Role of Biomarkers in the Integrated Management of Melanoma. DISEASE MARKERS 2022; 2021:6238317. [PMID: 35003391 PMCID: PMC8739586 DOI: 10.1155/2021/6238317] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 12/13/2021] [Indexed: 12/21/2022]
Abstract
Melanoma, which is an aggressive skin cancer, is currently the fifth and seventh most common cancer in men and women, respectively. The American Cancer Society reported that approximately 106,110 new cases of melanoma were diagnosed in the United States in 2021, with 7,180 people dying from the disease. This information could facilitate the early detection of possible metastatic lesions and the development of novel therapeutic techniques for melanoma. Additionally, early detection of malignant melanoma remains an objective of melanoma research. Recently, melanoma treatment has substantially improved, given the availability of targeted treatments and immunotherapy. These developments have highlighted the significance of identifying biomarkers for prognosis and predicting therapy response. Biomarkers included tissue protein expression, circulating DNA detection, and genetic alterations in cancer cells. Improved diagnostic and prognostic biomarkers are becoming increasingly relevant in melanoma treatment, with the development of newer and more targeted treatments. Here, the author discusses the aspects of biomarkers in the real-time management of patients with melanoma.

Inactivating p53 is essential for nerve growth factor receptor to promote melanoma-initiating cell-stemmed tumorigenesis. Cell Death Dis 2020; 11:550. [PMID: 32686661 PMCID: PMC7371866 DOI: 10.1038/s41419-020-02758-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Revised: 07/03/2020] [Accepted: 07/06/2020] [Indexed: 12/19/2022]
Abstract
Nerve growth factor receptor (NGFR, CD271, or p75NTR) is highly expressed in melanoma-initiating cells (MICs) and is critical for their proliferation and tumorigenesis, and yet the underlying mechanism(s) remain incompletely understood. We previously showed that NGFR inhibits p53 activity in a negative feedback manner in various cancer cells. Here we report that this feedback inhibition of p53 by NGFR plays an essential role in maintaining the sphere formation (stem-like phenotype) and proliferation of MICs, and in promoting MIC-derived melanoma growth in vivo. Knockdown of NGFR markedly reduced the size and number of spheroid formation of melanoma cells, which can be rescued by ectopically expressed NGFR. This reduction was also reversed by depleting p53. Consistently, knockdown of NGFR led to the suppression of MIC-derived xenograft tumor growth by inducing the p53 pathway. These results demonstrate that the NGFR-p53 feedback loop is essential for maintaining MIC stem-like phenotype and MIC-derived tumorigenesis, and further validates NGFR as a potential target for developing a molecule-based therapy against melanoma.

Melanoma types by in vivo reflectance confocal microscopy correlated with protein and molecular genetic alterations: A pilot study. Exp Dermatol 2019; 28:254-260.

Abstract
Cutaneous melanoma (CM) is one of the most prevalent skin cancers, which lacks both a prognostic marker and a specific and lasting treatment, due to the complexity of the disease and heterogeneity of patients. Reflectance confocal microscopy (RCM) in vivo analysis is a versatile approach offering immediate morphological information, enabling the identification of four primary cutaneous RCM CM types. Whether RCM CM types are associated with a specific protein and molecular genetic profiles at the tissue level remains unclear. The current pilot study was designed to identify potential correlations between RCM CM types and specific biological characteristics, combining immunohistochemistry (IHC) and molecular analyses. Eighty primary CMs evaluated at patient bedside with RCM (type 1 [19, 24%], type 2 [12, 15%], type 3 [7, 9%] and type 4 [42, 52%]) were retrospectively evaluated by IHC stains (CD271, CD20, CD31, cyclin D1), fluorescence in situ hybridization FISH for MYC gain and CDKN2A loss and molecular analysis for somatic mutations (BRAF, NRAS and KIT). RCM CM types correlated with markers of stemness property, density of intra-tumoral lymphocytic B infiltrate and cyclin D1 expression, while no significant association was found with blood vessel density nor molecular findings. RCM CM types show a different marker profile expression, suggestive of a progression and an increase in aggressiveness, according to RCM morphologies.

The interaction between SBA-15 derivative loaded with Ph 3Sn(CH 2) 6OH and human melanoma A375 cell line: uptake and stem phenotype loss. J Biol Inorg Chem 2019; 24:223-234. [PMID: 30759278 DOI: 10.1007/s00775-019-01640-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Accepted: 12/21/2018] [Indexed: 12/13/2022]
Abstract
Extraordinary progress in medicinal inorganic chemistry in the past few years led to the rational design of novel platinum compounds, as well as nonplatinum metal-based antitumor agents, including organotin compounds, whose activity is not based on unrepairable interaction with DNA. To overcome poor solubility and toxicity problems that limited the application of these compounds numerous delivering systems were used (Lila et al. in Biol Pharm Bull 37:206-211, 2014; Yue and Cao in Curr Cancer Drug Targets 16:480-488, 2016; Duan et al. in WIREs Nanomed Nanobiotechnol 8:776-791, 2016). Regarding high drug loading capacity, mesoporous silica nanoparticles like SBA-15 became more important for targeted drug delivery. In this study, cellular uptake and biological activities responsible for organotin(IV) compound Ph3Sn(CH2)6OH (Sn6) grafted into (3-chloropropyl)triethoxysilane functionalized SBA-15 (SBA-15p → SBA-15p|Sn6) were evaluated in human melanoma A375 cell line. Moreover, the influence of SBA-15p grafted with organotin(IV) compound on the stemness of A375 cell was tested. Given the fact that SBA-15p|Sn6 nanoparticles are nonspherical and relatively large, their internalization efficiently started even after 15 min with stable adhesion to the cell membrane. After only 2 h of incubation of A375 cells with SBA-15p|Sn6 passive fluid-phase uptake and macropinocytosis were observed. Inside of the cell, treatment with SBA-15p loaded with Sn6 promoted caspase-dependent apoptosis in parallel with senescence development. The subpopulation of cells expressing Schwann-like phenotype arose upon the treatment, while the signaling pathway responsible for maintenance of pluripotency and invasiveness, Wnt, Notch1, and Oct3/4 were modulated towards less aggressive signature. In summary, SBA-15p enhances the efficacy of free Sn6 compound through efficient uptake and well profiled intracellular response followed with decreased stem characteristics of highly invasive A375 melanoma cells.
