Early dynamics of photosynthetic Lhcf2 and Lhcf15 transcription and mRNA stabilities in response to herbivory-related decadienal in Phaeodactylum tricornutum

ABSTRACT: During grazing, damaged cells of various diatom species release oxylipins whose functions include signaling to nearby undamaged cells. Our study focused on the effects of the oxylipin 2-trans, 4-trans-decadienal (DD) during the light cycle on photosynthetic light harvesting complex (LHC) mRNA regulation in Phaeodactylum tricornutum. RNAseq data revealed extensive suppression of LHC mRNAs measured at 3 h while a smaller set of LHC mRNAs were up-regulated. RNA metabolic labeling studies of divergently regulated Lhcf2 and Lhcf15 mRNAs documented dynamic shifts in their transcription and mRNA stabilities during the light cycle after DD treatment. The RNAseq dataset offers an extensive resource for expression profiling in the early response period to DD treatment.

Identification of TGA-regulated genes in response to phytoprostane A1 and OPDA

Project description:12-oxo-phytodienoic acid (OPDA) and phytoprostane A1 (PPA1) are cyclopentenone oxylipins that are formed via the enzymatic jasmonate pathway and a nonenzymatic, free radical–catalyzed pathway, respectively. Both types of cyclopentenone oxylipins induce the expression of genes related to detoxification, stress responses, and secondary metabolism, a profile clearly distinct from that of the cyclopentanone jasmonic acid. To investigate the role of TGA transcriction factors in oxylipin responses, the regulation of gene expression by OPDA and PPA1 defective in the expression of TGA2, TGA5, and TGA6 was analyzed using Affymetrix ATH1 chips. Keywords: Arabidopsis tga2-5-6 mutant, Oxylipin treatment, ATH1 Chip

Addressing reproducibility challenges in cell culture: the impact of oxylipins contained in fetal calf serum

Project description:Reproducibility issues regarding complex in vitro cell culture experiments have been mainly attributed to genetic variations within cell lines. Batch-dependent fetal calf serum variations are well known and also represent relevant influencing factors. However, the molecular constituents mediating such effects remained largely unknown. High resolution mass spectrometry is a powerful tool to identify molecular FCS constituents and investigate their effect on cultured cells. Using a differentiation and inflammatory stimulation protocol on U937 cells we observed FCS batch-dependent variations of secreted cytokines, oxylipins and other inflammatory mediators. In order to detect candidate bioactive molecules contained in FCS, the protein and oxylipin composition of FCS batches was investigated. Remarkably, the protein composition showed some, but much less batch-dependent variation when compared to the oxylipin composition. Efficient uptake of C13-labelled arachidonic acid from medium by U937 macrophages and inflammation-induced release thereof including oxylipin products was evidenced. Balancing out FCS batch-dependent nanomolar concentration differences of two selected oxylipins, 5-HETE and 15-HETE, by spiking experiments, resulted in significant proteome alterations of cultured U937 macrophages indicating PPAR activation. High-resolution microscopy demonstrated HETE-induced formation of peroxisomes, thus independently corroborating the proteome profiling results. In conclusion, the present data demonstrate a strong and previously underappreciated influence of FCS-contained oxylipins on cellular effector functions, thus representing a plausible cause for disturbing reproducibility issues.

Determination of Pseudomonas aeruginosa transcriptome induced by oleic acid or its derived oxylipins 10-HOME and 7,10-DiHOME.

Project description:Oxygenated unsaturated fatty acids, known as oxylipins, are signaling molecules commonly used for cell-to-cell communication in eukaryotes. However, a role for oxylipins in mediating communication in prokaryotes has not previously been described. Bacteria mainly communicate via quorum sensing (QS) , which involves the production and detection of diverse small molecules termed autoinducers. We showed that oleic acid-derived oxylipins 10-HOME and 7,10-DiHOME produced by Pseudomonas aeruginosa function as autoinducers of a novel quorum sensing system termed Oxylipin-Dependent QS Sytem (ODS). This experiment was designed to determine the genes whose expression is altered by these P. aeruginosa oxylipins. We found that the ODS system controls the cell density-dependent expression of a P. aeruginosa gene subset through the mediation of 10-HOME and 7,10-DiHOME oxylipins.

Transcriptome and oxylipin profiling joint analysis reveals the opposite roles of 9-oxylipins and jasmonic acid in maize resistance to Gibberella stalk rot

Project description:Gibberella stalk rot (GSR) caused by Fusarium graminearum is one of the devastating diseases causing significant losses to maize production worldwide. Although plant oxylipins have been widely reported as potent signals to activate diverse biotic stress responses, the roles of distinct oxylipin pathway branches initiated by either 9- or 13-lipoxygenases (LOXs) in defense against GSR remain unexplored. In this study, the functional analysis showed that disruption of ZmLOX5, a maize 9-LOX gene, resulted in increased susceptibility to GSR. To identify the key genes and metabolites associated with GSR resistance, we profiled transcriptome and oxylipins in the lox5 mutant and near-isogenic wild type. The results showed that JA biosynthetic pathway genes are highly up-regulated, whereas multiple 9-LOX pathway genes down-regulated in lox5-3 mutant in response to F. graminearum infection. Furthermore, oxylipin profiling of the mutant and corresponding wild type, B73, as well as a more resistant line, W438, uncovered significantly higher contents of JA-isoleucine (JA-Ile) and other jasmonates but relatively lower levels of 9-oxylipins in lox5-3 upon infection. By contrast, resistant line W438 and B73 displayed relatively lower levels of JAs, yet considerable increase of 9-oxylipins. Taken together, these results clearly indicated that the signaling pathways of 9-oxylipins and JAs antagonize each other, and that while ZmLOX5-produced 9-oxylipins contribute to resistance, JAs are likely to function as negative regulator in maize defense against GSR.

