal elastolysis, highlighting the importance of considering rare presentations in differential diagnoses.
