Nitrogen limitation reveals large reserves in metabolic and translational capacities of yeast.

Cells maintain reserves in their metabolic and translational capacities as a strategy to quickly respond to changing environments. Here we quantify these reserves by stepwise reducing nitrogen availability in yeast steady-state chemostat cultures, imposing severe restrictions on total cellular protein and transcript content. Combining multi-omics analysis with metabolic modeling, we find that seven metabolic superpathways maintain >50% metabolic capacity in reserve, with glucose metabolism maint ...[more]

Quantifying gene expression control by growth and metabolism reveals distinct regulation of central carbon metabolism genes in yeast

Project description:Here we quantitatively describe the influence of cell growth rate and amino acid metabolic context on gene expression in the eukaryal model organism Saccharomyces cerevisiae. We show that growth rate and metabolic cues regulate ~70% of the yeast transcriptome and proteome, thereby exerting gene expression control in a global manner. We find that the growth rate-dependent differential gene expression largely reflects changing availabilities of the mRNA and protein synthesis machineries, while metabolic cues influences gene expression through the availabilities of amino acids and nucleotides. Genes in central carbon metabolism, however, are regulated independently of these global physiological controls, demonstrating distinct mechanisms to control their expression levels.

Loss of RET promotes mesenchymal identity in neuroblastoma cells

Project description:Aberrant activation of Anaplastic Lymphoma Kinase (ALK) drives neuroblastoma (NB). Previous work has identified the RET receptor tyrosine kinase (RTK) as a downstream target of ALK activity in NB models. We show here that ALK activation in response to ALKAL2 ligand results in the rapid phosphorylation of RET in NB cells, providing additional insight into the contribution of RET to the ALK driven gene signature in NB. To further address the role of RET in NB, RET knock-out (KO) SK-N-AS cells were generated by CRISPR/Cas9 genome engineering. Gene expression analysis of RET KO NB cells identified a reprogramming of NB cells to a mesenchymal (MES) phenotype that was characterized by increased migration and upregulation of the AXL and MET RTKs as well as integrins and extracellular matrix components. Strikingly, the upregulation of AXL in the absence of RET reflects the development timeline observed in the neural crest as progenitor cells undergo differentiation during embryonic development. Together, these findings suggest that a MES phenotype is promoted in mesenchymal NB cells in the absence of RET, reflective of a less differentiated developmental status.

Proteome re-allocation in amino acid supplemented S. cerevisiae using TMT-based quantitative proteomics

Project description:In recent years, more attention in systems biology has been given to the concept of protein constraints and the cell’s necessity to allocate its proteome between important processes. From this point of view, attempts to elucidate cellular maximum capacity of growth as a function of protein availability has been investigated. Elucidating the possibility of optimizing cell proliferation, by tailoring proteome allocation. To experimentally investigate this concept further we cultivated Saccharomyces cerevisiae in bioreactors with or without amino acid supplementation and performed proteomics to analyze global changes in proteome allocation, during anaerobic as well as aerobic growth on glucose. Analysis of proteomic data implies that proteome mass is mainly being re-allocated from amino acid biosynthetic processes into translation, in regard to absolute levels of change, accompanied by an increased growth rate during supplementation. Similar findings were obtained from both aerobic and anaerobic cultivations, and subsequently independent of the two examined metabolic states. Indicating the possibility of increasing growth rate through freeing up proteome mass and increasing proteome allocation towards translational machinery.

Suppressors of amyloid-beta toxicity improve recombinant protein production by reducing oxidative stress and tunning cellular metabolism

Project description:In this study, we used a yeast Alzheimer’s disease model in which amyloid-β peptides (Aβ42) accumulate and induce stress-related phenotypes similar to overexpression of recombinant proteins. We validated that suppressors of Aβ42 cytotoxicity could reduce cell stress and improve recombinant protein production. Omics analyses and reverse metabolic engineering reveal potential regulatory hubs in cellular metabolism and protein synthesis, which may provide guidelines for engineering other cell factories for efficient protein production.
