Correlation of expression of the candidate genes were obtained in comparison to the snRNA datasets, except that of CTGF which had a contradictory under expression in diabetic nephropathy Thus, the identified key candidate genes - FN1, SPARC, VCAN, LUM, POSTN, KNG1 and PTPRO can be considered further for the investigation in clinical research. This evidence concerns the gene LUM and diabetic kidney disease.
