pubmed:abstractText |
Treatment of human uterine cervical fibroblasts with commercial lipopolysaccharide (LPS) preparations from different serotypes of Escherichia coli effectively augmented the processing of mammalian progelatinase A/promatrix metalloproteinase (proMMP)-2 to a 62-kDa form of MMP-2. When purified proMMP-2 was incubated with LPS preparations, the proenzyme was similarly processed into the 62-kDa active MMP-2 in a time- and dose-dependent manner. By contrast, progelatinase B/proMMP-9 and prostromelysin 1/proMMP-3 were not activated. A serine proteinase inhibitor, phenylmethylsulfonyl fluoride, completely interfered with this LPS-mediated activation of proMMP-2. This is novel evidence that E. coli serine proteinase is a specific activator of proMMP-2. Thus, it is very likely that E. coli infection plays a crucial role in the degradation of connective tissues via the activation of proMMP-2, and the resultant active MMP-2 participates in the dysfunction of connective tissues such as in the preterm rupture of fetal membranes.
