CADM2 and gastric cancer: It was found that the levels of lncRNA CADM2-AS1 and NOTCH4 mRNA in GC tissues with lymph node metastasis were notably higher than that in tumor-adjacent tissues respectively (Figures 8A, B), while the level of miR-5047 in GC tissues with lymph node metastasis was lower than that in tumor-adjacent tissues (Figure 8C).
