Circ_0007534 was highly expressed in CC tissues and cells. a, b The qRT-PCR was conducted to examine the significant upregulation of circ_0007534 expression in CC tissues compared to healthy tissues (a) and CC cell lines compared to normal cervical epithelial cell line (b). c, d The qRT-PCR after RNase R treatment affirmed that circ_0007534 was more stable than linear DDX42 in SiHa (c) and HeLa (d) cells. CC: cervical cancer, DDX42: DEAD box polypeptide 42. All assays were performed for three times with technical n = 3. Statistical analysis was conducted by Student’s t-test and one-way analysis of variance followed by Tukey’s test. *P < 0.05, **P < 0.01, ***P < 0.001
