More importantly, the qRT-PCR results and IHC score revealed that the correlations between miR-509-3-5P and PODXL were negative in fresh GC and paraffin-embedded GC tissues (Figure 5D, 5E and 5F), which further indicated that miR-509-3-5P could negatively regulate PODXL expression via directly binding to its 3′UTR. Here, PODXL is linked to gastric cancer.
