Project description:The whitefly Bemisia tabaci is a notorious pest of worldwide agriculture. It is believed to secrete saliva to counter plant defenses, but the underlying mechanism remains to be elucidated. Here, we characterize the gene/protein repertoires of B. tabaci salivary glands and secreted saliva by transcriptomic and LC–MS/MS analysis. A total of 698 salivary gland-higher expressed unigenes, as well as 172 saliva proteins are identified. Comparative analysis of the saliva composition in different arthropod species illustrates that proteins associated with binding, hydrolysis and oxidation-reduction are widely distributed in herbivorous saliva. There are 74 saliva proteins exclusively identified in B. tabaci, with 34 of them being B. tabaci-specific. In addition, eleven B. tabaci-specific saliva proteins plastically regulated in response to different diets, which might be associated with wide host range of this pest. Our results gain insight into whitefly–plant interactions, and provide a good resource for functional characterization of effectors

Project description:The two-spotted spider mite Tetranychus urticae is an extreme polyphaguous crop pest. Next to an increased detoxification potential of plant secondary metabolites, it has recently been shown that spider mites manipulate plant defences. Salivary constituents are proposed to play an important role during the interaction with its many hosts. The proteomic composition of saliva delivered into artificial diet by spider mites adapted to various hosts - bean, soy, maize, tomato -was determined using Orbitrap mass spectrometry. Over 200 different proteins were identified, many of unknown function and in numerous cases belonging to multi-membered gene families. A selection of these putative salivary proteins was validated using whole-mount in situ hybridizations and expression was shown to be localized in the anterior and dorsal podocephalic glands of the spider mite. Host-plant dependent expression was evident from the proteomics dataset and was further studied in detail by micro-array based genome wide gene expression profiling of mites maintained on the host plants under study. Previously obtained gene-expression datasets were further used to get more insight in the expression profile over different life stages and physiological states. To conclude, for the first time the T. urticae salivary proteome repertoire was characterized using a custom feeding hemisphere-based enrichment technique. This knowledge will assist in unraveling the molecular interactions between phytophagous mites and their host plants. This may ultimately facilitate the development of mite-resistant crops.

Project description:Tissue microRNAs (miRNAs) can detect cancers and predict prognosis. Several recent studies reported that tissue, plasma, and saliva miRNAs share similar expression profiles. In this study, we investigated the diagnostic value of salivary miRNAs (including whole saliva and saliva supernatant) for detection of esophageal cancer. By Agilent microarray, six deregulated miRNAs from whole saliva samples from seven patients with esophageal cancer and three healthy controls were selected. The six selected miRNAs were subjected to validation of their expression levels by RT-qPCR using both whole saliva and saliva supernatant samples from an independent set of 39 patients with esophageal cancer and 19 healthy controls.

Project description:Purpose: Ribosome profiling and RNA-Seq were used to map the location and abundance of translating ribosomes on human skeletal muscle transcripts from a patient with Becker muscular dystrophy. Methods: Tissue homogenates were prepared from frozen sections of a muscle biopsy obtained from a patient with an NM_004006:c.40_41delGA dystrophin mutation and a normal control. Ribosome-protected fragments and total RNA were prepared from a single homogenate, so starting RNA populations for both libraries were closely matched. Homogenates were not clarified before RNase digestion to avoid loss of ribosomes associated with large molecular weight complexes and RNA-Seq libraries were prepared after rRNA subtraction to avoid positional loss of 5’ reads. RPF-Seq libraries were built using the TruSeq Small RNA Sample Preparation Kit (Illumina) and RNA-Seq libraries were built using the TruSeq RNA Sample Preparation v2 Kit (Illumina). RPF-Seq and RNA-Seq libraries were subjected to 50 cycles of single-end sequencing on an Illumina HiSeq 2000 instrument. Trimmed and filtered RPF- and RNA-Seq reads were mapped to RefSeq fasta sequences downloaded from the UCSC genome browser (hg19 assembly). Results: Most mutations that truncate the reading frame of the DMD gene result in loss of dystrophin expression and lead to Duchenne muscular dystrophy. However, amelioration of disease severity can result from alternate translation initiation beginning in DMD exon 6 that results in the expression of a highly functional N-truncated dystrophin. This novel isoform results from usage of an internal ribosome entry site (IRES) within exon 5 that is glucocorticoid-inducible. IRES activity is confirmed in patient muscle by both peptide sequencing and ribosomal profiling. Conclusions: Our results provide a molecular explanation for the rescue of 5’ truncating mutations via a heretofore undescribed mechanism of post-transcriptional regulation of dystrophin expression. The presence of a glucocorticoid-inducible IRES within a highly conserved region of the DMD sequence strongly suggests a programmed role for alternate translation initiation, and ongoing efforts to understand the relevant cell lineage-specific and/or conditional activation signals will shed light on underlying mechanisms of IRES control and elucidate potentially novel functions of dystrophin. Skeletal muscle ribosome-protected fragment and RNA-Seq profiles from a patient with an NM_004006:c.40_41delGA dystrophin mutation and a normal control were generated by deep sequencing using the Illumina HiSeq 2000.

