| Abstract | Background: Skin cutaneous melanoma (SKCM) is one of the most malignant tumors, and its incidence is increasing. Cuproptosis is a new type of programming cell death recently reported, which may play an important role in SKCM. Method: The mRNA expression data of melanoma were gathered from the TCGA and GEO databases. We constructed a prognostic model based on cuproptosis-related differential genes in SKCM. Finally, real-time quantitative PCR was performed to verify the expression of cuproptosis-related differential genes in patients with different stages of cutaneous melanoma. Results: We detected 767 cuproptosis-related differential genes based on 19 cuproptosis-related genes, and screened out 7 differential genes to construct a prognostic model, which including three high-risk differential genes (SNAI2, RAP1GAP, BCHE), and four low-risk differential genes (JSRP1, HAPLN3, HHEX, ERAP2). Kaplan-Meier analysis showed that SKCM patients with low-risk differential genes signals had a better prognosis. The KEGG results manifested that cuproptosis-related differential genes are mainly involved in T cell receptor signaling pathway, chemokine signaling pathway, natural killer cell mediated cytotoxicity, B cell receptor signaling pathway, T cell receptor signaling pathway. In our risk scoring model, the 1-year, 3-year and 5-year ROC values were 0.669, 0.669 and 0.685, respectively. Moreover, the tumor burden mutational and immunology function, cell stemness characteristics and drug sensitivity have significant differences in low-risk groups and high-risk groups. The mRNA expression level of SNAI2, RAP1GAP and BCHE in stage Ⅲ+Ⅳ SKCM patients was significantly higher than that in stage Ⅰ+Ⅱ patients, while the expression of JSRP1, HAPLN3, HHEX and ERAP2 in stage Ⅰ+Ⅱ SKCM patients was significantly higher than that in stage Ⅲ+Ⅳ SKCM patients. Conclusion: In summary, we suggest that cuproptosis may play an important role in regulating the tumor microenvironment and prognosis of SKCM patients, and may provide a theoretical basis for SKCM patients survival studies and clinical decision-making with potentially therapeutic drugs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
