Fig. 2: Expression and characterization of circETFA in HCC.

A, B CircETFA expression was detected in the tumor tissues and plasma of HCC patients. C The patients were stratified into high and low circETFA groups using median circETFA value as a cutoff value. D Relationship between the expression of circETFA and the OS rate of HCC patients. E The area under the ROC curve of circETFA. F, G FISH and nucleoplasm separation experiment was performed to detect subcellular localization of circETFA in Hep3B. The data are shown as mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001.
