This laboratory has shown that a human urothelial cell line (UROtsa) transformed by cadmium (Cd(2+)) produced subcutaneous tumor heterotransplants that resemble human transitional cell carcinoma (TCC). In the present study, additional Cd(2+) transformed cell lines were isolated to determine if independent exposures of the cell line to Cd(2+) would result in malignantly transformed cell lines possessing similar phenotypic properties. Seven independent isolates were isolated and assessed for their ...[more]

Project description:Aberrant DNA methylation is frequently observed in cancer. The aim of this study was to determine how DNA methylation is changed after toxicant-induced malignant transformation. This study also puts the DNA methylation changes into context with respect to the aberrant DNA methylation events that occur in bladder and prostate carcinogenesis not associated with toxicant exposure. Immortalized UROtsa (n=3) and RWPE-1 (n=2) are compared to normal HUC (n=2) and PrEC (n=2), respectively. Arsenite (n=1), monomethylarsonous acid (n=2) or cadmium (n=1) transformed UROtsa are compared to parental UROtsa (n=3). Arsenite (n=2), cadmium (n=1) or MNU (n=1) transformed RWPE-1 cells are compared to parental RWPE-1 cells (n=2). Clinical bladder tumor biopsies (n=6), urothelial carcinoma cell lines (n=2) and prostate cancer cell lines (n=3) are compared to thier normal tissue counterparts HUC (n=2) and PrEC (n=2). Immunoprecipitation using anti-methylcytosine (5MeC) antibody.

Project description:Purpose: Cadmium is a nonessential heavy metal and a well known toxic agent. Cadmium is known to alter the gene expression and signaling but the role of miRNAs during Cadmium exposure is not understood. Methods: Mice were treated with 100 mg/ ml cadmium chloride for 120 days and accumulation of cadmium in blood and organs are confirmed by GFAAS. Subsequently, the total RNA was isolated from the whole blood and small RNA sequencing was executed in Illumina HiSeq 1000. Results: The reads were annotated to the mice genome and miRNAs in miRbase using miRDeep* and novel miRNAs were also predicted. The differential expression was studied by DeSeq Conclusions: This is the first report to reveal the cadmium responsive miRNome. These candidate miRNAs can serve as biomarkers for cadmium Whole blood small RNA profiles of control and cadmium exposed mice generated by deep sequencing using Illumina HiSeq 1000

Project description:Metals at high concentrations can exert toxic effects on microorganisms. It has been widely reported that lowering environmental pH reduces effects of cadmium toxicity in bacteria. Understanding the effects of pH-mediated cadmium toxicity on bacteria would be useful for minimizing cadmium toxicity in the environment and gaining insight into the interactions between organic and inorganic components of life. Growth curve analysis confirmed that cadmium was less toxic to Escherichia coli at pH 5 than at pH 7 in M9 minimal salts medium. To better understand the cellular mechanisms by which lowering pH decreases cadmium toxicity, we used DNA microarrays to characterize global gene expression patterns in E. coli in response to cadmium exposure at moderately acidic (5) and neutral (7) values of pH. Higher expression of several stress response genes including hdeA, otsA, and yjbJ at pH 5 after only 5 minutes was observed and may suggest that acidic pH more rapidly induces genes that confer cadmium resistance. Genes involved in transport were more highly expressed at pH 7 than at pH 5 in the presence of cadmium. Of the genes that showed an interaction between pH and cadmium effects, 46% encoded hypothetical proteins, which may have novel functions involved in mitigating cadmium toxicity. GROWTH CONDITIONS FOR MICROARRAY EXPERIMENTS: Two overnight cultures of E. coli K-12 were started in M9 medium. A 250 mL Erlenmeyer flask containing 100 mL of M9 medium was inoculated with 0.5 mL for each of the two overnight cultures, each of which was considered a biological replicate. The cultures were grown on a rotary shaker (200 rpm) at 37 °C until the contents of the flask reached an OD600 of 0.3 (mid-log phase of growth). Each culture was divided into four 25 mL aliquots, transferred to 50 mL conical tubes (Corning), and centrifuged at 2540 x g for 12 minutes. The supernatant was decanted, and the cells were resuspended in 25 mL of M9 medium at pH 7 or pH 5 in the presence or absence (two cultures of each) of 5.4 µM (1 µg/mL) total cadmium, added as CdCl2. The cultures were incubated at 25 °C for either 5 or 15 minutes with manual rotation of the flasks once per minute. After the appropriate amount of time, 15 mL of RNAProtect Bacteria Reagent (Qiagen) was added to each culture to immediately halt all metabolic processes. The solutions were vortexed, incubated at 25 °C for 5 minutes, and centrifuged for 12 minutes at 3750 x g. RNA was extracted from the cell pellets immediately following centrifugation. RNA EXTRACTION AND HYBRIDIZATION PROCEDURES: RNA was extracted and purified using a Masterpure RNA purification kit (Epicentre Technologies). The quantity and quality of the RNA samples were determined spectrophotometrically. Preparation of the cDNA, labeling with Cy3 and Cy5, and successive hybridizations were accomplished using a 3DNA Array 900MPX kit following the manufacturer’s protocols (Genisphere) with the following modifications. 3DNA reverse transcriptase enzyme (Genisphere # RT300320) rather than SuperScript II was added to 1 µg of RNA and 2 µL of a random primer (1 µg/µL). The final cDNA hybridization mix contained 29 µL 2X enhanced cDNA hybridization buffer rather than 2X SDS-based hybridization buffer or 2X formamide-based hybridization buffer. The cDNA mix was hybridized to a cDNA microarray printed by the Microarray and Proteomics Facility at the University of Alberta (Operon version 1.0 oligonucleotides). The arrays were scanned with a Versarray ChipReader (BioRad) with laser power at 75%, photomultiplier tube (PMT) sensitivity at 800 V, and detector gain at 1. DATA ANALYSIS: Each array directly compared transcription at pH 5 and pH 7 for a given cadmium treatment (0 or 5.4 µM cadmium) and exposure time. Dye swaps were performed for each biological replicate for each of the following treatments (8 total arrays): 5 minutes with cadmium exposure, 5 minutes without cadmium exposure, 15 minutes with cadmium exposure, and 15 minutes without cadmium exposure. The 0-minute exposure to cadmium treatment was obtained from the 5-minute microarray without cadmium exposure. Spot intensities and locations were determined using TIGR Spotfinder, Version 3.1.1. All subsequent analyses were performed using the ma-anova package in the open-source statistical software package, R (www.r-project.org), Version 2.4.1. The data were normalized using the regional lowess method. Following normalization the median expression values of genes represented in triplicate on each array were determined for each gene. A mixed model two-way ANOVA for the main fixed effects of pH, cadmium, and their interaction (array and spot were the random effects) were performed (using Type III F-tests) separately for each time point to identify genes for which pH and cadmium interacted to significantly affect expression (FDR-adjusted p ? 0.05).

