MMP13 and inflammatory bowel disease: Subgroup analyses based on different anti-inflammatory agents applied in our IBD cohort revealed significantly decreased MMP-2, MMP-9, and MMP-13 gene transcripts in UC patients treated with corticosteroids compared to those with no corticosteroids in their therapeutic regime (MMP-2: 6.1-fold, p = 0.024; MMP-9: 4.2-fold, p = 0.009; MMP-13: 9.5-fold, p = 0.042).
