Transcriptome profiling of USP40-silenced mouse podocytes

ABSTRACT: USP40 is a deubiquitinating enzyme implicated in podocyte cytoskeletal organization and cellular homeostasis. To investigate the transcriptional consequences of USP40 depletion, conditionally immortalized mouse podocytes were transfected with two independent USP40-targeting siRNAs (siRNA#1 and siRNA#2) or a non-targeting control siRNA. Three independent biological replicates were prepared for each condition. Total RNA was extracted 48 hours after transfection, followed by poly(A)+ RNA enrichment and strand-specific library preparation. Paired-end RNA sequencing (2 × 36 bp) was performed on an Illumina NextSeq 500 platform, generating two FASTQ files (R1 and R2) per sample. Sequence reads were aligned to the Mus musculus reference genome (GRCm39), and gene-level raw read counts were generated. Differential expression analysis was conducted using DESeq2, and genes with adjusted p-value < 0.1 and |log2 fold change| > 0.3 were considered differentially expressed. To ensure biological robustness, downstream analyses focused on genes commonly altered in both independent siRNA-mediated knockdowns. This dataset provides insight into USP40-dependent transcriptional reprogramming toward an injury-prone, cytoskeleton-remodeling state in podocytes.

Differentiated mouse podocytes (SVI)

Project description:Transcriptomes of differentiated cells of the conditionally immortalized mouse podocyte cell line SVI (Schiwek et al., Kidney Int. 66: 91-101, 2004) were determined as described in Kabgani et al. (PLoS One 7:e34907, 2012). The transcriptomes of the podocyte cell line were mapped on a protein-protein interaction network of the podocyte (PodNet). Together with other transcriptomes taken from GEO, we analyzed differential gene regulation and differential regulation of protein-protein interactions between cultured podocytes and differentiated in vivo podocytes. Three independent batches were used.

small RNA-seq of Extraceullular Vesicles derived from human immortalized podocytes treated with glucose and RabGTPase silenced

Project description:Diabetic nephropathy (DN) is a major cause of end-stage renal disease and is characterized by early podocyte injury, leading to progressive glomerular dysfunction. Increasing evidence highlights extracellular vesicles (EVs) as crucial mediators of intercellular communication in the diabetic kidney, transferring bioactive molecules such as non-coding RNAs (ncRNAs) that modulate cellular responses and contribute to disease progression. The molecular mechanisms governing the selective packaging of ncRNAs into podocyte-derived EVs under hyperglycaemic stress, as well as the role of vesicle trafficking regulators such as RAB GTPases, remain poorly understood. In this study, conditionally immortalized human podocytes were exposed to high glucose conditions to model the diabetic environment. To investigate the contribution of vesicular trafficking to EV release, the small GTPases RAB27A and RAB3A were silenced using siRNA. EVs were isolated and their small RNA content was profiled by next-generation sequencing followed by RT-qPCR validation. The results demonstrated that both hyperglycaemia and RAB GTPase knockdown significantly modified the ncRNA composition of podocyte-derived EVs, indicating that glucose stress and vesicular trafficking pathways jointly shape the extracellular RNA landscape. These findings provide new insights into how RAB GTPase–dependent mechanisms regulate EV-mediated communication in podocytes during diabetic injury, potentially influencing key signaling pathways involved in disease progression.

Deep RNA Sequencing of native mouse podocytes and non-podocytes glomerular cells

Project description:Purpose: Next-generation sequencing (NGS) was used to define the transcriptome of native mouse podocytes and non-podocytes glomerular cells as part of a project aiming to define the molecular fingerprint of mouse podocytes. Method: Glomeruli from 29 Gt(ROSA)26Sortm4(ACTB-tdTomato,-EGFP)Luo/J x hNPHS2Cre mice at the age of 10 weeks were purified and a single cell solution was prepared to seperate GFP-expressing (podocytes) and GFP-negative (non-podocytes glomerular cells) cells by FACS sorting. RNA was extracted and prepared for further analysis using directional, polyA+ library preparation. An Illumina HiSeq2500 was used for a paired-end sequencing of 100 cycles . Salmon and Sleuth were used for downstream analysis. Results: A total of 100 Million reads each from podocytes and non-podocytes glomerular cells could be used for further analysis.

