ptk2 and mt2a Genes Expression in Gastritis and Gastric Cancer Patients with Helicobacter pylori Infection

Table 8

The statistical relationships of ptk2 genes expression with H. pylori infection and its virulence genes expression using Mann–Whitney U test. Fold changes of ptk2 gene expression were calculated by using the average of ptk2 ΔCt in the case and control groups ().
