Project description:This study examined large renal tubule extracellular vesicles (LRT-EVs) isolated from urine of a 5/6 nephrectomy (5/6Nx) rat model that recapitulates many elements of human chronic kidney disease (CKD). Within weeks of 5/6Nx rats spontaneously exhibit proximal tubular damage including brush boarder shedding and the production of LRT-EVs. Analysis of the LRT-EV size and a lack of TUNEL staining in 5/6Nx rats, suggested LRT-EVs to be distinct from exosomes, microvesicles, and apoptotic bodies.
Project description:Freshly isolated rat kidney proximal tubules were subjected for transcript profiling. Three microarray experiments were done to obtain the kidney proxmial tubule transcriptome.
Project description:Cultured cell lines are widely used for research in the physiology, pathophysiology, toxicology and pharmacology of the renal proximal tubule. The lines that are most appropriate for a given use depend on the genes expressed. New tools for transcriptomic and proteomic profiling using RNA-sequencing (RNA-Seq) and mass spectrometry make it possible to catalog expressed genes in each cell line. This data set is the protoemic data of Rat NRK-52E cell line. We concludeno cell line fully matched the transcriptome of native proximal tubule cells. However, some of the lines tested are suitable for the study of particular metabolic and transport processes seen in the proximal tubule.
Project description:In this study we have examined the effect of sub-cytotoxic exposure to aristolochic acids (1.65µM) at 6h, 24h and 72h on the whole-genome expression profile in a rat proximal renal tubule cell line (NRK-52E). We used microarrays to detail the mechanism of toxicity and possibly carcinogenicity of aristolochic acids in rat renal proximal cells.
