Comparative TMT-based quantitative proteomic analysis of the Tachaea chinensis isopod during parasitism

Project description:Parasitic isopods perforate and attach to the host integument via the mandibles, then feed on hemolymph and exudate from the wounds. Such isopods attack a variety of commercially important fish and crustacean hosts. Like other hematophagous parasites, isopods employ biomolecules that inhibit host blood conglutination and defense. In the present study, a tandem mass tag-based quantitative proteomic approach was used to identify differentially expressed proteins in Tachaea chinensis parasites of shrimp, by comparing parasitic (fed) and pre-parasitic (unfed) individuals. We identified 888 proteins from 1510 total peptides, with a significant difference in 129 between the fed and unfed groups. Among these, 37 were upregulated and 92 were downregulated in unfed T. chinensis. This indicates that T. chinensis may require more energy before parasitism during its search for a host. In addition, as is the case for other blood-sucking parasites, it might secrete antihemostatic, anti-inflammatory and immunomodulatory molecules to facilitate blood meal acquisition. Our study is the first to use a TMT-based proteomic approach to analyze the proteome of isopod parasites, and our results will facilitate our understanding of the molecular mechanisms of isopod parasitism on crustaceans.

Gall aphid saliva LC-MS/MS - Proteins Identified from Saliva and Salivary Glands of the Chinese Gall Aphid Schlechtendalia chinensis

Project description:Aphid saliva plays an essential role in the interaction between aphids and their host plants. Several aphid salivary proteins have been identified and analyzed. However, none of the characterized salivary proteins are from galling aphids. Here we analyzed the salivary proteins from the Chinese gall aphid, Schlechtendalia chinensis using LS-MS/MS analysis. A total of 31 proteins were identified directly from secreted saliva collected via artificial diet, and 141 proteins were identified from protein extracts derived from dissected salivary glands. Among these identified proteins, 17 were found in both secreted saliva and dissected salivary glands. In comparison with salivary proteins identified from three other free living aphids, the most striking feature of the salivary protein from S. chinensis is the existence of high proportion of proteins with binding activity, including DNA binding, protein binding, ATP binding and ion binding proteins et al. We speculate that these binding proteins may be involved in induction of gall formation. Our results provide a framework for future research to elucidate the molecular basis for gall induction by S. chinensis.

Focal adhesion and NRF2 pathway regulate left-right asymmetries of rhesus hippocampus aging: relevance to human hippocampus aging and Alzheimer’s disease

Project description:Left-right asymmetry is a basic character of aging brain; however, the molecular foundation of the left-right asymmetry remains unclear. The morphology, physiology and behavior of rhesus aging are obviously similar to human aging, but the aging-rate of rhesus is roughly three times as fast as human, in which the underlying mechanism needs further investigation. By using of 6-plex tandem mass tag (TMT) labeling, we presented a high throughput quantitative proteomics analysis to 6 group hippocampal samples including left and right hippocampus from 3 years, 6 years and 20 years old rhesus. Our data identified 3391 high-confidence proteins. After screening, we found 340 aging-related proteins of left hippocampus and 334 aging-related proteins of right hippocampus, in which there were 114 overlap proteins. Furthermore, the aging-related proteome of left rhesus hippocampus aging was compared with human aging-related proteome of left hippocampus that was reported by our lab previously. As the results show, we discovered 446 aging-related proteins in rhesus and 830 aging-related proteins in human with an overlap of 106 proteins.

Transcriptomic responses of juvenile Pacific whiteleg shrimp, Litopenaeus vannamei, to hypoxia and hypercapnic hypoxia

Project description:Here we used microarrays to characterize changes in global gene expression in the hepatopancreas of Pacific white shrimp, Litopenaeus vannamei, exposed to short term (4 h) hypoxia (H) or hypercapnic hypoxia (HH) or long term (24 h) H or HH, compared to animals in air-saturated water (normoxia). The transcriptomes of crustaceans exposed to low O2 and high CO2 contained both shared and treatment-specific signature genes (q M-bM-^IM-$ 0.01, FC M-bM-^IM-% 1.5), with shifts characteristic of metabolic depression rather than anaerobic metabolism. Down-regulated signature genes dominated the transcript profile in three of the four treatments (H 4 h, H 24 h, 4 h HH); many of these genes were involved in amino acid or RNA metabolism or in translation, including several tRNA synthetases. Unique patterns of gene expression such as increased lipid metabolism and hemocyanin synthesis (H 24 h) and initiation of apoptosis (24 h HH) were tied to specific treatments. This work contributes insight to the effects that human perturbations might have on estuarine organisms, and the importance of examining the impacts of environmentally relevant combinations of hypoxia and hypercapnia on estuarine populations. L. vannamei were exposed for 4 or 24 hours to one of the following conditions: normoxia, hypoxia or hypercapnic hypoxia. Hepatopancreas tissue from individual animals was dissected, total RNA extracted, labelled and hybridized to oligonucleotide microarrays with probes for 21,864 L. vannamei unigenes. Treatments were repeated until a total of 7 biological replicates was obtained for each time:treatment combination, except for the 24 h normoxia group, represented by 6 replicates.

A Bifunctional SPD-0090 contributes virulence of Streptococcus pneumoniae by affecting iron transport and galactose metabolism

Project description:Streptococcus pneumoniae (S.pneumoniae) is a Gram-positive bacterial pathogen that colonizes on the mucosal surfaces of the host's nasopharynx and upper respiratory tract and results in pneumonia. In order to survive and infect the host, S.pneumoniae must have obtain essential nutrients, such as transition metal ions . Our previous study had shown that the mRNA and protein levels of SPD-0090 are significantly upregulated in the ΔpiuA/ΔpiaA/ΔpitA triple mutant (three major iron transports), but its detailed biological function is unknown. In this study, we found that the knockout spd-0090 gene induced a delayed growth in the medium with different sugar sources. F urther iTRAQ quantitative proteomics studies revealed that SPD-0090 affects galactose metabolism and iron ion transport system. Then RT-qPCR and intracellular galactose content assays showed that SPD-0090 affects galactose uptake, leads to reduced galactose utilization. In addition, in vitro biochemical assays showed that SPD-0090 is a hemin transporter and affects iron uptake. Notably the knockout of spd-0090 resulted in an enhanced infection ability of S.pneumonaie to Our study reveals that the dual function of SPD-0090 plays an important role in the virulence of S.pneumoniae.

Comparison of two clones (4106a and FRC) of Myzus Persicae (Sulzer) (Hemiptera: Aphididae)

Project description:The aim of this experiment was to compare the transciptome of the peach-potato aphid (Myzus persicae) clone 4106a (a laboratory insecticide-susceptible standard collected from potato in Scotland in 2000) with clone FRC (an insecticide resistant aphid clone collected from peach in France in 2009) to identify which genes are over or underexpressed in the resistant phenotype. The custom microarray used in this study was designed using the Agilent eArray platform (Agilent Technologies) by the Georg Jander Lab and is based on a previously described array containing probes for >10, 000 M. persicae unigenes produced by Sanger sequencing (Ramsey, Wilson et al. 2007) augmented with an additional 30, 517 probe set designed on EST unigene sequences identified in a 454 sequencing project (Ramsey, Rider et al. 2010). The final slide layout consists of four arrays of 45, 220 60-mer probes and these are produced by Agilent by in situ oligonucleotide synthesis. References: Ramsey, J. S., D. S. Rider, et al. (2010).
