Project description:Monitoring microbial communities can aid in understanding the state of these habitats. Environmental DNA (eDNA) techniques provide efficient and comprehensive monitoring by capturing broader diversity. Besides structural profiling, eDNA methods allow the study of functional profiles, encompassing the genes within the microbial community. In this study, three methodologies were compared for functional profiling of microbial communities in estuarine and coastal sites in the Bay of Biscay. The methodologies included inference from 16S metabarcoding data using Tax4Fun, GeoChip microarrays, and shotgun metagenomics.

Project description:We sequenced messenger RNA from mixed stages of the two-spotted spider mite (Tetranychus urticae) reared on bean (Phaseolus vulgaris cv California Red Kidney; the laboratory host plant for mites) and two Arabidopsis thaliana accessions which were considered to either be susceptible (Kondara) or resistant (Bla-2) to mite feeding. This pilot experiment was conducted to assess gene expression differences of mites grown on sensitive versus resistant Arabidopsis accessions, as well as differences in mites feeding on different host species. The expression data was used for gene model validation of genes predicted by EuGene in the spider mite genome and to assess gene expression levels. Examination of gene expression of spider mites reared on beans and two Arabidopsis accessions (Kondara and Bla-2).

Project description:In this study, we profiled the transcriptional changes in a polyphagous spider mite, Tetranychus urticae, after adaptation to spatial and tempospatial stress. We show heritable down-regulation of genes encoding for core enzymes involved in the citric acid and gluconeogenesis/glycolyse pathways (glucose 6-phosphatase among others). Additionally, we observe heritable transcriptional changes in amino acid pathways (methionine, tyrosine and phenylalanine) and in laterally acquired genes from bacteria (cobalamin-independent methionine synthase). By similiar study results in other organisms, we argue that these heritable transcriptional changes (partially) underpin the changed life history traits observed in our experimental evolution set-up.

Project description:Twenty-four nucleotide long miRNAs (lmiRNAs) direct DNA methylation at target genes and regulate their transcription. The evolutionary origin of lmiRNAs and the range of lmiRNA-mediated regulation remain obscure. Here, we reannotated lmiRNAs and their targets in rice by applying stringent criteria. We found that the majority of lmiRNAs are derived from MITEs and most sites targeted by MITE-derived lmiRNAs reside within MITEs, suggesting co-evolution of lmiRNAs and their targets through MITE amplification. lmiRNAs undergo dynamically changes under stressed conditions and the genes targeted by lmiRNAs show an enrichment for stress responsive genes, suggesting that lmiRNAs are widely involved in plant response to stresses. We constructed the evolutionary histories of lmiRNAs and their targets. lmiRNAs emerged before or when the AA genome was diverged, while the emergence of lmiRNA targets coincided with or followed the emergence of lmiRNAs. Furthermore, we found that the sequences of a lmiRNA target site underwent variations, coincident with the divergence of rice accessions and the distribution of rice accessions in different geographical locations and climatic conditions. Our findings highlight MITEs as an important origin of lmiRNAs and suggest that the evolution of lmiRNA-target regulatory modules may contribute to rice adaptation to environmental changes.

Project description:The purpose of this study was to identify genes in keratinocytes and fibroblasts in human skin equivalents that changed expression in response to the burrowing of live scabies mites. Four biological replicates for the uninfested control condition and five biological replicates for the treatment conditions (live mites, mite extract) were processed for gene expression analysis using Affymetrix Human Gene 1.0 ST arrays.

Project description:The PI3K-AKT pathway is known to regulate cytokines in dust mite-induced pediatric asthma. However, the underlying molecular steps involved are not clear. In order to clarify further the molecular steps, this study investigated the expression of certain genes and the involvement of miRNAs in the PI3K-AKT pathway, which might affect the resultant cytokine-secretion. In-vivo and in-vitro ELISA, qRT-PCR, western-blot and microarrays analyses were used in this study. A down-expression of miRNA-27b-3p in dust mite induced asthma group (group D) was found by microarray analysis. This was confirmed by qRT-PCR that found the miRNA-27b-3p transcripts that regulated the expression of SYK and EGFR were also significantly decreased (p < 0.01) in group D. The transcript levels of the SYK and PI3K genes were higher, while those of EGFR were lower in the former group. Meanwhile, we found significant differences in plasma concentrations of some cytokines between the dust mite-induced asthma subjects and the healthy controls. On the other hand, this correlated with the finding that the transcripts of SYK and its downstream PI3K were decreased in HBE transfected with miRNA-27b-3p, but were increased in HBE transfected with the inhibitor in vitro. Our results indicate that the differential expression of the miRNAs in dust mite-induced pediatric asthma may regulate their target gene SYK and may have an impact on the PI3K-AKT pathway associated with the production of cytokines. These findings should add new insight into the pathogenesis of pediatric asthma.
