Abstract
Circular RNAs (cicRNAs) have been identified to play pivotal roles in several cancer types. However, functions of circRNA in malignant melanoma are poor defined. Our current study demonstrated that human circMYC was obviously upregulated in human melanoma tissue. Furthermore, circMYC promoted the proliferation of human melanoma cells and Mel-CV cells. The expression of circMYC can repress Mel-CV cell glycolysis and LDHA activities in the in vitro glycolysis and lactate production evaluations. circMYC directly bound to miR-1236 as a molecular sponge that targeting miR-1236 in Mel-CV cells via bioinformatics analysis, pull-down assay, and luciferase reporter assays. Our present study revealed that 3′ UTR of LDHA acted as a target of miR-1236 using Mel-CV cells. Based on our findings, c-MYC-SRSF1 axis may regulate the production of circMYC. Overall, these results elucidate potential effects of circMYC in melanoma development and provide a promising biomarker for melanoma diagnosis.
