Transcriptome analysis of mesothelioma induced by intraperitoneal injections of ferric saccharate in rats

ABSTRACT: Iron plays an important role in oxidative tissue damage and subsequent carcinogenesis. Iron deposition in the peritoneum causes neoplastic changes. Here we used gene expression microarrays to find common genetic alterations in a rat model by repeated intraperitoneal injections of ferric saccharate. Gene expression microarray revealed the expression of uromodulin (Umod) is increased in mesothelioma approximately 250-fold.

Expression analysis of microRNA in malignant peritoneal mesothelioma induced by intraperitoneal injections of iron saccarate in rats

Project description:Iron plays an important role in oxidative tissue damage and subsequent carcinogenesis. Iron deposition in the peritoneum causes neoplastic changes. Here we used microRNA (miR) microarrays in a rat model by repeated intraperitoneal injections of ferric saccharate. miR microarray revealed the miR-199/214 as a distinctive feature of sarcomatoid mesothelioma.

Transcriptome analysis of mesothelioma induced by intraperitoneal injections of asbestos in rats

Project description:Human malignant mesothelioma (MM) is an aggressive tumor strongly associated with asbestos exposure. SM patients generally have poorer prognosis compared to EM patients. To identify potential genes accounting for the differential prognosis between these two subtypes, we compared the microarray gene expression profiles of rat SM and EM tissues induced by intraperitoneal injections of 3 types of asbestos (chrysotile,crocidolite and amosite). Carcinogenesis protocol was performed using specific pathogen-free male and female F1 hybrid rats between Fischer344 and Brown-Norway strains. A total of 28 microarrays (Whole Rat Genome Microarray) were used for screening purpose: The 2 arrays were used for knife-scraped peritoneal mesothelial cells, 2 arrays for cultured peritoneal mesothelial cells and 24 arrays for MM samples.

Transcriptional profiling of renal cells expressing wild type or mutant uromodulin isoforms.

Project description:Uromodulin is the most abundant urinary protein. It is exclusively produced and released in the urine by renal epithelial cells lining the thick ascending limb of Henle’s loop (TAL). Mutations in UMOD, the gene encoding uromodulin, cause autosomal dominant tubulointerstitial kidney disease uromodulin-related (ADTKD-UMOD). While the primary effect of all mutations, retention in the endoplasmic reticulum (ER), is well established, its downstream effects are still unknown. The aim of this study was to gain insight into ADTKD-UMOD pathogenesis through transcriptional profiling of immortalised mouse TAL cells (mTAL) transduced with lentiviral vectors encoding wild type or mutant (C150S) GFP-tagged human uromodulin.

Ferric Citrate Uptake is a Virulence Factor in Uropathogenic Escherichia coli

Project description:More than half of women will experience a urinary tract infection (UTI) with uropathogenic Escherichia coli (UPEC) causing ~80% of uncomplicated cases. Iron acquisition systems are essential for uropathogenesis, and UPEC encode functionally redundant iron acquisition systems, underlining their importance. However, a recent UPEC clinical isolate, HM7 lacks this functional redundancy and instead encodes a sole siderophore, enterobactin. To determine if E. coli HM7 possesses unidentified iron acquisition systems, we performed RNA-sequencing under iron-limiting conditions and demonstrated the ferric citrate uptake system (fecABCDE and fecIR) was highly upregulated. Importantly, there are high levels of citrate within urine, some of which is bound to iron, and the fec system is highly enriched in UPEC isolates compared to commensal or fecal strains. Therefore, we hypothesized that HM7 and other similar strains use the fec system to acquire iron in the host. Deletion of both enterobactin biosynthesis and ferric citrate uptake (ΔentB/ΔfecA) abrogates use of ferric citrate as an iron source and fecA provides an advantage in pooled human urine in absence of enterobactin. However, in a UTI mouse model, fecA is a fitness factor independent of enterobactin production, likely due to the action of host Lipocalin-2 chelating ferrienterobactin. These findings indicate that ferric citrate uptake is used as an iron source when siderophore efficacy is limited, such as in the host during UTI. Defining these novel compensatory mechanisms and understanding the nutritional hierarchy of preferred iron sources within the urinary tract are important in the search for new approaches to combat UTI.

Uromodulin-retention in thick ascending limb affects SCD1 in neighboring S3 proximal tubule in males: transcriptome studies in mouse models of Uromodulin-associated kidney disease

Project description:Uromodulin-associated kidney disease (UAKD) summarizes different clinical features of an autosomal dominant heritable disease syndrome in humans with a proven uromodulin (UMOD) mutation involved. It is often characterized by hyperuricemia, gout, alteration of urine concentrating ability, as well as a variable rate of disease progression inconstantly leading to renal failure and histological alterations of the kidneys. We recently established the two Umod mutant mouse lines UmodC93F and UmodA227T on the C3H inbred genetic background both showing kidney defects analogous to those found in human UAKD patients. The aim of this study was the further analysis of the phenotypic alterations by examining the kidneys as primarily affected organs. Transcriptome and quantitative PCR analyses as well as IHC analyses found significant changes related to the phenotyping changes. 4 male mice of each mutant cohort (Umod C93F & Umod A227T) and the corresponding wildtype controls, each mutant mouse was compared to the mean of the corresponding wildtype including a technical replicate (dye swap)

Transcriptional profiling of a mouse model of Uromodulin Associated Kidney Disease (UAKD)

Project description:Uromodulin (UMOD) is a secreted glycoprotein exclusively expressed by the cells lining the thick ascending limb of the loop of henle and the early distal tubule of the kidney nephron. Mutations in UMOD that interfere with proper folding of the protein are responsible for a progressive form of interstitial fibrotic kidney disease that leads to end stage renal disease, referred to as Uromodulin Associated Kidney Disease (UAKD). To assess key transcriptional changes associated with the progression of UAKD, we generated a knock-in mouse model harboring the mouse equivalent of the human mutation C148W. We profiled both the whole kidney tissue, as well as the specific UMOD+ cell populaitons in mutant and wild type mice. Analysis of differentially expressed genes in whole tissue and UMOD+ cells revealed a strong TNF-signaling signature, as well as TRIB3 upregulation, which is a key mediator of the intrinsic ER-stress mediated cell death pathway.

Gene expression profiles in MexTAg transgenic mouse and wild type mouse asbestos-induced mesothelioma

Project description:Malignant mesothelioma is an aggressive tumour arising from the mesothelial cells lining the pleura, peritoneum or pericardium. The principal carcinogen associated with malignant mesothelioma is asbestos . A transgenic mouse model, denoted MexTAg, which encodes the Simian Virus 40 (SV40) large T antigen (TAg) downstream of the mesothelin promoter was developed. Inactivation of the tumour suppressors p53 and RB following binding to TAg results. In this model mesothelioma develops in the mesothelial cell compartment after the mice have been exposed to asbestos. The MexTAg transgenic mouse model of mesothelioma model enables analysis of the molecular events associated with asbestos induced mesothelioma and is utilised here to investigate the molecular dynamics of tumours induced in these mice, using gene expression patterns as a read out.

Transcriptional profiling of kidneys from ADTKD-UMOD mouse model

Project description:To gain insight into autosomal dominant tubulointerstitial kidney disease (ADTKD)-uromodulin (UMOD) pathophysiology, we carried out transcriptional profiling of kidneys from 1- and 2-month-old TgUmodC147W mice, a transgenic model that recapitulates the main features of the disease, and TgUmodwt mice, a matched transgenic control of Umod overexpression. These time points correspond to presymptomatic stages that precede renal dysfunction in TgUmodC147W mice.
