Project description:The aim of this study is to establish a comprehensive transcriptome atlas that enables identification of key molecular pathways and morphogenic events regulating postnatal renal medulla/papillary and cortex development. To achieve this, a microarray expression profiling was performed on postnatal day 0-90 renal medulla and cortex obtained from CD1 male mice.
Project description:The aim of this study is to establish a comprehensive transcriptome atlas that enables identification of key molecular pathways and morphogenic events regulating postnatal renal medulla/papillary and cortex development. To achieve this, a microarray expression profiling was performed on postnatal day 0-90 renal medulla and cortex obtained from CD1 male mice. Renal medulla and cortex were regionally dissected from postnatal day 0-90 CD1 male mice, and total RNA extracted for microarray expression profiling. Each time point consists of RNA pooled from 4 biological replicates, and an Agilent Bioanalyser test was performed to assess RNA integrity prior to sample pooling. The microarray data was analysed with the use of lumi and limma packages (Bioconductor) in R.
Project description:Comparison between renal papilla tissue with and without the presence of calcified Randall’s plaques, and between the papilla, medulla, and cortex regions from within a single recurrent stone forming kidney demonstrated that patterns of gene expression between the papilla, medulla, and cortex that distinguished these three regions from one another. Disease and function analysis of these gene sets demonstrated up-regulation of genes related to urinary/renal disorders, granulocyte response, vascular smooth muscle cell proliferation, dehydration, and renal calcification and down-regulation of genes related to carboxylic acid/ lipid/ fatty acid transport and urine osmolality.

Project description:Renal dendritic cells play key roles in renal homeostasis and during kidney allograft rejection. Microarray analysis aims to evaluate whether dendritic cells modulate their gene expression profile in relation to their distribution in the different renal compartments (with varying biophysical characteristics), under homeostatic conditions and during acute renal allograft rejection (3 days post-transplantation). Renal dendritic cells from homeostatic (healthy) kidneys and donor/host dendritic cells from renal allografts (3 days post-kidney transplantation) were isolated from cortex and medulla, through fluorescence-activated cell sorting (FACS). Total RNA was isolated from FACS-sorted cells and amplified. The cDNA product was fragmented, biotin-labeled and hybridized on Affimetrix arrays.
Project description:The renal medulla is a specialized region of the kidney with important homeostatic functions. It has also been implicated in genetic and developmental disorders and ischemic and drug-induced injuries. Despite its role in kidney function and disease, the medulla’s baseline gene expression and epigenomic signatures have not been well described in the adult human kidney. Here we generate and analyze gene expression (RNA-seq), chromatin accessibility (ATAC-seq), chromatin conformation (Hi-C) and digital spatial profiling data from adult human kidney cortex and medulla. Using data from our carefully annotated specimens, we assign samples in the larger public GTEx database to cortex and medulla, thereby identifying several misassignments and extracting meaningful medullary gene expression signatures. Using integrated analysis of gene expression, chromatin accessibility and conformation profiles, we reveal insights into medulla development and function. Our datasets will also provide a valuable resource for researchers in the GWAS community for functional annotation of genetic variants.
Project description:Here, we leveraged our recently described high-yield nuclei extraction method and performed Hi-C and Cleavage Under Targets and Release Using Nuclease (CUT&RUN) sequencing of histone modifications (H3K4me3 and H3K27me3) in parallel on the kidney cortex, medulla and papilla samples dissected from the same donor. This site describes the Hi-C data.
