The Glomerulus Multi-Omics Analysis Provides Deeper Insights into Diabetic Nephropathy
Ontology highlight
ABSTRACT: Diabetic nephropathy (DN) is the leading cause of end-stage renal disease (ESRD), however, the detail mechanisms remain unclear. Here, we integrated the transcriptomics and proteomics profiles of glomeruli isolated from 50 biopsy-proven DN patients and 25 controls to explore the new discoveries underlying the pathogenesis of DN. First, 1,152 genes were differentially expressed at mRNA or protein level, and 364 of them showed strong correlation. Those strong correlated genes were divided into four different functional modules, including energy metabolism processes, extracellular matrix organization and cell adhesion, mRNA metabolism and protein translation, immune system and inflammation. In addition, a transcription factors (TFs) - target genes (TGs) regulatory network was constructed, among which 30 TFs up-regulated at protein levels and 265 downstream TGs were differentially expressed at the mRNA levels. Those TFs constitute the integration centers of different signal transduction pathways, and have great therapeutic potential in controlling the abnormal expression of TGs and the pathological process of DN. Furthermore, 29 new DN-specific splice-junction peptides with high confidence were identified, which may exert novel roles in the pathological progression of DN. So, our in-depth integrative transcriptomic-proteomic analysis provided deeper insights into the pathogenesis of DN and opened the potential avenue for finding new therapeutic interventions in DN.
