We then performed correlation analysis using Pearson's test, which showed a negative correlation between miR-106b/miR-93 and PTENP1/PTEN levels in the GC samples, suggesting a possible linkage of the PTENP1∼miR-106b/miR-93∼PTEN ceRNA network in vivo (Figure 6C–6F). This evidence concerns the gene PTEN and gastric cancer.
