In addition, the mRNA for the ECM remodeling enzyme MMP2 was significantly upregulated in the DM_CKD group compared to DM alone and with a trend towards upregulation vs WT, with no significant changes observed in MMP9 but a trend towards increased TIMP1 expression in DM_CKD vs WT as well as DM. This evidence concerns the gene TIMP1 and chronic kidney disease.
