Background and purpose: The expression of growth factors, proteolytic enzymes, fibrogenic factors, and cytokines are altered in Helicobacter pylori (H. pylori) infected gastric mucosa. Matrix metalloproteinases (MMP) are a family of zinc-dependent homologous enzymes digesting most of the components of the extracellular matrix and basement membrane and are involved in remodeling and functioning of the biological processes. The purpose of this study was to compare gene expression of matrix metalloproteinase-7 (MMP-7) in patients with H. pylori-infected and uninfected individuals with gastrointestinal diseases.

Materials and methods: This study was conducted in 50 H. pylori-negative patients and 50 H. pylori-positive patients being admitted to Shahrekord Hajar Hospital due to gastrointestinal diseases in 2014. The participants’ demographic information was collected and sampling was done. First DNA was extracted, and then PCR was performed to check for the presence of 16sRNA and UreC. The RNA from each sample was also extracted and cDNA was prepared. Afterwards, the expression of MMP-7 was measured by real time-PCR using specific primers and probes.

Results: MMP-7 mRNA expression was significantly higher in biopsies of H. pylori-infected patients compared to that in H. pylori-uninfected patients (P<0.0001).

Conclusion: Increased expression of MMP-7 can be effective in inflammatory response and development of the disease. It could be used as a key marker for early diagnosis of gastrointestinal diseases and gastric cancer.
