Decreased type IV collagenase activity in experimental pancreatic fibrosis.


BACKGROUND Severe hyperstimulation and duct obstruction pancreatitis (SHOP) is characterized by pancreatic fibrosis and loss of acinar cell mass. MMP-2 and MMP-9 are type IV collagenases and gelatinases. We hypothesized that fibrosis results from disruption of the normal collagen homeostasis and that altered activity of the type IV collagenases may… (More)
