Figure 1.

Expression of hsa_circ_0007534 was upregulated in tumor tissues from CRC patients. Hsa_circ_0007534 expression was measured in 112 pairs of tumor tissue and matched adjacent non-tumorous tissues from CRC patients, and the fold change was calculated (A). Hsa_circ_0007534 expression was measured in plasma from 112 CRC patients and 46 healthy controls (B). Hsa_circ_0007534 expression levels were measured with T classifications (C), N classifications (D), metastatic phenotype (E) and poor differentiation (F) in CRC patients. T, tumor tissues; N, non-tumorous tissues; HC, healthy control; M, moderate; P, poor. *P < 0.05, **P < 0.01, ***P < 0.001.
