Figure 6 indicates that message levels for cytosolic retinoic acid binding protein (CRABP) and fatty acid binding protein (FABP) were unchanged by diabetes in the renal cortex, but that substantially more FABP message (mean ΔCT = 8.9) was present in the renal cortex than CRABP message (mean ΔCT = 14.5). Here, CRABP1 is linked to diabetes mellitus.
