Figure 2. The expressions of circ_0081001, miR-494-3p, and BACH1 mRNA in OS samples and their correlations. (A–C) qRT-PCR was employed for assessing expressions of circ_0081001, miR-494-3p, and BACH1 mRNA in OS tissues and adjacent tissues. (D–F) The correlations amongst circ_0081001, miR-494-3p, and BACH1 mRNA in OS samples were analyzed by Pearson correlation analysis. ***P<0.001.
