Jasmonate controls polypeptide patterning in undamaged tissue in wounded Arabidopsis leaves.

Wounding initiates a strong and largely jasmonate-dependent remodelling of the transcriptome in the leaf blades of Arabidopsis (Arabidopsis thaliana). How much control do jasmonates exert on wound-induced protein repatterning in leaves? Replicated shotgun proteomic analyses of 2.5-mm-wide leaf strips adjacent to wounds revealed 106 differentially regulated proteins. Many of these gene products have not emerged as being wound regulated in transcriptomic studies. From experiments using the jasmoni ...[more]

Transcription profiling of synchronized Sulfolobus acidocaldarius populations as they progress through the cell cycle

Project description:Exponentially growing Sulfolobus acidocaldarius were treated with NaAc to generate replication runout and arrest in G2 phase. The cells were then resuspended in fresh acetate-free media which generates a synchronous population. Samples for investigation of gene expression change were taken during the synchronised populations progress through the cell cycle.

Transcription profiling of heptatocytes from mice given a high-copper diet

Project description:In order to study the physiological consequences of a high-copper diet on hepatic gene expression, 6 mM CuCl2 was added to the drinking water for a period of 1 month. After this period, livers of seven control mice and eight copper-treated mice were isolated and were subjected to microarray analysis and copper measurements. The hepatic gene expression profile of copper-treated mice was compared to non-treated mice using a pooled reference.

RNAi profiling by array of human HEp-2 cells with siRNA-mediated depletion of RNase MRP protein components

Project description:To identify mRNA substrates for the human RNase MRP complex, we examined the effects of siRNA-mediated depletion of RNase MRP (and RNase P) on the transcriptome of HEp-2 cells. The expression of two RNase MRP protein components, hPop1 and Rpp40, was knocked-down and after 48 hours mRNA was isolated from these cells as well as from cells transfected with an siRNA targeting the GFP mRNA (siEGFP), which was used as a control. The expression levels of mRNAs were analyzed on a genome-wide scale using 21K microarrays.
