Table 7 Summary of differentiating urinary metabolites in WT and meprin βKO mice at 4- and 8-weeks post STZ with a 2 ≤ FC and/or 2 ≤ VIP. A variable importance in projection (VIP) score 2 ≤ are considered to have strong predictive value. Differentiating Urinary metabolites that are independent of meprin β expression (levels change in both WT and meprin βKO mice)

From: Meprin β metalloproteases associated with differential metabolite profiles in the plasma and urine of mice with type 1 diabetes and diabetic nephropathy
