CDKN3 and gastric carcinoma: There were high significant (p<0.001) elevations in AADAC gene expression and CDKN3 gene expression in the gastric carcinoma group expressed by (M±SD) [(0.89±0.124), and (0.80±0.09)] compared to the corresponding values in the control group [(0.41±0.04), and (0.43±0.126) respectively] while PLEKHS1 gene expression showed a high significant (p<0.001) decrease in the gastric carcinoma group (1.68±0.31) compared to the corresponding values in the control group (2.70±0.17) as shown in Fig 1.
