Project description:Liriomyza trifolii Transcriptome or Gene expression

Project description:We have previously showed a strong genetic determinant governing resistance of the M. truncatula A17 line to C. trifolii is located in a chromosomal region at the top of chromosome 4 (Ameline-torregrosa et al., 2008). This region also contains the RCT1 gene which has been shown to confer resistance to C. trifolii when transferred to a susceptible alfalfa plants (Zhu et al.), In order to evaluate the role of this region in the response to non-adapted Colletorichum species and to compare this response to those induce by C. trifolii, two M. truncatula near-isogenic lines differing only in this chromosomal region were used for transcript profiling experiments. These two lines were issued from a recombinant-inbred collection obtained from a A17-F83005.5 cross (Cazaux et al., in preparation). Plant inoculations were done on two-week-old entire plants by spraying a conidial suspension of C. trifolii or C. lindemuthianum to avoid possible artifacts which can be observed on detached leaves (Liu et al., 2007). RNA was extracted from leaves collected at 1dpi and 3dpi and transcript profiling was performed using Mt16kOLI1Plus chips (Thompson et al., 2005).

Project description:To evaluate the immune responses in tumor-draining lymph nodes induced by microwave ablation (MWA) or microwave ablation combined with 2DG (MWA+2DG), we then performed gene expression profiling analysis using data obtained from RNA-seq of 5 different lymph nodes from two group of mice.

Project description:Reports that low-intensity microwave radiation can induce heat-shock reporter gene expression in the nematode, Caenorhabditis elegans, have recently been reinterpreted as a subtle thermal effect caused by very slight heating. This study used a microwave exposure system (1.0 GHz, 0.5 W power input; SAR 0.9-3 mW kg-1 for 6-well plates) that minimises the temperature differential between sham and exposed conditions to ≤ 0.1°C. Comparable measurement and simulation studies of SAR distribution within this exposure system are presented. We compared 5 Affymetrix gene-arrays of pooled triplicate RNA populations from sham-exposed L4/adult worms against 5 gene-arrays of pooled RNA from microwave-exposed worms (taken from the same source population in each run). Few genes showed consistent expression changes across all 5 comparisons, and all such expression changes appeared modest after applying standard normalisation procedures (≤ 30% up- or down-regulated). The number of statistically significant differences in gene expression (846) was less than the false-positive rate expected by chance (1131). As one example, an apparent up-regulation of the vit-3 vitellogenin gene by microwave exposure was not mirrored by similar changes affecting the other co-regulated members of the same vit gene family. We conclude that the pattern of gene expression in L4/adult C elegans is not substantially perturbed by low-intensity microwave radiation, and that the minor changes observed in this study may well be explicable as false positives. As a check on the sensitivity of the Affymetrix gene-arrays used, we also compared RNA samples from N2 worms subjected to a sub-heat-shock treatment (28ºC) against controls kept at 26 ºC (but using only 2 gene arrays per condition). After similar normalisation, many more genes (3712) showed substantial expression changes (i.e. > 2-fold at p < 0.05), including a group of six heat-shock genes which were strongly but unexpectedly down-regulated (by > 10-fold). However, further replication and confirmation by real-time RT-PCR would be needed to establish how many of these changes might also be false positives.
