Gelatin zymography showed that the group with the highest activity of MMP-9 expression was the IL-1α + plasminogen group (P < 0.05), sequentially followed by activity in the negative controls, IL-1α + plasminogen + L-UTI groups, IL-1α + plasminogen + H-UTI groups, L-UTI treatment groups, H-UTI, and GM6001 groups. This evidence concerns the gene IL1A and bacterial urinary tract infection.
