ATG4D and non-small cell lung carcinoma: To elucidate the molecular mechanisms of miR-101-3p mediated autophagy, StarBase 3 (http://starbase.sysu.edu.cn/index.php) and TargetScan (http://www.targetscan.org/vert_71/) were used to analyze the expression of miRNA in NSCLC tissues and normal tissue or predicted the potential target genes of miRNA, and then found that ATG4D was a target gene for miR-101-3p (Figure 3a).
