Project description:During early pregnancy, glucose is essential for the uterine epithelium and the developing embryo. In cows, studies have shown that progesterone increases the secretion of glucose into the uterine lumen. Nevertheless, how progesterone affects glucose metabolism in the uterine epithelium has been sparsely investigated. Therefore, our objective was to investigate how progesterone influences glucose metabolism in immortalized bovine uterine epithelial (BUTE) cells. Progesterone treatment (10 μM) increased glucose consumption. To gain a more global picture of the effects of progesterone, RNAseq was performed after BUTE cells were treated with vehicle (DMSO) or 10 μM for 24 hours. KEGG analysis indicated that progesterone altered genes associated with metabolic pathways and glutathione metabolism. Manually examining genes unique to specific glucose metabolic pathways identified an increase in the rate-limiting enzyme in the pentose phosphate pathway—glucose-6-phosphate dehydrogenase. Functionally, a major product of the pentose phosphate pathway is NADPH, and progesterone treatment increased NADPH concentrations in BUTE cells. In cows, immunohistochemistry confirmed that glucose-6-phosphate dehydrogenase levels were higher in the uterine epithelium in the luteal phase when progesterone concentrations are high. In conclusion, progesterone increased glucose-6-phosphate dehydrogenase expression and metabolism via the pentose phosphate pathway in the bovine uterine epithelium. This metabolism could provide substrates for cell proliferation, molecules to be secreted into the uterine lumen that supports embryonic development, or maintain reduction/oxidation balance in the uterine epithelium.

Project description:By an evolutionary approach based on long-term culture on gluconate as the sole carbon source, a Saccharomyces cerevisiae wine strains with enhanced flux through the pentose phosphate (PP) pathway were obtained. One of these evolved strains, ECA5, exhibited several novel properties with great potential for wine making, including a higher than wild-type fermentation rate and altered production of acetate and aroma compounds. To describe the mechanisms underlying this complex phenotype, we performed a comparative analysis of transcriptomic profiles between ECA5 and its ancestral strain, EC1118, under low nitrogen, wine fermentation conditions.

Project description:Evolutionary engineering strategy was used for selection of ethanol-tolerant Saccharomyces cerevisiae clones under gradually increasing ethanol stress levels. Clones B2 and B8 were selected based on their higher ethanol-tolerance and higher ethanol production levels. Whole genome microarray analysis was used for identifying the gene expression levels of these two evolved clones compared to the reference strain. Two evolved ethanol-tolerant strains B2 and B8, which were selected by evolutionary engineering under gradually increasing ethanol stress, were used for whole genome transcriptomic analysis in comparison with the reference strain. Cells were grown in yeast minimal media until they reach a final OD600 of 1. Following total RNA isolation, gene expression levels were analyzed using One-color microarray-based gene expression analysis (Agilent Technologies). Experiments were done in triplicates.

Project description:The circadian clock is a ubiquitous timekeeping system that organizes the behavior and physiology of organisms over the day and night. The clockwork orchestrates a multitude of metabolic processes as illustrated by previous global transcriptomics and proteomics studies, and the existence of daily rhythms of reduction and oxidation (redox) in a range of diverse species. However, the reciprocal question of whether metabolism can alter the clockwork remains largely unaddressed. Here we identify the pentose phosphate pathway (PPP), a critical source of cellular reducing power in the form of NADPH, as an important modulator of circadian oscillations. We show that genetic and pharmacologic inhibition of the PPP perturbs circadian gene expression and metabolic rhythms in human cells. Pharmacologic inhibition of the PPP caused similar effects in mouse tissues, and altered the pattern of rhythmic behavior in Drosophila. These manipulations also altered genome wide DNA-binding activity of the circadian transcription factors BMAL1 and CLOCK through a mechanism likely involving the redox-sensitive histone acetyltransferase p300. Thus, disruption of the PPP regulates circadian rhythms via modulation of NADPH metabolism, highlighting redox reactions as a novel connector of metabolic cycles and transcriptional oscillations in nucleated cells.

Project description:Metabolic pathways are now considered as intrinsic virulence attributes of pathogenic bacteria and hence represent potential targets for anti-bacterial strategies. Here, we addressed the role of the pentose phosphate pathway (PPP) and its connections with other metabolic pathways in the pathophysiology of Francisella novicida. We have previously shown that this intracellular bacterial pathogen used gluconeogenesis to metabolize host-derived nutrients in the cytosolic compartment of infected macrophages. Francisella species, which lacks the oxidative branch of the PPP, are equipped with all the genes of the non-oxidative branch (i.e. tktA, tal, rpiA and rpe, encoding transketolase, transaldolase, ribose-phosphate isomerase and ribulose phosphate epimerase, respectively). The involvement of the PPP in the early stage of intracellular life cycle of F. novicida was first demonstrated with the study of PPP inactivation mutants. Indeed, inactivation of tktA, rpiA or rpe genes, severely impaired intramacrophagic multiplication during the first 24–hours. However, time-lapse video microscopy demonstrated that rpiA and rpe mutants were able to resume late intracellular bacterial multiplication. To get further insight into the links between the PPP and other metabolic networks of the bacterium, we next performed a thorough proteo-metabolomic analysis of these mutants. We show that the PPP constitutes a major bacterial metabolic hub with multiple connections with glycolysis, tricarboxylic acid cycle and other metabolic pathways, such as fatty acid degradation and sulfur metabolism. Hence, our study highlights how, by its multiple connections with other metabolic pathways, PPP is instrumental to Francisella pathogenesis and growth in its intracellular niche.

Project description:Metabolic reprogramming has emerged as a crucial regulator of immune cell activation but how systemic metabolism influences immune cell metabolism and function remains to be investigated. To investigate the effect of dyslipidemia on immune cell metabolism, we performed in-depth transcriptional, metabolic and functional characterization of macrophages isolated from hypercholesterolemic mice. Systemic metabolic changes in such mice alter cellular macrophage metabolism and attenuate inflammatory macrophage responses. In addition to diminished maximal mitochondrial respiration, hypercholesterolemia reduces the LPS-mediated induction of the pentose phosphate pathway (PPP) and the Nrf2-mediated oxidative stress response. Our observation that suppression of the PPP diminishes LPS-induced cytokine secretion supports the notion that this pathway contributes to inflammatory macrophage responses. Overall, this study reveals that systemic and cellular metabolism are strongly interconnected, together dictating macrophage phenotype and function.

Abstract:
We present the quantification and kinetic characterisation of the enzymes of the pentose phosphate pathway in Saccharomyces cerevisiae. The data are combined into a mathematical model that describes the dynamics of this system and allows for the predicting changes in metabolite concentrations and fluxes in response to perturbations. We use the model to study the response of yeast to a glucose pulse. We then combine the model with an existing glycolysis one to study the effect of oxidative stress on carbohydrate metabolism. The combination of these two models was made possible by the standardized enzyme kinetic experiments carried out in both studies. This work demonstrates the feasibility of constructing larger network models by merging smaller pathway models.
