RNA-SEQ analysis of various developing and adult kidney components

ABSTRACT: We used micro-dissection techniques and/or FACS to isolate cell types from the developing and adult kidney (E11.5 ureteric buds, E12.5, P1 and P4 cap mesenchyme, E15.5 collecting ducts, proximal tubules, ureter, Adult renal proximal tubules, podocytes, endothelial and mesangial cells). RNA-SEQ analysis was performed to determine the transcriptional profile of each cell type, identify component specific transcripts and isoforms and cell-type specific long-noncoding RNAs. In addition the unbiased nature of RNA-SEQ will potentially identify novel transcripts that have not been annotated in the database.

Total RNA is obtained from micro-dissected and/or FACS isolated embryonic and adult kidney components. The long term goal is to generate a transcriptional atlas of developing kidney.

The developmental programme for genesis of the entire kidney is recapitulated in Wilms tumour

Project description:Expression profiling of Wilms tumour samples, which identified molecular signatures of the ureteric bud and collecting duct as well as those of the proximal and distal tubules in triphasic histology tumours. These observations indicate Wilms tumours can arise from a precursor cell capable of generating the entire kidney, such as the cells of the intermediate mesoderm from which both the metanephric mesenchym and ureteric bud are derived.

Circadian Gene Expression in Mouse Renal Proximal Tubule

Project description:Circadian variability in kidney function has long been recognized but is often ignored as a potential confounding variable in in vivo physiological experiments. To provide a guide for physiological studies on the kidney proximal tubule, we have now created a data resource consisting of expression levels for all measurable mRNA transcripts in microdissected proximal tubule segments from mice as a function of the time of day. This approach employs small-sample RNA-sequencing (RNA-seq) applied to microdissected renal proximal tubules including both S1 proximal convoluted tubules (PCTs) and S2 proximal straight tubules (PSTs). The data were analyzed using JTK-Cycle to detect periodicity. The data are provided as a user-friendly web page at https://esbl.nhlbi.nih.gov/Databases/Circadian-Prox/. In PCTs, 234 transcripts were found to vary in a circadian manner (3.7 % of total quantified). In PSTs, 334 transcripts were found to vary in a circadian manner (5.3 % of total quantified). Transcripts previously known to be associated with corticosteroid action and transcripts associated with increased flow were found to be overrepresented among circadian transcripts peaking during the “dark” portion of the day (Zeitgeber 14-22), corresponding to the peak levels of corticosterone and glomerular filtration rate in mice.

Gene expression profiles of human mesangial cell line treated with and without ANGPT2

Project description:Glomerular diseases are the leading cause of chronic kidney diseases with pathomechanisms largely unclear. It is known that ANGPT2 regulates endothelial cell homeostasis and function via TEK/TIE2 and its deregulation causes endothelial damage. We found that ANGPT2 is upregulated in glomerular diseases and wondered whether it has any effect on glomerular podocytes and mesangial cells given that they have no or low TEK expression. We treated podocytes and mesangial cells in culture with ANGPT2 and found no overt cellular changes. RNA-seq analysis showed that gene expression was altered in both podocytes and mesangial cells and that the regulated genes in the two cell types were fundamentally different. GO and KEGG analyses showed that the two groups of regulated genes were enriched in distinct processes and pathways. These results suggest that ANGPT2 exerts effects on both podocytes and mesangial cells and that increased ANGPT2 may be involved in glomerular injury by affecting podocytes and mesangial cells in addition to endothelial cells.

Gene expression profiles in isolated proximal tubules and whole kidneys of rats after cisplatin-administration

Project description:To clarify the effects of cisplatin (cis-diamminedichloroplatinum II, CDDP) on the gene expression profiles in renal proximal tubules, microarray analyses were carried out using total RNA samples isolated from microdissected proximal tubules and whole kidneys. The molecular events underlying acute kidney injury (AKI) in the proximal tubules of rats with cisplatin-induced nephrotoxicity were successfully clarified with 17,000 transcripts. Renal proximal tubules were isolated under microscopy, and transcriptome data were collected with Rat Genome Survey MicroarrayÂ® (Applied Biosystems)

Cytokeratin 15 marks basal epithelia in developing ureters and is upregulated in a subset of urothelial transitional cell carcinomas

Project description:The mammalian ureter contains a water-tight epithelium surrounded by smooth muscle. Key molecules have been defined which regulate ureteric bud initiation and drive the differentiation of ureteric mesenchyme into peristaltic smooth muscle. Less is known about mechanisms underlying the developmental patterning of the multilayered epithelium characterising the mature ureter. In skin, which also contains a multilayered epithelium, cytokeratin 15 (CK15), an intermediate filament protein, is a marker for cells whose progeny contribute to epidermal regeneration following wounding. Moreover, CK15+ precursor cells in skin can give rise to basal cell carcinomas. In the current study, using transcriptome microarrays of embryonic wild type mouse ureters, we detected Krt15, coding for CK15.

Kidney on a Chip

Project description:<p>We generated primary cultures from mechanically isolated kidney glomeruli (filtration unit of the nephron) which are composed of podocytes and mesangial cells. In parallel, we generated primary kidney cortex tubule cell cultures, which are composed primarily of proximal tubule cells. Early passage cultures of these two cell types were subjected to chromatin accessibility profiling (DNase-Seq) and gene expression profiling (RNA-Seq). We found thousands of dynamically regulated enhancers in both cell types that potentially regulate nearby and distal target genes that are differentially expressed. These data will be useful for understanding the epigenomic regulation of gene transcription in key kidney cell types.</p>
