Core Tip
Core tip: In this meta-analysis we looked at studies that investigated the relationship between Helicobacter pylori (H. pylori) and mucin expression in the human gastric mucosa. English Medical literature searches were conducted for studies comparing mucin expression in the gastric mucosa in patients positive and negative for H. pylori infection. Meta-analysis was performed, and pooled odds ratios were calculated compared mucin expression in individual studies. Eleven studies, which represent 53 sub studies of 15 different kinds of mucin, were found. H. pylori inhibited MUC5AC expression and facilitated colonization. In contrast, increased MUC6 expression may help inhibiting colonization, using MUC6 antibiotics properties.
