Elevated ZFAS1, APEX1, and declined miR-135a arefound in OS tissues. a Levels of ZFAS1, miR-135a, and APEX1 mRNA in OS tissues and normal tissues detected by RT-qPCR. b The protein band and expression of APEX1 in OS tissues and normal tissues. c The correlation analysis between ZFAS1 and miR-135a. d The correlation analysis between miR-135a and APEX1. Data in the figure were measurement data, in the form of mean ± standard deviation. * vs the normal tissue, P < 0.05
