Expression of Melatonin Synthesizing Enzymes in Helicobacter pylori Infected Gastric Mucosa

Figure 1

Mean relative level of arylalkylamine-N-acetyltransferase (AA-NAT) expression in antral and body gastric mucosa in healthy subjects (control, white bars) and subjects with asymptomatic (grey bars) and symptomatic (black bars) H. pylori infections as measured by real-time PCR. Error bars denote SD; 𝑛=30 for each group; ^∗𝑃<0.05, ^∗∗𝑃<0.01 compared with the control.
