Expression data indicated miR-337-3p mimics decreased STAT3 levels in AGS and BGC823 cells (Figure 5(d-e)), while, correlation analysis showed miR-337-3p expression was negatively correlated with STAT3 levels in GC tissue (Figure 5(f)), suggesting miR-337-3p targeted STAT3 in GC cells. The gene discussed is STAT3; the disease is gastric cancer.
