Special Issue Information
Dear Colleagues,
In March 2022, our Special Issue "Melanoma: From Molecular Mechanisms to Therapeutic Opportunities" was launched (https://www.mdpi.com/journal/cells/special_issues/Melanoma_Molecular_Mechanism). Then, in June 2023, we published a second edition of this Special Issue (https://www.mdpi.com/journal/jcm/special_issues/EN152GA579).
Malignant melanoma remains a formidable challenge, with ~106,110 new cases and ~7180 deaths in the United States in 2021. Drug and immune resistance, together with invasion and metastasis, determine tumor progression, and, ultimately, patient survival. With the highest mortality rate among skin cancers, cutaneous melanoma is associated with driver mutations in MAPK and other signaling pathways, including RAS/PI3K/AKT, p16INK4a/CDK4/RB, WNT, and p53. Activating mutations are primarily found in the V600 or K601 of BRAF (50% of melanomas), Q61 of NRAS (>20%), and LOF mutations in NF1 (10%). Although combinations of targeted kinase inhibitors for BRAF and MEK, combined with immune checkpoint inhibitors, have improved progression-free and overall survival in melanoma patients, ~75% of melanomas recur after BRAF copy number gains, alternative splicing, MEK1/2, and NRAS gain-of-function mutations; 20% of BRAFi-resistant melanomas upregulate compensatory PI3K/AKT survival pathways. Although treatment for recalcitrant NRAS-mutant metastatic tumors has advanced, with immunotherapies anti–PD-1, anti-PD-L1, and/or anti-CTLA4 proving efficacious, many patients remain unresponsive, and chemotherapy with dacarbazine, temozolomide, or carboplatin shows limited success. There is a compelling rationale to examine unexploited pathways. Resistance has been attributed to subpopulations of “melanoma initiating cells”, highly tumorigenic cancer stem cells characterized by melanosphere formation, and the expression of specific cancer stem cell markers.
This Special Issue will publish original articles and reviews focusing on novel targets for therapeutic intervention; biomarkers for use in screening, predicting treatment response, and monitoring disease progression; and mechanistic insights and advances in molecular and cellular pathways involved in melanomagenesis and progression. Topics of interest include the mechanisms underlying melanoma progression and treatment response, signal transduction, melanoma-initiating cells, drug resistance, invasiveness, immune evasion, and metastasis. There is still an urgent need to identify novel targets and develop new combinatorial therapeutic approaches that can overcome drug resistance mechanisms.
Due to the success of the first two editions, we have decided to move forward with launching the third edition, with the aim of showcasing a range of original works. We are very keen to attract a global audience, and we welcome contributions on this subject from around the world, including both solicited and unsolicited submissions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
