Figure 1 confirms a decrease in the seric expression of miR-126 according to the CKD stage, as already described in Fourdinier et al. [6] using the same cohort with slightly different demographics. Figure 2 shows a clear correlation between eGFR and the four endothelial dysfunction markers evaluated in this study, i.e., Sdc-1, MMP-7, ANGPT2, and VCAM-1, confirming their value as biomarkers in this pathology. The gene discussed is MMP7; the disease is endothelial dysfunction.
