MMP inhibition in vivo. a Western blot analysis of MMP-2 and MMP-9 expression in tumors. b The activity of MMP-2 and MMP-9 measured by gelatin zymography. c Quantitative analysis of MMP activity from zymograms using a computer analysis program. Quantitative analysis of d MMP-2 and e MMP-9 expression. Glyceraldehyde 3-phosphate dehydrogenase (GADPH) was used as a loading control. Tumors used in these experiments were collected from 4T1 tumor-bearing Balb/C mice on day 19 after treatment (mean ± SD, n = 3, *p < 0.05)
