The spatially resolved transcriptome signatures of glomeruli in chronic kidney disease

Project description:Here, we used Digital Spatial Profiling (DSP) to describe the glomerular transcriptomic signatures that may characterize the complex molecular mechanisms underlying progressive kidney disease in Alport syndrome, focal segmental glomerulosclerosis, and membranous nephropathy. Our results revealed significant transcriptional heterogeneity among diseased glomeruli, and this analysis showed that histologically similar glomeruli manifested different transcriptional profiles. Using glomerular pathology scores to establish an axis of progression, we identified molecular pathways that progressively decreased with increasing pathology scores, including Signal Recognition Particle-dependent co-translational protein targeting to membrane and selenocysteine synthesis pathways. We also identified a distinct signature of upregulated and downregulated genes common to all the diseases investigated when compared to non-diseased tissue from nephrectomies. These analyses using DSP at the single glomerulus level could help to gain insight into the pathophysiology of kidney disease

High resolution spatially resolved transcriptomic atlas of kidney injury and repair by RNA hybridization-based in situ sequencing [ISS, Cartana]

Project description:Spatially resolved transcriptomics technologies allow for the measurement of gene expression in situ. We applied direct RNA hybridization-based in situ sequencing (ISS, Cartana) to compare male and female healthy mouse kidneys and the male kidneys injury and repair timecourse of ischemic reperfusion injury (IRI). A pre-selected panel of 200 genes were used to identify the dynamics of cell states and their spatial distributions during injury and repair. We developed a new computational pipeline, CellScopes, for the rapid analysis, multi-omic integration and visualization of spatially resolved transcriptomic datasets. The resulting atlas allowed us to resolve distinct kidney niches, dynamic alterations in cell state over the course of injury and repair and cell-cell interactions between leukocytes and kidney parenchyma. Projection of snRNA-seq dataset from the same injury and repair samples allowed us to impute the spatial localization of genes not directly measured by Cartana.

Transcriptome Analysis of Human Diabetic Kidney Disease (DKD Glomeruli vs. Control Glomeruli)

Project description:We identified 1,700 differentially expressed probesets in DKD glomeruli and 1,831 in diabetic tubuli; 330 probesets were commonly differentially expressed in both compartments. The canonical complement signaling pathway was determined to be statistically differentially regulated in both DKD glomeruli and tubuli and was associated with increased glomerulosclerosis even in an additional set of DKD samples. Affymetrix expression arrays were used to identify differentially regulated transcripts in 44 microdissected human kidney samples. Stringent statistical analysis using the Benjamini_Hochberg corrected 2-tailed t-test was used to identify differentially expressed transcripts in control and diseased glomeruli and tubuli. This Series includes DKD and control glomeruli samples.

Spatially resolved epigenomic profiling of single cells in complex tissues

Project description:The recent development of spatial omics enables single-cell profiling of the transcriptome and the 3D organization of the genome in a spatially resolved manner. A spatial epigenomics method would expand the repertoire of spatial omics tools and accelerate our understanding of the spatial regulation of cellular processes and tissue functions. Here, we developed an imaging approach for spatially resolved profiling of epigenetic modifications in single cells

LSAGE Library Human Renal Glomeruli

Project description:Glomeruli were isolated from the kidney of a 72 yo male patient. The kidney was surgically removed due to renal cell carcinoma. The glomeruli were isolated from uninvolved renal parenchyma. Histology (H&E) of glomeruli and interstitium was normal. Keywords: Kidney Subcompartment Glomeruli were isolated using the sieving technique in ice-cold PBS, followed by isolation of total RNA with RNeasy kit. RNA was judged intact by agarose gel electrophoresis. SAGE library was custom-synthesized by Genzyme Corportation.
