VCAM1 and diabetic kidney disease: Of the 4 proteins selected for validation, we observed that CD14, lumican, and VCAM-1 are overexpressed in subsets characterizing diabetic nephropathy, focal segmental glomerulosclerosis, and lupus; however, our observed increases in HEXA urinary excretion was not reflected at the tissue level in Nephroseq as only two datasets reported significantly altered expression in opposing directions.
