Figure 9. Expression of ULK1, ATG4A, and ATG5, and correlations with the Sox2OT-V7/miR-142/miR-22 axis in tissue samples. (A–C) The expression of ULK1, ATG4A, and ATG5 in 20 chemosensitive and 12 chemoresistant OS tissue samples was examined by qPCR. (D–J) The correlation of Sox2OT-V7, miR-142, miR-22, ULK1, ATG4A, and ATG5 was analyzed by Pearson’s correlation analysis. The data are presented as the mean ± SD of three independent experiments. *P<0.05, **P<0.01.
