Proteomes of ZIP8-wildtype and ZIP8-KO HeLa cell lines

ABSTRACT: The human ZRT/IRT-like protein 8 (ZIP8), encoded by the solute carrier family 39 member 8 gene SLC39A8, is a metal cation symporter located mainly on the cell membrane. ZIP8 is well-known for its role in transporting divalent metal ions into the cells – these ions include several essential micronutrients (e.g., iron [Fe], manganese [Mn], and zinc [Zn]) and non-essential toxic heavy metal cadmium (Cd). In the current project, ZIP8 gene in the human cervical cancer HeLa cell line was knockout (KO) using the CRISPR/Cas9 genome editing technology. Then, the proteomes of ZIP8-KO HeLa cell line and HeLa parental cell line (with wildtype ZIP8 gene sequence) were quantified using iTRAQ and LC-MS/MS.

RNAseq of human epithelial lung carcinoma cell line A549 exposed to ceria, silver or zinc ions, micron-sized particles or nanoparticles

Project description:The toxicity of silver and zinc oxide nanoparticles is hypothesised to be mediated by dissolved metal ions and cerium dioxide nanoparticles (CeO2 NPs) are hypothesised to induce toxicity specifically by oxidative stress dependant on their surface redox state. To test these hypotheses, RNAseq was applied to characterise the molecular responses of cells to metal nanoparticle and metal ion exposures. The human epithelial lung carcinoma cell line A549 was exposed to different CeO2 NPs with different surface charges, micron-sized and nano-sized silver particles and silver ions, micron-sized and nano-sized zinc oxide particles and zinc ions, or control conditions, for 1 hour, 6 hours and 24 hours. Concentrations were the lower of either EC20 or 128 micrograms/mL. Transcriptional responses were characterised by RNAseq transcriptomics using an Illumina HiSeq2500 .

Expression data in BEAS-2B cells and HCT116 cells incubated with copper(II) for different times

Project description:Copper induced stress is known to involve an enhanced oxidant production. This event could be accompanied by an antioxidant response. However, additional processes transcriptionally regulated might participate in the protective response against the metal ions. We used microarrays to detail the global programme of gene expression due to the copper overload and outline the cell processes mostly involved in the toxicity of the metal ions in two cell lines, BEAS-2B cells and HCT116 cells.

Enterococcus faecalis EfaR mutant transcriptome profile

Project description:Metal ions are important cofactors of inumerous enzymes and can interfere in many biological processes. Manganese is a particularly relevant metal as it is also involved in protection from oxidative stress and several Mn-dependent regulators have been shown to have a role in bacterial pathogenicity. A putative DNA-binding motif, here called efa motif was discovered in the promoter regions of genes previously shown to be differentially expressed in the presence of excess zinc, manganese and copper ions. This motif led to the finding and study of the genes putatively involved in the maintenance of manganese homeostasis in E. faecalis. In these genes is included the efaCBA operon, regulated by the Mn-dependent regulator EfaR. Other genes with this efa motif are shown to be regulated by EfaR. Regulation of these efa motif genes by EfaR is discussed as well as some clues on metal interaction with EfaR. Experiments mimicking conditions occurring on biological processes in the host showed that an EfaR plays an important role in biological processes crucial for E. faecalis colonization and virulence.

The effect of CuO nanoparticles on gene expression patterns in Daphnia magna

Project description:There is still a lot of contradiction on whether metal ions are solely responsible for the observed the toxicity of ZnO and CuO nanoparticles to aquatic species. While most tests have studied nanoparticle effects at organismal levels (e.g. mortality, reproduction), effects at suborganismal levels may clarify the role of metal ions, nanoparticles and nanoparticle aggregates. In this study, the effect of ZnO, CuO nanoparticles and zinc, copper salts was tested on the gene expression levels in Daphnia magna. D. magna was exposed during 96 hours to 10% immobilization concentrations of all chemicals, after which daphnids were sampled for a differential gene expression analysis using microarray. When comparing the nanoparticle exposed daphnids (ZnO or CuO) to the metal salt exposed daphnids (zinc or copper salt), the microarray results showed no significantly differentially expressed genes. These results indicate that the toxicity of the tested ZnO and CuO nanoparticles to D. magna caused is solely caused by toxic metal ions. 4 replicate exposures of ZnO nanoparticles, ZnCl2, Blank (for Zn); 4 replicate exposures of CuO nanoparticles, CuCl2.2H2O, Blank (for Cu); Individual reference design with swapped dyes for zinc (e.g. ZnO-REFZn; REFZn-bl) and copper exposure (e.g. CuO-REFCu; REFCu-bl); Zinc reference sample is a mixture of equal aliquots of ZnO nanoparticle, ZnCl2 and blank; Copper reference sample is a mixture of equal aliquots of CuO nanoparticle, CuCl2.2H2O and blank

Salmonella response to copper and zinc

Project description:Salmonella can infect a wide range of hosts and survive in the environment. This invasive pathogen has therefore evolved and acquired specific traits to cope with different, and in most cases unfavorable, conditions. In particular, transition metal ions are widely spread in these niches. These ions are essential in biology and play key roles in the structure-function of a large number of proteins. They can also be toxic, especially at high concentrations. Intracellular metal ion concentrations must therefore be tightly controlled to maintain normal metabolism. Salmonella has acquired traits to deal with the presence of toxic concentrations of some of these ions and, at the same time, to fulfill its requirement for essential metal ions when they are scarce. In this work we analyze the transcriptional response of Salmonella enterica to copper and zinc, two of these essential metals, in both rich (SLB) and defined (M9) media and at short times (10 minutes). This tiling-array based work provides a detailed description of the main transcriptional response when Salmonella detects fluctuations in copper and zinc concentrations.
