Project description:We have developed an oligoGEArray with 434 genes from Ae. aegypti salivary gland. OligoGEArray was customized with the salivary gland genes chosen from the transcriptome source published by Ribeiro et al (2007). Oligonucleotides (60bp) were designed and array were manufactured by SABiosciences. Using this OligoGEArray, we analyzed the differential expression of salivary trancritptome upon blood feeding. Salivary glands were dissected from 1, 3, 24 and 48 hours post fed (hpf) and unfed Ae. aegypti. Total RNA were extracted and the differential expression of transcriptome were analysed. Quantitative Real-Time PCR was performed on selected genes to validate the OligoGEArray data.

Project description:A differential display experiment was done to compare genes expressed in salivary glands from unfed males, males fed in the presence of females and males fed in the absence of females. Possible differential bands were excised, cloned and sequenced. A macroarray study was done on these clones as probes. RNA from the salivary glands of ticks from the three conditions was labelled and hybridized. Two sets of primers were used in the differential display, and these same two were used in the labelling, so there are two platforms, corresponding to what primer pair was used. Two independent RNA isolations were done, Experiment 1 used one, 2 and 3 the other. Experiment 2 used exposure to X-ray film, while 1 and 3 used a phosphorimager plate. Two exposures of the X-ray film were found to give acceptable results, 1 and 5 min. These were averaged in the analysis. Keywords = salivary_gland Keywords = feeding Keywords = male Keywords = female

Project description:A collection of 1145 clones from an EST project on female tick salivary gland genes was hybridized on glass slides to RNA extracted from several feeding stages of adult female tick salivary glands, including unfed and replete, and from adult male ticks, either unfed or fed in the presence or absence of female ticks. In the female ticks, the early fed (<50 mg) and partially fed (30-200 mg) groups were very similar. The fast feeding (350-500 mg) and replete ticks were similar to each other, but different from the partially fed. The unfed ticks were more similar to the fast feeding – replete groups than the early fed-partially fed groups. In the males, there were differences between the males fed in the presence or absence of females, but overall, these groups were very similar. The unfed ticks were significantly different from the fed ticks. Males showed clear differences with females in expression, as well. The unfed females had high levels of genes involved in protein synthesis, while genes possibly involved in survival on the host, such as anticoagulants, seemed to be most expressed in the early and partially fed states. By contrast, in the males, the protein synthesis genes were expressed more in all three groups, while the putative secreted genes for survival were expressed less. Keywords: time course, effect of feeding, sex, effect of presence of females

The fast feeding (350-500 mg) and replete ticks were similar to each other, but different from the partially fed. The unfed ticks were more similar to the fast feeding â replete groups than the early fed-partially fed groups. In the males, there were differences between the males fed in the presence or absence of females, but overall, these groups were very similar. The unfed ticks were significantly different from the fed ticks. Males showed clear differences with females in expression, as well.

By contrast, in the males, the protein synthesis genes were expressed more in all three groups, while the putative secreted genes for survival were expressed less. Keywords: time course, effect of feeding, sex, effect of presence of females All samples were compared to the partially fed females. Females consisted of five groups: unfed, early fed, partially fed, fast feeding and replete. Four or five biological replicates were done of each, with the dyes used in both possible ways. In the males, three groups were used: unfed, feeding in the presence of females, and feeding in the absence of females. Two biological replicates were done of the feeding males, and one of extracts was hybridized twice for the males fed in the presence of females. Unfed males used one RNA sample, extracted from a large pool of ticks.

Project description:Ticks are notorious carriers of pathogens; these blood-sucking arthropods can spread a variety of deadly diseases. The salivary gland is the main organ in ticks, and this organ begins to develop rapidly when Ixodidae ticks suck blood. When these ticks reach a critical weight, the salivary glands stop developing and begin to degenerate. Specific developmental features of the salivary glands are regulated by multiple factors, such as hormones, proteins and other small molecular substances. In this study, we used iTRAQ quantitative proteomics to study dynamic changes in salivary gland proteins in female Haemaphysalis longicornis at four feeding stages: unfed, partially fed, semi-engorged, and engorged. Through bioinformatics analysis of a large number of proteins, we found that molecular motor- and TCA cycle-related proteins play an important role during the development of the salivary glands. The results of RNAi experiments showed that when dynein, kinesin, isocitrate dehydrogenase, and citrate synthase were knocked down, ticks were unable to suck blood normally. The structure and function of the salivary glands were also significantly affected. In addition, four proteins from H. longicornis were found to have very low homology with those from mammals, including humans. Therefore, it is expected that drugs or antibodies targeting these unique sequences can be designed to kill ticks.

Project description:Background: The Anopheles gambiae salivary glands play a major role in malaria transmission and express a variety of bioactive components that facilitate blood-feeding by preventing platelet aggregation, blood clotting, vasodilatation, and inflammatory and other reactions at the probing site on the vertebrate host. Results: We have performed a global transcriptome analysis of the A. gambiae salivary gland response to blood-feeding, to identify candidate genes that are involved in hematophagy. A total of 4,978 genes were found to be transcribed in this tissue. A comparison of salivary gland transcriptomes prior to and after blood-feeding identified 52 and 41 transcripts that were significantly up-regulated and down-regulated, respectively. Ten genes were further selected to assess their role in the blood-feeding process using RNAi-mediated gene silencing methodology. Depletion of the salivary gland genes encoding D7L2, anophelin, peroxidase, the SG2 precursor, and a 5'nucleotidase gene significantly increased probing time of A. gambiae mosquitoes and thereby their capacity to blood-feed. Conclusions: The salivary gland transcriptome comprises approximately 38% of the total mosquito transcriptome and a small proportion of it is dynamically changing already at two hours in response to blood feeding. A better understanding of the salivary gland transcriptome and its function can contribute to the development of pathogen transmission control strategies and the identification of medically relevant bioactive compounds. Salivary glands from blood-fed vs. unfed A. gambiae. 3 replicates.
