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

Table 9

The statistical results of mt2a gene expression with H. pylori infection and its virulence genes expression using Mann–Whitney U test. Fold changes of mt2a gene expression were calculated by using the average of mt2a ΔCt in the case and control groups ().
