The hsa_circ_0004674 expression in DXR-resistant OS tissues and cells. A Hsa_circ_0004674 expression in DXR-resistant and DXR-sensitive OS tissues was measured by qRT-PCR. B QRT-PCR was performed to detect hsa_circ_0004674 expression in DXR-resistant OS cells (U2OS_R and KHOS_R) and normal OS cells (U2OS and KHOS). C The formation diagram of hsa_circ_0004674 was shown, and its splicing site was verified by Sanger sequencing. D After amplified by divergent primers and convergent primers in cDNA and gDNA using qRT-PCR, the PCR productions were detected by agarose gel electrophoresis. E The stability of hsa_circ_0004674 was examined by RNase R assay. *P < 0.05