Project description:Bisphenols are used in the process of polymerization of polycarbonate plastics and epoxy resins, which have numerous applications in a variety of consumer products. Due to their hydrophobic properties, bisphenols can easily migrate out of plastic products especially into fatty foods. They have been found in brain, liver, adipose tissue and body fluids, illustrating their environmental prevalence. By increasing colonic inflammation in mice, disrupting the intestinal bacterial community structure and altering the microbial membrane transport system in zebrafish, bisphenols seem to interfere with the gut microbiome. The highly abundant human commensal bacterium Bacteroides thetaiotaomicron was exposed to bisphenols (Bisphenol A (BPA), Bisphenol F (BPF), Bisphenol S (BPS)), to examine the mode of action, in particular of BPF. All chemicals caused a concentration-dependent growth inhibition and the half-maximal effective concentration (EC50) corresponded to their individual logP values, a measure of their hydrophobicity. B. thetaiotaomicron exposed to BPF decreased membrane fluidity with increasing BPF concentrations. Physiological changes including an increase of acetate concentration were observed in cells treated with 0.57 mM BPF. On the proteome level, a higher abundance of several ATP synthase subunits and multidrug efflux pumps suggested an increased energy demand for adaptive mechanisms after BPF exposure. Defence mechanisms were also implicated by a pathway analysis, that identified a higher abundance of members of resistance pathways/strategies to cope with xenobiotics (i.e. antibiotics). Here, we present further insights into the mode of action of bisphenols in a human commensal gut bacterium regarding growth inhibition, and the physiological and functional state of the cell. These results, combined with microbiota-directed effects, could lead to a better understanding of host health disturbances and disease development based on xenobiotic uptake.

Project description:Ixodes scapularis and other hard ticks are long-term blood feeders. This feeding behavior is facilitated by a tick secreted bio adhesive (tick cement) that attaches tick mouthparts to skin tissue and prevents the host from dislodging the tick from its feeding site. Understanding tick cement formation is highly sought after as its disruption will prevent tick feeding. This study describes proteins that form the inner core layer of I. scapularis tick cement as disrupting these will stop formation of the outer cortical layer. As the inner core cement layer completes forming by 24 h of attachment, we used laser capture to isolate cement from cryosections of 6 h and 24 h tick attachment sites and to distinguish between early and late inner core cement proteins. LC-MS/MS analysis identified 138 tick cement proteins (TCPs) of which 37 and 35 were unique in cement of 6 and 24 h respectively, and 66 shared proteins. The 138 TCPs are classified in 14 functional categories: cuticular protein (16%), tick specific proteins of unknown function, cytoskeletal proteins, and enzymes (at 13% each), enzymes (10%), antioxidant, glycine rich, scaffolding, heat shock, histone, histamine binding, proteases and protease inhibitors, and miscellaneous (at 3-6% each). Gene ontology analysis confirm that TCPs are enriched for bio adhesive properties. Our data offer insights into yet unknown tick cement bonding patterns and set the foundation for understanding the molecular basis of I. scapularis tick cement formation.

Project description:The tight synchronization between the life cycle of the obligatory parasitic mite Varroa destructor (Varroa) and its host the honeybee, is mediated by honeybee chemical stimuli. These stimuli are mainly perceived by a pit organ located at the distal part of the mite’s foreleg. In the present study, we searched for Varroa chemosensory molecular components by comparing transcriptomic and proteomic profiles between forelegs from different physiological stages, and rear legs. In general, a comparative transcriptomic analysis showed a clear separation of the expression profiles between the rear legs and the three groups of forelegs (phoretic, reproductive and tray-collected mites). Most of the differentially expressed transcripts and proteins in the mite’s foreleg were previously uncharacterized. Using a conserved domain approach, we identified 54 transcripts with known chemosensory-related domains, of which 17 were significantly up regulated in the mite’s forelegs when compared to rear legs. We characterized the chemosensory transcripts using phylogenetic analysis.
