Increased circ_0029803 expression was associated with the progression of CRC. A Circ_0029803 expression in CRC tissues and normal tissues was detected by qRT-PCR. B Circ_0029803 expression in CRC cell lines (HCT-116 and SW480) and NCM460 cell line was measured by qRT-PCR. C, D The level of circ_0029803 in cytoplasm and nuclear of HCT-116 and SW480 cells was checked by qRT-PCR. E, F QRT-PCR was used to examine the abundance of circ_0029803 and linear mRNA in CT-116 and SW480 cells treated with RNase R. G Kaplan-Meier survival curve was used to analyze the 5-year overall survival of CRC patients with high circ_0029803 expression or low circ_0029803 expression. *P<0.05
