Values for MMP-2, MMP-9 and proMMP-2 are given in units of picograms of enzyme per homogenized sample. Values for TIMP-1 and TIMP-2 are given as densitometry measurements of peak area per homogenized sample.
p: p values of differences in variables between each experimental group and control group; PA: significance of variable differences between all groups (one-way ANOVA); P2: significance of differences in variables between groups AT and EX (post-hoc Tuckey HSD test); P3: significance of differences in variables between groups AT and AT+EX (post-hoc Tuckey HSD test); P4: significance of differences in variables between groups EX and AT+EX (post-hoc Tuckey HSD test).