Project description:Pseudomonas aeruginosa san ai resists a high concentration of up to 7.2 mM of cadmium. Leaving biomass of P. aeruginosa san ai exposed to sub-lethal concentration of cadmium (0.9 mM) adsorbed 75% of added cadmium after 48 hours, while remaining 25% in culture supernatant was adsorbed by exopollysaccaryde, implying a large biosorption potential of leaving biomass and its exopollysaccaryde. Inner cell response on the protein level was investigated by shotgun proteomics approach based on liquid chromatography and tandem mass spectrometry coupled with bioinformatics to identify proteins in complex protein fractions obtained by size exclusion chromatography used to preserve native forms of metalloproteins and protein complexes. Using this approach a total of 59 proteins were observed as up-regulated in cadmium- amended culture. Almost a third of the total number of up-regulated were metalloproteins. P. aeruginosa san ai developed a complex mechanism to adapt to cadmium, based on: extracellular biosorption, bioaccumulation, the formation of biofilm, controlled siderophore production, enhanced respiration and modified protein profile. An increased abundance of proteins involved in cell energy metabolism, amino acid metabolism, cell motility and posttranslational modifications, primarily based on thiol-disulfide exchange, were observed. Enhanced oxygen consumption of biomass in cadmium- amended culture versus control was found. Our results signify that P. aeruginosa san ai has a great potential for application in bioremediation of cadmium polluted sites.

Project description:Cadmium (Cd) is a toxic metal causing sublethal and chronic effects in crustaceans. Omic technologies offer unprecedented opportunities to better understand modes of toxicity by providing a holistic view of the molecular changes underlying physiological disruption. We sought to use gene expression and metabolomic analyses to reveal the processes leading to chronic Cd toxicity in the indicator species, Daphnia magna, after a 24-h sublethal exposure (18 ug/L, corresponding to 1/10 LC50). We first confirmed that metabolites can be detected and identified in small volumes (~3-6 ul) of D. magna hemolymph using Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry and NMR spectroscopy. We then compared the altered metabolite levels from a mass spectrometry metabolomics study to differentially expressed genes identified by a D. magna 44k oligonucleotide microarray. Metabolomics identified several essential amino acids, nucleotides and fatty acids as decreased in D. magna hemolymph following Cd exposure. Transcriptional changes included decreased levels of digestive enzymes and increased expression of genes related to embryonic development. The integration of metabolomic and transcriptomic profiles, as well as incorporation of results from previous studies, has enabled construction of a conceptual model detailing how sublethal Cd disrupts energy reserves and reproduction resulting in chronic toxicity. Daphnia magna were exposed to 18 micrograms/L Cadmium sulfate for 24 hours. RNA was extracted and hybridized to a custom Daphnia magna microarray to determine genes differentially expressed by the treatment.

Project description:The toxicity of the heavy metal cadmium is well established. However, the molecular basis for how this toxicity perturbs cellular viability is still not well understood. This project investigates the cellular and molecular impacts of cadmium stress in the bacterial pathogen, Streptococcus pneumoniae. We find that cadmium depletes cellular manganese and zinc stores, leading to disruption of metalloproteins and the corresponding biochemical pathways. Furthermore, the over-accumulation of cadmium within the cells appears to facilitate mismetallation events, whereby native metal cofactors are displaced by cadmium, leading to reduced or abrogated enzymatic activity. These metalloproteomic analyses have been conducted in conjunction with transcriptomics and metabolomics to elucidate the global impacts of cadmium stress within a prokaryotic organism.
