Single-nucleus transcriptomic landscape of human glomerular diseases [Xenium]

ABSTRACT: Disease-specific similarities and differences in single-cell-level transcriptomic alterations in various glomerular diseases are necessary to understand the pathophysiology of kidney glomerular diseases. We analyzed single-nucleus RNA sequencing (snRNA-seq) data from 262,984 nuclei from kidney biopsy cores from 28 subjects with glomerular disease, including minimal change disease, membranous nephropathy, IgA nephropathy, and diabetic kidney disease and control individuals. Our findings revealed that the upregulated differentially expressed genes (DEGs) exhibited disease-specific and cell type-common patterns, and the downregulated DEGs exhibit cell type-specific and disease-common patterns across various cell types. Differences in the transcriptomic profiles of patients with each type of glomerular disease were identified with a distinct pattern of gene expression and the related biological pathways. We also identified specific cell subtypes, including transitional cells between podocytes and parietal epithelial cells, podocytes with endocytosis features, and myofibroblasts, that are associated with the clinical features of glomerular diseases. Overall, we identified transcriptional alterations specific to each cell type or disease subcategory and established a valuable resource for further research on human glomerular disease.

Gene expression in a conditionally immortalized mouse podocyte cell line

Project description:The specialized glomerular epithelial cell (podocyte) of the kidney is a complex cell that is often damaged in glomerular diseases. Study of this cell type is facilitated by an in vitro system of propagation of conditionally immortalized podocytes. Here, genes that are differentially expressed in this in vitro model of podocyte differentiation are evaluated. Conditionally immortalized undifferentiated mouse podocytes were cultured under permissive conditions at 33*C. Podocytes that were differentiated at the non-permissive conditions at 37*C were used for comparison.

In silico nano-dissection: defining cell type specificity at transcriptional level in human disease (glomeruli)

Project description:To identify genes with cell-lineage-specific expression not accessible by experimental micro-dissection, we developed a genome-scale iterative method, in-silico nano-dissection, which leverages high-throughput functional-genomics data from tissue homogenates using a machine-learning framework. This study applied nano-dissection to chronic kidney disease and identified transcripts specific to podocytes, key cells in the glomerular filter responsible for hereditary proteinuric syndromes and acquired CKD. In-silico prediction accuracy exceeded predictions derived from fluorescence-tagged-murine podocytes, identified genes recently implicated in hereditary glomerular disease and predicted genes significantly correlated with kidney function. The nano-dissection method is broadly applicable to define lineage specificity in many functional and disease contexts. We applied a machine-learning framework on high-throughput gene expression data from human kidney biopsy tissue homogenates and predict novel podocyte-specific genes. The prediction was validated by Human Protein Atlas at protein level. Prediction accuracy was compared with predictions derived from experimental approach using fluorescence-tagged-murine podocytes.

Podocyte degradomics - N-Degradomic Analysis Reveals a Proteolytic Network Processing the Podocyte Cytoskeleton

Project description:Regulated intracellular proteolysis is essential in maintaining the integrity of podocytes and the glomerular filtration barrier of the kidney. Altered proteolytic substrate turnover has been associated with various glomerular diseases ranging from diabetic nephropathy to focal and segmental glomerulosclerosis. However, thus far it has not been possible to systematically identify proteolytically cleaved proteins although some of the proteases have been characterized. Here we applied TAILS to map N-termini in the mouse glomeruli proteome and to determine and quantify N termini in podocyte cell cultures challenged with PAN.

Human iPSC derived glomeruli facilitate accurate modelling of podocytopathy

Project description:Podocytes are the highly specialised cells within the glomeruli of the kidney that maintain the filtration barrier by forming interdigitating foot processes and slit-diaphragms. Disruption to these features result in proteinuria. Studies into podocyte biology and disease has been hampered by a paucity of in vitro models of this non-proliferative cell type. Here we characterise sieved glomeruli from kidney organoids derived from human pluripotent stem cells. Compared to conditionally immortalised podocytes, organoid-derived glomeruli show superior podocyte-specific gene and protein expression, morphology and functional properties. Using CRISPR-derived MAFB reporter iPSC lines, homozygous MAFB mutant organoids recapitulated the anticipated disease related transcriptional changes. Culture of kidney organoids on chicken chorioallantoic membrane resulted in glomerular vascularisation, glomerular filtration barrier assembly, formation of slit diaphragms and fenestrated endothelial cells. This definitively demonstrates that human iPSC kidney organoid-derived glomeruli can serve as an accurate model of human podocytopathies and glomerular disease in vitro.

MYDGF Deficiency Exacerbates Mitotic Catastrophe of Podocytes in Glomerular Disease

Project description:Podocytes, highly differentiated glomerular epithelial cells, are essential for the maintenance of glomerular filtration barrier. Podocyte dysfunction in podocytes is a major determinant of proteinuric kidney disease. By RNA sequencing analysis in ADR-treated podocytes with or without MYDGF overexpression, we observed the significant changes of genes important in regulating cell cycle in podocytes with ADR treatment.
