Integrated proteomics and transcriptomics profiling reveals distinct aspects of kidney stone related genes in calculi rats

We conducted a calculi rat model, applied for an integrated proteomic and transcriptomic analysis to characterize the distinct gene expression profiles in calculi oxalate stone formation and its related kidney injury. Six distinct gene clusters were identified according to the consistency of transcriptome and proteome. Gene Ontology and KEGG pathway enrichment was performed to analyze the functions of each sub-group differentially expressed genes. Results showed that the calculi rat kidney was increased expression of injured & apoptotic markers and immune-molecules, and decreased expression of solute carriers & transporters and many metabolic related factors. The present proteotranscriptomic study provided a data resource and new insights for better understanding of the pathogenesis of nephrolithiasis, will hopefully facilitate the future development of new strategies for the recurrence prevention and treatment in patients with kidney stone disease.
