In the current issue, two articles highlight the impact of melanocyte transcription factor (MITF) on melanoma development. In the first, Lister et al. reveal in vivo proof of MITF directly regulating tumor development in BRAF(V600E) melanomas. In the second, Sturm et al. present a clinical trial that emphasizes the importance of the recently discovered E318K MITF germline mutation in patients with multiple primary melanomas.

Melanogenesis, the biological process responsible for melanin synthesis, plays a crucial role in determining skin and hair color, photoprotection, and serving as a biomarker in various diseases. While various factors regulate melanogenesis, the role of fatty acids in this process remains underexplored. This study investigated the anti-melanogenic properties of 10(E)-pentadecenoic acid (10E-PDA) through both in silico and in vitro analyses.

Yet the differential roles and biological functions of co-targeting transcription factors is poorly understood. In melanoma, three highly-related transcription factors are co-expressed: The mTORC1-regulated TFEB and TFE3, that are key effectors of a wide range of metabolic and microenvironmental cues; and MITF, that controls melanoma phenotypic identity.

Recent findings by Abrahamian et al. (2024) provides new insights into the relationship between Two Pore Channel 2 (TPC2) activity and the development and progression of melanoma. Melanocyte inducing transcription factor (MITF) is a critical regulator of both melanocyte and melanoma behavior.

Background: Melanoma cells frequently dedifferentiate in response to inflammation which can increase responses to certain cytokines. Interferon-γ (IFNγ) is an integral part of the anti-tumor immune response and can directly induce both differentiational changes and expression of immunosuppressive proteins in melanoma cells. How the differentiation status of melanoma cells affects IFNγ responses remains unclear.

One important functional food ingredient today, valued for its health properties and ability to prevent disease, is bee pollen, which comprises a combination of nectar, pollen from plants, and the secretions of bees. In this research, the tyrosinase (TYR) inhibiting abilities of the peptides derived from bee pollen protein hydrolysates are investigated. Various proteases were utilized to generate these peptides, followed by testing at different concentrations.
