Project description:Plant cellular damage promotes the interaction of lipoxygenases (LOX) with free fatty acids to yield 9- and 13-hydroperoxides which are further metabolized into diverse oxylipins. The enzymatic action of 13-LOX on linolenic acid enables production of 12-oxo-phytodienoic acid (12-OPDA) and its downstream products, jointly known as jasmonates. As signals, jasmonates have related yet distinct roles in the regulation of plant resistance against insect and pathogen attack. An additional and conceptually parallel pathway involving 9-LOX activity on linoleic acid leads to the production of 10-oxo-11-phytoenoic acid (10-OPEA). Despite structural similarity to jasmonates, physiological roles for 10-OPEA have remained unclear. Both 12-OPDA and 10-OPEA equally promote the transcription of numerous defense genes encoding glutathione S-transferases, cytochrome P450s, and pathogenesis-related proteins; however, 10-OPEA activity diverges in the context of reduced protease inhibitor transcript accumulation. To identify additional differential responses, we subsequently performed whole transcriptome analyses using RNAseq. These comparisons provide a platform for further examination of plant response specificity to the cyclopentenone 10-OPEA. A total of 12 samples were analyzed, comprised of two treatments (10-OPEA and 12-OPDA) and a DMSO carrier control (5%DMSO/0.1%Tween 20 in H20), all in replicates of four.

Project description:The irreversible decarboxylation step, which commits 2-oxo acids to the Ehrlich pathway, was initially attributed to pyruvate decarboxylase. However, the yeast genome was shown to harbour no fewer than 5 genes that show sequence similarity with thiamine-diphosphate dependent decarboxylase genes. Three of these (PDC1, PDC5 and PDC6) encode pyruvate decarboxylases { while ARO10 and THI3 represent alternative candidates for Ehrlich-pathway decarboxylases. Transcriptome analysis and decarboxylase activity measurements on an S. cerevisiae aro10 strain, a double aro10 thi3 deletion strain and a quadruple pdc1,5,6,aro10 mutant strains grown in carbon–limited chemostat with phenylalanine as nitrogen source indicated that: i) PDC5 is strongly upregulated in an aro10 background (Fig. 2) and also encodes a broad-substrate α-keto acid decarboxylase. ii) PDC5 expression depends on the presence of THI3 (Fig. 2), and iii) in contrast to cell extracts from a strain expressing ARO10 only (pdc1,5,6, thi3), cell extract from a strain that only contains THI3 (pdc1,5,6,aro10) did not produce any α-keto acid decarboxylase activity . THI3 has recently been demonstrated to be involved in regulation of thiamine homeostasis in S. cerevisiae, which further suggests that its role in the Ehrlich pathway may be regulatory rather than catalytic. A systematic investigation of the catalytic properties of all five (putative) TPP-dependent decarboxylases (Aro10p, Thi3p, Pdc1p, Pdc5p, Pdc6p) is essential for a final resolution of the substrate specificity of these key enzymes in the Ehrlich pathway.

Project description:Time-restricted feeding improves metabolic health independently of dietary macronutrient composition or energy restriction. To understand the mechanisms underpinning the effects of time-restricted feeding, we investigated the metabolic and transcriptomic profile of skeletal muscle and serum samples from 11 overweight/obese men. In muscle, 4-10% of transcripts and 14% of metabolites were periodic, with the amplitude of the metabolites lower after time-restricted feeding. Core clock genes were unaltered by either intervention, while time-restricted feeding induced rhythmicity of genes related to lipid and amino acid transport. In serum, 49-65% of the metabolites had diurnal rhythms across both conditions, with the majority being lipids. Time-restricted feeding shifted the skeletal muscle metabolite profile from predominantly lipids to amino acids. Our results show time-restricted feeding differentially affects the amplitudes and rhythmicity of serum and skeletal muscle metabolites, and regulates the rhythmicity of genes controlling lipid and amino acid transport, without perturbing the core clock.

Project description:We analyzed anterior halves of NF stage 15 embryos that were treated with 10uM DMSO (control), or 1uM RA and 10uM 4-oxo-RA (experimental) for changes in gene expression induced by the two mophogens. RNA-sequencing revealed significant overlap in genes upregulated by both RA and 4-oxo-RA, and to a lesser extent, those downregulated by them. We report all Zic-1 targets described in accompanying manuscript to be regulated by both RA and 4-oxo-RA.
