RNAseq transcriptome analysis of THP-1 macrophages activated by VHL-deficient kidney tubule cells

Project description:Clear-cell renal cell carcinoma (ccRCC) is the most prevalent subtype of renal cell carcinoma (up-to 70% of all RCC types). There is a very close causal correlation between ccRCC and inactivation of the tumor suppressor gene von Hippel-Lindau (VHL) located on chromosome 3p25‐26. Up to 80% of sporadic ccRCC carry genomic mutations or epigenetic inactivation of VHL and nearly 100% familial ccRCC (in VHL disease) contain VHL deficiency. Accumulating evidence has indicated that ccRCC arises at the site of chronic inflammation and this solid tumor contains a substantial number of infiltrated immune cells. This indicates that ccRCC may be induced by the interaction between kidney tubule cells carrying inactivated VHL gene and the inflammatory microenvironment. In this study we characterized the interaction between VHL-deficient kidney tubule cells and macrophages with relevance to ccRCC formation, and found that human macrophages induced by VHL-deficient kidney tubule cells exhibit distinct gene expression program containing the signatures of tumor-associated macrophages that can promote ccRCC progression.

Effect of deletion of von-Hippel-Lindau (VHL) in the proximal tubule in diabetic kidney disease

Project description:To establish the role of proximal tubular hypoxia in diabetic kidney disease, we use a mouse line with a specific deletion of von-Hippel-Lindau (VHL) in the proximal tubule and treat them with streptozotocin (STZ) to induce a type I diabetes mellitus. 10 weeks after induction of diabetes mellitus samples were collected.

Transcriptome changes of whole kidney from conditional Vhl gene knockout in sub-populations of mouse kidney tubule cells

Project description:We are studying a tumor suppressor gene, von Hippel-Lindau (VHL). In humans, VHL mutations cause renal cell carcinoma of the clear cell type (ccRCC). We have generated a knockout mouse strain in which mouse Vhl is conditionally deleted in the kidney epithelium (that is, a subset of tubules including collecting ducts and ascending loop of Henle). Instead of ccRCC, these mice developed severe inflammation and fibrosis, accompanied by hyperplasia and the appearance of transformed clear cells. These phenotypes therefore support the notion that inflammation is the tissue precondition of cancer. Our hypothesis is that VHL loss-of-function-induced inflammation contribute to the initiation of carcinogenesis, through a mechanism that we want to determine. The aim of the microarray is to identify genes involved in the overgrowth of the epithelium, as well as in inflammation and fibrosis that may be important for ccRCC initiation.

Effect of GW4064 on primary cultured mouse kidney proximal tubule cells

Project description:Global gene expression in the primary cultured mouse kidney proximal tubule cells treated either DMSO or 1uM GW4064 (a FXR agonist) was compared. Results provide insight into mechanisms underlying effects of FXR activation on gene expression in mouse kidney proximal tubule cells. Male C57/BJ mice aged 6 weeks were sacrificed under anesthesia and kidney proximal tubule cells were cultured until confluent. Cells were treated with either GW4064 (1uM) or equal amount of DMSO and incubated for 24 hours. 4 total RNA samples per group were analyzed and gene expression was compared between the groups.

Microarray characterization of Vhl; Vhl, Hif1a; Vhl, Hif2a and Vhl, Hif1a, Hif2a deficient primary kidney cells

Project description:To unravel the potential cooperative roles of oxygen-regulated signaling pathways; von Hippel-Lindau (VHL) tumor suppressor protein and hypoxia-inducible factor (HIF) transcription factors, we have generated mutant mice with; Vhlh, Vhlh/Hif1Î±, Vhlh/Hif2Î± and Vhlh/Hif1Î±/Hif2Î± gene alleles floxed. Subsequently primary kidney cells were isolated, cultured and infected with Adenoviruses bearing either Cre/GFP or GFP expression only. Agilent cDNA microarrays were utilized to compare the gene expression profiles of the kidney epithelial cells from aforementioned cell cultures to gain insight about the molecules and signaling pathways that drive aberrant cellular proliferation in clear cell renal cell carcinoma (ccRCC). 24 independent biological samples from 4 genetic experimental conditions were hybridized in two- color format on 13 Mouse GE 4x44K v2 Microarray Kit (Design ID 026655) arrays. Eventual dye specific hybridization effects were controlled with dye swap on biological replicates. For an each experimental condition 3 arrays were use, except of one where 4 arrays were used (one sample combination in repetition with a dye swap). For the final analysis the gene expression levels were dye effect corrected and values for biological replicates were averaged to obtain a matrix with gene expression levels for 4 independent biological (1. Vhlh-/-, 2. Vhlh-/-/Hif1Î±-/-, 3. Vhlh-/-/Hif2Î±-/- and 4. Vhlh-/-/Hif1Î±-/-/Hif2Î±-/-) conditions.

Towards a CRISPR-Based Mouse Model of Vhl-deficient Clear Cell Kidney Cancer: Initial Experience and Lessons Learned

Project description:CRISPR is revolutionizing the ability to do somatic gene editing in mice for the purpose of creating new cancer models. Inactivation of the VHL tumor suppressor gene is the signature initiating event in the most common form of kidney cancer, clear cell renal cell carcinoma (ccRCC). Such tumors are usually driven by the excessive HIF2 activity that arises when the VHL gene product, pVHL, is defective. Given the pressing need for a robust immunocompetent mouse model of human ccRCC, we directly injected adenovirus-associated viruses (AAVs) encoding sgRNAs against VHL and other known/suspected ccRCC tumor suppressor genes into the kidneys of C57BL/6 mice under conditions where Cas9 was under the control of one of two different kidney-specific promoters (Cdh16 or Pax8) to induce kidney tumors. An AAV targeting Vhl, Pbrm1, Keap1 and Tsc1 reproducibly caused macroscopic ccRCCs that partially resembled human ccRCC tumors with respect to transcriptome and cell of origin and responded to a ccRCC standard of care agent, axitinib. RNAseq analysis was utilized to evaluate the expression profile produced by the targeted loss of Vhl, Pbrm1, Keap1 and Tsc1 in these mouse tumors. Unfortunately, these tumors, like those produced by earlier genetically engineered mouse ccRCCs, are HIF2-independent.

Translational profiling of proximal tubule in fibrotic kidney

Project description:Injury to the proximal tubule plays a central role in the initiation and progression of kidney fibrosis, and rates of chronic kidney disease progresses approximately 50% faster in males compared to females. We applied Translating Ribosome Affinity Purification (TRAP) followed by RNA-sequencing to characterize the cell-specific proximal tubule transcriptional landscape during fibrosis in male vs. female mice.
