Proteomics Reveals the Effect of Environmental Change on Protist Ecophysiology

ABSTRACT: Protist predators are the primary agents of top-down control of bacteria and primary producers, and thus key organisms determining the fate and transport of organic matter in nature. In this study, we address the effects of light and silver stress on the mixotrophic protist Poterioochromonas malhamensis by means of mass spectrometry-based label-free proteomics.

Aquatic environments are heavily impacted by human activities including climate warming and the introduction of xenobiotics. Due to the application of silver nanoparticles as bactericidal agent the introduction of silver into the environment strongly has increased during the past years. Silver ions affect the primary metabolism of algae, in particular photosynthesis. Mixotrophic algae are an interesting test case as they do not exclusively rely on photosynthesis which may attenuate the harmful e ...[more]

RNA-Seq of Brachypodium distachyon callus treated with methyl-jasmonate

Project description:The aim was to determine the changes in cell wall composition and transcriptome changes following treatment with the stress hormone precursor methyl jasmonate (MeJA) in the model grass Brachypodium distachyon. The correlation between transcript changes and cell wall composition changes allowed identification of candidate genes responsible for grass-specific features of the cell wall that are specifically changed in response to MeJA.

Fermentative Spirochaetes drive nutrient cycling by a subsurface microbial loop in hydrocarbon-contaminated habitats

Project description:Members of the bacterial phylum Spirochaetes are primarily studied for their commensal and pathogenic roles in animal hosts. However, Spirochaetes are also frequently detected in anoxic hydrocarbon-contaminated environments but their ecological role in such ecosystems has so far remained unclear. Here we provide a functional trait to these frequently detected organisms with an example of a sulfate-reducing, naphthalene-degrading enrichment culture consisting of a sulfate-reducing deltaproteobacterium Desulfobacterium naphthalenivorans and a novel spirochete Rectinema cohabitans. Using a combination of genomic, proteomic, and physiological studies we show that R. cohabitans grows by fermentation of organic compounds derived from biomass from dead cells (necromass). It recycles the derived electrons in the form of H2 to the sulfate-reducing D. naphthalenivorans, thereby supporting naphthalene degradation and forming a simple microbial loop. We provide metagenomic evidence that equivalent associations between Spirochaetes and hydrocarbon-degrading microorganisms are of general importance in hydrocarbon- and organohalide-contaminated ecosystems. We propose that environmental Spirochaetes form a critical component of a microbial loop central to nutrient cycling in subsurface environments. This emphasizes the importance of necromass and H2-cycling in highly toxic contaminated subsurface habitats such as hydrocarbon-polluted aquifers.

Proteomic analysis of Naegleria gruberi mitochondria

Project description:The formation of mitochondria has enabled eukaryotes to thrive and evolve into multitude of unicellular and multicellular species. The nature of the early mitochondria and its relationship to the ancestral host cell is still unknown. Using a phylogenomic approach we have discovered the presence of core subunits of type II secretion pathway (T2SS) in several unicellular eukaryotes (protists) belonging to jakobids, hetereloboseans and malawimonads. We show that the proteins carry mitochondrial signal sequences and are localized in the protist mitochondria.The mitochondria of Nagleria gruberi were isolated by differential centrifugation and analysed by mass spectrometry. The data analyses revealed about 1000 proteins enriched in the mitochondrial fraction including the components of T2SS.

Mutant p53R273H regulated microRNA profiling in presence and absence of DNA damage in H1299 cells

Project description:In the present study, we used a high-throughput small RNA deep sequencing followed by a systematic computational analysis to identify genome wide mutant p53R273H regulated miRNAs in both DNA damage dependent and independent context. Several miRNA-mRNA regulatory networks have been predicted that might contribute to mutant p53 GOF properties. Differentially regulated miRNA signature profile has been validated in the lung cancer patients harboring wildtype and mutant p53. We identified specific miRNA signatures for lymph node metastasis associated with p53 mutation in lung adenocarcinoma and also predicted the possible contribution of two mutant p53 regulated miRNAs in EMT process. Furthermore, this study identified a hitherto unknown miRNA in human which might act as one of the crucial downstream targets of GOF mutant p53 to confer oncogenic properties. Determination of mutant p53R273H regulated microRNAs H1299 cells.

Time-series of transcriptome analysis of Bacillus subtilis response to 25 mM potassium acetate and 0.85 M-BM-5M CCCP

Project description:The advent of M-bM-^@M-^XomicsM-bM-^@M-^Y techniques bear significant potential for the assessment of the microbiological stability of foods. This requires the integration of molecular data with their implication for cellular physiology. Here we performed a comparative physiological and transcriptional analysis of Bacillus subtilis stressed with three different weak organic acids: the commonly used food preservatives sorbic- and acetic- acid, plus the well-known uncoupler carbonyl cyanide-m-chlorophenyl hydrazone (CCCP). The concentration of each compound needed to cause a similar reduction of the growth rate negatively correlated with their membrane solubility, and positively with the concentration of undissociated acid. Intracellular acidification was demonstrated by expressing a pH-sensitive GFP derivative. The largest drop in intracellular pH was observed in CCCP-stressed cells and was accompanied by the transcriptional induction of the general stress response (GSR) and SigM regulon, responses known to be induced by acidification. The GSR was induced by acetate, but not by sorbate in mildly-stressed cells. Microarray analysis further revealed that all three acids activate transcriptional programs normally seen upon nutrient limitation and cause diverse responses indicative of an adaptation of the cell envelope. Based on the responses observed and the utilized pH measurements, the inhibitory effect of sorbic acid seems to be more focused on the cell membrane than that of acetic acid or CCCP. Time-series of B. subtilis response to 25 mM potassium acetate and 0.85 M-BM-5M CCCP during controlled growth in batch-fermentors in defined minimal medium (pH 6.4). Samples for microarrays were taken from both the treated and control cultures at 0, 10, 20, 30, 40, and 50 min after addition of acetate and CCCP. Two biologically independent experiments were performed.

miR-522 Pulldown-seq in MDA-MB-468

Project description:Identifying miRNA-regulated genes is key to understanding miRNA function. However, many miRNA recognition elements (MREs) do not follow canonical seed base-pairing rules, making identification of bona fide targets challenging. Here, we apply an unbiased sequencing-based systems approach to characterize miR-522, a member of the oncogenic primate-specific chromosome 19 miRNA cluster, highly expressed in poorly differentiated cancers. To identify miRNA targets, we sequenced full-length transcripts captured by a biotinylated miRNA mimic (this dataset). Within these targets, mostly non-canonical MREs were identified by sequencing RNase-resistant fragments.
