CircPVT1 was up-regulated in EC. a The circPVT1 expression level in blood samples was detected and there is no significant difference between EC patients and healthy people. P > 0.05; n = 20. b The circPVT1 was markedly up-regulated in EC tissues compared with the adjacent tissues. **P < 0.01; n = 20. c The level of circPVT1 was significantly increased in cancer cell lines, especially in EC109, TE-1 and TE-10. **P < 0.01; n = 3. d The circPVT1 levels decreased significantly when TE-1 cells were maintained to over-confluence. P < 0.01; n = 3. e The circPVT1 levels decreased significantly when EC109 cells were maintained to over-confluence. P < 0.01; n = 3. f The circPVT1 levels decreased significantly when TE-10 cells were maintained to over-confluence. P < 0.01; n = 3
