Analysis of Bacillus subtilis intracellular proteome under exposition to silver nanoparticles

ABSTRACT: Nanoparticles are more and more used in industrial process, food, medicinal or daily goods. At the end of their life, most of them are discharged in the environment where they impact the ecological equilibrium. Bacteria are one of the first targets of the nanoparticles in the environment. To evaluate the impact of silver nanoparticles on the physiology of Bacillus subtilis, we studied the intracellular proteome of bacteria exposed to different nanoparticles during the stationary phase.

For many years, silver nanoparticles, as with other antibacterial nanoparticles, have been extensively used in manufactured products. However, their fate in the environment is unclear and raises questions. We studied the fate of silver nanoparticles in the presence of bacteria under growth conditions that are similar to those found naturally in the environment (that is, bacteria in a stationary phase with low nutrient concentrations). We demonstrated that the viability and the metabolism of a gr ...[more]

Proteomic analysis of psychrophilic and mesophilic bacterial species

Project description:This study, in an attempt to mimic the molecular adaptation of polar microorganisms, combines proteomic approaches with a classical microbiological analysis in several bacterial species. The comparison of the strategies employed by each bacterial species estimates the contribution of genome versus environmental variables in the adaptation to temperature. Regarding the molecular machinery used by these bacteria to face the consequences of temperature changes, chaperones have a pivoting role. They form complexes with other proteins in the response to the environment, establishing cooperation with transmembrane proteins, elongation factors, and proteins for protection against oxidative damage.

Mechanisms of response to silver nanoparticles Enchytraeus albidus (Oligochaeta): survival, reproduction and gene expression profile

Project description:Due to its antimicrobial activity, silver nanoparticles (Ag-NPs) are among the most used NPs worldwide, yet little information is available regarding their effects, particularly in soil dwelling organisms. Enchytraeids (Oligochaeta) are important members of the soil fauna which actively contribute to the acceleration of organic matter decomposition and nutrient recycling processes. Hence, for hazard and risk assessment it is important to provide toxicity data for these organisms and to understand more in regard to the mode of action of Ag-NPs within organism. To study this we conducted toxicity experiments using the OECD standard guideline, testing Ag-NPs and AgNO3, having assessed survival, reproduction and differential gene expression. Population toxicity responses were assessed showing higher toxicity for the AgNO3. In an attempt to understand the mode of action we performed transcription profiling using the microarray. Gene expression profile of Enchytraeus albidus was analysed after 2 days of exposure to 100 and 200 mg/kg of two silver forms (nanoparticles and salt_silver nitrate) in OECD soil. Three biological replicates per test treatment and control (clean OECD soil) were used.

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 .

Silica nanoparticles effects on gene expression of A549 cells

Project description:Expansion of nanotechnology will bring many potential benefits as adversely effects on human health. Protection of the human respiratory system from exposure of volatile nanoparticles has become an emerging health concern. The understanding of the biological processes involved in the development and maintenance of a variety of pathologies is improved by genome-wide approaches. Technical feasibility of this type of experiment has perfected in recent years, but data analysis remains challenging. In this context, gene set analysis has emerged as a fundamental tool for the interpretation of the results. We demonstrate how the use of a combination of gene-by-gene and gene set analyses can enhance the interpretation of results. Gene set analyses are able to distinguish responses due to nanoparticle size also discriminating between long and short time recovery after exposure. Transcription regulation and cell proliferation modulation appear to be an early response while oxidative stress and mitochondrial perturbation are late response. Moreover, smaller the particle higher the effect on inflammatory response and DNA damage activation. By integrating the two approaches, we evidenced the importance of MMP1, MMP9, MMP7 and MMP14 genes in response to LudoxÂ® silica nanoparticles and the involvement apoptosis process in cell viability. This study is based on the treatment of A549 cells with two different silica nanoparticles (SM30, 9 nm of diameter, and AS30, 18 nm of diameter). Treatment with nanoparticles were performed independently. We performed three biological replicates for each condition.

Dual Function of Tropodithietic Acid as Antibiotic and Signaling Molecule in Quorum Sensing

Project description:The marine bacterium Phaeobacter inhibens produces tropodithietic acid (TDA), a broad-spectrum antibiotic and anticancer agent. TDA allows P. inhibens to antagonize other bacteria, including several pathogens, and eukaryotes. Since recently antibiotics are also discussed to function as intermicrobial signals. Here we show that ~10% of the genes of P. inhibens are strongly influenced by N-acyl-homoserine lactone (AHL) mediated quorum sensing (QS), switching the bacteriumâs life style from attached to free-living. In an AHL negative mutant of P. inhibens subinhibitory concentrations of TDA caused the same regulatory effect as the AHL. This demonstrates that bacteria can produce antibiotic compounds not only as weapons, but also to substitute their endogenous AHL molecule in QS. The dual function of TDA probably supports the QS system to accelerate regulatory processes and points to a so far neglected role of antibiotics at subinhibitory concentrations in the environment and in microbial interactions. Comparison of whole transcriptomes of wildytype, quorum sensing mutants (pgaI and pgaR) and pgaI grown supplemented with subinhibitory concentration of the antibiotic TDA. RNA isolated in the late exponential growth phase. 4 biological replicates investigated for each strain.

Interaction of TiO2 nanoparticles with lung fluid proteins and the resulting macrophage inflammatory response

Project description:Inhalation is a major nanoparticle exposure pathway. Following inhalation, nanoparticles first interact with the lung lining fluid, a complex mixture of proteins, lipids, and mucins. We measure the concentration and composition of lung fluid proteins adsorbed on the surface of titanium dioxide (TiO2) nanoparticles. Using proteomics, we find that lung fluid results in a unique protein corona on the surface of the TiO2 nanoparticles.
