Analysis of hsa_circ_0067934 expression in ESCC tissues and clinical parameters.
(A) hsa_circ_0067934 was detected in 51 pairs of ESCC tissues by qRT-PCR. The levels of hsa_circ_0067934 in ESCC tissues are significantly higher than those in non-tumor tissues (P = 0.011). Nucleic acid electrophoresis directly shows that hsa_circ_0067934 expression was upregulation in ESCC tumor tissues (The image below means the ESCC tumor tissue). Hsa_circ_0067934 was upregulated inpatients with poor differentiation and TNM III-IV stage. *P < 0.05. Error bars indicate S.E.M.
