Serotonin-Exacerbated DSS-Induced Colitis Is Associated with Increase in MMP-3 and MMP-9 Expression in the Mouse Colon

Figure 3

5-HT alone increased MMP-3 and MMP-9 mRNA expressions in mouse colon. The treatment with low-dose 5-HT increased MMP-9 mRNA expression in mouse colon tissues; high dose only increased MMP-3 mRNA. Neither low- nor high-dose 5-HT increased the expression of MMP-2, TIMP-1, or TIMP-2 mRNA. Results are expressed as the mean ± standard deviations (SD) and 8 mice were included for all three groups. Multiple comparisons among group were done. versus control mice. versus 1 mg 5-HT group.
