Abstract
AIM: To investigate the impact of Helicobacter pylori (H. pylori) infection on serum and gastric tissue levels of nucleobindin2 (NUCB2)/nesfatin-1 in humans.
METHODS: Serum and mucosal samples were collected from 83 asymptomatic volunteers who received gastroscopy and had H. pylori infection confirmed by 13C breath test, rapid urease test and Warth-Starry staining. The subjects were divided into an H. pylori positive group and an H. pylori negative group. Serum NUCB2/nesfatin-1 concentration was measured by enzyme-linked immunosorbent assay (ELISA) and the expression of NUCB2 mRNA in gastric mucosa was detected by real-time quantitative polymerase chain reaction.
RESULTS: Serum NUCB2/nesfatin-1 concentrations in the H. pylori positive and negative groups did not differ significantly (2.298 ng/mL ± 0.275 ng/mL vs 2.267 ng/mL ± 0.201 ng/mL, P > 0.05). The expression level of NUCB2 mRNA in the H. pylori positive group was significantly higher than that in the H. pylori negative group (1.336 ± 0.324 vs 0.914 ± 0.171, P < 0.01).
CONCLUSION: H. pylori infection induces the upregulation of NUCB2 mRNA in the gastric mucosa, but has no effect on serum NUCB2/nesfatin-1 concentration.
