Overexpressed circPVT1 in oral squamous cell carcinoma promotes proliferation by serving as a miRNA sponge

Circular RNAs (circRNAs) comprise a novel class of widespread non‑coding RNAs that may regulate gene expression in eukaryotes. However, the characterization and function of circRNAs remain elusive in human cancer, including oral squamous cell carcinoma (OSCC). In this study, the expression level of circPVT1 in OSCC was detected and define its functional role in initiation and progression of OSCC. It was identified that circPVT1 was upregulated...
