Figure 3From: Dramatic early event in chronic allograft nephropathy: increased but not decreased expression of MMP-9 geneMMP mRNA expression in allografts and controls. Analyzed by densitometric comparison to β-actin (internal control) from the same sample after the positive image was digitized by video for computerized densitometry. The results were given as a ratio of the intensity of MMP-9 mRNA and β-actin mRNA. The expression MMP-9 mRNA was significantly increased in allografs compared to either F344 controls (P < 0.05) or LEW controls (P < 0.05).Back to article page
