Project description:RNA-seq was performed to compare the transcriptome of three renin cell types: juxtaglomerular cells, cells isolated from chronically recruited mice and in As4.1 cells
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.
Project description:We generated genome-wide chromatin-state maps of mouse renin cells: chronically recruited cells and As4.1 cell line. We found that H3K27ac can discriminate a set of regulatory regions unique for the renin cells.
Project description:Four Kcng4-cre;stop-YFP mouse retinas from two mice were dissected, dissociated and FACS sorted, and single cell RNA-seq libraries were generated for 384 single cells using Smart-seq2. Aligned bam files are generated for 383 samples as one failed to align. Four mouse retinas (labeled 1la, 1Ra, and 2la, 2Ra respective from the two mice) were used, and 96 single cells from each were processed using Smart-seq2. Total 384 cells Smart-seq2 analysis of P17 FACS sorted retinal cells from the Kcng4-cre;stop-YFP mice (Kcng4tm1.1(cre)Jrs mice [Duan et al., Cell 158, 793-807, 2015] crossed to the cre-dependent reporter Thy1-stop-YFP Line#1 [Buffelli et al., Nature 424, 430-434, 2003])
Project description:This experiment was performed to study the expression profile of renin cells from mice subjected to homeostatic threat (hypotension). It was also used to compare expression of proliferation associated genes and tumor suppressors with existing cell line data.