Transcriptome profiling of NUP133 WT and KO podocytes

Project description:We generated NUP133 WT and KO podocytes to model human hereditary SRNS in vitro. A subtype of SRNS is caused by monogenetic mutations of the nuclear pore complex including NUP133. Immortalized human podocytes were genome edited applying the CRISPR/Cas9 technique and two independent NUP133 sgRNAs. Two monoclonal cell backgrounds were used to create two matching sets of NUP133 WT and KO cells (WT-1 versus KO-1 and WT-2 versus KO-2). Transcriptome profiling (RNA-Sequencing) and differential gene expression analysis was performed in duplicate for each cell line. NUP133 KO podocytes exhibit vast transcriptional changes compared to WT cells.

Mechanical stress enhances CD9 expression in cultured podocytes

Project description:Transcriptomes of differentiated cells of the conditionally immortalized mouse podocyte cell line SVI (Schiwek et al., Kidney Int. 66: 91-101, 2004) were determined as described in Warsow et al. (Kidney Int. 84: 104-115, 2013) after application of mechanical stress (Endlich et al., J. Am. Soc. Nephrol. 12: 413-422, 2001) as compared to control conditions. Elevated glomerular pressure represents a high risk for the development of severe kidney diseases and causes an increase of mechanical load to podocytes. In this study we investigated whether mechanical stress alters gene expression in cultured podocytes using gene arrays. We found that tetraspanin CD9 is significantly upregulated in cultured podocytes after mechanical stress. The differential expression of CD9 was confirmed by RT-PCR and Western blot under stretched and unstretched conditions. Furthermore, mechanical stress resulted in a relocalization of CD9. To get an insight into the functional role of CD9, podocytes were transfected with pEGFP-CD9. The expression of CD9 induced the formation of substratum-attached thin arborized protrusions (TAPs). Ca2+ depletion revealed that podocytes over-expressing CD9 possess altered adhesive properties in contrast to the control transfected cells. Finally, elevated CD9 expression increased migration of podocytes in a wound assay. In summary, our results suggest that upregulation of CD9 may play an important role in podocyte morphology, adhesion and migration. Three independent batches were used.

Gene expression profiling of human iPS cell-derived podocytes and sorted human adult podocytes

Project description:Podocytes play an important filtration role in the kidney. We examined culture condition for efficient podocyte induction and established a method to selectively induce podocytes from human iPS cells. To understand how expression profiles of human iPS cell-derived podocytes were close to that in vivo, we isolated human adult podocytes for human adult kidney. Purified RNAs from human iPS cells, nephron progenitor cells, human immortalized podocyte cell line, human iPS cell-derived podocytes, and sorted human adult podocytes were analyzed by RNA-seq.

Gene expression profiling of FOXP1-silenced diffuse large B-cell lymphoma (DLBCL) cell lines

Project description:To identify differentially expressed genes regulated by FOXP1 in DLBCL cells via gene expression profiling of GCB-DLBCL (DB, K422) and ABC-DLBCL (OCI-Ly3, HBL-1) cell lines treated with siRNA targeting FOXP1 or non-silencing siRNA control. Two GCB-DLBCL (DB, K422) and two ABC-DLBCL (OCI-Ly3, HBL-1) cell lines were each treated separately with two independent siRNA oligonucleotides targeting FOXP1 (siFOXP1_308, siFOXP1_309) or non-silencing siRNA (siCtrl). Biological replicates derived from three independent experiments were obtained, RNA-extracted and subsequently hybridized into a human microarray platform for gene expression profiling.