Collagen induced arthritis in dba/1j mice associates with oxylipin changes in plasma

Project description:Oxylipins play important roles in various biological processes and are considered as mediators of inflammation for a wide range of diseases such as rheumatoid arthritis (RA). The purpose of this research was to study differences in oxylipin levels between a widely used collagen-induced arthritis (CIA) mice model and healthy control (Ctrl) mice. DBA/1J male mice (age: 6-7 weeks) were selected and randomly divided into two groups, viz. a CIA- and a Ctrl group. The CIA mice were injected intraperitoneal (i.p.) with the joint cartilage component collagen type II (CII) and an adjuvant injection of lipopolysaccharide (LPS). Oxylipin metabolites were extracted from plasma for each individual sample using solid phase extraction (SPE) and were detected with high performance liquid chromatography/tandem mass spectrometry (HPLC-ESI-MS/MS), using dynamic multiple reaction monitoring (dMRM). Both univariate and multivariate statistical analysis was applied. The results in univariate student's t-test revealed 10 significantly up- or down-regulated oxylipins in CIA mice, which were supplemented by another 6 additional oxylipins, contributing to group clustering upon multivariate analysis. The dysregulation of these oxylipins revealed the presence of ROS-generated oxylipins and an increase of inflammation in CIA mice. The results also suggested that the Collagen-induced arthritis might associate with dysregulation of apoptosis, possibly inhibited by activated NF- κ B because of insufficient PPAR-γ ligands.

Nocturnal expression data of Synechococcus in WT and kaiABC-null strains

Project description:In the unicellular cyanobacterium, Synechococcus elongatus PCC 7942, most of genes are downregulated in the dark, while 10% of genes are upregulated. Here, we employed high-density oligonucleotide arrays to explore comprehensive profiles of genome-wide Synechococcus gene expression in wild type and kaiABC-null strains under continuous dark (DD) conditions. We found that expression profile of a subset of genes on the genome in DD was dramatically affected by kaiABC-nullification, and the magnitude of dark-induction was dependent on time when cells were transferred from light to DD Keywords: timecourse data (0-12 h) under continuous darkness after dark:light cycles from Synechococcus elongatus PCC 7942 wild type and kaiABC-null strains Wild type (WT) and kaiABC-null (DkaiABC) S. elongatus PCC 7942 strains were analyzed under continuous dark (DD) conditions after two 12h:12h light:dark (LD) cycles using Affymetrix high-density oligonucleotide microarrays (GeneChip CustomExpress Arrays) representing predicted 2,515 protein-coding genes on the genome of Synechococcus elongatus PCC 6301, which can be used also to the almost homologous strain, S. elongatus PCC 7942: Two independent experiments in WT and Dkai strains under DD (hours 0, 0.5, 1, 2, 4, 8 and 12).

Obesity reprograms the pulmonary polyunsaturated fatty acid-derived lipidome prior to injury in a diet-dependent manner

Project description:Obesity exacerbates inflammation upon lung injury; however, the mechanisms by which obesity primes pulmonary dysregulation prior to injury are not well studied. Notably, little is known about how obesity dysregulates pulmonary polyunsaturated fatty acid (PUFA) metabolism that is central to inflammation initiation and resolution. Herein, we first show that a high fat diet (HFD) administered to C57BL/6J mice increases the relative abundance of pulmonary PUFA-containing triglycerides and the concentration of PUFA-derived oxylipins, independent of an increase in total pulmonary PUFAs, prior to onset of pulmonary inflammation. Experiments with a genetic model of obesity did not recapitulate the effects of the HFD on the pulmonary oxylipin signature, revealing a diet-driven effect. Subsequent pulmonary next-generation RNA sequencing identified complex and unique transcriptional regulation with the HFD. The HFD increased pathways related to glycerophospholipid metabolism and immunity, including an elevation in B cell differentiation and signaling. Finally, computational integration of lipidomic with transcriptomic data revealed novel HFD-driven networks between glycerophospholipid metabolism and B cell receptor signaling with specific PUFA-derived oxylipins. Collectively, these data show obesity dysregulates pulmonary PUFA metabolism prior to lung injury, which may be a mechanism by which obesity primes the lungs to respond poorly upon infectious and/or inflammatory challenges.

Mapping and dynamics of regulatory DNA and transcription factor networks in A. thaliana

Project description:We mapped DNaseI hypersensitive sites (DHSs) and applied genomic footprinting to define in vivo transcription factor (TF) occupancy at nucleotide resolution across the A. thaliana genome in whole seedlings during heat- and light-response states. We find that trait-associated variation localizes within DHSs, and that extensive TF occupancy within protein-coding exons has shaped A. thaliana codon usage. Analysis of >700,000 TF footprints disclosed an extensive cis-regulatory lexicon, and enabled construction of large-scale TF cross-regulatory networks. Although the cis- and trans-regulatory repertoire is markedly distinct from mammals, the architecture of A. thaliana TF networks is strikingly similar to those of human. Analysis of the DHS landscape and TF network dynamics during heat shock and photomorphogenesis revealed thousands of conditionally-sensitive elements and enabled mapping of key regulatory circuits. Our results provide an extensive resource for understanding and enabling diverse aspects of A. thaliana biology. Chromatin accessibility profiling (Dnase I-seq) and RNA-seq of 7-day-old dark-grown seedlings exposed to 0hr light, 30min light, 3hr light or 24hr LD conditions. Chromatin accessibility profiling (Dnase I-seq) and RNA-seq of 7-day-old LD-grown seedlings treated with a brief sever heat shock or kept under control conditions. Replicates are included when available; controls and read-normalized samples (samples that were subsampled to the same read-depth) are also included here.
