Next, the qPCR was conducted to analyze MDM2 expression in pancreatic carcinoma samples, indicating that a marked augmentation of MDM2 was presented in pancreatic carcinoma samples when in contrast with the adjacent samples and HPDE6-C7 cells (Figure 4A, 4B, p<0.01). This evidence concerns the gene MDM2 and exocrine pancreatic carcinoma.
