According to the study, low expression of LINC01550 is associated with shorter overall survival and disease-free survival of melanoma patients. Overexpression of LINC01550 can inhibit the proliferation and invasion abilities of melanoma cells.
Melanoma is a high-grade malignant subtype of human skin cancer with the highest mortality rate. Here we perform a bioinformatics analysis concerning human melanoma tissues by the Gene Expression Omnibus (GEO) database and Gene Expression Profiling Interactive Analysis (GEPIA) platform. We found that lncRNA LINC01550 was significantly down-regulated in the melanoma tissues as compared to the normal tissues. The low expression of LINC01550 was tightly associated with shorter overall survival and disease-free survival of patients with melanoma. LINC01550 expression is negatively associated with tumor cell proliferation and invasion abilities in melanoma as evidenced by the single-cell RNA sequencing (scRNA-seq) databases. LINC01550-overexpressing vectors were transferred into melanoma cells (WM35 and WM451). Up-regulation of LINC01550 significantly inhibited proliferation and invasion abilities, as well as induced cell apoptosis and G1 and S phase arrest of the melanoma cells. In conclusion, overexpression of LINC01550 may serve as a potential therapeutic target for melanoma.
