(A) Matrix metalloproteinase 3 (MMP-3) expression in serum free culture media conditioned by interleukin (IL)-1β treated or H pylori infected AGS cells, as measured by non-reducing sodium dodecyl sulphate-polyacrylamide gel electrophoresis immunoblot analysis using MMP-3 specific monoclonal antibody. Lane M, cell culture medium alone; lane C, medium from untreated/uninfected AGS cells. (B) Densitometric analysis of immunoreactive bands. The blot is a representative replicate selected from three experiments.Hp, Helicobacter pylori; MOI, multiplicity of infection; RDU, relative densitometric units.
