Furthermore, through screening of the miRNA expression chip GEO: GSE28955 of pancreatic cancer by R, among the three aforementioned miRNAs that targeted ADAM9, only hsa-miR-126-3p was poorly expressed in pancreatic cancer tissues (Figure 1I), suggesting that miR-126 could target ADAM9 in pancreatic cancer. The gene discussed is ADAM9; the disease is familial pancreatic carcinoma.
