Reconstruction of lncRNA-miRNA-mRNA network based on competitive endogenous RNA reveals functional lncRNAs in melanoma

Background: Melanoma is the most common and dangerous skin tumor, and its pathogenesis is not fully understood. Methods: To identify the key lncRNAs in melanoma, we reconstructed a global triple network based on the ceRNA theory. GO and KEGG pathway analysis were performed using DAVID. And, we verified our findings through qRT-PCR assay. Results: According to ceRNA theory, 898 DEMs,53 DELs and 16 DEMis were selected to reconstruct the ceRNA network. MALAT1, LINC00943, and LINC00261 were selected as hub gene in the ceRNA network. Conclusions: In this study, we found that MALAT1, LINC00943 and LINC00261 were closely associated with tumorigenesis and development of melanoma, and therefore, could be used as potential diagnostic biomarkers and therapeutic targets.
