Project description:The miRNA expression profiles of of EBV-infected YT and NK92 cells are compared. YT cells have weaker expression of T-bet and IFNg than NK92 cells. It was found that the EBV-encoded miR-BART20-5p inhibits the expression of T-bet and IFNg in YT cells.
Project description:YT and NK92 cells are EBV-infected lymphoma cells of NK- cell origin. YT cells have weaker expression of T-bet and IFNg than NK92 cells. However, this data set shows that both cell lines have similar mRNA levels, implying post-transcriptional regulations.
Project description:The survival, pollutant degradation activity and transcriptome response was monitored in Sphingomonas sp. LH128 inoculated into soil. Cultivable cell numbers were determined by plating, while phenanthrene degradation was monitored by HPLC. The genetic base for the adaptive strategy of LH128 in soil was investigated by using microarray consisting 7,200 gene-coding ORFs. During 4 hours of incubation, 510 genes were differentially expressed (317 increased and 193 reduced expression) while 610 genes were differentially expressed (318 increased and 292 reduced) after 10 days of incubation. Genes with increased expression comprised of gene encoding PAH catabolic enzymes, stress resistance, oxidative stress tolerance, outer membrane proteins/porins and efflux pump proteins while the downregulated genes comprised of genes encoding flagellar biosynthesis, ribosomal proteins and ATPase. Transcriptomic response of phenanthrene degrading Sphingomonas sp. LH128 inoculated into phenanthrene contaminated soil after 4h and after 10 days of incubation was studied using genome-wide gene expression analysis. For this purpose, the strain was pregrown in minimal medium and inoculated at appropriated celld densitites. RNA was extracted both from soil and and from initial inoculum and cDNA was synthesized and labeled with Cy3. Transcriptomic response in soil of three replicates per conditions after both incubation duration were analyzed and compared with the initial inoculum

It was found that the EBV-encoded miR-BART20-5p inhibits the expression of T-bet and IFNg in YT cells. Approximately 100 ng total RNAs from YT and NK92 cells were used as the input. The GeneChip miRNA 2.0 array from Affymetrix, including probes for 44 EBV-encoded miRNAs and 1105 human miRNAs, was used. The experiments were performed in the microarray core laboratory of National Health Research Institute, Taiwan.
Project description:In general, the endosphere isolate EC18 showed more numbers of genes significantly altered in the presence of root exudates than the soil isolate SB8 . Some of the altered genes in the two strains showed overlap. Some of these genes were previously reported to be involved in microbe-plant interactions, such as organic substance metabolism, oxidation reduction, transmembrane transportation and a subset with putative or unknown function. It was also found some genes showed opposite trend among the two strains.
