Despite the fact that gelatinases involve in liver cirrhosis is provided in the literature, their role in the pathogenesis of chronic pancreatitis and non-specific inflammatory bowel diseases is still under investigation. DATA SOURCES： We carried out a PubMed search of Englishlanguage articles relevant to the involvement of gelatinases in the pathogenesis of liver fibrosis, pancreatitis, and non-specific inflammatory bowel diseases. RESULTS： The decreased activity of gelatinases, especially MMP-2, is related to the development of liver fibrosis, probably due to the decrease of capability for ECM remodeling. Similar situation can be found in chronic pancreatitis; however, reports on this matter are rare. The presence of non-specific inflammatory bowel diseases results in MMP-9 activity elevation. CONCLUSION： The fluctuation of gelatinases activity during liver fibrosis, chronic pancreatitis and non-specific inflammatory bowel diseases is observed, but the exact role of these enzymes demands further studies.展开更多
