In addition, individuals harboring the RHC trait are predisposed to melanoma development. While <i>MC1R</i> variants have been established as causative of RHC and are a well-defined risk factor for melanoma, it remains unclear mechanistically why decreased MC1R signaling alters pigmentation and increases melanoma susceptibility. Here, we use single-cell RNA sequencing (scRNA-seq) of melanocytes isolated from RHC mouse models to define a MC1R-inhibited Gene Signature (MiGS) comprising a large set of previously unidentified genes which may be implicated in melanogenesis and oncogenic transformation. We show that one of the candidate MiGS genes, TBX3, a well-known anti-senescence transcription factor implicated in melanoma progression, binds both E-box and T-box elements to regulate genes associated with melanogenesis and senescence bypass. Our results provide key insights into further mechanisms by which melanocytes with reduced MC1R signaling may regulate pigmentation and offer new candidates of study toward understanding how individuals with the RHC phenotype are predisposed to melanoma.</p>","PeriodicalId":219,"journal":{"name":"Pigment Cell & Melanoma Research","volume":"37 2","pages":"291-308"},"PeriodicalIF":4.3,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/pcmr.13141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136395484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cytoglobin (CYGB), a ubiquitously expressed intracellular iron hexacoordinated globin, exhibits antioxidant activity and regulates the redox state of mammalian cells through its activities as peroxidase and nitric oxide (NO) dioxygenase. We postulated that CYGB functions in the melanogenic process as a regulator that maintains oxidative stress within a physiological level. This was examined by characterizing normal human melanocytes with the knockdown (KD) of <i>CYGB</i> using morphological and molecular biological criteria. <i>CYGB</i>-KD cells were larger, had more dendrites, and generated more melanin granules in the advanced stages of melanogenesis than control cells. The expression levels of major melanogenesis-associated genes and proteins were higher in <i>CYGB</i>-KD melanocytes than in wild type (WT) cells. As expected, <i>CYGB</i>-KD melanocytes generated more ROS and NO than WT cells.

The SMR was established in 2003 during the First International Melanoma Research Congress in Philadelphia. Meenhard Herlyn and Kate O'Neill were the driving force behind the inaugural SMR congress. Kate O'Neill wanted to honor the memory of her sister Noreen, who sadly lost her battle with melanoma. Four years earlier, Kate, Noreen, and Meenhard came together to establish the Noreen O'Neill Foundation for Melanoma Research, which served as the sponsor for the first SMR congress. They jointly envisioned a global community of basic scientists and clinicians sharing their expertise to combat one of the most challenging and deadly forms of cancer. Over the years this vision has become a reality, and a united community with almost 700 members has emerged. The SMR Congress brings together clinicians and scientists from diverse backgrounds to openly share their insights and latest research, and foster collective efforts aimed at battling melanoma.&lt;/p&gt;&lt;p&gt;The SMR has fostered numerous productive collaborations and nurtured the growth of rising talents. By promoting mentorship, exchange of knowledge and resources, and open discussions within the society's annual meetings, the SMR has supported the career of both junior and established researchers, as well as inspired the next generation of melanoma scientists.&lt;/p&gt;&lt;p&gt;In the past 20 years, groundbreaking discoveries and novel therapeutic approaches have shaped the landscape of melanoma treatment. From decoding the complexities of melanoma genetics, unraveling the intricate interactions within the tumor microenvironment, to developing immunotherapies that have revolutionized the treatment of melanoma, the collective efforts of the SMR community have brought us closer to conquering this challenging disease.&lt;/p&gt;&lt;p&gt;To mark the SMR's 20th Anniversary, some of our colleagues reflect on the past two decades, revisiting pivotal moments, landmark discoveries, and the evolution of our society. In this special issue of &lt;i&gt;PCMR&lt;/i&gt;, the contributing authors will take us through a journey, tracing the progress of the field under the SMR umbrella.&lt;/p&gt;&lt;p&gt;We sincerely thank our colleagues who have contributed to this special issue, and those who have been part of this journey—researchers, clinicians, trainees, patients, and advocates. The progress made is tangible proof of the power of collaboration, which has placed the melanoma field at the forefront of cancer research uncovering a therapeutic armamentarium that has revolutionized the clinical management of melanoma.&lt;/p&gt;&lt;p&gt;We invite you to join us in Philadelphia to celebrate the accomplishments of the field and the many melanoma researchers who have dedicated their careers to investigating and combating this challenging disease.

With this merger, the scope of manuscripts now published span the widest range of topics that include chemistry of melanin, vertebrate pigmentation, and pigmentary diseases to melanoma biology and clinical trials.

There are and will be many challenges to overcome. A journal is only as good as the quality of manuscripts it receives and the peer reviews of those manuscripts. Therefore, it is my sincere hope that the members of the pigment cell and melanoma community, bound together by our interest in this fascinating entity we call “melanocyte”, choose this journal as their first choice to submit and publish their best work and be ready and willing to serve as reviewers.
