PTEN and gastric cancer: Furthermore, we co‐transfected pcDNA‐SLC25A5‐AS1 and miR‐19a‐3p mimics in GC cells, and found that SLC25A5‐AS1 partially could restore the protein levels of PTEN, p‐PI3K, p‐AKT, as compared with miR‐19a‐3p mimics transfected ones, whereas, the protein levels of PI3K, AKT had no change (Figure 7G).
