Mouse isolated kidney preglomerular arterioles: wild type vs conditional knockout of RBP-J in renin cells

ABSTRACT: mRNA profiling of mouse kidney preglomerular arterioles comparing wild type arterioles vs.arterioles from mice having deletion of RBP-J in cells of the renin lineage We used microarrays to detail the global program of gene expression in wild type and RBP-J conditional knockout (RPB-J cKO) kidney arterioles which revealed upregulation of genes that belong to the immune response system.

Uncovering the epigenomic determinants of kidney vascular development [scRNA-seq]

Project description:Renin cells are essential for survival. They control the morphogenesis of the kidney arterioles, and the composition and volume of our extracellular fluid, arterial blood pressure, tissue perfusion, and oxygen delivery. Renin cells and associated arteriolar cells descend from FoxD1+ progenitor cells. The chromatin states and transcription factors that determine the differentiation of these cells into those that compose the kidney vasculature are unknown. To answer these questions, we isolated progenitors and their descendants at different embryonic and postnatal stages, and using integrated scRNA-seq and scATAC-seq established the developmental trajectory that leads to the mosaic of cells that compose the kidney arterioles. We constructed a single-cell atlas of chromatin accessibility and gene expression profiles-including the critical transcription factors that determine the identity and fate of the mosaic of cells that occur during kidney vascular development. Furthermore, we identified the factors that determine the elusive, myo-endocrine adult renin-secreting juxtaglomerular cell.

Transcriptome analysis of human reninomas as an approach to understanding juxtaglomerular cell biology

Project description:Renin, a key component in the regulation of blood pressure in mammals, is produced by the rare and highly specialized juxtaglomerular (JG) cells of the kidney. Although these cells line the media of the glomerular afferent arterioles and share some characteristics with contractile cells, they are filled with lysosome-like organelles where renin is activated and stored for regulated secretion in response to physiological and pathophysiological stimuli. Chronic stimulation of renin release results in a recruitment of new JG cells by the seeming conversion of adjacent smooth muscle cells along the afferent arterioles. Because JG cells rapidly de-differentiate when removed from the kidney, their developmental origin and the mechanism that explains their phenotypic plasticity remain largely unclear. In an effort to overcome this limitation, we have performed RNA expression analysis on four human renin-producing tumors. The most highly expressed genes that were common between the reninomas were subsequently used for in situ hybridization in mouse kidney. Our results add 40 new genes to the list that characterize renin-producing cells and reveal a significant variation in the expression patterns of developing, mature and recruited JG cells.

Gene expression profiles of renin producing cells in the adult kidney (captopril treated animals) isolated from Renin-YFP transgenic mice using FACS (GUDMAP Series ID:46).

Project description:The long term objective is to create an encyclopedia of the expression levels of all genes in multiple components of the developing kidney. The central thesis is straightforward. The combination of fluorescent activated cell sorting (FACS) plus microarray analysis offers a powerful, efficient and effective method for the creation of a global gene expression atlas of the developing kidney. Microarrays with essentially complete genome coverage can be used to quantitate expression levels of every gene in FACS isolated components of the developing kidney. The ensuing rapid read-out provides an expression atlas that is more sensitive, more economical and more complete than would be possible by in situ hybridizations alone. Renin-YFP transgenic mice were utilized to isolate renin producing cells from the kidneys of Adult mice treated with captopril, which was provided in the drinking water at a concentration of 0.5mg/ml. In addition, mice were given low-salt chow. Mice were treated for two weeks before renin producing cells were isolated from the kidney by fluorescent activated cell sorting (FACS). RNA was isolated from FACS sorted cells and the gene expression profiles were determined by microarrays.

Transcriptomic analysis of Resp18mutant rat kidneys reveals up-regulation of Renin-Angiotensin system

Project description:Regulated endocrine specific protein 18 (Resp18), expression has been specifically located in a series of tissues and cell types however the exact cellular function is unknown. In previous studies we have showed that a targeted disruption of Resp18 in Dahl SS rats (Resp18mutant) resulted in higher blood pressure (BP), increased renal fibrosis, and decreased survival rate on a long term (6-week) 2% high salt (HS) diet treatment compared with wild type SS rats. In the current study we studied whether a short term (1 week) exposure to HS diet shows a similar effect in Resp18mutant rats. Furthermore, previously we have shown that in addition to BP phenotype Resp18mutant rats have demonstrated deteriorative kidney phenotype evident through renal fibrosis, protein urea and protein cast formation. Based on this background we conducted BP study and performed transcriptomic profiling of the kidney after one-week exposure to HS diet treatment. Through radio-telemetry procedure, we found that the systolic BP was increased in the Resp18mutant rats compared with SS rats even with short term HS diet exposure. Therefore, we sought out to investigate if there was any alteration in the transcriptomic response by HS diet treatment in the Resp18mutant rat kidneys. Using RNA sequencing approach, we found that Resp18mutant rats showed a differential expression of 25 genes of which one was an upregulation of Ren. We confirmed the upregulation of Ren and other differentially expressed genes via qRT-PCR analysis. Upon KEGG pathway enrichment we found that the Resp18mutant rat showed upregulation in the renin angiotensin system (RAAS), and renin secretion pathway. Furthermore, the renin activity is found to be higher in Resp18mutant rats serum compared with SS rats. Therefore, these observations demonstrate that upon disruption of Resp18 gene in SS rats associated with the increase in renin secretion and thus increase BP.

Transcriptome changes caused by RBP-L knockdown in rice grains

Project description:A T-DNA insertion within RBP-L 3’UTR resulted in 10-25% expression level of RBP-L gene compared to wild-type. The reduced expression of RBP-L caused partial mis-localization of glutelin and prolamine RNAs and conferred other general growth defects including dwarfism, late flowering and smaller seeds. Transcriptome analysis showed that RBP-L knockdown greatly affected the expression of prolamine family genes and many genes invovled in essential biological pathways during plant development.
