Western blot assay further affirmed that α-MT and LV-pTZU-SLC6A14 treatment both markedly suppressed the expression of p-PI3K (P85), p-AKT, and p-mTOR; however, SLC6A14 overexpression considerably increased the protein level of p-PI3K (P85), p-AKT, and p-mTOR in GC cells (Figures 4(c)–4(f)). Here, SLC6A14 is linked to gastric cancer.
